Hello, In general, it is true that taking naproxen (non-steroidal anti-inflammatory drug) can have an effect on the kidneys. Non-steroidal anti-inflammatory drugs (NSAIDs) should always be used with caution in patients with kidney problems. In the short and long term, NSAIDs can reduce the kidney's ability to filter adequately. In your case, it would be relevant to see who prescribed this medication. If it was a doctor, it is possible that he or she decided to prescribe this medication for a short time to relieve your arm pain. If your kidney and clinical situation allows, it is possible to use naproxen for a short time without the risk of further damaging your kidneys despite your kidney condition. 😊 To help limit the potential risk to your kidneys from taking naproxen, here are some tips that may help: Limit naproxen use, which is to use the medication only as needed for the shortest time possible. If you have no contraindications, you could try using instead: Tylenol 500 mg 1 to 2 tablets by mouth every 4 to 6 hours as needed (maximum: 8 tablets per day). Alternatively, a topical anti-inflammatory (such as Voltaren) may be an option, to avoid the use of oral anti-inflammatory medication. If used properly, topical anti-inflammatories have a lower absorption than oral anti-inflammatories and therefore a lesser effect at the kidney level. (Important here to never combine topical and oral anti-inflammatories!!) Drink plenty of water during treatment.
