Camphor/menthol /methyl salicylate topical products come in many different formulations, such as patches, creams, gels, and oils. The three active ingredients in the products are analgesics that temporarily relieve minor muscle aches and pain. This medication is applied onto the skin many times throughout the day, usually no more than 3 or 4 times per day. These topical products are available over the counter (OTC) as brand-name or generic medications. They don't typically cause many side effects but can sometimes irritate the skin.
Short-term relief of minor aches and pains in the muscles and joints caused by:
Camphor, menthol, and methyl salicylate are analgesics. More specifically, they work as counter-irritants. When they're applied to the skin, the active ingredients turn on pain sensors on the skin, which makes the area feel warm or cold. This makes the pain sensors less sensitive to pain signals, which helps to relieve pain.

Tips for camphor/menthol /methyl salicylate patches:
Camphor/menthol /methyl salicylate is for short-term relief of minor aches and pains in the muscles and joints. You can use this medication every day for a week. But if your symptoms last more than a week or if they come back after a few days, you should talk to a healthcare professional before you continue using camphor/menthol /methyl salicylate. They can see whether there's something else going on that could need other treatment.
Check with your healthcare team first before you apply camphor/menthol /methyl salicylate onto sensitive skin. Camphor/menthol /methyl salicylate products can sometimes irritate the skin. In general, it's not a good idea to apply the medication to wounded, irritated, or damaged skin. Talk to a healthcare professional about other options for pain relief if your skin gets irritated easily from topical products.
No, don't use camphor/menthol /methyl salicylate if it's expired. Always check the expiration date of your medication before you use it. Expired camphor/menthol /methyl salicylate might not work well to provide pain relief. Throw away the medication if it's expired and get a new one over the counter.
Don't use camphor/menthol /methyl salicylate during pregnancy without talking to a healthcare professional or obstetrician-gynecologist (OB-GYN). This combination medication contains three active ingredients. Menthol and camphor are considered safe during pregnancy. But there's not enough research on whether the methyl salicylate ingredient is safe to use while pregnant. If you have back pain during pregnancy, consider wearing supportive clothes or using a heating pad or a cold pack to help. Ask a healthcare professional or OB-GYN about safe options for pain relief during pregnancy.
Make sure to read the manufacturer's instructions for your camphor/menthol /methyl salicylate product before you apply it. Some products give specific timing instructions. For example, the directions for Coralite Pain Relieving Patches say that you need to take the patch off at least 1 hour before a shower or bath. The instructions for Coralite Pain Relieving Patches also say that you shouldn't apply them right after showering or bathing.
No. You shouldn't cut a camphor/menthol /methyl salicylate patch to fit a particular area of your body. This can change the way the medication gets released from the patch. You can find camphor/menthol /methyl salicylate patches in various sizes, so try to choose one that will best fit the area you're treating. Ask a healthcare professional if you need help finding a patch size that's right for you.
Don't leave a camphor/menthol /methyl salicylate patch on the skin longer than what the directions say to. Leaving the patch on for too long can cause skin irritation. Keep in mind that the amount of time you can leave a patch on the skin can vary for different manufacturers and brand names. This is because each product can contain different amounts of the active ingredients. Ask a healthcare professional if you have more questions about how long to keep a patch on.
Ask a healthcare professional about using ice packs with camphor/menthol /methyl salicylate. Ice packs cause a direct temperature drop on the skin, which causes blood flow in the area to slow down. This helps lessen pain and inflammation (swelling). It's thought that menthol can turn on nerve signals that sense temperature changes in the body, which can sometimes have a similar effect as ice. A small clinical study suggested that applying ice and menthol topical gel to the same affected area can have a combined effect of slowing down blood flow. This might help lessen inflammation and minor aches and pain. Use ice packs on the skin for only short periods of time to prevent skin burn. Menthol-containing products have a possible risk for serious skin burns as well.
Camphor/menthol /methyl salicylate can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Although rare, methyl salicylate (one of the active ingredients components of the camphor/menthol /methyl salicylate products) can cause salicylate toxicity. This happens when your body absorbs too much of the medication. The risk for salicylate toxicity appears mostly with overusing the product or accidentally ingesting it. Salicylate toxicity is a serious side effect that should be treated right away.
Keep camphor/menthol /methyl salicylate topical products out of reach from children and pets. Get medical help right away if you experience nausea, vomiting, fast breathing, shortness of breath, ringing in the ears, headache, dizziness, confusion. These can be signs of salicylate toxicity.
Camphor/menthol /methyl salicylate topical products can rarely cause serious skin burns. These skin burns are possible even when you use the topical product for the first time. Severe burning or blistering can happen within 24 hours of the first use. Sometimes, it can be so severe that you might need to be hospitalized.
Don't apply camphor/menthol /methyl salicylate onto any broken or irritated skin. Never place tight bandages around the treated area. And don't place any heating pads on top of the area where you applied camphor/menthol /methyl salicylate. This can raise the risk for serious burns.
Stop using the camphor/menthol /methyl salicylate topical product and get medical help right away if you experience pain, blistering, or swelling where you applied the medication.
There are many different camphor/menthol /methyl salicylate topical products that come in different forms and under many different brand names. They can contain different amounts of each active ingredient.
