Voltaren Arthritis Pain Gel
Voltaren Arthritis Pain Gel, a topical formulation of the nonsteroidal anti-inflammatory drug (NSAID) diclofenac sodium, is engineered for direct application to arthritic joints. Its primary mechanism of action involves the inhibition of cyclooxygenase (COX) enzymes, which play a crucial role in the synthesis of prostaglandins—lipid compounds associated with pain, inflammation, and fever. By mitigating the production of these mediators at the site of application, Voltaren Gel offers targeted relief from arthritis-induced discomfort without the systemic side effects commonly associated with oral NSAIDs.
To optimize the therapeutic benefits of Voltaren Arthritis Pain Gel while minimizing potential risks, adherence to the following guidelines is recommended:
- Apply a thin layer of the gel to the affected joint four times daily, ensuring comprehensive coverage without excessive application.
- Utilize the dosing card provided to accurately measure the prescribed amount of gel for each use.
- The hands should be washed thoroughly after the application of the gel, except when the treatment targets the hands themselves.
- Direct contact with the eyes, mucous membranes, and any areas of broken skin should be avoided to prevent irritation.
While Voltaren Gel is generally well-tolerated, its use may elicit local and systemic side effects. Commonly reported adverse effects at the site of application include:
- Dermatitis, manifesting as erythema, itching, and swelling.
- Dry skin, scaling, or slight burning sensation shortly after application.
Systemic absorption of diclofenac from topical application is lower compared to oral administration, yet it is important to be vigilant for signs of systemic NSAID-related side effects, particularly in individuals with prolonged usage or compromised skin integrity.
Voltaren Gel is expressly indicated for the relief of arthritis pain, offering an efficacious alternative for patients seeking localized symptom management. Indications include:
- Management of osteoarthritis-related pain, particularly in joints amenable to topical treatment such as knees and hands.
- It serves as an adjunct to other non-medication therapies and lifestyle modifications aimed at reducing the functional limitations imposed by arthritis.
The application of Voltaren Gel as part of a comprehensive arthritis management plan emphasizes its role in improving joint mobility and quality of life for individuals experiencing mild to moderate arthritis pain.
The application of Voltaren Arthritis Pain Gel, containing diclofenac sodium, necessitates careful consideration of its pharmacological profile and potential for adverse effects. Primary concerns include:
- Dermal Reactions: Prolonged use may lead to localized skin reactions, underscoring the importance of monitoring for signs of dermatitis or eczema.
- Systemic Absorption: Although minimal, systemic absorption of diclofenac can occur, warranting caution in patients with a history of cardiovascular or renal conditions.

When Not to Use?
Voltaren Gel is contraindicated in certain populations and conditions, emphasizing the necessity for patient-specific evaluations:
- Individuals with a known hypersensitivity to diclofenac, aspirin, or other NSAIDs.
- Patients with active or history of peptic ulcer disease or gastrointestinal bleeding.
- During the third trimester of pregnancy, due to potential risk of fetal harm.
The use of Voltaren Gel is associated with several warnings that align with those of systemic NSAIDs, including:
- Cardiovascular Risk: NSAIDs may increase the risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. The risk may increase with duration of use.
- Gastrointestinal Risk: NSAIDs cause an increased risk of serious gastrointestinal adverse events, including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal.
Nonsteroidal anti-inflammatory drugs (including diclofenac) may rarely increase the risk for a heart attack or stroke. This effect can happen at any time while using this drug but is more likely if you use it for a long time. The risk may be greater in older adults or if you have heart disease or increased risk for heart disease (for example, due to smoking, family history of heart disease, or conditions such as high blood pressure or diabetes). Do not use this drug right before or after heart bypass surgery (CABG).
Also, this drug may rarely cause serious (rarely fatal) bleeding from the stomach or intestines. This side effect can occur without warning symptoms at any time while using diclofenac. Older adults may be at higher risk for this effect. ()
Stop using diclofenac and get medical help right away if you notice any of the following rare but very serious side effects: stomach/abdominal pain that doesn't go away, black/bloody stools, vomit that looks like coffee grounds, chest/jaw/left arm pain, shortness of breath, unusual sweating, confusion, weakness on one side of the body, sudden vision changes, trouble speaking.
Talk with your doctor or pharmacist about the benefits and risks of using this medication.
The dosing regimen for Voltaren Gel must be adhered to meticulously to mitigate risks and optimize efficacy:
- Apply 4 grams of the gel to the affected joint four times daily.
- The maximum daily dose should not exceed 16 grams for any single joint of the lower body and 8 grams for joints of the upper body.
Voltaren Gel's interactions mirror those of systemic diclofenac, necessitating careful medication reconciliation:
- Anticoagulants: Increased risk of bleeding.
- Other topical treatments: Concurrent use may affect absorption or enhance local adverse effects.
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Some products that may interact with this drug include: aliskiren, ACE inhibitors (such as captopril, lisinopril), angiotensin II receptor blockers (such as losartan, valsartan), cidofovir, corticosteroids (such as dexamethasone, prednisone), lithium, methotrexate, other products applied to treated skin, “water pills” (diuretics such as furosemide).
This medication may increase the risk of bleeding when used with other drugs that also may cause bleeding. Examples include antiplatelet drugs such as clopidogrel, “blood thinners” such as dabigatran/enoxaparin/warfarin, erlotinib, among others.
Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (aspirin, NSAIDs such as ibuprofen, naproxen, or ketorolac). These drugs are similar to diclofenac and may increase your risk of side effects if taken together. However, if your doctor has directed you to take low-dose aspirin to prevent heart attack or stroke (usually 81-162 milligrams a day), you should continue taking the aspirin unless your doctor instructs you otherwise. Ask your doctor or pharmacist for more details.
