Effective Use of Topical Pain Creams

Effective Use of Topical Pain Creams: Guidance for Clinicians and Pharmacists

Topical pain creams — whether over-the-counter or compounded — are increasingly used for localized musculoskeletal pain, arthritis, and soft tissue discomfort. These formulations (creams, gels, ointments, lotions) can reduce pain and inflammation locally, with a lower risk of systemic side–effects compared with oral non-steroidal anti-inflammatory drugs (NSAIDs).

However, the benefits depend heavily on correct application. As prescribers or dispensers, it is essential to counsel patients on best practices for application, frequency, and precautions.

Why Topical Pain Creams and When They Are Useful

• Localized delivery with fewer systemic risks: Topical NSAIDs (e.g., gels or diclofenac-based creams) are a good option when pain is confined to a few joints or muscle groups. This strategy can help avoid the gastrointestinal, cardiovascular, or renal risks associated with systemic NSAIDs.
• Suitability for a wide range of conditions: Topical analgesics are useful for osteoarthritis, tendonitis, muscle sprains/strains, localized soft tissue pain, and other joint or musculoskeletal conditions.
• Alternative or adjunct to systemic therapy: For patients who cannot tolerate oral NSAIDs (due to GI, renal, or cardiovascular risk), topical therapy offers a viable alternative to manage pain with fewer systemic exposures.

Best Practices for Application — What to Tell Patients

When recommending or dispensing a topical pain cream, advise patients to follow these practical steps and precautions:

1. Apply only to clean, dry, intact skin.
   Before application, the skin should be washed and dried. Avoid applying to broken, irritated, or inflamed skin.
2. Use a thin, even layer — and rub it in gently but thoroughly.
   For gels and creams, moderate rubbing helps ensure absorption. This can be counselled as “rub in well for about 2-4 minutes”.
3. Wash hands after application.
   Unless the hands themselves are being treated, patients should wash their hands thoroughly after applying the cream to avoid accidentally spreading it to eyes, mucous membranes, or other skin areas. This also avoids transfer to other people or animals.
4. Avoid occlusion, tight bandaging, or concurrent heat application.
   Patients should not apply a tight bandage, heating pad, or other sources of heat over the treated area — that can increase absorption and raise the risk of local or systemic side-effects. Heat can also increase the risk of skin irritation, rash or blistering.
   Similarly, avoid covering the area until the product has dried, and avoid applying other topical agents or cosmetics over the same spot.
5. Observe dosing too frequency and total area limits.
   Many over-the-counter topical NSAIDs or analgesics are recommended 2–4 times a day, depending on product and indication.
   Also counsel patients to avoid applying to large or multiple wide areas — topicals are most appropriate when pain is localized. Counselling on the proper areas (i.e. C2-C3 area of spine) is important to ensure patients are applying the product to the proper area to receive the intended effect.
6. Set patient expectations about onset of relief.
   While some pain relief may be felt quickly, full benefit — especially for NSAID gels — may take days of regular use. For example, relief from a topical NSAID gel might take up to a week to have the full intended effect.  If no improvement occurs, or if skin irritation develops, patients should seek support to re-evaluate their treatment plan.

Special Considerations & Safety Warnings

• Compounded topical creams may carry additional risks. For example, some compounded pain creams use excipients like dimethyl sulfoxide (DMSO) to enhance penetration. While this may improve drug delivery, DMSO can also increase absorption — possibly of other chemicals — potentially raising safety concerns, especially if patients apply additional products or ointments over the same area.
• Topical therapy is not always ideal for widespread pain or systemic conditions. Given the localized delivery, topicals usually work best for a limited number of joints or a confined region rather than diffuse or systemic pain.
• Monitor for skin reactions: Even though topical analgesics often avoid systemic side-effects, local irritation (redness, burning, itching) can occur.
• Transfer risks: A small but important consideration in the use of topical pain creams is the risk of unintentional transfer to others, particularly young children, and to pets. Because many compounded formulations are designed to enhance skin absorption, residual product on the skin or hands can transfer through touch, especially within the first 30–60 minutes after application.
• Pet Safety: Pets — especially dogs and cats — may be at risk if they lick the area where a topical has been applied, or if the patient pets them before washing their hands. Because many compounded analgesics may contain NSAIDs, anesthetics, anticonvulsants, or other systemic drugs that are unsafe or even toxic to animals at low doses. If a pet ingests even a small amount of topical medication, owners should immediately contact a veterinarian or poison control, as systemic toxicity can develop quickly.
