Drug Interactions With Zarah

Heparin, antibiotics, and ibuprofen are just a few of the drugs that can react with Zarah. Since these interactions can increase your risk of high potassium levels and other problems, it's important to tell your healthcare provider about all of your current medications before using Zarah. This will help ensure that this is the right birth control pill for you.
