Overview

Lovir 400mg Tablet is a prescription-only medicine (POM) presented as a tablet, with Aciclovir 400mg as its active ingredient content.

This page is limited to product, safety and handling information, in line with Malaysian rules on prescription medicine information for the public. Your prescriber or pharmacist is the right source for anything beyond that, together with the leaflet inside the pack.

Through DoctorOnCall, this product is supplied after an online consultation with a licensed doctor and a valid prescription, and it is checked by a registered pharmacist before dispensing. Take it exactly as prescribed, and speak to your doctor before stopping, changing the dose, or starting any other medicine alongside it.

Directions for Use

Take Lovir 400mg Tablet with a full glass of water, with or without food, and try to start treatment as soon as possible after symptoms begin, such as tingling or the first sign of a blister, for the best effect. Complete the full course as prescribed, even if your symptoms improve before it is finished.

Dosage

The usual dose of Lovir 400mg Tablet depends on the condition being treated – for example, genital herpes or shingles typically require multiple daily doses for 5-10 days, while long-term suppressive therapy may use a lower, ongoing dose. Your doctor will determine the specific dose, frequency, and duration appropriate for your infection.
