More Details on Drug Interactions With ZarahThe following sections explain in detail the potentially negative interactions that can occur when Zarah is combined with any of the drugs listed above.
ACE Inhibitors and Angiotensin II Receptor Blockers (ARBs)
Combining Zarah with ACE inhibitors or ARBs can increase the risk of high potassium levels in your blood (hyperkalemia). Your healthcare provider should check your potassium levels regularly while you are using Zarah, particularly during the first cycle you use it.
Aminoglutethimide may make Zarah less effective, possibly increasing your risk of pregnancy. Talk with your healthcare provider before using these drugs together. You may need to use a backup method of contraception (such as condoms).
There have been reports of accidental pregnancy occurring in women taking birth control pills and certain antibiotics. However, it is still uncertain how significant this drug interaction may be. It is known that rifampin (Rifadin®) and minocycline (Minocin®) can make Zarah less effective. Ask your healthcare provider if you need a backup method of contraception any time you take an antibiotic.
Aprepitant may make Zarah less effective, perhaps increasing your chance of pregnancy. Talk with your healthcare provider before using these medications together. You may need to use a backup method of contraception.
Atorvastatin may increase the level of Zarah in your blood, which may increase your risk of Zarah side effects. Check with your healthcare provider before taking these medications together.
