Herperax Ointment contains Acyclovir 5% w/w, an antiviral agent indicated for the topical treatment of herpes simplex virus infections, including cold sores (herpes labialis) and genital herpes. Acyclovir is a synthetic nucleoside analogue that inhibits viral DNA polymerase, thereby preventing viral replication and reducing the severity and duration of outbreaks. Herperax Ointment is applied directly to the affected area, typically five times daily for 4 to 5 days, or as directed by a healthcare professional. It is most effective when initiated at the earliest signs of infection, such as tingling, redness, or itching. The ointment provides localized antiviral activity with minimal systemic absorption, reducing the risk of systemic side effects. Common adverse reactions may include mild irritation, burning, or itching at the application site. Herperax Ointment should not be used in patients with known hypersensitivity to acyclovir or any of its components. Caution is advised in patients with open wounds or severe skin conditions. This medication is intended for external use only and should be kept out of reach of children. Pregnant or breastfeeding women should consult a healthcare provider before use. Herperax Ointment offers an effective topical option for managing recurrent herpes simplex infections, promoting faster lesion healing and symptom relief.
