camphor, lidocaine, and methyl salicylate contains methyl salicylate, which is an NSAID. Using an NSAID can increase your chances of having a fatal heart attack or stroke, especially if you use it for a long time or if you have heart disease. Even people without heart disease or risk factors could experience a stroke or heart attack while using an NSAID.

Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG).

An NSAID may also lead to stomach or intestinal bleeding, which can be fatal. These issues can happen without warning while you are using an NSAID, especially in older adults.
