Ketoprofen: Uses, Dosage, Side Effects, And Safety Guide
Comprehensive guide to ketoprofen: uses, dosage, side effects, and safety for managing pain and inflammation effectively.
Ketoprofen is a non-steroidal anti-inflammatory drug (NSAID) used to treat pain and inflammation in conditions such as muscle and joint problems, including rheumatoid arthritis and osteoarthritis. It provides short-term relief by reducing pain, swelling, and stiffness.
About ketoprofen
Ketoprofen belongs to the group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). It works by blocking the action of cyclo-oxygenase (COX) enzymes. These enzymes produce chemicals called prostaglandins, which cause pain, swelling, and inflammation. By reducing prostaglandin levels, ketoprofen eases symptoms of pain and inflammation.
Available as capsules (immediate-release like Larafen) or modified-release capsules (sustained-release like Oruvail), ketoprofen is typically prescribed for short-term use, up to one week for acute pain or longer under medical supervision for chronic conditions like arthritis.
Before taking ketoprofen
Who can and cannot take ketoprofen tablets or capsules
Most adults can take ketoprofen safely. However, do not take it if:
- You are allergic to ketoprofen, aspirin, ibuprofen, naproxen, or other NSAIDs. Symptoms of allergy include rash, swelling, or breathing difficulties.
- You have or have had a stomach ulcer, bleeding, or perforation in the stomach or intestines.
- You have severe heart failure, severe kidney or liver problems.
- You are in the last three months of pregnancy, as NSAIDs can harm the fetus.
- You have active bleeding or bleeding disorders.
Caution is needed if you have heart disease, high blood pressure, diabetes, high cholesterol, a history of stomach bleeding, asthma, or are over 65, as risks of serious side effects increase.
Other medicines, food, and drink
Ketoprofen can interact with:
- Other NSAIDs, aspirin, or painkillers – increases risk of side effects.
- Blood thinners (e.g., warfarin), steroids, antidepressants (SSRIs), or blood pressure medicines.
- Alcohol – heightens stomach bleeding risk.
Take with food or milk to protect the stomach.
Pregnancy, breastfeeding, and fertility
Avoid in the third trimester due to risks of fetal kidney damage and heart problems. Limited data in early pregnancy; consult a doctor. Ketoprofen passes into breast milk in small amounts; use only if benefits outweigh risks. It may temporarily affect female fertility.
