How it works
Ketoprofen blocks the COX enzymes that make prostaglandins, reducing pain, swelling and inflammation in affected tissues.
How it is taken
Available as capsules and tablets (including modified-release), gels for the skin, and suppositories. Take or apply it exactly as your doctor, pharmacist or the label directs. Oral forms are usually taken with or after food. The topical gel can make skin more sensitive to sunlight, so protect treated areas from sun.
No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.
Common side effects
- Indigestion, heartburn or stomach discomfort
- Nausea
