Acyclovir Cream
Acyclovir Cream
- In our pharmacy, you can buy acyclovir cream without a prescription, with delivery throughout Canada. Discreet and anonymous packaging is available.
- Acyclovir cream is used to treat herpes labialis (cold sores) and as a topical adjunct for genital herpes; it is a guanosine nucleoside analogue that is phosphorylated by viral thymidine kinase and inhibits viral DNA polymerase, blocking herpes simplex virus replication.
- The usual dose is to apply 5% cream to the affected area five times daily, starting at the first sign of symptoms; typical course is 4–5 days for cold sores and up to 5–10 days for genital lesions if needed.
- The form of administration is topical application as a 5% cream (usually supplied in 2 g–10 g tubes).
- Onset time: symptom relief or reduced lesion progression is generally seen within 24–48 hours when treatment is started early (prodromal stage gives best results).
- Duration of action: the treatment course typically lasts 4–5 days for cold sores (extendable to 10 days if healing is incomplete); individual applications require repeated dosing and do not provide prolonged single-dose protection.
- Alcohol warning: there is no specific interaction between alcohol and topical acyclovir, so alcohol consumption does not alter its effect; avoid using alcohol-containing skin products on the treated area.
- Most common side effec: local burning or stinging at the application site (may also cause mild dryness, redness or itching).

Approved Uses (Health Canada DIN Context)
When is topical acyclovir indicated in practice?
| Indication | Product Label Text |
|---|---|
| Herpes Labialis (Cold Sores) | Topical acyclovir 5% cream is indicated for treatment of herpes labialis. |
| Localized Herpes Simplex Lesions | Adjunct topical therapy for limited localized lesions. |
Off-Label Patterns In Canadian Healthcare
Can topical acyclovir be used outside approved indications?
- Occasional adjunctive topical use for small genital lesions under clinician guidance.
- Clinicians usually prefer oral antivirals such as valacyclovir or famciclovir for systemic control or frequent recurrences.
- Immunocompromised patients generally require systemic therapy rather than topical monotherapy.
Layman’s Explanation
How does acyclovir cream stop a cold sore?
Acyclovir cream enters infected skin cells and stops the virus copying its DNA, which slows lesion growth and shortens the episode when applied early at the prodrome stage.
Topical application keeps the effect local with very little systemic absorption when used as directed.
Clinical Detail From Health Canada Resources
What is the pharmacology behind the local effect?
- Prodrome
- Early tingling or burning that signals an impending cold sore.
- Thymidine Kinase
- Viral enzyme that phosphorylates aciclovir to its active form inside infected cells.
- DNA Polymerase
- Enzyme inhibited by the phosphorylated aciclovir, preventing viral replication.
Standard Regimens Per Canadian Guidelines
What is the usual dosing schedule for cold sores?
- Start at the first sign of a cold sore (tingling or prodrome).
- Apply acyclovir 5% cream to the affected area five times daily.
- Continue for 4–5 days, extending to 10 days if healing is incomplete.
- Avoid mucous membranes and eyes; use on intact skin around the lesion only.
- If a dose is missed, apply as soon as remembered and continue with the regular schedule.
Adjustments By Patient Type (With Canadian Clinical Notes)
Do children or elderly need different dosing?
| Patient Group | Adjustment/Counsel |
|---|---|
| Children | Topical dosing typically for those aged 12 years and older; younger children need prescriber advice. |
| Elderly | No routine dose change; monitor for increased skin sensitivity. |
| Immunocompromised | Topical monotherapy may be insufficient; systemic antiviral therapy is commonly used. |
| Renal/Liver Impairment | Topical use generally unchanged, but caution with prolonged or large-area application. |
Common Contraindications (Health Canada-Approved List)
Who should not use acyclovir cream?
- Patients with known hypersensitivity to aciclovir, penciclovir, or any cream excipients.
- Avoid use on open wounds, mucous membranes, or in the eyes.
Rare But Serious Events (Canadian Pharmacovigilance Data)
What rare reactions should you watch for?
Severe local allergic reactions such as contact dermatitis have been reported rarely with topical use.
Secondary bacterial infection can occur if lesions break down or are picked at, requiring medical review.
Report serious adverse events through Canada Vigilance to ensure national pharmacovigilance records are up to date.

Topical acyclovir cream 5% is an established option for herpes labialis when applied at prodrome and is supplied in 2g–10g tubes by well-known brands such as Zovirax and multiple generics.
Check the tube for a DIN to confirm Health Canada registration and ask a pharmacist about minor-ailment options in your province if you cannot access a GP quickly.
