Ketoprofen: What is it? How does it work? Warnings, Indications and Side Effects

It belongs to the medicines known as non-steroidal anti-inflammatory drugs (NSAIDs).

It is used for the symptomatic treatment of rheumatoid arthritisosteoarthritis, and ankylosing spondylitis.

Ketoprofen can also treat pain associated with menstrual cramps and relieve pain after surgery (including dental surgery), postpartum pain, and mild to moderate pain associated with sprains and strains.

How does it work?

Ketoprofen relieves pain and reduces swelling and inflammation by reducing a substance in the body that causes inflammation and pain.

When Ketoprofen is applied to the skin as a gel, it only works in the area where you applied it instead of affecting your entire body. It is absorbed into your skin and then moves deeper into the areas of your body where there is inflammation (for example, your muscle).

Using a gel for the skin means that your body’s total amount of Ketoprofen remains low. This, in turn, means that you are much less likely to have a side effect of the medication.

Topical anti-inflammatories such as Ketoprofen are prescribed to adults; Generally, they are not suitable for children. Ketoprofen gel is available by prescription, and you can also buy some smaller packages without a prescription.
