How Aciclovir Treats Cold Sores

Aciclovir is an antiviral medication that specifically targets the herpes simplex virus (HSV-1), the primary cause of cold sores in the UK [1]. Once absorbed, aciclovir converts into its active form within infected cells, where it inhibits viral DNA polymerase — the enzyme HSV-1 needs to replicate [1]. This mechanism stops the virus from multiplying, reducing both the severity and duration of outbreaks.

Clinical trials demonstrate that when aciclovir cream is applied at the first sign of tingling (the prodromal stage), it can reduce healing time by an average of 0.5 to 1 day compared to placebo [2]. Oral aciclovir tablets, typically prescribed at 200mg five times daily or 400mg three times daily, show even greater efficacy in moderate to severe outbreaks, particularly when treatment begins within 48 hours of symptom onset [2][3].

Aciclovir Cream vs Tablets: Which Form Is Right for You?

Aciclovir is available in two primary formulations in the UK: topical cream (5%) and oral tablets (200mg or 400mg). The cream works locally at the site of infection and is suitable for mild, infrequent cold sores that affect only the lip area. It requires no prescription when purchased as a pharmacy medicine, though our clinical team can advise on appropriate use during your consultation.

Oral aciclovir tablets are prescription-only and deliver systemic antiviral effects throughout your body [3]. UK prescribers typically recommend tablets for patients experiencing frequent recurrences (six or more episodes per year), severe outbreaks, or cold sores that spread beyond the lip margin. Tablets may also be prescribed as suppressive therapy, taken daily at lower doses to prevent future outbreaks in patients with recurrent HSV-1 infections [3].

Starting Aciclovir Treatment Early

The single most important factor in aciclovir efficacy is timing. Our pharmacists at Cured Pharmacy advise patients to begin treatment at the very first sign of tingling, itching, or redness — ideally before any visible blister forms. Studies confirm that early intervention significantly shortens outbreak duration and reduces the severity of symptoms [2]. Keeping aciclovir on hand before an outbreak occurs ensures you can start treatment immediately, maximising clinical benefit.

Who Can Use Aciclovir for Cold Sores?

Aciclovir is licensed in the UK for adults and children over 12 years of age when used as a cream, and for all ages when prescribed as tablets under medical supervision [1]. It is generally well-tolerated, with minimal systemic absorption from topical formulations. However, certain patient groups require careful assessment before treatment.

Pregnant and breastfeeding women should consult a UK prescriber before using aciclovir, though the medication is often considered safe when clinically necessary, as the benefits typically outweigh potential risks [3]. Patients with kidney impairment may require dose adjustments for oral aciclovir, as the drug is primarily eliminated through renal excretion. During your online consultation at Cured Pharmacy, our prescribers will review your full medical history, current medications, and any allergies to ensure aciclovir is appropriate and safe for you.

Contraindications and Cautions

Aciclovir should not be used if you have a known hypersensitivity to aciclovir, valaciclovir, or any excipients in the formulation. Patients taking other nephrotoxic medications or those with dehydration should inform their prescriber, as these factors may increase the risk of kidney-related side effects with oral aciclovir [3]. Our clinical team at Cured Pharmacy reviews these considerations during every consultation to ensure safe, individualised treatment.

How to Apply Aciclovir Cream Correctly

Proper application technique maximises aciclovir cream's effectiveness and minimises the risk of spreading infection. Wash your hands thoroughly before and after every application. Using a clean cotton bud or finger, apply a thin layer of cream to the affected area and approximately 1cm of surrounding skin, ensuring complete coverage of the cold sore [1].

Aciclovir cream should be applied five times daily (approximately every four hours, excluding overnight) for five days, or until the lesion has fully healed [1]. Avoid rubbing the cream in vigorously, as this can irritate already sensitive tissue. If you wear makeup, allow the cream to absorb for a few minutes before applying cosmetics. Never share your aciclovir cream with others, as this can transmit the herpes virus.

Common Side Effects and What to Expect

Aciclovir is generally well-tolerated, with most patients experiencing no side effects. Topical aciclovir cream may cause mild, transient stinging, burning, or dryness at the application site in approximately 1-2% of users [1]. These sensations typically resolve within minutes and do not require discontinuation.

Oral aciclovir tablets may occasionally cause headache, nausea, or gastrointestinal discomfort, particularly when taken on an empty stomach [3]. Taking tablets with food can reduce these effects. Serious side effects are rare but include allergic reactions (rash, swelling, difficulty breathing) and, very rarely, kidney problems in patients with pre-existing renal impairment or dehydration. If you experience any unusual or severe symptoms after starting aciclovir, contact your prescriber or pharmacist immediately. Our team at Cured Pharmacy is available on (+44) 116 4646009 for any treatment concerns.

Managing Minor Side Effects

If you experience mild stinging from aciclovir cream, applying a small amount of petroleum jelly around (not on) the treated area can help protect surrounding skin. For oral tablets, staying well-hydrated and taking doses with meals typically minimises gastrointestinal discomfort. Most side effects resolve within the first few days of treatment as your body adjusts to the medication.
