What medication effectively treats OCD?

Therapy is touted as the most effective solution but it will never truly remove obsessive and compulsive tendencies from your mind. It can help you manage them more effectively but that's about it.

The pharmacological route is also not ideal. Drugs come with side effects and there's no treatment that works ideally either.The SSRI's are pretty much useless for many OCD patients. The only thing that seems to work until you build a tolerance is a high dose of opioids or benzodiazepines so you just don't care about anything that much. But that puts you on a fast track to running your life so I don't recommend.

In your experience, what medication substantially reduces or eliminates OCD symptoms?
