Febrax Tablets: Ingredients, Uses, Benefits, Dosage, Side Effects, Interactions

What is Febrax tablet?

Febrax tablet is a combination pain and fever medication that contains naproxen sodium and paracetamol as active ingredients. Naproxen works by blocking the enzyme that produces prostaglandins. Prostaglandins play an essential role in inflammation. The body produces them at the site of injured tissue, and they cause redness, heat, swelling, and pain.

On the other hand, paracetamol work by blocking chemical messengers in the brain that tell us we have pain. Paracetamol also reduces fever by affecting the chemical messengers in an area of the brain that regulates body temperature.

In combination, these two medication work in synergy to treat fever, pain, and conditions such as moderate musculoskeletal pain, otalgia, headache, common cold symptoms, postoperative tonsil, and oropharyngeal surgery, dental procedures, and trauma.

Each tablet of Febrax contains naproxen sodium 275mg and paracetamol 300mg.

Febrax may interact with other medications

Febrax oral tablets can interact with other medications, vitamins, or herbs you may be taking. An interaction is when a substance changes the way a drug works. This can be harmful or prevent the drug from working well.

To help avoid interactions, your doctor should manage all of your medications carefully. Be sure to tell your doctor about all medications, vitamins, or herbs you’re taking. To find out how this drug might interact with something else you’re taking, talk with your doctor or pharmacist.

Examples of drugs that can cause interactions with Febrax are listed below.

Antidepressant drugs

Combining selective serotonin reuptake inhibitors (SSRIs) with Febrax increases your risk of stomach and intestinal bleeding. Examples of these drugs include:

  • citalopram
  • fluoxetine
  • fluvoxamine
  • paroxetine
