What is Tolfenamic Acid?
Tolfenamic Acid is a medication classified as a NSAID (Non-Steroidal Anti-Inflammatory Drug). It is primarily used for its analgesic (pain relief), anti-inflammatory, and antipyretic (fever-reducing) properties. It plays a significant role in managing various acute and chronic pain conditions. Tolfenamic Acid is particularly recognized for its effectiveness in migraine treatment and other types of headaches, as well as for menstrual pain and musculoskeletal discomfort.
How Does it Work?
The therapeutic actions of Tolfenamic Acid stem from its ability to inhibit the synthesis of prostaglandins. Prostaglandins are chemical messengers in the body that contribute to inflammation, pain signaling, and fever. Tolfenamic Acid achieves this inhibition by blocking the activity of cyclooxygenase (COX) enzymes, specifically COX-1 and COX-2. While COX-1 is involved in normal bodily functions, COX-2 is primarily activated during injury and inflammation. By reducing prostaglandin production, Tolfenamic Acid effectively diminishes inflammation, alleviates pain, and lowers fever. For migraines, its action extends beyond general anti-inflammatory effects, also impacting neurogenic inflammation associated with migraine pathophysiology, making it a targeted treatment for acute attacks.
Medical Uses
Tolfenamic Acid is prescribed for conditions where pain, inflammation, and fever are prominent. Its main medical uses include:
- Acute Migraine Attacks: Effective for moderate to severe migraines, reducing headache pain, photophobia, and phonophobia.
- Tension Headaches: Provides relief from pain associated with tension-type headaches.
- Dysmenorrhea (Menstrual Pain): Alleviates severe cramping and discomfort during menstruation.
- Musculoskeletal Pain: Used for conditions like sprains, strains, back pain, and osteoarthritis.
- Post-operative Pain: Manages pain and inflammation following surgical procedures.
It offers symptomatic relief but does not cure underlying chronic conditions.
Dosage
Dosage of Tolfenamic Acid varies by condition, patient age, and response. Always follow healthcare professional's instructions. It is generally taken orally.
- For Acute Migraine Attacks: A typical adult dose is 200 mg at the first sign of migraine, repeatable after 1-2 hours if needed, up to a maximum daily dose (e.g., 400-600 mg).
- For General Pain and Inflammation: Doses usually range from 100 mg to 200 mg, 1-3 times daily.
Take with food or milk to reduce gastrointestinal side effects. Do not exceed recommended dose or duration without medical advice.

- Cardiovascular Risks: Increased risk of heart attack or stroke (chest pain, shortness of breath).
- Allergic Reactions: Severe rash, swelling of face/throat, difficulty breathing.
Caution is advised for patients with a history of GI issues, heart/kidney disease, or asthma.
Drug Interactions
Tolfenamic Acid can interact with other medications. Inform your doctor about all current medications.
Key Interactions Include:
- Other NSAIDs/Corticosteroids: Increased risk of GI bleeding.
- Anticoagulants (e.g., Warfarin) and Antiplatelet Drugs: Increased bleeding risk.
- Diuretics and ACE Inhibitors: Reduced blood pressure-lowering effects, increased kidney risk.
- Lithium and Methotrexate: Increased toxicity levels.
- SSRIs: May increase GI bleeding risk.
Always consult your healthcare provider before combining medications with Tolfenamic Acid.
