Does phentermine decrease the effectiveness of prozac?
A doctor has provided 1 answer
Potentially interact: "Fluoxetine may increase the effects of phentermine, and side effects such as jitteriness, nervousness, anxiety, restlessness, and racing thoughts have been reported. Combining these medications can also increase the risk of a rare but serious condition called the serotonin syndrome". This is per the Drugs.Com drug interaction checker.
