Before taking rifampin, tell your doctor if you are allergic to any drugs, or if you have liver disease or porphyria ( (a genetic enzyme disorder that causes symptoms affecting the skin or nervous system).
 | Take this medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Rifampin will not treat a viral infection such as the common cold or flu. |
 | Take the rifampin capsule on an empty stomach 1 hour before or 2 hours after a meal. |
 | Rifampin can make birth control pills less effective. Ask your doctor about using a non-hormone method of birth control (such as a condom, diaphragm, spermicide) to prevent pregnancy while taking rifampin. |
 | There are many other medicines that can interact with rifampin. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor. Keep a list with you of all the medicines you use and show this list to any doctor or other healthcare provider who treats you. |
Do not wear contact lenses while you are taking rifampin. This medicine may discolor your tears, which could permanently stain soft contact lenses.
