Drugs That React With Levonest
The following sections explain in detail the potentially negative interactions that can occur when Levonest is combined with any of the drugs listed above. It is important to note that if a backup method of contraception is necessary, it is sometimes advised to use the backup method for quite a while (often an entire cycle), depending on your particular situation.
Taking Levonest and aminoglutethimide together increases the risk of pregnancy. Do not use these medications together without checking with your healthcare provider first. 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 with certain antibiotics. It is still uncertain how significant the interaction between birth control pills and antibiotics may be. 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 may make Levonest 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. Aprepitant is commonly used by people undergoing chemotherapy, and it is usually very important for women having chemotherapy to avoid pregnancy.
Barbiturates may cause your body to metabolize the hormones in Levonest too quickly, increasing your risk of pregnancy. Ask your healthcare provider if you should use a different method of contraception while taking a barbiturate.
