Drug Interactions

Major
Wellbutrin Xl + Zoloft

The following applies to the ingredients: Bupropion (found in Wellbutrin Xl) and Sertraline (found in Zoloft)

ADJUST DOSE: Coadministration of bupropion may elevate the plasma concentrations of drugs metabolized by CYP450 2D6. The proposed mechanism is decreased clearance due to bupropion's inhibition of CYP450 2D6 activity. In a study of 15 male volunteers who were extensive metabolizers of CYP450 2D6, administration of a single 50 mg dose of desipramine following treatment with bupropion 150 mg twice daily increased the desipramine peak plasma concentration (Cmax), systemic exposure (AUC) and half-life by an average of 2-, 5-, and 2-fold, respectively. The effect was present for at least 7 days after the last dose of bupropion. In addition, when combined with serotonergic drugs, such as certain selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), or tricyclic antidepressants (TCAs) that are CYP450 2D6 substrates, elevated plasma levels may potentiate the risk of a potentially life-threatening condition called serotonin syndrome. In a case report of a 62-year-old woman with depression, serotonin syndrome developed after three weeks of bupropion and sertraline therapy, initially misdiagnosed as worsening depression and treated with venlafaxine, leading to further symptom progression. The patient recovered after discontinuing the offending medications and treating for serotonin syndrome, with authors highlighting bupropion's role in increasing SSRI levels through CYP450 2D6 inhibition. Symptoms of serotonin syndrome include altered mental status, hypertension, restlessness, myoclonus, hyperthermia, hyperreflexia, diaphoresis, shivering, and tremor.

MONITOR CLOSELY: The use of bupropion is associated with a dose-related risk of seizures. The risk may be further increased when coadministered with serotonergic agents that can reduce the seizure threshold such as certain selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), or tricyclic antidepressants (TCAs). These agents are often individually epileptogenic and may have additive effects when combined. The estimated incidence of seizures is approximately 0.4% for immediate-release bupropion hydrochloride at dosages between 300 to 450 mg/day (equivalent to 348 to 522 mg/day of bupropion hydrobromide) but increases almost tenfold between 450 mg and 600 mg/day (equivalent to 522 and 696 mg/day of bupropion hydrobromide). Data for sustained-release (SR) bupropion hydrochloride revealed a seizure incidence of approximately 0.1% at dosages up to 300 mg/day and 0.4% at 400 mg/day. Likewise, in clinical trials, an overall seizure incidence of approximately 0.1% has been reported with extended-release (XL) bupropion hydrochloride at dosages up to 450 mg/day and approximately 0.39% at 450 mg/day. The 0.4% seizure incidence may exceed that of other marketed antidepressants by as much as 4-fold.

MANAGEMENT: According to bupropion product labeling, if coadministration of bupropion with CYP450 2D6 substrates is required, concomitant medications should be initiated at the lower end of the dose range. If the concomitant agents possess serotonergic activity (e.g., SSRIs, SNRIs, and/or TCAs) patients should be monitored more closely for and counseled about the signs and symptoms of serotonin syndrome (e.g., altered mental status, hypertension, restlessness, myoclonus, hyperthermia, hyperreflexia, diaphoresis, shivering, and tremor). Additionally, if the coadministered agent is known to lower the seizure threshold, extreme caution is advised particularly in the elderly and in patients with a history of seizures or other risk factors for seizures (e.g., head trauma; brain tumor; severe hepatic cirrhosis; metabolic disorders; CNS infections; excessive use of alcohol or sedatives; addiction to opiates, cocaine, or stimulants; diabetes treated with oral hypoglycemic agents or insulin). Bupropion as well as concomitant medications should be initiated at the lower end of the dosage range and titrated gradually as needed and as tolerated. The maximum recommended dosage for the specific bupropion formulation should not be exceeded. Bupropion should be discontinued and not restarted in patients who experience a seizure during treatment.

Drug and Food Interactions

Moderate
Wellbutrin Xl + Food

The following applies to the ingredients: Bupropion (found in Wellbutrin Xl)

GENERALLY AVOID: Excessive use or abrupt discontinuation of alcohol after chronic ingestion may precipitate seizures in patients receiving bupropion. Additionally, there have been rare postmarketing reports of adverse neuropsychiatric events or reduced alcohol tolerance in patients who drank alcohol during treatment with bupropion. According to one forensic report, a patient died after taking large doses of both bupropion and alcohol. It is uncertain whether a drug interaction was involved. Single-dose studies in healthy volunteers given bupropion and alcohol failed to demonstrate either a significant pharmacokinetic or pharmacodynamic interaction.

MANAGEMENT: The manufacturer recommends that alcohol consumption be minimized or avoided during bupropion treatment. The use of bupropion is contraindicated in patients undergoing abrupt discontinuation of alcohol.

The following applies to the ingredients: Bupropion (found in Wellbutrin Xl)

MONITOR: Additive or synergistic effects on blood pressure may occur when bupropion is combined with sympathomimetic agents such as nasal decongestants, adrenergic bronchodilators, ophthalmic vasoconstrictors, and systemic vasopressors. Treatment with bupropion can result in elevated blood pressure and hypertension. In clinical practice, hypertension, in some cases severe and requiring acute treatment, has been observed in patients receiving bupropion alone and in combination with nicotine replacement therapy. These events have occurred in both patients with and without evidence of preexisting hypertension. Furthermore, postmarketing cases of hypertensive crisis have been reported during the initial titration phase with bupropion-naltrexone treatment.

MANAGEMENT: Caution is advised when bupropion is used with other drugs that increase dopaminergic or noradrenergic activity due to an increased risk of hypertension. Blood pressure and heart rate should be measured prior to initiating bupropion therapy and monitored at regular intervals consistent with usual clinical practice, particularly in patients with preexisting hypertension. Dose reduction or discontinuation of bupropion should be considered in patients who experience clinically significant and sustained increases in blood pressure or heart rate.

The following applies to the ingredients: Bupropion (found in Wellbutrin Xl)

MONITOR: The concomitant use of bupropion and nicotine replacement for smoking cessation may increase the risk of hypertension. In a clinical study (n=250), 6.1% of patients who used sustained-release bupropion with nicotine transdermal system developed treatment-emergent hypertension, compared to 2.5% of patients treated with bupropion alone, 1.6% treated with nicotine alone, and 3.1% treated with placebo. Three patients in the bupropion plus nicotine group and one patient in the nicotine-only group discontinued treatment due to hypertension. The majority had evidence of preexisting hypertension.

MANAGEMENT: Blood pressure monitoring is recommended for patients concomitantly using bupropion and nicotine replacement for smoking cessation.

Moderate
Zoloft + Food

The following applies to the ingredients: Sertraline (found in Zoloft)

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of sertraline. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills. In addition, limited clinical data suggest that consumption of grapefruit juice during treatment with sertraline may result in increased plasma concentrations of sertraline. The proposed mechanism is inhibition of CYP450 3A4-mediated metabolism by certain compounds present in grapefruit. An in-vitro study demonstrated that grapefruit juice dose-dependently inhibits the conversion of sertraline to its metabolite, desmethylsertraline. In a study with eight Japanese subjects, mean plasma levels of sertraline increased by approximately 100% and maximum plasma concentrations increased by 66% after the ingestion of three 250 mL glasses of grapefruit juice per day for 5 days and administration of a single dose of sertraline 75 mg on the sixth day. In another small study with 5 patients, mean sertraline trough levels increased by 47% after taking sertraline for at least 6 weeks, then taking sertraline with 240 mL grapefruit juice daily for 1 week. The clinical significance is unknown; however, pharmacokinetic alterations associated with interactions involving grapefruit juice are often subject to a high degree of interpatient variability. The possibility of significant interaction in some patients should be considered.

MANAGEMENT: Patients receiving sertraline should be advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how sertraline affects them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities. Some authorities recommend that consumption of grapefruit juice should be avoided during sertraline therapy.

Drug and Pregnancy Interactions

The following applies to the ingredients: Bupropion (found in Wellbutrin Xl)

This drug should be used during pregnancy only if the potential benefit outweighs the potential risk to the fetus. Smoking cessation without the use of medications is advisable during pregnancy.

AU TGA pregnancy category: B2
US FDA pregnancy category: C

Comments:
-A pregnancy exposure registry is available.
-Neonates exposed to this drug late in the third trimester may require respiratory support, tube feeding, and/or prolonged hospitalization.
-Exposed neonates should be monitored after delivery for direct toxic effects of this drug, drug discontinuation syndrome, and serotonin syndrome (e.g.,. respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypo/hypertonia, hyperreflexia, tremor, jitteriness, irritability, constant crying).

High dose animal studies have failed to reveal evidence of specific teratogenic effects. Low dose animal studies in rabbits have reported a slightly increased incidence of fetal malformations and skeletal variations. Epidemiological studies of pregnant women exposed to bupropion in the first trimester show no increased risk of congenital malformations overall.

Data from the international bupropion pregnancy register (675 trimester exposures) and a retrospective cohort study using the United Healthcare database (1,213 first trimester exposures) and a case-control study from the National Birth Defects Prevention Study (6,853 infants with cardiovascular malformations and 5,763 with non-cardiovascular malformations) did not show an increased risk for malformations overall after bupropion exposure during the first trimester. A retrospective database of infants (n=7005) whose mothers were exposed to bupropion in the first trimester and outside of the first trimester also failed to reveal an increased risk for congenital malformation, especially cardiovascular malformation. Study findings on the risk for left ventricular outflow tract obstruction and ventricular septal defect after first trimester exposure to bupropion are inconclusive.

To monitor maternal-fetal outcomes of pregnant women exposed to antidepressant therapy, a National Pregnancy Registry for Antidepressants has been established. Healthcare providers are encouraged to prospectively register patients. For additional information: https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/antidepressants/

AU TGA pregnancy category B2: Drugs which have been taken by only a limited number of pregnant women and women of childbearing age, without an increase in the frequency of malformation or other direct or indirect harmful effects on the human fetus having been observed. Studies in animals are inadequate or may be lacking, but available data show no evidence of an increased occurrence of fetal damage.

US FDA pregnancy category C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.

The following applies to the ingredients: Sertraline (found in Zoloft)

This drug should be used during pregnancy only if the potential benefit outweighs the potential risk to the fetus, taking into account the risks of untreated depression.
-Oral concentrate and solution formulations containing alcohol: Not recommended.

AU TGA pregnancy category: C
US FDA pregnancy category: Not assigned.

Risk summary: Malformative risk is unlikely when given during the first trimester. There is inconclusive data on use of this drug in the third trimester to inform of a drug-related risk.

Comments:
-A pregnancy exposure registry is available.
-Neonates exposed to this drug late in the third trimester may require respiratory support, tube feeding, and/or prolonged hospitalization.
-Exposed neonates should be monitored after delivery for direct toxic effects of this drug, drug discontinuation syndrome, and serotonin syndrome (e.g., respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypo/hypertonia, hyperreflexia, tremor, jitteriness, irritability, constant crying).

Animal studies have failed to reveal evidence of teratogenicity; however, there was evidence of delayed ossification and effects on reproduction attributed to maternal toxicity. Decreased neonatal survival following maternal administration at exposures similar to or slightly greater than the maximum recommended human dose of 200 mg was also observed; the clinical significance is unknown. There are no controlled data in human pregnancy.

The results of several studies suggest that the use of SSRIs in the first trimester of pregnancy may be associated with an increased risk of cardiovascular and/or other congenital malformations; however, this association has not been clearly established. The association appears to be strongest for another SSRI, paroxetine.

Use of sertraline during pregnancy has been reported to cause symptoms compatible with withdrawal reactions in neonates whose mothers had taken sertraline. Neonates exposed to SSRIs and SNRIs late in the third trimester have uncommonly reported clinical findings including respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying. These effects have mostly occurred either at birth or within a few days of birth. These features are consistent with either a direct toxic effect of SSRIs and SNRIs, or possibly a drug discontinuation syndrome; in some cases, the clinical picture is consistent with serotonin syndrome. The results of a cohort study indicate that 30% of neonates who had prolonged exposure to SSRIs in utero experience symptoms, in a dose-response manner, of a neonatal abstinence syndrome after birth. The authors suggest that infants exposed to SSRIs should be closely monitored for a minimum of 48 hours after birth.

Epidemiological data have suggested that the use of SSRIs, particularly in late pregnancy, may increase the risk of persistent pulmonary hypertension in the newborn. Data are not available for SNRIs.

One study compared 267 women exposed to an SSRI - either fluvoxamine, paroxetine, or sertraline, to 267 controls. Exposure to SSRIs was not associated with either increased risk for major malformations, higher rates of miscarriage, stillbirth, or prematurity. Mean birth weights among SSRI users were similar to controls as were the gestational ages. The study concluded that the SSRIs fluvoxamine, paroxetine, and sertraline did not appear to increase teratogenic risk when used in their recommended doses.

Animal data with sertraline have not shown an effect on fertility. Human case reports from some SSRIs have shown an effect on sperm quality that is reversible. As yet, the impact of this on human fertility has not been observed.

To monitor maternal-fetal outcomes of pregnant women exposed to antidepressant therapy, a National Pregnancy Registry for Antidepressants has been established. Healthcare providers are encouraged to prospectively register patients. For additional information: https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/antidepressants/

AU TGA pregnancy category C: Drugs which, owing to their pharmacological effects, have caused or may be suspected of causing, harmful effects on the human fetus or neonate without causing malformations. These effects may be reversible. Accompanying texts should be consulted for further details.

US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.

Drug and Breastfeeding Interactions

The following applies to the ingredients: Bupropion (found in Wellbutrin Xl)

A decision should be made to discontinue nursing or discontinue the drug, taking into account the benefit of breast-feeding to the infant and the importance of the drug to the mother.
-Some experts recommend: Use with caution.

Excreted into human milk: Yes

Comment: Another drug may be preferred, particularly when breastfeeding a newborn or preterm infant.

There is limited information that maternal bupropion at oral doses up to 300 mg daily produces low levels in breastmilk. It is not generally expected to cause adverse effects in breastfed infants; however, there are case reports of possible seizure in partially breastfed 6-month-olds. Alternate drugs that may be considered in place of bupropion include nortriptyline, paroxetine, and sertraline.

One case report has suggested that bupropion accumulates in human breast milk in concentrations much greater than in maternal plasma. At least two metabolites of bupropion are also detectable in human milk. However, in the plasma of one nursing infant whose mother took bupropion, neither bupropion nor its metabolites could be detected.

Data from a lactation study in 10 women showed breastmilk levels of 45.2 mcg/L for bupropion, and 104.6 mcg/mL, 72.1 mcg/mL, and 459 mcg/mL for it metabolites hydroxybupropion, erythrohydroxybupropion, and threohydroxybupropion, respectively. The authors of this study estimated that an exclusively breastfed infant would receive an average of 0.2% of the maternal weight-adjusted dose of bupropion and an average of 2% of the maternal weight-adjusted dosage of bupropion plus metabolites.

The following applies to the ingredients: Sertraline (found in Zoloft)

Use is not recommended; benefit to the mother should outweigh risk to the infant.

Excreted into human milk: Yes

Comments:
-This drug has been considered one of the preferred antidepressants during breastfeeding.
-Accumulation of the drug may occur in preterm infants with impaired metabolic activity; effects similar to neonatal abstinence may rarely present in these infants.
-Mothers taking an SSRI during pregnancy and postpartum may have difficulty breastfeeding and may require additional breastfeeding support.

Benign neonatal sleep myoclonus in a 4-month-old infant and agitation in that spontaneously resolved in another infant was reported to the Australian Adverse Drug Reaction Advisory Committee and may be related to the presence of sertraline in breastmilk.

Levels of sertraline in breastmilk are reported to be low; the weakly active metabolite desmethylsertraline may be detectable in low levels. In a study of 26 breastfeeding women who were, on average, 15.8 weeks postpartum and receiving an average of 124 mg sertraline daily for at least 14 days for severe depression, complete sets of milk sample data were available for 15 mothers. Analysis of these samples led the study authors to estimate that an exclusively breastfed infant would receive an average of 0.54% of the maternal weight-adjusted dosage. Pumping and discarding milk 8 to 9 hours after the mother's dose would decrease the infant's daily dosage by 17%.

Amounts of sertraline ingested by breastfed infants are reported to be small. There was an analysis of 30 breastfed infants aged 6 to 13 weeks, of which 19 were exclusively breastfed and 11 breastfed at least half the time. Serum sertraline levels were below 1 mcg/L in 22 infants. The other 8 infants had an average serum sertraline level of 7.9 mcg/L; their mothers were taking a average of 109 mg sertraline daily, with an average serum level of 52.8 mcg/L.

The data from one study on three breast-fed infants suggested that sertraline and/or its almost inactive metabolite norsertraline may be present at very low concentrations in the plasma of breast-fed infants. No adverse effects were noted in the infants.

A pooled analysis of 53 mother-infant pairs from published and unpublished cases found that infants had an average of 2% of the sertraline plasma levels of the mothers'; three of the infants had a plasma level greater than 10% of the mothers'.

A study of fourteen mother-infant pairs reported that while mothers receiving clinical doses of sertraline experienced substantial blockade of the platelet 5-HT transporter, platelet 5-HT uptake in nursing infants of treated mothers was unaltered.

Another study of twelve breast-feeding mothers reported that both sertraline and desmethylsertraline were present in all breast milk samples. Detectable levels of sertraline were reported in three nursing infants and detectable levels of desmethylsertraline were reported in six infants.

A case study of a mother breast-feeding while receiving sertraline therapy has also been reported. The drug was found to be present in the mother's milk. However, no sertraline was detected in the infant's serum and no abnormal occurrences were noted in the development of this infant either.
