Can you feel Prozac after 1 day?

Prozac, a trade name for fluoxetine is an SSRI (selective serotonin reuptake inhibitor) antidepressant. Its benefits, among many is that it affects chemicals in the brain which may become unbalanced and cause depression, panic, anxiety, or obsessive-compulsive symptoms.

Also, Prozac is used to treat major depressive disorders such as bulimia nervosa- an eating disorder, OCD (obsessive-compulsive disorder), panic disorders, and PMDD (premenstrual dysphoric disorder).

Whilst its usage typically manifests itself after about a fortnight, (two weeks), there are side-affects which can include nervousness, loss of sleep, slight anxiety, and very rarely nausea. Generally, after a brief period of endurance, these side-affects dissipate after a brief period of usage. As for Prozac assisting with matters of diet, (what it was originally created for), or anxieties, it is highly doubtful that one might feel any change in these conditions within 24 hours. Mostly, the initial side-effect is feeling somewhat jittery or anxious. It may be that the doses you are taking are too high initially.

Additionally, it is advisable to check your blood pressure. If you are obese, or facing other challenges which affect blood pressure, it may be best to consider changing to a similar SSRI such as Citalopram.
