How Long Does Prozac Take to Work?

Prozac (fluoxetine) is one of the most well-known antidepressants, regularly prescribed for depression, OCD, and various anxiety disorders. If you've just started Prozac, you're likely wondering when you'll begin feeling better. While some patients notice changes within 2 weeks, it typically takes 4-8 weeks to experience the full benefits.

Prozac Timeline by Condition

How quickly Prozac works depends partly on what you're treating:

• Major Depression: 4-8 weeks for full effect, though some improvement may be noticed in 2 weeks
• OCD: 4-6 weeks typically, but may take up to 12 weeks. OCD often requires higher doses
• Bulimia Nervosa: Some relief may be noticed within 3 weeks

At Next Step Psychiatry, we typically start patients on a low dose and adjust based on response. Dr. Aneel Ursani and Fathima Chowdhury PA-C carefully monitor progress to optimize your treatment.

8 Signs Prozac Is Working

Here's how our Gwinnett County patients know their medication is helping:

1. You find yourself enjoying life more fully
2. Feelings of depression or anxiety lessen
3. You have more energy throughout the day
4. Sleep quality improves
5. Appetite becomes more regular
6. Daily activities feel more manageable
7. You're less preoccupied by symptoms
8. Reduced urges related to eating disorders (if applicable)

Common Side Effects

Another way you'll know Prozac is active in your system is through potential side effects:

• Nausea
• Drowsiness
• Dry mouth
• Sexual side effects

These typically improve within the first few weeks. If side effects are significant, contact our Lilburn office.

Best Time to Take Prozac

Prozac can interfere with sleep for some people, so many find it helpful to take it in the morning. However, if Prozac makes you drowsy, your provider might suggest taking it at night. The most important thing is consistency—take it at the same time each day.

What to Watch For

During the first three weeks, mild side effects are common but should improve. Contact your psychiatrist if you experience:

• Increased suicidal thoughts
• Severe mood swings
• Symptoms that worsen rather than improve

Never stop Prozac without guidance from your provider, as stopping suddenly can cause uncomfortable withdrawal symptoms.
