Among aciclovir-based products on the international market, Zovirax is one of the more broadly distributed brands, registered in 63 countries across the Americas, Europe, Asia, Africa, and Oceania. Its active ingredient, aciclovir, is classified as an antiviral for systemic use within the antiherpetic group, and it also appears in dermatological preparations. This page exists for the international reader trying to identify the brand abroad or place a locally prescribed product against a familiar name from home.
Zovirax is indicated for a range of viral infections caused by herpes-family viruses. The registered uses include herpes simplex infections such as cold sores and genital herpes, varicella-zoster infections such as chickenpox and shingles, herpetic keratitis affecting the eye, and prophylaxis against cytomegalovirus in certain patient populations. The structured indication section below this introduction reflects the uses formally registered in the markets where the brand circulates.
Because Zovirax is so widely distributed, travellers and expatriates often encounter the same medication in unfamiliar packaging — sometimes under the Zovirax name, sometimes as an aciclovir generic, and sometimes as another branded equivalent. Markets where the brand is registered include Brazil, Australia, Egypt, Canada, and the Czech Republic, but regulatory status, available formulations, and prescription pathways vary considerably between countries. A local pharmacist is well placed to confirm whether a given aciclovir-containing product on a foreign shelf is the appropriate substitute for what was prescribed at home.
Other medications in the antiherpetic and broader antiviral classes are also distributed globally under various molecules and brand names. Anyone taking Zovirax, considering it, or looking for a local equivalent while abroad should treat the choice as a clinical conversation with a healthcare provider rather than a self-directed swap at the counter.

Zovirax contains aciclovir, an antiviral classified within the antiherpetic group and used for systemic and dermatological viral infections. Aciclovir is one of the longest-established antiherpetic molecules in international use and circulates worldwide under several brand names as well as generics, particularly in markets where the original patent has long since expired.
Zovirax is registered in 63 countries spanning multiple regions, including Brazil, Australia, Canada, Egypt, China, Belgium, and Chile. The brand has a broad international footprint across the Americas, Europe, Asia, Africa, and Oceania. If your country is not represented in the list, a local pharmacist can usually confirm whether aciclovir is available locally under another brand name or as a generic.
Aciclovir is sold under numerous brand names worldwide and as a generic in most regulated markets, available in oral, topical, and injectable preparations depending on jurisdiction. Other molecules in the broader antiherpetic and antiviral classes also exist internationally, although they are not directly interchangeable without medical guidance. To identify a local aciclovir-containing product, search the active ingredient on Pill2Trip or ask a pharmacist.
In most countries Zovirax requires a prescription for its oral and injectable forms, while certain topical preparations may be available over the counter in some jurisdictions. Rules vary considerably between markets, and antiviral therapy is calibrated to the specific infection and the patient's circumstances. Travellers and expatriates should consult a healthcare provider or local pharmacist before starting, continuing, or substituting aciclovir abroad.
