Zavisol 5% Ointment – Acyclovir for Cold Sores and Herpes Simplex Overnight Treatment
Zavisol 5% Ointment contains Acyclovir 50mg/g in an ointment base, providing targeted antiviral therapy for herpes simplex labialis (cold sores), recurrent herpes simplex skin infections, and initial or recurrent herpes simplex lesions. The ointment's emollient, semi-occlusive base makes it especially well-suited for overnight use — it remains in prolonged contact with the lesion, maintaining a moist wound-healing environment that accelerates skin recovery and reduces crusting.
Unlike the cream formulation, the ointment provides greater occlusion, which may enhance acyclovir penetration into the affected dermal layers during rest periods. It is also beneficial for dry, crusted, or fissured lesions where added emolliency soothes the skin. Acyclovir selectively inhibits HSV DNA polymerase, arresting viral replication and limiting lesion extension. For best results, initiate therapy at the earliest prodromal symptoms.
Zavisol 5% Ointment is manufactured by Pharmasol. It is available from Derma.pk's Cream and Ointment collection and our Essential Health Products range. Prescription required — submit via email: sales@derma.pk or WhatsApp: +92-320-5999650.
