Drug interference with depo-provera injection

Patient: Hi there, I have asthma and have been prescribed Spiropent (Clenbuterol) to make my breathing easier. I was just wondering if this will affect my birth control. I am currently on the Depo Provera contraceptive injection.

Doctor: Clenbuterol will not reduce the effectiveness of Depo Provera contraceptive injection. I hope this helps, take care.
