Acyclovir Cream 5% – What You Need to Know

If you’ve ever gotten a cold sore, you know how annoying it can be. Acyclovir cream 5% is a common over‑the‑counter option that can speed up healing and keep the virus from spreading. It’s a thin, white lotion that you rub onto the sore a few times a day. The active ingredient, acyclovir, works by stopping the herpes virus from multiplying, which means the sore gets smaller faster.

How to Apply Acyclovir Cream Correctly

First, wash your hands and the affected area with mild soap. Pat dry – you want the skin dry so the cream can stick. Squeeze a pea‑sized amount of cream onto your fingertip, then gently spread it over the entire sore and a millimeter around the edge. Do this five times a day, ideally every 3‑4 hours, for at least 4‑5 days. Even if the sore looks better after a couple of days, keep using the cream for the full course to avoid a rebound.

If you’re treating multiple sores, repeat the steps on each one. Remember not to share the cream or your towel with anyone else – the virus can spread through direct contact with the medication.

When to See a Doctor

Most people see improvement within 48‑72 hours, but if the sore doesn’t shrink after a week, or if you develop fever, swollen lymph nodes, or intense pain, it’s time to call a doctor. Same goes for people with weak immune systems, pregnant women, or anyone who gets cold sores very often. A professional might prescribe a stronger dose or an oral antiviral instead of the cream.

Side effects are usually mild. Some users notice itching, mild burning, or a dry feeling where the cream was applied. If you see a rash, swelling, or trouble breathing, stop using it right away and seek medical help.

Buying acyclovir cream 5% is easy. Most pharmacies keep it on the shelf, but you can also order it from reputable online pharmacies that require a prescription for higher‑strength versions. Check the packaging for an expiration date and make sure the label lists “acyclovir 5%” clearly – counterfeit products often have misspelled names or different concentrations.

Store the tube in a cool, dry place away from direct sunlight. If the cream thickens or changes color, discard it. Keeping it at room temperature helps retain its potency.

To avoid future outbreaks, combine the cream with good skin care: use sunscreen on your lips, avoid sharing utensils or lip balms, and manage stress – all of which can trigger the virus.

In short, acyclovir cream 5% is a straightforward, affordable way to tackle cold sores faster. Follow the application schedule, watch for side effects, and don’t hesitate to see a doctor if things don’t improve. With the right routine, you’ll notice fewer days of pain and a lower chance of spreading the virus to friends or family.
