It seems like a quick bump up, but trust your doctor. Usually, there is more time inbetween dosage increases, but everyone is different, and your dr. knows you the best. The typical range of Prozac for an adult with OCD is about 80 mg, anywhere from 60 to 100 plus.
How long does it take to kick in?
Would it take more then a week
it can take up to 12 weeks to feel the full effect of anti depressants.
although 3 to 4 weeks is more common. You may see a difference in as little as a week.
I was in the 4 week range myself.
