Drug Interactions

Moderate
Zoloft + Lamictal

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

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
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.

Moderate
Lamictal + Food

The following applies to the ingredients: Lamotrigine (found in Lamictal)

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: 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.

The following applies to the ingredients: Lamotrigine (found in Lamictal)

Benefit should outweigh risk

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

Risk Summary: Several prospective pregnancy exposure registries and epidemiological studies have not detected an increased frequency of major congenital malformations or a consistent pattern of malformations among women exposed to lamotrigine compared with the general population; animal studies have shown developmental toxicities at doses administered clinically.

Comments:
-Women with epilepsy who are planning to become pregnant should receive pre-pregnancy counseling; folate supplementation should be considered before conception and for the first 12 weeks of pregnancy.
-Abrupt discontinuation of anti-epileptic therapy during pregnancy is not advised as this may lead to breakthrough seizures in mother and fetus.
-Physiologic changes during pregnancy may affect drug concentrations and/or therapeutic effect; dose adjustments may be necessary to maintain clinical response.
-Women should be advised to notify their healthcare provider if they plan to start or stop oral contraceptive use or other female hormonal preparations as this may significantly affect lamotrigine drug concentrations.
-A pregnancy registry is available to provide information on the effects of in utero exposure; pregnant patients should be encouraged to enroll: North American AED Pregnancy Registry: US toll free number: 1-888-233-2334; Website: http://www.aedpregnancyregistry.org/

Animal studies have shown developmental toxicity at doses estimated to be lower than those used clinically. Pregnant rats administered 3 doses (5, 10 or 20 mg/kg) during the latter part of gestation had increased offspring mortality (including stillbirths) at all doses. The lowest effect dose for peri/postnatal developmental toxicity was less than the human dose of 400 mg/day on mg/m2 basis. Maternal toxicity was observed at the 2 highest doses. Studies in rats have shown a decrease in folic acid during pregnancy, and since this drug is a weak inhibitor of dihydrofolate reductase, there is a theoretical risk of malformation due to folate deficiency. Anti-epileptic drugs should generally be continued during pregnancy with the goal of monotherapy at the lowest effective dose, however, the risk to the mother and fetus of uncontrolled epilepsy should be considered when deciding on treatment options. Data from several international pregnancy registries have not shown an increased risk for malformations overall. The frequency of major congenital malformations was similar to estimates from the general population. The North American Antiepileptic Drug Pregnancy (NAAED) Registry has reported an increased risk of isolated oral clefts, although this finding has not been observed in other large international pregnancy registries. Several meta-analyses have not reported an increased risk of major congenital malformations following lamotrigine exposure in pregnancy compared with healthy and disease-matched controls. No patterns of specific malformation types were observed. As with other antiepileptic drugs, decreased lamotrigine concentrations have been reported during pregnancy with a return to pre-pregnancy concentrations after delivery. Appropriate clinical management should include monitoring drug concentrations and adjusting doses as indicated. There are no adequate and well-controlled studies in pregnant women.

AU TGA pregnancy category D: Drugs which have caused, are suspected to have caused or may be expected to cause, an increased incidence of human fetal malformations or irreversible damage. These drugs may also have adverse pharmacological effects. 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: 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.

The following applies to the ingredients: Lamotrigine (found in Lamictal)

Benefit should outweigh risk

Excreted into human milk: Yes

Comments:
-Adverse reactions have occasionally been reported in breastfed babies, but long-term exposure does not appear to affect infant growth and development.
-Breastfed infants should be carefully monitored for side effects; serum levels may be measured to rule out toxicity.
-If infant rash occurs, breastfeeding should be discontinued until cause can be established.

Drug concentrations in human milk may be as high as 50% of the maternal serum levels. Neonates are at risk for high plasma levels due to plasma protein binding being relatively low and decreased ability to clear drug (immaturity of glucuronidation capacity). Additionally, similar to other antiepileptic drugs, the maternal dose should generally be reduced after delivery to the pre-pregnancy dosage, and failure to reduce dose may lead to higher milk concentrations. Apnea, rash, drowsiness, and poor sucking have been reported in breastfed infants. If an adverse event occurs, a serum level can be measured to rule out toxicity. Consider monitoring platelet counts and liver function. Breastfeeding should be discontinued in infants with lamotrigine toxicity
