I'm sure it's fine, Mseerob, and a lot better than smoking it. That's an antibiotic for the infection you have (Sandoz is the name of the pharmaceutical company that manufactures the one you were prescribed), and it's unlikely that cannabis would interact negatively with an antibiotic. In some ways, it might even enhance its effects because the cannabinoids alone have nice anti-inflammatory effects and are even thought by some to have antibiotic properties.

It's true that smoking cannabis aggravates irritation and pulmonary congestion and can make people more prone to infections. Lots of folks don't believe that, but it does and that's been proven repeatedly in tests. It's not the THC or cannabinoids that causes problems. It's all the other crap in the smoke. Hope you feel better soon!
