You can get tablets or capsules prescribed in 75 and 37.5 mg doses and decrease by breaking tablets or reducing by 37.5 mg increments with capsules. I am currently weaning off 150 mg Effexor that I have been taking for at least 20 years. My doctor has prescribed Prozac 10 mg to ease withdrawal symptoms. I have finished my first week reducing by 37.5 — so I am currently on 112.5 Effexor along w 10 mg Prozac. So far my symptoms are a little nausea and insomnia.
