Depends on the side effects, but as long as they weren't serious, then definitely. My wife has trouble taking birth control due to hormone imbalances, so we generally just rely on condoms. I'd prefer something a bit safer though (and would like to be able to enjoy sex without a condom too for that matter).
If you build a man a fire, he'll be warm for a day.
If you set a man on fire, he'll be warm for the rest of his life.
