How Voltaren® Works

Diclofenac works by blocking enzymes called cyclooxygenase (COX-1 and COX-2) which produce prostaglandins. Prostaglandins are substances that promote inflammation and pain. By reducing prostaglandin production, Voltaren® helps reduce inflammation and discomfort.

Dosage Instructions of Voltaren®

Voltaren® is available in several forms in Canada, including oral tablets, topical gels, and suppositories. This variety allows for different methods of administration depending on patient needs and medical advice.

Always follow the doctor’s instructions or the product monograph for dosage. Do not exceed the recommended dose or duration. Take tablets with food or milk to reduce stomach upset. Avoid self-adjusting the dose without medical guidance.

Storage Instructions

Store Voltaren® at room temperature between 15°C and 30°C, away from moisture and heat. Keep out of reach of children. Do not use after the expiry date printed on the package.

Side Effects of Voltaren®

Common side effects may include stomach upset, nausea, or mild skin irritation with topical use. Serious side effects, although rare, can include gastrointestinal bleeding, allergic reactions, or liver issues. Contact a healthcare professional if you experience severe symptoms.
