Naproxen is a non-steroidal anti-inflammatory drug (NSAID). It has a similar method of action of the over-the-counter medicine ibuprofen; it blocks chemicals that cause pain and inflammation at the site of injury. Naproxen is a stronger anti-inflammatory than ibuprofen and is used in moderate pain and inflammation or where ibuprofen has been ineffective.
Naproxen is used to treat pain or inflammation caused by conditions such as:
- Back pain
- Menstrual cramps
Naproxen is thought to have less side effects than other anti-inflammatory drugs, with it being less harsh on the stomach than treatments such as ibuprofen or diclofenac. At The Indpendent Pharmacy we only supply Naproxen in gastro-resistant tablets, which means that they have an extra protective coating to help reduce the chance of side effects even further. Naproxen should always be taken with or after food to help protect the stomach lining.
Naproxen is suitable to purchase online for those with short-term, non-serious injuries that do not require a visit to the doctor. For serious injuries or long-term conditions, it is more appropriate to see your GP for examination and management.
You can take Naproxen with paracetamol and opioid-type painkillers such as codeine, co-codamol, tramadol or morphine. However, don't take aspirin, or other related anti-inflammatory painkillers (NSAIDs) like ibuprofen or diclofenac, as this heightens the risk of side effects on the stomach and intestines. If you take selective inhibitors of COX-2 such as etoricoxib or celecoxib you should not take Naproxen for the same reason.
It is important to remember that cold and flu remedies and over-the-counter painkillers often contain ibuprofen or aspirin. For this reason, you should avoid these medications while you're taking naproxen to prevent an accidental interaction. Check the ingredients of other medicines you wish to take before taking them with naproxen, or ask us for advice.
You should also check with us before you use anti-inflammatory gels (such as ibuprofen, diclofenac, ketoprofen or piroxicam) alongside Naproxen tablets, because this is not safe for everyone.
