Drug and Food Interactions

Moderate
Gabapentin + Food

The following applies to the ingredients: Gabapentin

Alcohol can increase the nervous system side effects of gabapentin 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 gabapentin. Do not use more than the recommended dose of gabapentin, 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
Mounjaro + Food

The following applies to the ingredients: Tirzepatide (found in Mounjaro)

Tirzepatide may affect the absorption of other medications that you take by mouth. In some cases, this may affect how well and/or how fast those medications work, or it may make no difference. Talk to a healthcare provider if you have any questions or concerns, and contact your doctor if your symptoms worsen or your condition changes. 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 Pregnancy Interactions

The following applies to the ingredients: Gabapentin

Professional Content

Benefits should clearly outweigh risks

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

Risk Summary: There are no data on the developmental risks associated with use of this drug in pregnant women; in animal studies, developmental toxicity was observed at doses estimated to be similar or lower than those used clinically.

Comments:
-The risk of having a child with a congenital defect as a result of antiepileptic medication is far outweighed by the dangers to the mother and fetus of uncontrolled epilepsy; folic acid supplementation (5 mg) should be started 4 weeks prior to and continued for 12 weeks after conception.
-Women of childbearing potential should receive counseling on the risk of fetal abnormalities with use of antiepileptic drugs (AEDs) during pregnancy; AEDs should generally be continued during pregnancy utilizing monotherapy at the lowest effective dose as this has been shown to minimize risks of fetal abnormalities compared to combination AED therapy.
-A pregnancy exposure registry is available.

Animal studies have revealed evidence of developmental toxicity (increased fetal skeletal and visceral abnormalities, and increased embryofetal mortality) when administered at doses similar to, or lower than expected clinical doses. In rats, an increased incidence of hydroureter and/or hydronephrosis have been observed in offspring at all doses, the lowest dose being similar to the maximum recommended human dose on a mg/m2 basis. This drug crosses the human placenta. From the limited amount of data in human pregnancy, it is not possible to inform an associated increased risk of congenital malformations because epilepsy itself and the presence of concomitant antiepileptic medicinal products have their own risks. There are no controlled data in human pregnancy.

To provide information regarding the effects of in utero exposure to this drug, pregnant patients should be encouraged to 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. 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.

Professional Content

This drug should be used during pregnancy only if the benefit outweighs the risk to the fetus.
According to some authorities: Use of this drug is not recommended during pregnancy or in women of childbearing potential not using contraception.

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

Risk summary: Insufficient data available on use of this drug in pregnant women to inform a drug-related risk; based on animal data, this drug may cause fetal harm.

Comments:
-There are risks to mother and fetus associated with poorly controlled diabetes in pregnancy.
-Use of this drug may reduce the efficacy of oral hormonal contraceptives due to delayed gastric emptying; this delay is largest after the first dose and diminishes over time. Patients using oral hormonal contraceptives should be advised to switch to a non-oral contraceptive method or add a barrier method of contraception for 4 weeks after initiation and for 4 weeks after each dose escalation with this drug.

Animal studies have revealed evidence of teratogenicity, fetotoxicity, and abortion when this drug was administered in pregnant animals during organogenesis at clinically relevant exposures based on AUC. These adverse embryo-fetal effects in animals coincided with pharmacological effects on maternal weight and food consumption. Animal studies with this drug did not indicate direct harmful effects with respect to fertility. There are no controlled data in human pregnancy.

Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, preeclampsia, spontaneous abortions, preterm delivery, and delivery complications; poorly controlled diabetes increase the fetal risk for major birth defects, stillbirth, and macrosomia-related morbidity.

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: Gabapentin

Professional Content

Benefits should clearly outweigh risks

Excreted into human milk: Yes

Comments:
-Breastfed infants should be monitored for drowsiness, adequate weight gain, and developmental milestones, especially when used in combination with other anticonvulsant or psychotropic drugs and in younger, exclusively breastfed infants.
-Some authorities suggest discontinuing nursing or discontinuing use of this drug while breastfeeding due to the potential for serious adverse reactions in the breastfed infant.

With maternal doses up to 2.1 g/day, estimated doses for fully breastfed infants are 0.2 to 1.3 mg/kg/day (equivalent to 1.3 to 3.8% of the maternal weight-adjusted dose). An expert panel has deemed this drug is an acceptable choice for refractory restless leg syndrome during lactation. Until more data becomes available, the developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for this drug and any potential adverse effects on the breastfed infant from this drug or from the underlying maternal condition.

The following applies to the ingredients: Tirzepatide (found in Mounjaro)

Professional Content

Benefit should outweigh risk.
According to some authorities: 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: Unknown
Excreted into animal milk: Unknown

Comments:
-Developmental and health benefits of breastfeeding should be considered as well as the mother's clinical need for this drug.
-The effects in the nursing infant are unknown; potential side effects in the breastfed child due to this drug or the mother's underlying condition should be considered.
-The quantity of this drug in breast milk or absorbed by the breastfed child is expected to be low due to the large molecular weight of this drug and its probable partial destruction within the infant gastrointestinal tract.
