Indications & Uses

Pharmacology

Diclofenac Sodium is a powerful non-steroidal anti-inflammatory drug (NSAID), valued for its strong anti-rheumatic, anti-inflammatory, analgesic and antipyretic effects, along with some uricosuric activity. It works by inhibiting prostaglandin biosynthesis, the process largely responsible for inflammation, pain and fever.

When taken with or after food, Diclofenac is absorbed rapidly and completely from the gastro-intestinal tract, reaching peak plasma concentrations on average within 2 hours. At therapeutic levels, it is 99.7% bound to plasma proteins. The drug is metabolized in the liver and undergoes first-pass metabolism.

Reference Information Only

Dosages shown are general references from official sources. Always consult your doctor or pharmacist for personalized dosing.

Adults:

Diclofenac FC Tablet

Adults take 75 to 150 mg a day in 2 to 3 divided doses, preferably after food. The dose should be reduced for long term use.

Diclofenac SR Tablet

Adults take 1 tablet daily, swallowed whole with liquid, preferably at meal times. If needed, the daily dose can be raised to 150 mg by adding conventional tablets. For children, the dose is 1 to 3 mg of diclofenac per kg of body weight daily in divided doses. In elderly or debilitated patients, the lowest effective dose is recommended, although the pharmacokinetics of diclofenac sodium is not affected to any clinically relevant extent by age.

Diclofenac Dispersible Tablet

Adults are recommended 2 to 3 tablets daily, with a maximum daily dose of 150 mg. In milder cases, 2 tablets of Diclofenac DT a day are enough. Diclofenac DT should preferably be taken before meals. It is not recommended for children for other indications except juvenile rheumatoid arthritis, where the recommended dose is 1 to 3 mg per kg of body weight. Diclofenac DT should be dropped into a half glass of water and the liquid stirred to help it disperse before it is swallowed. There is no information on using Diclofenac DT for more than 03 months.

Diclofenac TR Capsule

One capsule daily, preferably taken after mealtimes.

Diclofenac Suppository

Adults take a 50 mg suppository 2 to 3 times daily, with a maximum daily dose of 150 mg.

Diclofenac Injection

The usual adult dose is 1 ampoule daily. In serious cases, this may be increased to up to 2 ampoules daily.

Diclofenac Gel

For external use only. Depending on the size of the area being treated, 2 to 4 g of Diclofenac gel should be applied to the skin 3 to 4 times daily and rubbed in lightly over the affected area. This gel may also be used alongside treatment with other dosage forms of Diclofenac.

Side Effects

Voltafen is usually well tolerated, and side effects tend to be mild, uncommon and short-lived. Early in treatment, some patients notice stomach discomfort, belching, nausea, diarrhea, dizziness or headache, though these are generally mild. Fluid retention (swelling) and skin reactions such as rash or eczema have also been reported. With Voltafen Gel, local skin irritation, redness and rash can occur.

Cautions & Contraindications

Warnings & Precautions

Voltafen has, in rare cases, been associated with peptic ulceration or gastrointestinal bleeding during treatment. Elderly patients should be monitored closely. Voltafen Gel must not come into contact with the eyes or mucous membranes; after applying it, hands should be washed thoroughly, and the gel must never be swallowed.

Contraindications

Contraindicated in patients who are hypersensitive to any ingredient of the product, and in those with peptic ulcer disease. As with other non-steroidal anti-inflammatory drugs, Diclofenac should not be used in patients with known hypersensitivity to it. It is also contraindicated in patients who have had asthma attacks, urticaria, or acute rhinitis triggered by acetylsalicylic acid (aspirin) or other prostaglandin synthetase inhibitors. The gel formulation should not be applied under airtight, occlusive dressings.

Pregnancy & Breastfeeding

During pregnancy, Diclofenac should only be used when there is a compelling reason to do so, and at the lowest effective dose. It is not recommended during the first trimester. Because clinical data are insufficient, Diclofenac Sodium Gel is also not recommended for use during pregnancy. Only a very small amount of Diclofenac passes into breast milk, and no harmful effects on the infant are expected.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Storage

Keep Diclofenac Sodium in a cool, dry place away from light, and below 30°C. Keep it out of the reach of children.
