There are many different forms of diclofenac; your healthcare provider will recommend a dosage based on the specific condition being treated, the particular product (tablets, capsules, gels, skin patches, or eye drops), and various other factors. It is generally recommended to take your dosage of oral diclofenac with food to help prevent stomach upset; however, food may cause this medicine to work more slowly.
Diclofenac Dosage: An Introduction
The dose of diclofenac that your healthcare provider prescribes will vary depending on a number of factors, including:
- The particular diclofenac product
- The medical condition being treated
- Other medical conditions you may have
- Other medications you may currently be taking.
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
PainThe standard recommended oral diclofenac dosage for pain is 50 mg three times daily (for Cataflam®) or 25 mg four times daily (for Zipsor®). For the patch form (Flector®), the recommended dosing is one patch applied to the most painful area every 12 hours.
OsteoarthritisFor symptoms of osteoarthritis, the recommended dosage for regular diclofenac tablets is 50 mg two or three times a day (for Cataflam or Voltaren®) or 75 mg twice daily (for Voltaren only). For extended-release diclofenac tablets (Voltaren®-XR), the recommended dosage for the relief of osteoarthritis symptoms is Voltaren-XR 100 mg, once per day.
The standard recommended diclofenac gel (Voltaren® Gel, 1 percent) dosage for osteoarthritis of the upper extremity is 2 grams applied to the affected elbow, wrist, or hand four times daily. For the lower extremity, the standard dosing is 4 grams applied to the affected knee, ankle, or foot four times daily. The total dose (over all areas of the body) should not exceed 32 grams per day.
For diclofenac topical solution (Pennsaid®), the recommended dosage for osteoarthritis of the knee is 40 drops per affected knee four times per day. The drops should be applied 10 at a time to help prevent spillage.
