What is the American version of Voltaren? A comprehensive guide to diclofenac gel

According to the U.S. Food and Drug Administration (FDA), Voltaren gel became available over-the-counter (OTC) in February 2020 after a process known as an 'Rx-to-OTC switch'. This means that the American version of Voltaren, now branded as Voltaren Arthritis Pain gel, is widely available to consumers without a prescription. While known internationally as Voltaren Emulgel, the product found in U.S. stores contains the same key ingredient, diclofenac sodium.

Understanding the American Version of Voltaren

For many years, the topical form of Voltaren was only available with a prescription in the United States. However, after the FDA approved its non-prescription use, the product was rebranded for the American market. The American version, Voltaren Arthritis Pain gel, is formulated with 1% diclofenac sodium, the same concentration as its original prescription-strength version. Its purpose is to temporarily relieve pain associated with arthritis in certain joints.

The formulation, sometimes referred to as Emulgel internationally, allows the diclofenac to penetrate deeply into the skin to target pain at the site of inflammation. This is different from oral pain relievers that act systemically throughout the body. For this reason, Voltaren Arthritis Pain gel is a popular alternative for those who prefer not to take oral medications for joint pain.

The Active Ingredient: Diclofenac Sodium

The heart of Voltaren's effectiveness lies in its active ingredient, diclofenac sodium. This compound is a nonsteroidal anti-inflammatory drug (NSAID), a class of medications that includes familiar names like ibuprofen (Advil, Motrin) and naproxen (Aleve). Unlike oral NSAIDs, the diclofenac in Voltaren gel is applied topically, which reduces the amount of the drug absorbed systemically. This localized application helps concentrate the pain-fighting action where it is needed most. Diclofenac works by inhibiting certain enzymes in the body that produce prostaglandins, which are compounds that contribute to inflammation and pain.

Proper Application

Effective use of Voltaren Arthritis Pain gel requires following the directions carefully. It is important to use the included dosing card to measure the correct amount for each application.

General Guidelines for Applying Voltaren Arthritis Pain Gel:

1. Measure the amount: Use the provided dosing card to measure the appropriate amount of gel for the affected area. The amount varies depending on whether it is for an upper body area (hand, wrist, or elbow) or a lower body area (foot, ankle, or knee).
2. Clean the area: Ensure the skin is clean, dry, and free of cuts, rashes, or open wounds before applying.
3. Rub into skin: Gently rub the gel into the affected joint until it is fully absorbed.
4. Wait before washing: Wait at least one hour before washing the treated area, unless you are treating your hands.
5. Wash your hands: Always wash your hands thoroughly after applying the gel, unless the hands are the area being treated.
6. Apply as directed: Apply the gel as directed on the packaging or by a healthcare professional. Avoid exceeding the recommended frequency or using it on more than the specified number of body areas at a time.

Important Safety Information and Warnings

While considered safe for most users when directions are followed, Voltaren Arthritis Pain gel carries important warnings, similar to other NSAIDs.

Common Side Effects:

• Skin irritation, redness, or itching at the application site
• Dryness or peeling of the skin
• Mild stomach pain, constipation, or gas

Serious Warnings (Boxed Warning):

• Heart Attack and Stroke Risk: NSAIDs, including topical diclofenac, can increase the risk of heart attack, heart failure, and stroke, especially with longer use or higher doses. The risk may be greater for those with heart disease.
• Stomach Bleeding Risk: Serious gastrointestinal bleeding, ulceration, or perforation can occur with NSAID use. The risk is higher for older individuals, those with a history of stomach issues, or those using blood thinners.

It is crucial to consult a healthcare provider before using Voltaren, particularly if you have pre-existing health conditions. Do not use this product right before or after heart surgery.

The Availability of Generic Diclofenac Gel

For cost-conscious consumers, it is important to note that generic versions of diclofenac sodium topical gel 1% are also available in the U.S.. Retailers market these products under their own store brand labels. These generic versions contain the same active ingredient and concentration as the brand-name Voltaren Arthritis Pain gel, offering an equally effective and often more affordable option.

Conclusion

The American version of Voltaren is now widely available over-the-counter as Voltaren Arthritis Pain gel, or its generic equivalent, diclofenac sodium topical gel 1%. Its active ingredient, diclofenac, offers targeted, anti-inflammatory relief for arthritis pain in specific joints. Consumers no longer need a prescription for the 1% concentration, which is the same strength as the original formula. While effective, users should be aware of the associated risks and consult a healthcare professional to ensure safe use, especially regarding the boxed warnings concerning cardiovascular and gastrointestinal risks. For most adults seeking localized relief from arthritis symptoms, Voltaren Arthritis Pain gel provides a valuable topical treatment option.
