Before taking multiple medications, it’s important to understand any potential drug interactions.
Adderall is a prescription stimulant that contains two drugs: amphetamine and dextroamphetamine. Doctors typically use it to treat ADHD.
Prozac (fluoxetine) is a type of antidepressant called a selective serotonin reuptake inhibitor that works by increasing the activity of serotonin in your brain. Doctors prescribe it to treat conditions like:
- depression
- panic disorder
- bulimia
- premenstrual dysphoric disorder
If you have any one of the above conditions and ADHD, you might consider taking both Prozac and Adderall. However, medical professionals don’t usually recommend this due to the risk of serious side effects.
Is it safe to mix Prozac and Adderall?

Prozac, the branded form of fluoxetine, may increase the effects of both of the main active ingredients of Adderall (amphetamine and dextroamphetamine). This could lead to side effects that include:
- anxiety
- racing thoughts
- nervousness
- restlessness
- nausea
- confusion
Some older 2015 research found that mixing stimulants such as Adderall with antidepressants like Prozac was common among a cohort of students despite the risks. A total of 93% of people who combined the medications reported experiencing anxiety, which may have been due to the interaction of the drugs.
What’s more, Prozac is a CYP2D6 inhibitor, meaning it blocks a certain enzyme that helps your body absorb medications. The Food and Drug Administration (FDA) warns that Adderall interacts with CYP2D6 inhibitors and increases serotonin, resulting in a higher risk of serotonin syndrome.
This is a rare condition that can have serious side effects. So, if a doctor prescribes Prozac and Adderall, they should closely monitor you to make sure there are no serious side effects.
What is serotonin syndrome?
Serotonin syndrome happens when there is too much serotonin in your body. Drug interactions are a common cause, and almost everyone develops symptoms within 24 hours of taking the drug in question. This is why close monitoring by a doctor is important if you’re taking Prozac and Adderall.
Serotonin syndrome can cause the following symptoms:
- increased heart rate
- blurry vision
- dizziness
- hallucinations
- agitation
- muscle twitching or tremors
- nausea and vomiting
In rare cases, serotonin syndrome can result in coma and even death.
If you begin experiencing any of these symptoms while taking Adderall and Prozac, talk with your doctor. Don’t take Adderall and Prozac together unless your doctor closely monitors you.
