A Guide For Choosing An Appropriate NSAID
Due to the increasing rise in drug abuse from opioids and recent safety warnings regarding NSAIDs, practitioners are beginning to show more interest in topical agents.
Due to the increasing rise in drug abuse from opioids and recent safety warnings regarding nonsteroidal antiinflammatory drugs, or NSAIDs, practitioners are beginning to show more interest in topical agents.
There are several factors that should be considered prior to using a topical agent. Some factors include pain type, duration, skin sensitivity, and allergies.
One major advantage to topical pain relief is the local delivery system as well as a significant decrease in systemic side effects.
The chart below offers a guide on how to recommend topical pain relief to different patient populations. Always remember to counsel patients on proper use and review clinical pearls.
Diclofenac/ compounds (ketoprofen, ibuprofen, piroxicam, etc) 1,2,3,4,5
Lower risk of systemic effects compared to PO NSAIDS (in particular GI effects)
Evidence that these are equivalent to PO forms for treating osteoarthritis and acute musculoskeletal pain
Increased risk of dermatologic effects
More expensive than PO NSAIDs
Useful for localized pain or if there is a concern for systemic effects
Pennasaid and Voltaren are FDA approved for osteoarthritis
Flector is approved for acute sprains
Do not combine topicals and PO NSAIDs
DMSO used in diclofenac solution improves absorption
Lidocaine patches 7,8
Potentially beneficial for neuropathic pain
Very low blood levels equates to few systemic effects
Limited evidence in efficacy for neuropathic pain
Skin irritant in patients w/ sensitive skin
Potential toxicity/death if not properly counseled
1st line treatment in patients who cannot tolerate PO meds
1st line treatment in patients who have concerning systemic reactions
5% patch is FDA approved and is RX only
4% patch is OTC w/ variable dosing
Capsaicin 2, 6
Potentially useful in osteoarthritis and rheumatoid arthritis
Useful in postherpetic neuralgia and HIV neuropathy
Rare systemic effects
Local skin reactions/irritation can occur
Requires multiple applications per day
Counsel patients it can take up to 2-4 weeks to take full effect
Start with a low dose and titrate up due to tolerability
counsel patients to wash their hands after applying. Avoid using a heating pad concurrently
Menthol, camphor, Bengay, Icy Hot, etc 2,9
Beneficial for short term mild pain
Not for chronic or acute conditions
Topical salicylates are not effective for osteoarthritis
Counsel patients to wash their hands after applying
Other agents- TENS units/ kinesology tape 10,11
TENS units and tape are considered safe
Limited quality evidence is available for tape
Occasional reports of local irritation or allergic reactions to tape
Inconclusive and conflicting evidence for TENS units
Counsel patients not to use either product on broken skin
