Can I take Paracetamol and Naproxen together?

Drug interaction guide

It is generally safe to take paracetamol and naproxen together. They are different types of painkillers that work in different ways, and taking them at the same time can provide better pain relief for some people. However, you must be careful not to exceed the maximum daily dose for either medication.

Why this happens

Paracetamol works mainly in the central nervous system to reduce pain signals and fever. Naproxen is a Non-Steroidal Anti-Inflammatory Drug (NSAID) that works by blocking chemicals called prostaglandins that cause pain and inflammation at the site of an injury. Because they target pain through different pathways, their effects can be additive without interfering with how the body processes each drug.

What you should do

You can take these two medicines together if needed. Always follow the dosage instructions on the packaging or as directed by your pharmacist. Ensure you do not take any other products containing paracetamol (like some cold and flu remedies) or other NSAIDs (like ibuprofen or aspirin) at the same time. It is best to take naproxen with or after food to protect your stomach.

Important precautions

Asthma

Do not take this medicine if you have asthma that is sensitive to aspirin or other NSAIDs, as it can trigger a life-threatening asthma attack.

Stomach ulcers or bleeding

This medicine significantly increases the risk of stomach ulcers and internal bleeding. Avoid it if you have a history of stomach problems or are taking blood-thinning medication.

Liver health and dosing safety

Never exceed the maximum dose (usually 8 tablets in 24 hours) or take with other products containing paracetamol (such as cold and flu remedies), as this can cause fatal liver damage.

Food and drink warnings

Alcohol

While an occasional drink is generally safe, chronic heavy drinking or binge drinking increases the risk of serious liver damage when taking paracetamol. It is best to limit alcohol intake while using this medicine.

Food (General)

Naproxen should ideally be taken with or after food. This helps to protect the lining of your stomach and reduces the risk of indigestion or stomach ache.
