Due to the increased risk of side effects, mainly gastrointestinal bleeding, the concomitant use of acemetacin contained in Rantudil Forte and other non-steroidal anti-inflammatory drugs (NSAIDs), which, apart from the Olfen and Nimesil medicinal products mentioned in the question, include most analgesics, are not recommended. Non-NSAIDs include paracetamol (e.g. Apap, Efferalgan) and metamizole sodium (e.g. Pyralgina, Gardan). Theoretically, both of these drugs can be used concomitantly with Rantudil Forte, but due to the risk of increased nephrotoxicity of paracetamol in combination with acemetacin, metamizole seems to be a safer alternative. However, using a second painkiller without consulting a doctor is a short-term solution. I encourage you to consult a doctor about the appropriateness of increasing the dose of acemetacin. The maximum is allowed to use 180 mg of acemetacin per day (3 tablets of Rantudil Forte). It is possible that after collecting a thorough history, the doctor will decide to introduce a drug that complements the action of the painkiller, e.g. a muscle relaxant. So do not delay the visit to a specialist.
