Aspercreme's Varying Ingredients and Contraindications
Aspercreme is a brand name for a variety of topical pain relief products, and the specific contraindications depend heavily on the active ingredient. While the original formula contains trolamine salicylate, other versions feature lidocaine, diclofenac, or capsaicin. Each of these active ingredients has unique risks and requires different precautions.
Salicylate-Based Aspercreme (Original)
The active ingredient in the original Aspercreme formula, trolamine salicylate, is a topical salicylate related to aspirin. Due to this, the following individuals should avoid using it:
- Individuals with an aspirin or salicylate allergy: Anyone with a known allergy to aspirin or other salicylates should not use this product, as it can cause a severe allergic reaction. Symptoms may include rash, hives, swelling, or difficulty breathing.
- Children and teenagers: The Centers for Disease Control (CDC) and healthcare professionals advise against giving aspirin or salicylate-containing products to children and teenagers, especially during or after a viral illness like chickenpox or the flu. This is because it is associated with an increased risk of Reye's syndrome, a rare but serious illness affecting the liver and brain.
- Pregnant individuals: It is generally recommended to avoid topical salicylates during pregnancy, particularly from 20 weeks onward, as it may harm the unborn baby.
- Individuals with certain health conditions: Those with a history of heart disease, kidney disease, or stomach problems like ulcers should be cautious, especially when applying over large areas, as systemic absorption can occur.
Lidocaine-Based Aspercreme (Maximum Strength)
For products containing lidocaine, a topical anesthetic, the following contraindications apply:
- Individuals with a lidocaine or amide-type anesthetic allergy: Those allergic to lidocaine or similar anesthetics (like bupivacaine) should not use these products.
- Patients with specific medical conditions: Use with caution in individuals with heart, liver, or kidney disease, as excessive systemic absorption of lidocaine can cause severe cardiovascular effects or seizures.
- Application on broken or damaged skin: Do not apply lidocaine-based Aspercreme to open wounds, infected skin, or burns, as this increases the risk of systemic absorption and serious side effects.
- Children: Topical lidocaine products are not recommended for teething infants or young children due to the risk of accidental ingestion and systemic toxicity.
Diclofenac-Based Aspercreme (Arthritis Pain)
Aspercreme Arthritis Pain Gel contains diclofenac, a topical non-steroidal anti-inflammatory drug (NSAID) with significant warnings. Individuals should avoid this formulation if they:
- Have an aspirin or NSAID allergy: A severe allergic reaction, including asthma-like symptoms, is a major risk for those with this type of allergy.
- Are about to undergo heart bypass surgery: Do not use this NSAID-containing product immediately before or after coronary artery bypass graft (CABG) surgery, as it can increase the risk of a fatal heart attack or stroke.
- Have a history of certain health issues: Conditions like heart disease, high blood pressure, ulcers, bleeding problems, liver or kidney disease increase the risk of serious side effects, such as stomach bleeding or heart attack.
- Are in the later stages of pregnancy: Diclofenac is not recommended for use after 30 weeks of pregnancy due to risks to the unborn child.
Capsaicin-Based Aspercreme (Warming Pain Relief)
Capsaicin products, derived from chili peppers, are for external use only and have a different set of precautions. Individuals should not use them if:
- Under the age of 18: Many capsaicin products are not recommended for individuals under 18 years of age.
- Applying to broken or sensitive skin: Do not use on damaged, burned, or irritated skin, as it can cause severe pain or irritation.
- Using with heat: Never apply this product with a heating pad, as it can increase the burning sensation and the risk of burns.

General Precautions for All Aspercreme Products
Regardless of the active ingredient, certain universal precautions apply when using any Aspercreme product:
- Do not apply to damaged skin: Never use Aspercreme on wounds, broken skin, burns, or infected areas. This increases the risk of systemic absorption and adverse effects.

- Consult a doctor: If you have any serious underlying health conditions, are pregnant or nursing, or are considering using Aspercreme on a child, talk to a healthcare professional first.
When to Seek Medical Advice
Stop using Aspercreme and seek medical help if you experience any serious side effects, which can vary depending on the active ingredient. For all formulations, severe allergic reactions like swelling of the face, tongue, or throat, or difficulty breathing, require immediate medical attention. Other warning signs include:
- Salicylate products: Ringing in the ears, nausea, or vomiting.
- Lidocaine products: Dizziness, seizures, or irregular heartbeat.
- Diclofenac products: Signs of stomach bleeding (black, bloody stools), chest pain, or symptoms of heart failure (swelling ankles).
- Capsaicin products: Severe burning, pain, or blistering of the skin.
