Brand vs. Generic – The major branded products are Zovirax (Pfizer) and Acyclovir (GSK). Generic versions are produced by a wide range of companies (Sandoz, Teva, Sun Pharma, etc.) under the same name “acyclovir” and generally cost less.
Dosage & Concentration – The most common injectable form is 5 mg/mL. Vials are typically 10 mL (5 mg/mL × 10 mL = 50 mg) or 20 mL (100 mg). Some manufacturers offer 10 mg/mL vials for higher‑dose regimens.
Regulatory Status –
- US FDA – Products listed above have either an FDA‑approved brand name or have received a generic approval (ANDA).
- EMA (Europe) – GSK and Pfizer products are authorized for use in the EU; generics must meet EU GMP and have a CE mark.
- Indian GMP – All manufacturers listed for India have GMP certification and are registered with the Drugs Controller General of India (DCGI).
Supply Chain – Manufacturers often supply both hospitals and pharmacies. For large‑scale procurement (e.g., in national health programmes), the product is typically supplied as pre‑filled syringes or 10 mL vials in a 100 mg or 250 mg dose pack.
Prescription & Usage – Acyclovir injection is indicated for acute HSV, VZV, and CMV infections. It is prescription‑only. In most countries, pharmacists will verify the prescription before dispensing.

Step	What to Do
1	Identify the region where you need the drug.
