Zostrix vs Voltaren vs Thera-Gesic: Which Pain Cream Works Best?
When comparing topical pain relief creams, the matchup of Zostrix vs Voltaren vs Thera-Gesic highlights three different approaches. Zostrix uses capsaicin to calm overactive nerves and is often chosen for neuropathy and shingles pain. Voltaren contains diclofenac, a nonsteroidal anti-inflammatory drug for arthritis-related inflammation in joints. Thera-Gesic combines menthol and methyl salicylate, a counterirritant blend that provides cooling and warming relief for sore muscles and back pain. In this guide, we compare how each cream works, the pain types each fits best, and where to find lower-cost generic alternatives.
1. Thera-Gesic Pain Relief Cream
Active Ingredients: Menthol and Methyl Salicylate
For availability updates and generic options, see our Thera-Gesic Discontinued Alternatives guide.
How It Works: Thera-Gesic combines menthol for a cooling sensation with methyl salicylate, a topical analgesic and counterirritant that helps interrupt pain signals. This dual-action formula targets surface-level muscle and joint pain.
Best For: Temporary relief of minor aches and pains including muscle strains, back pain, arthritis discomfort, and overuse injuries.
2. Zostrix Cream (Capsaicin 0.025%)
Active Ingredient: Capsaicin 0.025%
For a full breakdown of affordable alternatives with the same active ingredient, see our Zostrix Generic Alternatives guide.
How It Works: Zostrix uses capsaicin to gradually desensitize peripheral nerve endings in the skin, reducing how strongly pain signals are transmitted. Consistent use is important, as benefits build over time.
Best For: Ongoing relief of nerve pain such as postherpetic neuralgia (shingles pain), diabetic neuropathy, and peripheral neuropathy.
Note: The original Zostrix 0.025% generic is currently unavailable. The Rugby Arthritis Pain Relieving Cream 0.075% is in stock and offers a stronger alternative for nerve pain relief.
3. Voltaren Topical Gel (Diclofenac 1% NSAID)
Active Ingredient: Diclofenac Sodium 1%
For a full breakdown of lower-cost options that match Voltaren relief, see our Voltaren Generic Alternatives guide.
How It Works: Voltaren contains diclofenac, a nonsteroidal anti-inflammatory drug that reduces inflammation at the source of pain. It blocks prostaglandins that drive swelling and discomfort to deliver targeted relief without the stomach concerns that can occur with oral NSAIDs.
Best For: Relief of arthritis pain in the knees, hands, elbows, and other small joints. A good choice for osteoarthritis, rheumatoid arthritis, or chronic joint stiffness.

FAQs
What’s the difference between Zostrix and Zostrix HP?
Zostrix contains 0.025% capsaicin, while Zostrix HP is the high-potency version with 0.075% capsaicin. Both relieve nerve-related pain, but Zostrix HP is typically used for more persistent or severe cases like postherpetic neuralgia.
Is Voltaren the best cream for arthritis?
Voltaren (diclofenac sodium 1%) is one of the most widely recommended OTC topical treatments for arthritis. It’s an NSAID that directly reduces inflammation in joints, especially knees, hands, and elbows.
Can I use Voltaren and capsaicin cream together?
You can use both, but not at the same time or on the same area. Voltaren reduces inflammation, while capsaicin helps dull nerve pain. If combining, use them on different areas or alternate them based on your doctor’s guidance.
Is Thera-Gesic good for back pain?
Yes. Thera-Gesic combines menthol and methyl salicylate to provide fast-acting relief for sore backs, strained muscles, and general aches. The Rugby Pain Relieving Cream is a generic equivalent and offers the same dual-action formula at a lower cost.
Can I use Zostrix for shingles pain?
Yes. Zostrix is often recommended for post-shingles nerve pain (postherpetic neuralgia). Capsaicin helps reduce the intensity of pain signals by depleting substance P, a chemical that transmits pain to the brain.
Which of these creams is available over the counter?
All of them — including Voltaren, Zostrix, Zostrix HP, and Thera-Gesic — are available OTC. Affordable generic versions like Rugby Capsaicin Cream, Rugby Diclofenac Gel, and Rugby Pain Relieving Cream are also sold without a prescription.
