Drug Interactions

Moderate
Cymbalta + Lyrica

The following applies to the ingredients: Duloxetine (found in Cymbalta) and Pregabalin (found in Lyrica)

MONITOR: The efficacy of anticonvulsants may be diminished during coadministration with selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitor (SNRIs). Antidepressants including SSRIs and SNRIs can reduce seizure threshold. In clinical trials, convulsions have typically been reported in 0.1% to 0.3% of patients receiving SSRIs for major depressive disorders. There have been rare reports of prolonged seizures in patients on fluoxetine receiving electroconvulsive therapy (ECT).

MONITOR: Coadministration of SSRIs or SNRIs may potentiate the central nervous system (CNS) adverse effects of anticonvulsants such as somnolence and cognitive and psychomotor impairment.

MONITOR: Coadministration of SSRIs or SNRIs with some anticonvulsants, particularly carbamazepine, eslicarbazepine, oxcarbazepine and valproic acid, may increase the risk of hyponatremia. Treatment with SSRIs or SNRIs has been associated with hyponatremia, which may be due to the syndrome of inappropriate antidiuretic hormone secretion (SIADH) in many cases. While generally reversible following discontinuation of SSRI/SNRI treatment, cases with serum sodium lower than 110 mmol/L have been reported. Hyponatremia and SIADH may also result from treatment with some anticonvulsants. The risk appears to be dose-related, and elderly patients and patients who are volume depleted (e.g., diuretic use) may be at greater risk.

MANAGEMENT: SSRIs and SNRIs should be avoided in patients with unstable epilepsy, and used cautiously in patients with epilepsy controlled with anticonvulsant medications. Treatment with SSRIs and SNRIs should be discontinued if seizures develop or seizure frequency increases. Patients receiving SSRIs or SNRIs with anticonvulsants, particularly carbamazepine, eslicarbazepine, oxcarbazepine and/or valproic acid, should also have serum sodium levels measured regularly and monitored for development of hyponatremia, particularly when higher dosages of these medications are used. Signs and symptoms of hyponatremia include nausea, vomiting, headache, difficulty concentrating, memory impairment, confusion, malaise, lethargy, muscle weakness or spasms, and unsteadiness. In more severe and/or acute cases, hallucination, syncope, seizure, coma, respiratory arrest, and death may occur. Discontinuation of SSRIs and SNRIs should be considered in patients who develop symptomatic hyponatremia, and appropriate medical intervention instituted. All patients receiving concomitant therapy with SSRIs or SNRIs and anticonvulsants should be counseled against driving, operating machinery, or engaging in potentially hazardous activities requiring mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Drug and Food Interactions

Moderate
Cymbalta + Food

The following applies to the ingredients: Duloxetine (found in Cymbalta)

GENERALLY AVOID: Use of duloxetine in conjunction with chronic alcohol consumption may potentiate the risk of liver injury. Duloxetine alone can increase serum transaminase levels. In clinical trials, 0.3% of patients discontinued duloxetine due to liver transaminase elevations. The median time to detection was about two months. Three duloxetine-treated patients had liver injury as manifested by transaminase and bilirubin elevations, with evidence of obstruction. Substantial intercurrent ethanol use was present in each of these cases, which may have contributed to the abnormalities observed. Duloxetine does not appear to enhance the central nervous system effects of alcohol. When duloxetine and ethanol were administered several hours apart so that peak concentrations of each would coincide, duloxetine did not increase the impairment of mental and motor skills caused by alcohol.

MANAGEMENT: Due to the risk of liver injury, patients prescribed duloxetine should be counseled to avoid excessive use of alcohol. Duloxetine should generally not be prescribed to patients with substantial alcohol use.

Moderate
Lyrica + Food

The following applies to the ingredients: Pregabalin (found in Lyrica)

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and 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 these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Drug and Pregnancy Interactions

The following applies to the ingredients: Duloxetine (found in Cymbalta)

This drug should not be used during pregnancy unless the benefit outweighs the risk to the fetus.

AU TGA pregnancy category: B3
US FDA pregnancy category: Not assigned.

Risk summary: Observational study data have not produced clear drug-associated risks regarding adverse events or major birth defects.

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.
-Women who discontinued antidepressant use during pregnancy were more likely to experience a relapse of major depression than women who continued antidepressant use.

Animal studies have revealed increased perinatal toxicity and fetotoxicity at doses potentially correlated with maternal toxicity. There are no controlled data in human pregnancy.

Some neonates exposed to SNRIs (Serotonin and Norepinephrine Reuptake Inhibitors), or SSRIs (Selective Serotonin Reuptake Inhibitors) late in the third trimester had clinical findings including respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying. This clinical picture is consistent with either direct toxic effect of SSRIs and SNRIs, drug discontinuation syndrome, or serotonin syndrome.

A less than 2-fold increase in postpartum hemorrhage was determined by observational data in patients exposed to the drug within 1 month before birth.

A study of women with a history of major depression who were euthymic at the beginning of pregnancy, showed women who discontinued antidepressant medication during pregnancy were more likely to experience a relapse of major depression than women who continued antidepressant medication.

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/

Healthcare providers are encouraged to register patients receiving Cymbalta by calling the Cymbalta Pregnancy Registry at 1-866-814-6975 or by visiting www.cymbaltapregnancyregistry.com.

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 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.

The following applies to the ingredients: Pregabalin (found in Lyrica)

This drug should only be given during pregnancy when there are no alternatives and benefit outweighs risk

AU TGA pregnancy category: B3
US FDA pregnancy category: Not assigned

Risk Summary: There are no adequate and well-controlled studies in pregnant women; animal reproduction studies have shown increased incidences of fetal structural abnormalities and other manifestations of developmental toxicity.

Comment:
-Patients should be advised of the potential risk to a fetus.
-Women of childbearing potential should be encouraged to use reliable contraception during treatment.
-Physicians should encourage pregnant patients to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry; toll free 1-888-233-2334 or http://www.aedpregnancyregistry.org/

Increased incidences of fetal structural abnormalities and other manifestations of developmental toxicity including skeletal malformations, retarded ossification, and decreased fetal body weight have been observed in rat and rabbit offspring receiving this drug at 18 times or greater the maximum recommended dose during organogenesis. Lethality, growth retardation, and nervous and reproductive system functional impairment have been observed in rat offspring receiving this drug during gestation and lactation. Rat offspring tested as adults, showed neurobehavioral abnormalities (decreased auditory startle responding). There are no controlled data in human pregnancy.

A clinical trial in healthy male subjects found that 3 months of taking this drug at 600 mg/day did not effect sperm motility. Adverse reproductive and developmental effects have been observed in male rats.

To provide information regarding the effects of in utero exposure to this drug, physicians are advised to recommend that pregnant patients enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry. This can be done by calling the toll free number 1-888-233-2334, and must be done by patients themselves. Information on the registry can also be found at the website http://www.aedpregnancyregistry.org/.

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.

Drug and Breastfeeding Interactions

The following applies to the ingredients: Duloxetine (found in Cymbalta)

Use is not recommended and a decision should be made to discontinue breastfeeding or discontinue the drug, taking into account the importance of the drug to the mother.

Excreted into human milk: Yes

Comments:
-Some experts state that a more thoroughly studied alternative agent (e.g., nortriptyline, paroxetine, sertraline) may be preferred while breastfeeding premature or neonates.
-The American Academy of Pediatrics classifies other antidepressants as agents for which the effect on nursing infants is unknown but may be of concern.
-Exposed infants should be monitored for developmental milestones, feeding, sedation, weight gain, especially in younger infants who are exclusively breastfed and/or when breastfed infants are exposed to multiple antipsychotropic agents.

The estimated neonatal dose is approximately 0.1% to 0.3% of the maternal dose.

Breastfeeding is not recommended

Excreted into human milk: Yes

Comment:
-Because of the potential risk of tumorigenicity, breastfeeding is not recommended during treatment.

Limited data have shown the estimated average daily infant dose expected from breast milk is about 7% of the maternal weight adjusted dose. An unexpectedly high incidence of hemangiosarcoma was observed in standard preclinical in vivo lifetime carcinogenicity studies in 2 different strains of mice. The clinical significance of this finding is unknown.
