The recommended dosage of Voltaren (diclofenac sodium) for adults usually ranges from 75 mg to 150 mg per day depending on the condition being treated. For milder symptoms or long-term treatment, doses of 75-100 mg per day may be sufficient. For more severe symptoms such as osteoarthritis, the dose may be 100-150 mg per day, divided into multiple doses like 50 mg two or three times a day or 75 mg twice a day. Prolonged-release tablets are usually taken once daily, often in the evening if symptoms are worse at night or in the morning. Voltaren Rapid (25 mg tablets) for conditions like menstrual pain might be taken as 2 tablets initially, followed by 1 or 2 tablets every 8 hours, with a maximum of 8 tablets in 24 hours. It is important never to exceed the dose prescribed by a doctor and to use the lowest effective dose for the shortest duration to minimize side effects. Voltaren should be used with caution or avoided in certain populations, such as patients with cardiovascular issues or severe kidney or liver impairment. Always follow the exact dosage prescribed by a healthcare professional, and do not self-medicate or exceed the recommended daily dose, which is generally capped at 150 mg per day for adults.
