Understanding Diclofenac: Uses, Dosage, and Side Effects

Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) commonly prescribed to relieve pain and inflammation. It is often used to manage conditions such as arthritis, migraines, and other acute pain scenarios. This guide provides a detailed overview of diclofenac, including its mechanism of action, recommended usage, and potential side effects.

What is Diclofenac?

Diclofenac is an NSAID that works by reducing the substances in the body that cause inflammation and pain. It is available in various forms, including tablets, topical gels, and injections. This medication is often prescribed for conditions like osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute migraines.

Mechanism of Action

Diclofenac works by inhibiting the cyclooxygenase (COX) enzymes, COX-1 and COX-2. These enzymes play a crucial role in the production of prostaglandins, compounds that promote inflammation, pain, and fever. By blocking these enzymes, diclofenac effectively reduces the symptoms associated with inflammation.

Diclofenac should be used as prescribed by a healthcare professional. The dosage may vary based on the condition being treated, the patient’s age, and overall health. Here are general guidelines:

– Oral Tablets: Taken with a full glass of water. It is advisable to take it with food to minimize stomach upset.
– Topical Gels: Applied directly to the skin over the affected area. Wash hands before and after application.
– Injections: Administered by a healthcare professional in a clinical setting.

Recommended Dosages
