NuvaRing Interactions Explained
The following sections explain in detail the potentially negative interactions that can occur when
NuvaRing is combined with any of the drugs listed above.
Aminoglutethimide (Cytadren)
Aminoglutethimide may make NuvaRing less effective, possibly increasing your risk of pregnancy. Talk with your healthcare provider before using these medications together. You may need to use a backup method of contraception (such as condoms).

Barbiturates
Barbiturates may cause your body to metabolize the hormones in NuvaRing too quickly, increasing your risk of pregnancy. Ask your healthcare provider if you should use a different method of contraception while taking a barbiturate.
Certain Seizure Medications
Some
seizure medications may cause your body to metabolize the hormones in NuvaRing 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.
Cyclosporine (Gengraf, Neoral, Sandimmune)
NuvaRing may increase the level of cyclosporine in your blood, increasing the chance of side effects of cyclosporine. Talk with your healthcare provider before taking these medications together. Your cyclosporine dose may need to be reduced, or you may need to switch to a different method of contraception.
