Can you use Nalgesin forte 550mg for lower leg pain or is Muscoflex enough?

It is not recommended to combine NSAIDs with each other due to the increased risk of side effects, and does not increase the therapeutic effect on the patient.

Nalgesin Forte is an analgesic and anti-inflammatory medicine containing naproxen at a dose of 550 mg. Muscoflex, on the other hand, is a combination of paracetamol, diclofenac and serrapeptase.

In the event that the use of over-the-counter preparations turns out to be insufficient, I encourage you to take advantage of the teleconsultation:
