Drug Description


Diclofenac is classified as a nonsteroidal anti-inflammatory drug (NSAID) and is prescribed to alleviate pain and inflammation associated with knee arthritis while enhancing joint mobility and flexibility. 

Uses and Dosage 

Before the initial usage of the pump, this is imperative to detach the cap and prepare the pump as directed by the manufacturer. 

Administer the prescribed medication to unsoiled, dry skin following the instructions of your medical practitioner, generally twice daily on the affected knee(s). Firmly push down on the pump head twice and dispense the medication into the palm of your hand. Spread the drug uniformly around the knee’s anterior, posterior, and lateral parts. If instructed by your doctor, repeat the process on the other knee. Allow the medication to dry for several minutes. Refrain from covering the treated knee with clothing until this is entirely dry. Avoid using sunscreen, insect repellent, lotion, or other topical products on the treated area until completely dry. 

Ensure to wash your hands before and after applying the medication. Prevent the medicines from contacting the eyes, nose, or mouth. Do not bathe or shower for at least 30 minutes after application. Do not apply the medication to open wounds or infected or damaged skin. Unless your doctor advises, avoid wrapping, bandaging, or using heat (such as a heating pad) to the treated region. 

Use the medication as directed by your doctor to obtain maximum benefit. Do not exceed the prescribed amount, increase the frequency of administration, or use it for longer than required.
