Nor-QD Interactions Explained
The following sections explain in detail the potentially negative interactions that can occur when
Nor-QD is combined with any of the drugs listed above. If you are unsure about any particular interaction, it is a good idea to use backup birth control until you can speak with your healthcare provider.
Aminoglutethimide (Cytadren)
Combining Nor-QD with aminoglutethimide may increase your risk of unintentional pregnancy. Talk with your healthcare provider before using these medications together. You may need to use a backup method of contraception, such as condoms.
Antibiotics
There have been reports of unintentional pregnancy occurring in women taking
birth control pills with certain antibiotics. However, it is still uncertain how significant this interaction may be, since many of these cases may have been simply coincidence. Some antibiotics are more likely to cause problems than others. Ask your healthcare provider if you need a backup method of contraception any time you take an antibiotic.
Aprepitant (Emend)
Aprepitant may make Nor-QD 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.
Barbiturates
Barbiturates may cause your body to metabolize the hormones in Nor-QD too quickly, possibly increasing your risk of pregnancy. Ask your healthcare provider if you should use a different method of contraception while taking a barbiturate.
Bosentan (Tracleer)
Bosentan may make Nor-QD 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.
