If you have joint pain and want to avoid oral pain medications, a topical pain reliever may be a good option. Topical pain relievers are applied to the skin over the painful area and tend to have fewer side effects than oral medications.
Over-the-counter topical pain relievers fall into a few general categories: counterirritants, salicylates, capsaicin, and anesthetics, as well as the newer CBD topicals. How do you know which type is best for you? This guide describes each type, including how it works and potential pros and cons.
Sold under brand names such as Icy Hot, Tiger Balm, BioFreeze, and Gold Bond, counterirritants work by creating temporary hot or cold sensations that distract the brain and interrupt pain signals. Examples of counterirritant active ingredients include menthol, eucalyptus, camphor, and wintergreen.
Pros: The natural ingredients in counterirritants are typically safe and may cause only minor side effects, like skin irritation.
Cons: Counterirritants can produce a strong odor.
Sold under brand names such as Aspercreme and Sportscreme, salicylates work by delivering a small dose of anti-inflammatory medication that’s chemically similar to aspirin. Some topical products, like Bengay or Thera-gesic, are a combination of salicylates and counterirritants.

Pros: Salicylates can temporarily reduce acute pain and are odor-free.
Cons: Salicylates can cause drug interactions with medications such as blood-thinners. If you are sensitive to aspirin or take a medication that may interact with aspirin, talk with your doctor before using a salicylate.
Developed from chili peppers, capsaicin creates a burning sensation. Many experts also believe that capsaicin stimulates the release of a chemical in the body called “substance P,” which is involved in pain signals in the nervous system. After releasing substance P there is less of it available, so pain signals become less frequent.
Capsaicin products are sold under brand names such as Capzasin and Zostrix. Capsaicin cream can also be made at home.
Pros: Capsaicin can be effective even on deeper joints below the skin, such as back, hips, and shoulders. It also has low side effect risks.
Cons: It may take a couple of weeks of daily use before experiencing results. Also, the burning sensation may be too intense for some people, so you should try it on a small area first. It needs to be applied while wearing gloves, and hands should be washed afterward. Avoid contact with your eyes and mouth.
Also, capsaicin can lose its effectiveness over time due to damage to the nerve tissues.
A numbing and desensitizing agent, lidocaine “mutes” pain signals. It is sold under product names such as Salonpas patches, Aspercreme with Lidocaine, and Icy hot with Lidocaine.
Pros: Lidocaine is an effective anesthetic for arthritis and musculoskeletal pain and is available in both over-the-counter and prescription strengths.
Cons: Overuse can lead to serious side effects such as irregular heartbeat, so it’s important to follow manufacturer’s instructions.
Also, lidocaine should not be used in combination with heat packs or cold compresses. The numbing action of lidocaine diminishes your sense of hot and cold, which can result in accidental burns or damaged skin.
Cannabidiol, commonly referred to as CBD, is the non-psychoactive component of marijuana and a relatively new addition to over-the-counter pain reliever products. CBD-infused creams and gels are absorbed by the skin, and limited research suggests they may reduce inflammatory and neuropathic pain.1,2,3
Pros: CBD topicals are an alternative for people who want to avoid NSAIDs altogether or who don’t like the numbing and heat sensations of other topicals. Also, some research suggests that CBD can also help reduce anxiety and improve sleep,4,5 two problems that are often associated with chronic arthritis pain.
Cons: CBD products tend to carry a bigger price tag than other topicals. Also, depending on where you live, there may still be a stigma associated with these products even though they contain only a negligible amount of THC and do not produce a “high.”
Other Topical Products
There are a few other topical products worth mentioning that do not necessarily fit into the above categories. One is emu oil products, such as Australian Dream and Blue Emu. Emu oil products may help reduce pain and inflammation,6,7 particularly if they also contain curcumin.8,9
Another alternative is arnica-containing topical products. Arnica is an herb in the sunflower family whose flowers are used medicinally for stiffness and pain relief.10,11 It is sold under various names, including Topricin and Arnicare.
These products are less commonly used than the others listed above, and have limited research in humans to support them.
In addition to these over-the-counter options, certain topical pain medications are available with a prescription, including topical NSAIDs like Voltaren (diclofenac) and prescription-strength lidocaine patches (Lidoderm).
Overall, topical pain relievers are a great option for those who experience intermittent pain in their joints because of conditions such as osteoarthritis, rheumatoid arthritis, and bursitis. Follow a manufacturer’s instructions to use them safely and effectively.
