Can I take Amitriptyline and Paracetamol together?

Why this happens

Amitriptyline and paracetamol are processed by the body using different pathways and do not interfere with how the other drug works, is absorbed, or is cleared from the system.

You can take these medicines together as prescribed or according to the packet instructions. Always ensure you do not exceed the maximum daily dose of paracetamol (usually 4 grams or eight 500mg tablets in 24 hours). If you feel unusually drowsy, speak to your doctor or pharmacist.

Liver disease or heavy alcohol consumption

Taking paracetamol if you have liver problems or drink large amounts of alcohol significantly increases the risk of severe, life-threatening liver damage, even at standard doses.

Heart conditions (e.g. recent heart attack, heart rhythm disorders)

Amitriptyline can affect your heart rhythm and should not be used if you have recently had a heart attack or have certain heart rhythm problems, as it may lead to dangerous cardiac events.

Glaucoma (specifically acute angle-closure glaucoma)

Amitriptyline can increase the pressure inside your eye. If you have glaucoma, it can trigger an acute attack, which is a medical emergency.

Alcohol

Drinking alcohol while taking amitriptyline can make you feel very sleepy and unsteady on your feet. It is best to avoid alcohol, especially when you first start treatment or if your dose is increased.

Caffeine (Coffee, tea, energy drinks)

Amitriptyline can sometimes cause a fast or irregular heartbeat. High amounts of caffeine can worsen these side effects or increase feelings of anxiety and restlessness.
