Transanosil is a brand-name topical pain relief lotion classified as a topical rubefacient. It contains three active ingredients: capsaicin (0.025%), menthol (10%), and methyl salicylate (30%). It is used for the temporary relief of minor aches and pains of muscles and joints associated with arthritis, simple backache, strains, sprains, muscle soreness and stiffness, and bruises.
Other brand names with the same generic formula include Dendracin Neurodendraxcin, Ultracin, Xoten-C, New Terocin, Exoten-C Pain Relief, and Bio-Therm Pain Relieving Lotion. Transanosil is not a controlled substance and is approved for use in adults and children 12 years and older.
Transanosil is available both over the counter (OTC) for standard formulations and by prescription for specific or compounded versions. It works by creating warming and cooling sensations on the skin that compete with and override pain signals — a mechanism known as counterirritant analgesia.

Transanosil works through three simultaneous mechanisms — one for each active ingredient. Capsaicin (0.025%) activates TRPV1 receptors in skin nerve endings, initially producing warmth and then progressively depleting substance P from local nociceptors. With repeated use, this desensitizes nerve endings to ongoing pain signals. The initial burning sensation decreases within 1-2 weeks of consistent application.
Menthol (10%) activates TRPM8 cold receptors in the skin, producing a cooling counterirritant sensation that competes with pain signals via gate control mechanisms. Methyl salicylate (30%) — a salicylate ester related to aspirin — provides both a warming counterirritant effect and mild anti-inflammatory activity through limited percutaneous absorption.
Together, these three ingredients target multiple pain pathways simultaneously. The warming and cooling sensations are felt within minutes of application; the deeper desensitization effect from capsaicin develops over 1-2 weeks of regular use. This is why consistent, frequent application (up to 4 times daily) produces the best long-term results.

Apply a thin layer to affected area up to 4 times daily. For ages 12 and older.
Transanosil is not on the FDA's official drug shortage list as of 2026 and there is no known national manufacturing disruption. However, as a brand-name niche topical rubefacient, it is not consistently stocked at all pharmacy locations. Patients in smaller markets or rural areas may find it less reliably available than generic topical analgesics or well-known brands like Icy Hot or Bengay.
Availability is highest at larger chain pharmacies (CVS, Walgreens, Walmart Pharmacy) in metro areas. Grocery store pharmacies (Kroger, HEB) and specialty compounding pharmacies are also good options. For ongoing prescriptions, mail-order pharmacy ensures more consistent supply.
Rather than calling multiple pharmacies yourself, medfinder calls local pharmacies on your behalf to check stock and texts you the results — saving you time and frustration.
Because Transanosil is not a controlled substance, any licensed prescriber in the United States can write a prescription for it without special DEA registration or state controlled substance authorization. Many standard formulations are also available without any prescription as OTC products.
Primary care physicians (PCPs) and family medicine doctors
Rheumatologists (arthritis and joint disease specialists)
Orthopedic surgeons and sports medicine physicians
Physiatrists (physical medicine and rehabilitation)
Nurse practitioners (NPs) and physician assistants (PAs)
Telehealth providers can prescribe Transanosil during a standard online visit. Platforms like Teladoc, MDLive, Amazon Clinic, and GoodRx Care can issue same-day prescriptions for muscle and joint pain without an in-person visit. This is especially convenient for patients who need a prescription version for insurance reimbursement or FSA/HSA purposes.
No. Transanosil is not a controlled substance. It has no DEA schedule, no abuse or dependence potential, and no special dispensing restrictions. Any licensed prescriber — including physicians, nurse practitioners, and physician assistants — can write a prescription for Transanosil without a DEA registration or special authorization.
Because Transanosil is not a controlled substance, it can also be prescribed via telehealth without any additional requirements. Many standard formulations are also available over the counter without any prescription at all. There are no quantity limits or refill restrictions imposed by federal law for this medication.
Most side effects of Transanosil are mild, localized to the skin at the application site, and resolve with continued use. Common side effects include:
Burning or stinging sensation at the application site (most common; decreases with regular use)
Skin warmth, redness, or flushing
Mild tingling or itching
Skin dryness or sensitivity with frequent use
Severe or persistent burning not improving after several days
Skin blistering, peeling, or open sores at application site
Signs of allergic reaction: hives, rash, swelling of face, lips, or throat, difficulty breathing
Unusual bruising or bleeding (especially in patients on warfarin or other blood thinners)
Pain that worsens or does not improve after 7 days of use

Warfarin (Coumadin)
moderateMethyl salicylate from Transanosil can be absorbed through the skin and potentiate warfarin's anticoagulation, increasing INR and bleeding risk. Monitor INR closely if concurrent use is unavoidable.
Apixaban (Eliquis), Rivaroxaban (Xarelto), Dabigatran (Pradaxa)
moderateTheoretical increased bleeding risk with DOACs due to salicylate absorption. Use with caution and inform all providers.
Oral NSAIDs (ibuprofen, naproxen, aspirin)
minorAdditive salicylate effect possible with large-area or frequent application. Generally low concern with standard localized use; monitor for increased GI or bleeding effects.
Other topical pain medications
minorAvoid applying to same area as other topical analgesics or medicated patches. Safety of concurrent topical pain medications is not well-established.
Transanosil is a well-established topical rubefacient that provides effective, localized relief for minor muscle and joint pain through a triple-action counterirritant formula. Its combination of capsaicin, menthol, and methyl salicylate offers a multi-pathway approach to pain relief with a low risk of systemic side effects when used as directed.
The primary patient challenges with Transanosil are inconsistent pharmacy stocking and awareness of the warfarin interaction. Prescribing generically, knowing equivalent brands, and using GoodRx for cost savings addresses most access and cost barriers. For patients on blood thinners, always counsel them about the methyl salicylate interaction before starting.
