Description Active Ingredients: Aciclovir 5% Dosage: At first sign of tingle or blister apply a small amount to the affected area 5 times daily for 4 days. The earlier you treat a cold sore, the better. The best time to start treatment is when that tingling sensation first happens, before any visible sign of a cold sore appears. If you miss it, don’t worry, it’s not too late to treat. Always read the label. Use only as directed. If symptoms persist see your healthcare professional.
