Frequently asked questions

Both Felex 100mg Capsule and paracetamol help in relieving pain, but they work in entirely different ways. When paracetamol is given with Felex 100mg Capsule, pain relief is better as compared to single drug use. However, both can cause liver toxicity, so monitoring of liver function is very important when taken together.
Felex 100mg Capsule can be used to relieve pain associated with osteoarthritis and post-orthopedic surgery pain. It is especially useful for patients who cannot take NSAIDs because of the risk of NSAID-induced gastritis.
Felex 100mg Capsule is not approved for the treatment of epilepsy. However, a few animal studies have shown a beneficial effect of Felex 100mg Capsule for treating epilepsy, and this effect is still being explored.
