Can I take Fluoxetine and Paracetamol together?

Why this happens

Fluoxetine and paracetamol are processed by different pathways in the liver and do not interfere with how the other is absorbed, broken down, or removed from the body. They also work on different systems in the body, so they do not increase each other's side effects.

What you should do

You can take paracetamol while taking fluoxetine. Always follow the dosage instructions on the paracetamol packaging and do not exceed the maximum daily dose (usually 4g or eight 500mg tablets in 24 hours). If you find you need to take paracetamol for more than a few days, or if your pain is not controlled, speak to your pharmacist or GP.

Important precautions

Bleeding disorders or use of blood thinners

Fluoxetine can increase your risk of bleeding, especially if you are already taking medicines that thin the blood (like warfarin) or non-steroidal anti-inflammatory drugs (like ibuprofen).

Liver disease or chronic alcohol use

You must strictly follow the dosage instructions; taking even slightly more than the recommended dose can cause life-threatening liver damage, particularly if you have existing liver issues or drink alcohol regularly.

Under 25 years old

In children and young adults, fluoxetine can occasionally increase thoughts of self-harm or suicide when first started; you must be closely monitored by family or a doctor during the first few weeks.

Food and drink warnings

Alcohol

It is best to avoid drinking alcohol while taking fluoxetine. Alcohol can increase the risk of side effects like drowsiness, dizziness, and difficulty concentrating.
