Zovirax (aciclovir) is licensed for herpes simplex, herpes zoster and neonatal HSV, and buyers can specify the originator brand or a licensed generic aciclovir tablet or IV vial against the same tender line.
Zovirax, the originator brand for aciclovir, is an oral and intravenous antiviral that hospital pharmacies rely on for herpes simplex, herpes zoster and, in its IV form, neonatal herpes and HSV encephalitis, where dosing is weight-based rather than a flat adult dose. M Care Exports is a merchant exporter: we source Zovirax and licensed generic aciclovir tablets, oral suspension and IV infusion vials through Indian distribution and manufacturing channels and dispatch on quote, not from our own manufacturing.
Aciclovir exporter and bulk supplier from India.
For hospital, wholesaler and tender-desk orders, M Care quotes aciclovir against buyer specification: brand (Zovirax) or generic, dosage form (200 mg, 400 mg or 800 mg tablets, oral suspension, or 250 mg powder for solution for infusion) and destination-market regulatory documentation, drawn from licensed WHO-GMP manufacturer lines on the M Care roster. Because the IV vial's supply can tighten intermittently, tied to thin manufacturer numbers for an older, low-margin injectable, we confirm current lot availability and lead time before quoting rather than assuming standing stock, then align CTD/eCTD or country-specific dossier paperwork to the destination regulator's requirements.

Synthetic guanosine analogue antiviral; viral DNA polymerase inhibitor, sourced and documented for export.
Aciclovir is a synthetic guanosine analogue: once phosphorylated inside a herpesvirus-infected cell, it inhibits viral DNA polymerase and halts replication, with far less effect on uninfected cells because activation depends on a viral thymidine kinase. Its flagship licensed uses are herpes simplex (skin, mucous membrane and genital), herpes zoster (shingles), and, for the IV form specifically, neonatal herpes simplex virus infection and herpes simplex encephalitis, plus prophylaxis in immunocompromised patients. It is supplied both as an oral solid, needing no reconstitution, and as an IV powder for solution for infusion that a pharmacist reconstitutes and dilutes before a slow infusion; destination-country labelling should be checked for the exact licensed indications and paediatric dosing before a quote is finalised.
Active ingredient

Forms and strengths
200 mg tablet; 400 mg tablet; 800 mg tablet; 200 mg/5mL oral suspension; 250 mg powder for solution for infusion, per vial.
Indications
Aciclovir, a guanosine-analogue antiviral originally marketed as Zovirax, is licensed for herpes simplex, herpes zoster and, in its IV form, neonatal herpes simplex virus infection and herpes simplex encephalitis. Supplied from Indian WHO-GMP facilities as brand or licensed generic to regulated and semi-regulated markets outside India.
Administration
Oral, Intravenous. Tablet, oral suspension, and powder for solution for infusion.
Documentation
Batch-specific CoA, CoPP, manufacturing-site WHO-GMP certificate and stability data compiled per consignment, in the format the destination regulator expects.
Hospital pharmacies, licensed importers and tender desks across our export markets.
India is our origin. We do not sell into the Indian market.
Buyers for aciclovir are hospital pharmacists running neonatal and immunocompromised-patient protocols where the IV form is the only option, dermatology and genitourinary medicine outpatient pharmacies dispensing oral tablets for genital herpes and zoster, MoH tender desks holding aciclovir as a standing antiviral formulary line, licensed importers and wholesalers, and NGO or humanitarian procurement programmes supplying aciclovir sodium vials for outbreak and refugee-setting care.
GCC registration routes
Supply against MoH registration held by your local licensed importer, or via the GCC central registration pathway.
UK unlicensed routes
Where no UK licence exists, the MHRA Specials and named-patient import routes cover clinically justified demand.

What the dispensing pharmacist checks on aciclovir.
Aciclovir's IV label carries two labelled warnings: renal failure, sometimes fatal, from crystal precipitation in renal tubules if the drug's aqueous solubility limit is exceeded or it is given by bolus, and thrombotic thrombocytopenic purpura/haemolytic uraemic syndrome in immunocompromised patients, also sometimes fatal. That is why IV aciclovir must run as a slow infusion over a minimum of one hour, never a push, with the patient adequately hydrated throughout. Reconstituted IV solution has a pH of approximately 11 and must never be given orally or intramuscularly; the diluted solution should be used promptly, within the in-use period stated on the label, and should not be refrigerated. Dosing is weight-based for neonatal HSV and encephalitis rather than a flat adult dose, and both oral and IV doses step down for renal impairment by extending the dosing interval. Oral tablets need no reconstitution and are stored below 25 degrees Celsius with a 36-month shelf life; IV vials are also stored at 20-25 degrees Celsius unopened, so neither form needs validated cold-chain handling, but IV lot availability should be confirmed given the thin pool of manufacturers still producing this older injectable.
The documentation pack a regulator actually asks for.
Both the oral tablet and the IV powder for solution for infusion travel on standard ambient, temperature-controlled logistics rather than the validated cold-chain lanes M Care runs for biologics; storage for each is below or at 20-25 degrees Celsius, not refrigerated. Aciclovir sits on the WHO Model List of Essential Medicines in three formulations: IV powder and solution, oral liquid, and oral tablet, for herpes simplex, zoster, varicella and viral CNS infections, plus a topical 3% ophthalmic ointment for herpes simplex keratitis, so most MoH tender desks in Africa and the GCC carry it as a standing antiviral line. On the brand-versus-generic question, Zovirax remains the originator product, and licensed generic aciclovir tablets, oral suspension and IV vials from multiple manufacturers are separately registered and marketed in the US, UK and EU, so buyers genuinely have a brand-or-generic choice; the emc lists UK-authorised generic tablets from manufacturers including Wockhardt UK alongside Zovirax. The IV form specifically has seen periods of tight supply in recent years, consistent with being an older, low-margin injectable with few manufacturers still investing in production, so M Care confirms current lot availability with the sourcing partner before quoting rather than assuming standing stock. Aciclovir is not a controlled substance in any of M Care's served markets, so import documentation follows standard prescription-only-medicine requirements.

Aciclovir supply, the specific questions.
Does a generic version of Zovirax exist?
Yes. Licensed generic aciclovir tablets, oral suspension and IV infusion vials from multiple manufacturers are registered and marketed in the US, UK and EU alongside the originator brand Zovirax. Registration status for generic aciclovir varies by destination country, so M Care checks local approval before quoting brand or generic against a specific tender.
Can M Care supply Zovirax to our market?
Yes, on an import basis. We source Zovirax and licensed generic aciclovir through Indian pharmaceutical distribution channels and dispatch against your import authorisation and any local registration your pharmacy, hospital or wholesaler holds.
Why does the IV vial need more careful lead-time planning than the tablets?
Parenteral aciclovir is an older, low-margin injectable with few manufacturers still producing it, so supply can tighten intermittently, unlike the tablet forms which see broader generic competition. M Care confirms current lot availability and lead time with the sourcing partner before quoting a tender that specifies the IV form.
What are the key safety warnings for IV aciclovir?
IV aciclovir's label carries two warnings: renal failure, in some cases fatal, from crystal precipitation in the renal tubules if the drug is given too fast or without adequate hydration, and thrombotic thrombocytopenic purpura or haemolytic uraemic syndrome in immunocompromised patients, also sometimes fatal. This is why the label requires a slow infusion over at least one hour, never a bolus, with the patient kept well hydrated.
Does aciclovir need cold-chain shipping?
No. Both the oral tablets and the IV powder for solution for infusion are stored at standard controlled room temperature, below or at 20 to 25 degrees Celsius, and shipped on ambient logistics, not the validated cold-chain lanes M Care runs for biologics. The reconstituted or diluted IV solution should also never be refrigerated once prepared, only used promptly.
What dosage forms and strengths can M Care supply?
Oral tablets in 200 mg, 400 mg and 800 mg strengths, an oral suspension for patients who cannot swallow tablets, and 250 mg powder for solution for infusion for hospital IV use, matching the WHO Essential Medicines List formulations and the Zovirax range. Tell us your indication mix, herpes simplex, zoster, or neonatal and immunocompromised IV protocols, and we quote the dosage-form and strength split accordingly.
