Drug Interactions
Major
Sertraline
+ Vyvanse
The following applies to the ingredients: Sertraline and Lisdexamfetamine (found in Vyvanse)
GENERALLY AVOID: Several case reports suggest that serotonin reuptake inhibitors may potentiate the pharmacologic response to sympathomimetic agents. The exact mechanism of interaction is unclear. In one case report, a patient experienced jitteriness, racing thoughts, stomach cramps, dry eyes, palpitations, tremors, and restlessness following a single dose of phentermine ingested approximately a week after she had discontinued fluoxetine. Because of the long half-life of fluoxetine and its metabolite, an interaction with fluoxetine is possible. Similar toxic reactions have been reported when fluoxetine was used concomitantly with amphetamine or phenylpropanolamine. Additionally, some sympathomimetic agents such as amphetamines may possess serotonergic activity and should generally not be administered with serotonin reuptake inhibitors because of the additive risk of serotonin syndrome, which is a rare but serious and potentially fatal condition thought to result from hyperstimulation of brainstem 5-HT1A and 2A receptors. The interaction was suspected in a patient treated with dexamphetamine who developed symptoms consistent with the serotonin syndrome approximately 2 weeks after the addition of venlafaxine. The medications were discontinued and the patient was given cyproheptadine for suspected serotonin syndrome, whereupon symptoms promptly resolved. A second episode occurred when dexamphetamine was subsequently resumed and citalopram added. The patient improved following cessation of citalopram on his own, and residual symptoms were successfully treated with cyproheptadine.
MANAGEMENT: In general, amphetamines and other sympathomimetic appetite suppressants should not be combined with selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs). Close monitoring for enhanced sympathomimetic effects and possible serotonin syndrome is recommended if these agents must be used together. Symptoms of the serotonin syndrome may include mental status changes such as irritability, altered consciousness, confusion, hallucinations, and coma; autonomic dysfunction such as tachycardia, hyperthermia, diaphoresis, shivering, blood pressure lability, and mydriasis; neuromuscular abnormalities such as hyperreflexia, myoclonus, tremor, rigidity, and ataxia; and gastrointestinal symptoms such as abdominal cramping, nausea, vomiting, and diarrhea.

Drug and Food Interactions
Moderate
Sertraline
+ Food
The following applies to the ingredients: Sertraline
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.

Moderate
Vyvanse
+ Food
The following applies to the ingredients: Lisdexamfetamine (found in Vyvanse)
GENERALLY AVOID: Alcohol may potentiate the cardiovascular effects of amphetamines. The exact mechanism of interaction is unknown. In one study, concurrent administration of methamphetamine (30 mg intravenously) and ethanol (1 gm/kg orally over 30 minutes) increased heart rate by 24 beats/minute compared to methamphetamine alone. This increases cardiac work and myocardial oxygen consumption, which may lead to more adverse cardiovascular effects than either agent alone. Subjective effects of ethanol were diminished in the eight study subjects, but those of methamphetamine were not affected. The pharmacokinetics of methamphetamine were also unaffected except for a decrease in the apparent volume of distribution at steady state. The interaction was suspected in a case report of a 20-year-old male who experienced retrosternal chest pain shortly after drinking alcohol and taking a double dose of his amphetamine/dextroamphetamine medication (Adderall 15 mg X 2) to stay alert. The patient had no family history of cardiovascular diseases, and his past medical history was remarkable only for ADHD. Prior to the episode, the patient had not taken his medication for weeks and had been drinking whiskey the previous three nights before going to bed. The patient was diagnosed with myocardial infarction likely secondary to amphetamine-induced coronary vasospasm.
MANAGEMENT: Concomitant use of amphetamines and alcohol should be avoided if possible, especially in patients with a history of heart disease.

Drug and Pregnancy Interactions
Major
Sertraline
+ Pregnancy
The following applies to the ingredients: Sertraline
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.

Major
Vyvanse
+ Pregnancy
The following applies to the ingredients: Lisdexamfetamine (found in Vyvanse)
Benefit should outweigh risk.
AU TGA pregnancy category: B3
US FDA pregnancy category: C
Comments:
-The active metabolite of this drug, dexamphetamine, crosses the placenta.
-Premature delivery, low birth weight, and other adverse pregnancy outcomes have been seen in infants born to mothers dependent on amphetamines.
-Monitor infants born to mothers taking amphetamines for symptoms of withdrawal such as feeding difficulties, irritability, agitation, and excessive drowsiness.
There are no controlled data of this drug in human pregnancy, but there are some available data for amphetamines in pregnant women. Two case control studies of over a thousand patients exposed to amphetamines at different gestational ages did not show an increase in congenital abnormalities. Additionally, animal studies have revealed no effects on embryofetal morphological development and survival, nor on fertility.
AU TGA pregnancy category B3: 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 have shown evidence of an increased occurrence of fetal damage, the significance of which is considered uncertain in humans.
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.

Drug and Breastfeeding Interactions
Major
Sertraline
+ Breastfeeding
The following applies to the ingredients: Sertraline
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.

Vyvanse
+ Breastfeeding
The following applies to the ingredients: Lisdexamfetamine (found in Vyvanse)
Use should be avoided during breastfeeding.
Excreted into human milk: Yes
Comments:
-This drug is a prodrug of dextroamphetamine. The effect of dextroamphetamine in milk on the neurological development of a breastfed infant has not been well studied.
-Large dosages of this drug might interfere with milk production, especially in women whose lactation is not well established.
-Blood levels of dextroamphetamine in 3 breastfed infants were up to 14% of the maternal plasma level.
-Four breastfed infants whose mothers took an average dose of 18 mg/day of dextroamphetamine had no adverse effects and showed normal progress with weights between the 10th and 75th percentiles.
-In a study of 20 postpartum women, dextroamphetamine reduced serum prolactin by 25% to 32% (7.5 mg IV dose) and 30% to 37% (15 mg IV dose). Another study showed a 20 mg oral dose produced a sustained suppression of serum prolactin by 40%.
