Norinyl Drug Interactions

Modafinil (Provigil)
Modafinil can make Norinyl less effective, increasing your risk of pregnancy. Talk with your healthcare provider, as you may need to use a backup method of contraception.
 
Numerous Seizure Medications
Some seizure medications may cause your body to metabolize the hormones in Norinyl too quickly, increasing your risk of pregnancy. Ask your healthcare provider if you should use a different method of contraception while taking a seizure medication.
 
Protease Inhibitors
Using Norinyl together with a protease inhibitor may increase your risk of pregnancy and can make the protease inhibitor less effective. Talk with your healthcare provider before using Norinyl with a protease inhibitor.
 
Selegiline (Eldepryl, Emsam, Zelapar)
The hormones in Norinyl may increase the level of selegiline in your blood, increasing your risk of side effects. Your healthcare provider may need to lower your selegiline dosage or may recommend an alternate form of contraception.
 
Some Antibiotics
There have been reports of accidental pregnancy occurring in women taking birth control pills together with certain antibiotics. However, the significance of this interaction is still uncertain. Some antibiotics are more likely to cause problems than others. Any time you take an antibiotic, make sure to ask your healthcare provider if you need to use a backup method of contraception.
 
St. John's Wort
St. John's wort (a commonly used herbal supplement) may decrease the effectiveness of Norinyl, increasing the chance of pregnancy. In general, you should not take St. John's wort while using Norinyl.
