There are a number of precautions and warnings to be aware of before taking Sumycin. Some of these include:
- Sumycin may decrease the effectiveness of birth control pills. If you are using birth control pills, talk with your healthcare provider about other options for contraception.
- Sumycin is considered a pregnancy Category D medicine. This means that there is significant risk to an unborn baby if the drug is taken during pregnancy. If you are pregnant or thinking of becoming pregnant, talk with your healthcare provider before taking this medication.
- Skin reactions that resemble serious sunburns may occur if you are exposed to sunlight while taking the medicine. Try to avoid unnecessary sunlight exposure during treatment. If sunlight exposure is unavoidable, cover as much of your skin as possible by wearing long sleeves, long pants, and a hat -- and use a sunscreen with a rating of SPF 45 or higher.
