Voltaren - Anti-Inflammatory Pain Gel

For millions of people suffering from arthritis, tendon injuries, muscle strains, and chronic joint pain, Voltaren has become one of the first medications they reach for before considering oral pain relievers. Unlike creams that merely create a sensation of heat or cold, Voltaren actually treats inflammation at its source.

Today, Voltaren is sold over the counter throughout the United States as a 1% diclofenac sodium gel, yet many people are surprised to learn that stronger formulations exist elsewhere in the world and that prescription topical diclofenac products are available in concentrations above 1% for specific medical uses.

The Origins of Voltaren

Voltaren contains diclofenac, a member of the non-steroidal anti-inflammatory drug (NSAID) family. The drug was first developed in the early 1970s by the Swiss pharmaceutical company Ciba-Geigy, which later became part of Novartis. Researchers were seeking an anti-inflammatory medication that would rival aspirin and ibuprofen while providing stronger relief for arthritis sufferers.

The name Voltaren was introduced in Europe in 1973. For decades it was available only by prescription. In 2020, after years of clinical studies demonstrating both safety and effectiveness, the U.S. Food and Drug Administration approved Voltaren Arthritis Pain Gel as the first prescription-strength topical NSAID to become available over the counter in America.

How Voltaren Works

Unlike creams containing menthol, camphor, capsaicin or lidocaine that simply alter pain perception, Voltaren works chemically. When tissue becomes injured or arthritic, the body produces enzymes known as cyclooxygenase (COX-1 and COX-2).

These enzymes create prostaglandins, chemicals responsible for:

• pain
• inflammation
• swelling
• warmth
• stiffness

Diclofenac blocks these enzymes, reducing prostaglandin production and therefore reducing inflammation itself. In other words, most pain creams fool the nerves. Voltaren treats one of the causes of the pain.

Why It Is Different from Oral NSAIDs

Many physicians recommend Voltaren before prescribing oral anti-inflammatory medications. The reason is simple. Only a relatively small amount of the medication enters the bloodstream. Most remains concentrated in the tissues beneath the skin. Studies show systemic exposure from recommended Voltaren Gel use is dramatically lower than with oral diclofenac tablets, reducing—but not eliminating—the risk of whole-body side effects.

That makes Voltaren particularly attractive for:

• older adults
• patients with stomach sensitivity
• individuals who cannot tolerate oral NSAIDs well
• patients taking multiple medications (though interactions and precautions still matter)

What Conditions Respond Best?

Voltaren performs best where joints lie close to the surface.

Excellent candidates include:

• knees
• hands
• wrists
• ankles
• elbows
• feet

Many orthopedic physicians also recommend it for:

• tendonitis
• bursitis
• tennis elbow
• golfer's elbow
• mild sprains
• repetitive stress injuries

It is generally less effective for deep structures such as the hip or lower back because the medication cannot penetrate deeply enough to reach the affected tissues.

How Effective Is It?

Hundreds of clinical studies have evaluated topical diclofenac.

The strongest evidence is for osteoarthritis of the knees and hands, where it consistently reduces:

• pain
• morning stiffness
• swelling
• reduced mobility

Professional guidelines now recommend topical NSAIDs as a first-line treatment for knee and hand osteoarthritis, particularly in older adults or those at higher gastrointestinal risk. One important point often overlooked: Voltaren is not an instant pain reliever.

Unlike products containing menthol or lidocaine, it works by gradually reducing inflammation.

Many patients notice:

• slight improvement after several days
• better relief after one week
• maximum benefit after two to three weeks of consistent use

How Does It Compare With Other Pain Creams?

Voltaren (Diclofenac)

Best for:

• arthritis
• chronic inflammation
• tendon pain

Advantages

• Treats inflammation
• Long-lasting
• Excellent scientific evidence

Biofreeze

Works by cooling nerve endings.  Best for temporary muscle soreness. Little anti-inflammatory action.

Aspercreme Lidocaine

Blocks pain signals. Excellent for nerve-related discomfort. Does not reduce inflammation.

Tiger Balm

Uses menthol and camphor. Creates warmth and cooling sensations. Excellent temporary relief but no significant anti-inflammatory effect.

Capsaicin Cream                      

Works by gradually reducing pain nerve activity. Useful for nerve pain and some arthritis. May initially produce burning.

CBD Creams

Research remains mixed. Some users report benefit, but evidence is inconsistent and products vary widely.

Overall Ranking for Osteoarthritis

Many rheumatologists and orthopedic specialists would rank topical options roughly as follows:

1. Voltaren (Diclofenac)
2. Prescription topical NSAIDs
3. Lidocaine creams (for selected pain types)
4. Capsaicin
5. Menthol products
6. CBD creams (variable evidence)

How to Use Voltaren Correctly

Many people unknowingly reduce its effectiveness. For best results: Apply unless otherwise directed. Measure the correct amount using the dosing card included in the package. Massage gently into the affected joint until absorbed.

Allow it to dry before:

• showering
• swimming
• covering with clothing

Wash your hands afterward unless treating your hands.

Avoid using heating pads over treated skin because heat can increase drug absorption and may raise the risk of side effects.

Common Mistakes

Many users:

• stop after one day
• use too little
• skip applications
• only apply when pain becomes severe

Voltaren works best when inflammation is kept under control through regular use.

Safety Considerations

Although much safer than oral NSAIDs for many people, Voltaren is still a medication—not merely a cosmetic cream. Possible side effects include:

Skin irritation

The most common issue. Possible redness - Dryness - Itching.

NSAID Risks

Even though bloodstream levels are lower, topical diclofenac still carries warnings about:

• stomach bleeding
• kidney problems
• elevated blood pressure
• heart attack and stroke risk with prolonged NSAID use

The risk is generally lower than with oral NSAIDs but not zero.

Avoid Voltaren If You:

• are allergic to aspirin or NSAIDs
• have active stomach ulcers
• recently underwent coronary artery bypass surgery
• are in late pregnancy
• apply it to broken or infected skin

Patients taking blood thinners, other NSAIDs, certain blood pressure medicines, or with kidney disease should discuss use with their healthcare provider.

Can You Use It with Oral NSAIDs?

Generally, healthcare professionals advise against routinely combining topical diclofenac with oral NSAIDs (such as ibuprofen or naproxen) unless directed by a clinician, because doing so can increase the overall NSAID exposure and the risk of side effects.

Are Stronger Versions Available?

This is one of the most common questions.

United States

Over-the-counter Voltaren: 1% diclofenac gel

Prescription products include:

• Pennsaid 1.5% topical solution
• Pennsaid 2% topical solution (for knee osteoarthritis)
• Solaraze 3% diclofenac gel, which is approved for treating actinic keratosis (a sun-related skin condition), not arthritis pain.

Europe

Many countries sell:

• Voltaren Emulgel 2.32%

Some formulations are available without a prescription depending on local regulations.

Australia

Extra Strength Voltaren products containing approximately 2.32% diclofenac are widely available.

Canada

Some higher-strength diclofenac topical products may be available through pharmacies, with availability depending on provincial regulations and whether a prescription is required.

Does Higher Percentage Mean Better Pain Relief?

Not necessarily. A stronger concentration does not automatically produce better results.

Drug delivery depends upon:

• formulation
• penetration enhancers
• dosing frequency
• how well the medication reaches the target tissue

For example, the 2% Pennsaid solution uses a specialized formulation that allows twice-daily dosing rather than simply being "twice as strong."

The Future of Topical Anti-Inflammatories

Researchers continue developing improved topical NSAIDs designed to:

• penetrate deeper
• remain active longer
• require fewer daily applications
• minimize systemic absorption

Advances in pharmaceutical delivery systems may further improve effectiveness while maintaining a favorable safety profile.

Final Thoughts

Voltaren has transformed the treatment of arthritis and localized musculoskeletal pain by providing an evidence-based anti-inflammatory medication directly where it is needed. Unlike creams that simply mask discomfort, diclofenac reduces the inflammatory processes contributing to pain, especially in superficial joints such as the knees, hands, wrists, feet, ankles, and elbows.

For many older adults, it offers meaningful relief with less systemic exposure than oral NSAIDs, though it still requires respect for its potential risks and proper use. Used consistently and according to directions, Voltaren remains one of the best-studied and most effective topical anti-inflammatory treatments available. While higher-strength diclofenac products do exist in some countries and by prescription, they are formulated for specific purposes, and a higher percentage alone does not guarantee superior pain control.
