- Less likely to make you sleepy compared to some other antidepressants, such as paroxetine (Paxil)
- Taken by mouth, typically once daily (IR capsules and liquid) or once weekly (DR capsules, for depression only)
- Can be taken with or without food

- Can interact with other medications, especially those affecting serotonin levels
- Can cause withdrawal symptoms if you suddenly stop taking it
Pharmacist tips for Fluoxetine (Prozac)
- You can take fluoxetine (Prozac) with or without food, but fluoxetine (Prozac) also commonly causes nausea, especially when starting the medication and with dose changes; taking it with food might help with these side effects.
- Don't change your dose or suddenly stop taking fluoxetine (Prozac) without talking to your provider first. Doing so can cause bothersome withdrawal symptoms like nausea, headache, and sleeping problems. Follow your psychiatrist's instructions to lower your dose slowly over a period of time to safely stop the medication.
- Fluoxetine (Prozac) can cause some people to feel less hungry. Make sure you're eating a healthy and well-balanced diet while taking fluoxetine (Prozac) to ensure you're getting enough nutrition.
- Although less likely than other SSRIs, fluoxetine (Prozac) can cause sexual side effects, such as ejaculation problems in males, low sex drive, and erectile dysfunction.
- Fluoxetine (Prozac) can make you sleepy and dizzy. Don't drive or do anything requiring concentration until you know how this medication affects you.
- Avoid drinking alcohol while taking fluoxetine (Prozac) because it can worsen some side effects (e.g., drowsiness, dizziness) as well as worsen your depression or anxiety symptoms.
- Antidepressant medications, like fluoxetine (Prozac), can raise the risk of suicidal thoughts. Contact your psychiatrist right away if you or your loved ones notice any new or worsening changes in your behavior or mood while taking the medication.
- Let your psychiatrist know if you're pregnant or thinking of becoming pregnant. They can talk with you about the benefits and risks of taking fluoxetine (Prozac) during pregnancy, as well as other treatment options. This is important because untreated mental health conditions during pregnancy can be harmful for you and your baby.
- Fluoxetine (Prozac) can get into breastmilk and cause side effects (e.g., fussiness, sleepiness) in breastfed babies. Let your psychiatrist know if you're breastfeeding. They'll discuss the risks and benefits of continuing fluoxetine (Prozac).

Risks and warnings for Fluoxetine (Prozac)
Fluoxetine (Prozac) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Worsening depression, suicidal thoughts and behavior
- Risk factors: Age under 24 years old | History of depression or other mental health conditions
Taking fluoxetine (Prozac) can make your depression worse and cause you to have thoughts of suicide or harming yourself. The risk is highest if you're 24 years of age or younger, during the first few weeks of taking the medication, and when your dose changes. If you or anyone around you notice that you have suicidal thoughts or unusual behavior (e.g., anxiety, panic attacks, difficulty sleeping, feeling angry or irritated, restlessness) while taking fluoxetine (Prozac), get medical help right away.
Anxiety and trouble sleeping
Fluoxetine (Prozac) can cause anxiety and trouble sleeping in some people. If this side effect is very bothersome for you, talk with your psychiatrist.
Serotonin syndrome
- Risk factors: Taking other medications that raise serotonin levels in your brain
Some people taking fluoxetine (Prozac) have developed a rare, but potentially life-threatening condition called serotonin syndrome. This condition happens where there's too much serotonin in the brain. Your risk for serotonin syndrome is higher if you use fluoxetine (Prozac) with other medications that can raise your serotonin levels, such as certain antidepressants, mental health medications, pain medications, and migraine medications. Let your psychiatrist know about all the medications you take before starting fluoxetine (Prozac). Also, don't start any new medications without talking to your psychiatrist first. Symptoms of serotonin syndrome include fast heart rate, sweating, muscle stiffness or spasms, fever, and confusion. Get medical help right away if you have any of these symptoms.
Severe allergic reactions
Severe allergic reactions to fluoxetine (Prozac) are possible, including life-threatening reactions like facial swelling, shock, and anaphylaxis (closing of the throat). If you notice hives, rash, red skin, swelling of the lips or tongue, or difficulty breathing after using fluoxetine (Prozac), get medical attention right away.
Not for use alone in bipolar disorder
Fluoxetine (Prozac) can be taken for depression from bipolar disorder only if it's taken together with olanzapine (Zyprexa). This is because taking fluoxetine (Prozac) alone can trigger a bipolar manic episode. Before starting fluoxetine (Prozac), your psychiatrist will check to see if you have or are at risk for bipolar disorder. Talk to your psychiatrist right away if you or your loved ones notice unusual changes in your behavior, such as racing thoughts, restlessness, getting easily distracted, or unusual talkativeness.
Risk of bleeding
- Risk factors: Taking blood-thinners or other medications that raise your risk of bleeding
Fluoxetine (Prozac) can raise your risk of severe bleeding or bruising, especially if you're also taking antiplatelets (e.g., aspirin, clopidogrel (Plavix)) or anticoagulants (e.g., warfarin (Coumadin), apixaban (Eliquis), rivaroxaban (Xarelto)). Get medical help if you get bruising that doesn't improve, black-colored stools, pink or red-colored urine, coughing up or vomiting blood, or unusual bleeding from the nose or gums.
Glaucoma
- Risk factors: History of angle-closure glaucoma
Fluoxetine (Prozac) can lead to or worsen angle-closure glaucoma. You might need to see your optometrist regularly and get eye exams to check your eyes and make sure your vision isn't worsening. Contact your optometrist or psychiatrist if you notice changes in your vision after starting fluoxetine (Prozac).
Low blood sodium levels
- Risk factors: Older adults | Taking diuretic medications
Fluoxetine (Prozac) can cause low blood sodium levels. Your provider might closely monitor your blood sodium levels before and during treatment with fluoxetine (Prozac). Get medical help right away if you experience weakness, confusion, difficulty concentrating, headache, or memory problems because these could be signs of low blood sodium levels, which is a medical emergency.
Life-threatening abnormal heart rhythm (QT prolongation)
- Risk factors: Low blood potassium or magnesium levels | Older age | Kidney problems | History of heart problems, slow heart rate, or other abnormal heart rhythms (arrhythmias) | Personal or family history of long QT syndrome | Taking other medications that cause QT prolongation
Fluoxetine (Prozac) can affect your heart rhythm, which can be serious and life-threatening. One example includes lengthening the time period from when the heart pumps and then relaxes. This is known as QT prolongation. Your risk is higher if you have certain factors, including abnormal electrolyte levels, heart rhythm problems, or are taking other medications that cause heart rhythm problems, such as amiodarone (Pacerone) and ciprofloxacin (Cipro), among others. To lower your risk, your psychiatrist or primary care provider might periodically monitor your heart and perform electrocardiograms (EKGs) to make sure your heart rhythm is normal. If you feel your chest pounding, have shortness of breath, have chest pain, or feel faint or lightheaded while taking fluoxetine (Prozac), call 911 right away.
