Some people can experience an improvement in their anxiety symptoms just a few weeks after they start taking it regularly. But the bigger benefit of it can be felt around the 6th and 8th week of treatment. 

Although Prozac is an antidepressant, it has often been used to treat anxiety as well. Because it influences the serotonin level, it improves the person’s mood, helps them regulate their emotions, and improves their appetite and sleep patterns. When a person feels this improvement in their life, they can react differently, less anxious. 

Prozac is usually used to treat anxiety because it is a safe medication to be taken for a prolonged period and because its side effects are usually less serious. Not only that, when patients with anxiety take Prozac and also go to therapy, they can become able to relax and have a higher quality of life.

The dosage that is often used for people treating anxiety can differ. A person that is treating Obsessive-Compulsive disorder usually starts with 20mg, and it can be increased to another 20mg each month, if it is necessary, until the maximum dosage of 80mg.
