I have tb and taking meds, is it safe for me to take other medicines? or can i also use birth control pills?

It is important you ask your pharmacist/doctor if you should have need to take other medication to let them know all medications you were already taking. If you are on rifampin which is often used with most TB medication regimen it tends to affect how other medications are processed in the body including birth control pills. It could lead to reduced effectiveness of birth control pills add condom.
