Is 90 mg of Prozac too high for a starting dosage?

I assume you are referring to Prozac Weekly, as this is the typical dose we prescribe for it. The weekly pill only comes in a 90 mg form that I am aware of, and it's usually started about a week after stopping regular Prozac (typically, the weekly form is not prescribed for acute treatment--just long-term treatment, although some physicians may start with it). As with any of the anti-depressants, the main thing we look for is an increase in suicidal thoughts and actions or worsening of the patient's depression. Make sure that if this is happening to immediately seek help. If you have questions about why you were started on the medication at the dose you were, talk to the physician who prescribed it. Hope this helps! Dr. B. REGULAR Prozac is (according to Nursing Drug Handbook) usually started at 20 mg. in the A.M., increased to twice a day, with the maximum being 80 mg./day. Always question your doctor and pharmacist, and ask your pharmacist for a print- out on Prozac. It has tons of information.
