Indications

Fungal Infection

Tolnaftate is used to treat fungal skin infections such as athlete's foot, jock itch, and ringworm. It works as an antifungal by stopping the fungus from growing further.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Tolnaftate is an antifungal medicine that works by damaging the hyphae (thread-like filaments) of fungi and blocking their mycelial growth. This action makes it effective against dermatophytes such as Epidermophyton, Microsporum, and Trichophyton species, as well as against Malassezia furfur. It does not work against Candida species or bacteria.

Pregnancy & Breastfeeding

Tolnaftate cream or powder has not been given an official FDA pregnancy category. No animal studies on it have been reported, and there is no controlled research in pregnant women. Because of this, doctors generally advise using topical tolnaftate during pregnancy only when the expected benefit justifies the possible risk. It is likewise unknown whether tolnaftate passes into human breast milk.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Dosage Reference

⚠️ Reference ranges from official sources only. Consult your doctor for personalized dosing.

Adults: Use tolnaftate on the skin only. Clean the area first and dry it thoroughly. Then apply the medicine to the affected skin, usually twice a day, or as directed on the product package or by your doctor. How much you use and how long you use it depends on the type of infection being treated. Some forms of tolnaftate, such as powder, need to be shaken before applying. Check your product package to see whether yours is one of them. Apply enough to cover the affected area and a little of the surrounding skin. Wash your hands afterwards. Do not wrap, cover or bandage the area unless your doctor tells you to. Use tolnaftate regularly so you get the most benefit from it, and try to apply it at the same time(s) each day. Continue to use it until the full prescribed amount is finished, even if the symptoms disappear after you start. If you stop too early, the fungus may continue to grow and the infection may come back (relapse). Inform your doctor if your condition persists after 2 weeks of treatment for jock itch, or after 4 weeks of treatment for athlete's foot or ringworm. Also inform your doctor if your condition worsens at any time.
