5 Interactions found for:

The following applies to the ingredients: Omeprazole

This drug should be used during pregnancy only if the benefit outweighs the risk to the fetus.

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

Risk Summary: Epidemiologic studies have demonstrated that major malformative risks with use in pregnant patients are unlikely.

Comment: Some experts recommend that use is considered acceptable.

Animal models have revealed evidence of dose-related increases in embryolethality, fetal resorptions, and pregnancy disruptions when animal models were given this drug during organogenesis. Major fetal malformations were not frequently observed in animal models. Embryofetal and postnatal developmental toxicities were observed in offspring of parents given at least 3.4 times an oral human dose of 40 mg.

Embryofetal toxicity is associated with maternally toxic doses given throughout gestation as well as in high doses given to males prior to mating.

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: Tirzepatide (found in Mounjaro)

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.

The following applies to the ingredients: Omeprazole

Use is not recommended.

Excreted into human milk: Yes

Comments:
-This drug is associated with tumorigenicity in animal models, and may suppress gastric acid secretion in the nursing infant.
-The American Academy of Pediatrics state that this drug should be avoided until additional studies can confirm the safe use of this drug during breastfeeding.

In animal models, decreased postpartum offspring growth rates were observed when this drug was administered during late gestation and throughout lactation at oral doses of at least 138 mg/kg/day and IV doses of 3.2 mg/kg/day.

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

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.
