Terbinafine hydrochloride cream is a drug that is more commonly used clinically for the treatment of epidermal fungal infections, and is often used in the treatment of conditions such as ringworm and tinea pedis. As a topical medication, the adverse effects of this medication are generally minor, but it may cause some local irritation or allergy. If you experience localized tingling, redness, swelling, or blistering after using the medication, you should stop using the medication immediately and go to the clinic that prescribed it for a follow-up visit. If the symptoms are not completely relieved after two weeks, a follow-up visit is required to adjust the medication.
