Precautions while taking Rifampin (Rifadin)Rifampin can cause serious liver problems, especially if you are also taking pyrazinamide (PZA). Make sure you understand the risks for liver problems and how to identify the symptoms. If you have any questions, talk with your prescriber or other health care provider. Visit your prescriber or health care professional for regular checks and report any serious side effects promptly.
Keep taking your rifampin even if you feel better. You may need to take this medicine for an extended period of time for a complete cure.
Avoid alcoholic drinks while you are taking rifampin. Drinking alcohol during treatment with rifampin increases the risk of serious liver problems.
Birth control pills (contraceptive pills) may not work properly while you are taking this medicine. Use a different method of birth control while you are taking rifampin.
This medicine can color your urine, feces (stool), perspiration (sweat), tears, sputum, skin or saliva reddish-orange to reddish-brown. This color can last for as long as you take rifampin and is not a cause for alarm. Talk to your prescriber or health care professional about it if it concerns you. However, this color in tears may permanently stain soft contact lenses. It is better not to wear soft contact lenses while you are taking rifampin.
If you are going to have surgery, tell your prescriber or health care professional that you are taking rifampin.
