Febuxostat 40 mg tablets work by blocking the xanthine oxidase enzyme, reducing uric acid levels in the blood to manage chronic gout—a painful arthritis condition caused by uric acid crystal buildup in joints like the big toe. It helps ease severe pain, tenderness, and redness in gout flares but is only used when high uric acid causes symptoms. Taken orally, it provides steady control with regular use, helping prevent joint damage over time.
Primary Uses
- Manages chronic gout by reducing uric acid levels.
Indications
Used for chronic hyperuricemia (high uric acid in blood) in adults with gout symptoms, such as joint pain, tenderness, or redness.
Side Effects
Some may experience nausea, throat irritation, decreased libido, unexpected weight changes, rash, or joint pain. Rarely, liver function changes or severe allergic reactions may occur. Contact your doctor if symptoms persist or worsen.
Warnings
- Pregnancy: Use only if necessary; consult your doctor due to limited safety data.
- Lactation: Effects unclear; avoid unless advised by your doctor.
- Driving: Generally safe, but avoid if dizziness occurs.

Precautions

- Inform your doctor of all medications and medical history, especially cancer or organ transplants.
Contraindications
Avoid if:
