Diclofenac Gel for joint pain? Here's what you need to know! (Diclofenac Gel)

Joint pain and arthritis pain are a very annoying thing for many people, regardless of age, right? When the joints of the knees, elbows, and hands hurt, you can't even do your daily tasks properly. At times like this, your doctor may have told you to use a gel containing Diclofenac. You may have seen this under names like Voltaren Gel. So today, let's talk about this medicine, how to use it properly, and the most important things to be careful about.

What exactly is Diclofenac Gel?

Simply put, Diclofenac is a pain and swelling reliever . It belongs to a class of drugs called NSAIDs (Non-Steroidal Anti-Inflammatory Drugs) . You may have heard of drugs like Ibuprofen and Naproxen , which are also in the same family. However, this is not a pill that you take, but a gel that you apply to the skin where the pain is. Since it works directly on the painful joint, it can reduce some of the side effects that come with taking pills.

Things you need to tell your doctor before using this medicine

This is very important. If you have any of the following medical conditions or problems, you should definitely tell your doctor before using Diclofenac Gel .

Problem typeSituations you should report

How exactly do you use this?

This is very simple, but it must be followed exactly.

  • This is only for drinking, not drinking! This is for external use only.
  • Wash your hands thoroughly with soap before and after applying the gel. However, if you are applying the medicine to your hands, wash your hands only before applying it.
  • Do not apply to eyes, mouth, nose, or other areas with wounds .If you accidentally get it in your eyes, rinse thoroughly with clean water for several minutes.
  • Apply only the amount the doctor recommends, like a thin film, to the painful area. Applying too much will not make the pain go away quickly.
  • Do not apply more than the number of times your doctor tells you to (e.g., if 3 times a day, only 3 times).
  • Continue using it until your doctor tells you to stop.

What if the medicine is used too much?

If you think you have used more gel than you think, immediately call the National Poison Information Centre at the Colombo National Hospital . Or go to the Emergency Treatment Unit (ETU) of the nearest hospital.
