The only active ingredient in Blue Emu analgesic cream is trolamine salicylate, according to Blue Emu. Trolamine salicylate is a topical analgesic, or pain reliever. With topical application, this ingredient temporarily relieves pain by reducing swelling in the muscles and joints, states Drugs.com.
Trolamine salicylate has no common side effects and carries little risk of interacting with other medications or conditions when individuals use it externally and as directed, states Drugs.com. The cream should not come in contact with the eyes, mouth or nose or any areas of broken skin. The risk of an allergic reaction to trolamine salicylate increases in those with aspirin or salicylate allergies. Symptoms of an allergic reaction that require immediate medical attention include rash, difficulty breathing, swelling of the face, and skin irritation. No studies exist regarding the effects of trolamine salicylate on children as of 2015, so users should consult a health care professional before using Blue Emu analgesic cream with children under 12.
While trolamine salicylate is the only active ingredient in Blue Emu analgesic cream, inactive ingredients include aloe and emu oil among others, notes Blue Emu. The inactive status of these ingredients means that they do not increase or affect the pain-relieving component of the product, states Drugs.com.
