Terbinafine HCl - Overview
Terbinafine is an antifungal medication used in the treatment of nail fungus and other fungal conditions. People in need of a terbinafine prescription can connect with a licensed medical provider through Push Health who can prescribe the medication to a patient's pharmacy when appropriate to do so.
What Is Terbinafine Used For?
Terbinafine, sometimes marketed under the brand name Lamisil, is used in the treatment of various conditions:
Oral tablets (prescription required):
- Toenail fungus (typical course about 12 weeks)
- Fingernail fungus (typical course about 6 weeks)
- Selected tinea infections of the scalp or skin
Topical creams are available over the counter or with a prescription) and are frequently used to treat athlete's foot, jock itch, and ringworm. Topical terbinafine alone is rarely used to treat nail fungus.
Terbinafine belongs to a class of medications known as allylamine antifungal agents and is thought to work by blocking sterol synthesis which weakens the fungi cell membrane.
Terbinafine - Dosage and Cost
Terbinafine 250 mg tablets are often administered once daily for six to twelve weeks when used in treating nail fungus. Visible clearing of the nail can take 6-12 months after finishing the tablets, especially for big toenails. New, clear growth at the cuticle is an early sign of response. Terbinafine tablets should generally be stored away from light at 25° C in a tight container.
Generic 250 mg tablets are usually inexpensive, often costing under $0.40 cents each. Insurance coverage and prescription discount cards may help reduce cost further.

Terbinafine - Frequently Asked Questions
Is terbinafine the same as Lamisil?
Yes. Lamisil is the brand name. Generic tablets contain the same active ingredient and cost less.
Do I need a prescription for terbinafine?
It depends on the form. Some cream versions are available over the counter.
How long until my toenails look normal?
Tablets are often prescribed to be taken for 12 weeks but the nail may not look fully clear until it grows out over many months.
Can terbinafine affect my liver?
Serious liver injury is uncommon but has been reported. People with existing liver disease generally should avoid the medication. Avoid heavy alcohol use and report any symptoms.
Why does terbinafine affect my taste?
Taste and smell changes can occur and usually improve after stopping the medication. Discuss any concerns with your medical provider.
What should I avoid while taking terbinafine?
Heavy alcohol use should be avoided. Some medications such as antidepressants, beta blockers, and other CYP2D6-metabolized drugs can interact with terbinafine. Caffeine effects may be enhanced while taking the medication.
Is there an alternative to terbinafine for toenail fungus?
Yes. Oral itraconazole (Sporanox) is the main alternative. Fluconazole is sometimes prescribed off-label. Topical lacquers such as ciclopirox (Penlac) nail lacquer and efinaconazole (Jublia) are also sometimes prescribed when oral therapy is not appropriate.
How much does terbinafine cost?
Generic tablets typically cost under 40 cents each at most pharmacies. Prescription savings cards and insurance coverage may help reduce out-of-pocket costs even further.
