What the AI looks for in Joint & Muscle Pain Relief
- Active ingredient type
- Diclofenac (topical NSAID) for arthritis. Menthol or camphor (counterirritant) for muscle soreness. Lidocaine (anesthetic) for numbing. Only the NSAID treats inflammation. Counterirritants and anesthetics mask the pain and do not treat it.
- Diclofenac strength
- 1% diclofenac sodium is the OTC strength. Higher-strength diclofenac products are prescription only, so 1% is what you should look for OTC.
- Lidocaine strength
- 4% is the maximum OTC concentration. Products with less lidocaine numb less well.
- Joint depth
- Topical NSAIDs work best on superficial joints such as the hands, wrists, knees, elbows and feet. Not enough of the drug reaches the hips or the spine to help much.
- Duration of use
- Diclofenac gel is labeled for up to 21 days without a doctor's advice. Pain that lasts longer than that should be evaluated by a doctor.
Brands that matter
- Voltaren: The original OTC diclofenac 1% gel. Store-brand diclofenac 1% contains the same drug.
- Biofreeze: Menthol cooling gels, rolls-on and sprays that physical therapists commonly use.
- Salonpas: Patches with methyl salicylate and menthol, plus lidocaine versions.
- Aspercreme: Lidocaine creams and patches, plus a trolamine salicylate cream with no odor.
- Bengay: Classic menthol and methyl salicylate creams.
- Tiger Balm: Balm with camphor and menthol, for strong counterirritant relief.
What to avoid
- Using a topical NSAID at the same time as an oral NSAID unless a doctor approves it.
- Covering a heat or menthol product with a heating pad or a tight bandage, because this can cause burns.
- Applying any of these products to broken or irritated skin.
- Products with homeopathic or vague 'proprietary blend' claims and no listed active drug.
Questions
Is store-brand diclofenac gel the same as Voltaren?
Yes, if it is labeled diclofenac sodium topical gel 1%. It has the same active ingredient at the same strength.
Why does Voltaren take days to work?
Diclofenac gel builds its effect over regular use, usually up to 4 times daily. It is not an instant numbing or cooling product.
