### Important Information for Women on Oral Contraceptives Using Mounjaro Many women who are taking oral contraceptives might not be aware that medications like Mounjaro, which are used for weight loss and blood sugar control, can interfere with the effectiveness of birth control pills. This interference can increase the risk of unintended pregnancy. #### How Mounjaro Works Mounjaro is part of a class of drugs called GLP-1 receptor agonists. These drugs help with weight loss and blood sugar control by delaying the time it takes for food to move from the stomach to the small intestine. This process, known as delayed gastric emptying, can affect how well birth control pills are absorbed in the body. #### Side Effects and Risks Common side effects of Mounjaro include nausea, vomiting, and diarrhea. These side effects can also impact the effectiveness of birth control pills. As the dosage of Mounjaro increases, these side effects become more common, further affecting the absorption of oral contraceptives. #### Recommendations for Women To avoid unintended pregnancy, women using Mounjaro should consider additional contraceptive methods. Using condoms or discussing other options like IUDs or implantable rods with their doctor can provide extra protection. It's also advisable to space out the timing of taking Mounjaro and birth control pills by at least one hour. #### Doctor's Advice Doctors recommend starting barrier contraception, such as condoms, four weeks before beginning Mounjaro and continuing to use them during any dose adjustments. This precaution helps ensure that the birth control pills remain effective. #### Conclusion Women on oral contraceptives should be aware of the potential risks associated with using Mounjaro. Consulting with healthcare providers and considering additional contraceptive methods can help prevent unintended pregnancies.
