7 Interactions found for:
Drug Interactions
Moderate
Lamictal
+ Lexapro
The following applies to the ingredients: Lamotrigine (found in Lamictal) and Escitalopram (found in Lexapro)
Treatment with escitalopram may occasionally cause blood sodium levels to get too low, a condition known as hyponatremia, and using it with some anticonvulsants can increase that risk. In addition, escitalopram can cause seizures in susceptible patients, which may reduce the effectiveness of medications that are used to control seizures such as lamoTRIgine. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. You should seek medical attention if you experience nausea, vomiting, headache, lethargy, irritability, difficulty concentrating, memory impairment, confusion, muscle spasm, weakness or unsteadiness, as these may be symptoms of hyponatremia. More severe cases may lead to hallucination, fainting, seizure, coma, and even death. Also let your doctor know if you develop seizures or experience an increase in seizures during treatment with escitalopram. Additionally, because these medications may cause dizziness, drowsiness, and impairment in judgment, reaction speed and motor coordination, you should avoid driving or operating hazardous machinery until you know how they affect you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Drug and Food Interactions
Moderate
Lamictal
+ Food
The following applies to the ingredients: Lamotrigine (found in Lamictal)
Alcohol can increase the nervous system side effects of lamoTRIgine such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with lamoTRIgine. Do not use more than the recommended dose of lamoTRIgine, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
Moderate
Lexapro
+ Food
The following applies to the ingredients: Escitalopram (found in Lexapro)
Alcohol can increase the nervous system side effects of escitalopram such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with escitalopram. Do not use more than the recommended dose of escitalopram, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
Drug and Pregnancy Interactions
Major
Lexapro
+ Pregnancy
The following applies to the ingredients: Escitalopram (found in Lexapro)
Professional Content
This drug should be used during pregnancy only if the benefit outweighs the risk to the fetus.
AU TGA Pregnancy Category: C
US FDA Pregnancy Category: C
Comments:
-Newborns should be monitored if the maternal use of this drug continues into the later stages of pregnancy, particularly, the third trimester.
-Abrupt discontinuation should be avoided during pregnancy.
Animal studies have revealed evidence of embryotoxicity (e.g., reduced fetal weight and reversible delay of ossification), offspring mortality, and delayed growth. Animal studies with racemic citalopram have revealed evidence of teratogenicity at doses greater than human therapeutic doses. There are no controlled data in human pregnancy. Human spontaneous abortion has been reported with racemic citalopram.
Neonates exposed to SSRIs late in the third trimester have uncommonly reported clinical findings including respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, 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, or possibly a drug discontinuation syndrome; in some cases, the clinical picture is consistent with serotonin syndrome.
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 from animal studies has shown that escitalopram may affect sperm quality. Human case reports from some SSRIs have shown this effect to be reversible. As yet, the impact of this on human fertility has not been observed.
To monitor the outcomes of pregnant women exposed to antidepressants, a National Pregnancy Registry for Antidepressants has been established. Physicians are encouraged to register patients and pregnant women are encouraged to register themselves. 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 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.

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
Minor
Lamictal
+ Breastfeeding
The following applies to the ingredients: Lamotrigine (found in Lamictal)
Professional Content
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

Lexapro
+ Breastfeeding
The following applies to the ingredients: Escitalopram (found in Lexapro)
Professional Content
Use with caution; the benefit to the mother should outweigh the risk to the infant.
Excreted into human milk: Yes
Comments:
-Breastfed infants should be monitored for drowsiness and decreased feeding.
-Mothers taking an SSRI during pregnancy and postpartum may have difficulty breastfeeding and may require additional breastfeeding support.
Escitalopram is not expected to cause adverse effects in breastfed infants, particularly in infants over 2 months of age. One case of necrotizing enterocolitis has been reported in a breastfed newborn whose mother was taking escitalopram during pregnancy and lactation; however, causality was not established.
Maternal doses of escitalopram up to 20 mg per day lead to low levels in milk, approximately 3.9% and 1.7% of the maternal weight-adjusted dose of escitalopram and desmethylcitalopram, respectively. Limited data suggest that escitalopram is preferable to racemic citalopram during breastfeeding due to lower dosage and milk levels, and general lack of side effects in breastfed infants.
