Zovirax Tablets: Prices, Strengths, and Package Options in Canada

Zovirax is the established brand name for oral acyclovir tablets, an antiviral medicine used against herpes simplex and varicella-zoster virus infections. We carry Zovirax as oral tablets in three strengths, and the real decision for most customers is less about whether to choose Zovirax and more about which strength and pack size fit a specific course of treatment, an ongoing suppression plan, or another planned supply.

Below, we set out the strengths, pack sizes, and unit-value comparisons we currently offer, alongside the established medical background that explains why the strength and quantity you pick should follow the way acyclovir is actually used.

The Real Choices Behind Our Zovirax Prices

When you look at our Zovirax listing, three variables determine the price you see: strength, pack size, and the resulting price per tablet. We offer 200 mg, 400 mg, and 800 mg tablets, and each strength is sold in a different range of pack sizes rather than one fixed quantity. That structure exists because acyclovir is prescribed differently depending on the indication being treated, and a pack size that suits a short treatment course is not the same one that suits long-term suppressive use.

For tablets of the same strength, the pack size you choose is mainly a question of how much acyclovir you expect to need, how long you intend to keep a supply on hand, and how the resulting price per tablet compares across the available options.

How Do Our Zovirax Package Prices Compare Across Sizes?

Acyclovir tablets are priced per unit within each pack, and larger packs generally bring the price per tablet down, though the exact relationship depends on the specific pack size chosen. Rather than describing individual figures here, we've laid out the current pricing and unit value for our 400 mg Zovirax packs in the comparison below. This strength has six available package sizes, making it useful for comparing total price and unit value.

Use this comparison to weigh total price against price per tablet rather than choosing on total price alone. A smaller pack costs less upfront, while a larger pack usually delivers better unit value if you genuinely expect to use the full quantity before it expires or before your treatment plan changes. We'd rather you match the pack to a realistic plan for use than stretch a course longer than intended just because a bigger pack looked like the better deal.

Choosing the Right Zovirax Strength and Quantity

Acyclovir tablets are used at different strengths and frequencies depending on what is being treated, and our available pack sizes are built around that variation rather than a single one-size quantity.

• 200 mg tablets are commonly associated with treatment courses for recurrent genital herpes episodes, where dosing is typically spread across several doses a day for a short course.
• 400 mg tablets are frequently used for suppressive therapy taken on a regular ongoing schedule, as well as for treatment courses. We offer six package sizes at this strength.
• 800 mg tablets are typically used for higher-dose short courses, such as those used for shingles (herpes zoster) or chickenpox, where fewer, larger-dose tablets reduce the number of tablets needed per dose.

The table below summarizes the pack sizes we currently offer at each strength, so you can see at a glance which quantities are available before comparing prices.

A prescriber's instructions determine the strength, frequency, and duration that apply to a given case, and the pack size you order should be sized to that plan rather than to whichever quantity happens to carry the lowest unit price.

Zovirax as a Brand-Name Option Among Antiviral Tablets

Zovirax is the original brand-name formulation of acyclovir, and its tablets have a long track record as an oral antiviral for herpesvirus infections. Later oral antivirals include valacyclovir, a prodrug converted to acyclovir, and famciclovir, a prodrug converted to penciclovir. Both generally allow less frequent dosing than oral acyclovir.

We also carry Valtrex (valacyclovir) and Famvir (famciclovir) for customers whose prescriber has indicated a preference for a less frequent dosing schedule. Acyclovir tablets, including Zovirax, generally involve more doses per day than valacyclovir or famciclovir, but they remain a well-established option with decades of clinical use behind them, and some prescribers and patients simply continue with the regimen they know. The right choice among these tablets depends on the prescribed regimen rather than on brand alone, so we'd encourage matching your order to what's actually been prescribed.

What Zovirax Tablets Are Used For

Oral acyclovir is established for treating and, in some cases, suppressing infections caused by herpes simplex virus and varicella-zoster virus. In practical terms, that covers:

• Treatment of genital herpes outbreaks, both initial episodes and recurrences.
• Suppressive therapy to reduce the frequency of recurrent genital herpes episodes over an extended period.
• Treatment of herpes zoster (shingles) in adults.
• Treatment of varicella (chickenpox) in appropriate pediatric and adult cases, under a prescriber's specific dosing guidance.

Acyclovir does not cure herpesvirus infection or eliminate the virus from the body; it reduces viral replication during an active episode and can lower the frequency of recurrences when used for suppression, but the virus remains latent between episodes.

How Does Zovirax Work and How Should It Be Taken?

Acyclovir is a synthetic nucleoside analogue that resembles guanine, one of the building blocks of DNA. Once inside a cell infected with herpes simplex or varicella-zoster virus, a viral enzyme called thymidine kinase converts acyclovir into its active form, which then interferes with the viral DNA polymerase and halts new viral DNA synthesis. Because this activation step depends on a viral enzyme, acyclovir concentrates its effect in infected cells rather than acting broadly throughout the body.

Zovirax tablets can generally be taken with or without food, and treatment tends to work best when started as early as possible after symptoms begin, since acyclovir interrupts active viral replication rather than reversing tissue damage that has already occurred. Drinking adequate fluids while taking acyclovir, particularly at higher doses, supports normal kidney clearance of the medicine. Treatment courses for an active outbreak are typically measured in days, while suppressive regimens are taken continuously over a much longer period as directed by a prescriber.

Important Safety Information and Interactions

Common and Notable Effects

Acyclovir is generally well tolerated. The most frequently reported effects include nausea, headache, and diarrhea. Less commonly, acyclovir can affect kidney function, particularly at higher doses or in people with reduced kidney function, and can occasionally cause neurologic effects such as dizziness, confusion, or drowsiness, which can affect the ability to drive or operate machinery.

Who Should Take Extra Care

• People with a known hypersensitivity to acyclovir or valacyclovir should not take Zovirax.
• People with reduced kidney function may need dose adjustment and closer monitoring, since acyclovir is cleared primarily through the kidneys.
• Pregnant patients should use acyclovir only when a prescriber judges that the benefit justifies the potential risk, since acyclovir crosses the placenta.
• Breastfeeding patients should use acyclovir with caution, as it passes into breast milk, sometimes at levels higher than in maternal blood.
• Children under 2 years of age have not been fully studied for oral acyclovir safety and efficacy, so pediatric use depends on specific, weight-based prescriber guidance.

Acyclovir can interact with other medicines that affect kidney clearance, including probenecid, and with other nephrotoxic drugs. Sharing a full medication list with a prescriber or pharmacist before starting Zovirax helps identify any relevant interactions.

Storage

Store Zovirax tablets at 15°C to 25°C in a dry place, protected from light and moisture. Keep them in the original container and out of the reach of children, and do not use the tablets after the labelled expiry date.

What Do We Require to Order Zovirax in Canada?

Acyclovir oral tablets are classified as a prescription drug in Canada, meaning that Health Canada's regulatory framework treats this medicine as one that ordinarily requires a prescription to obtain. That classification describes the medicine's status in the Canadian market rather than our own checkout process.

On our side, we do not require you to submit a prescription document to place an order for Zovirax, so you can complete checkout without a prescription in hand. If you have questions about whether Zovirax is the right antiviral for your situation, our pharmacist is available to help, and we'd encourage anyone with an active or recurrent herpesvirus infection to discuss their diagnosis and dosing with a healthcare provider even when a prescription isn't required to order.

Ordering, Delivery, and Receiving Your Zovirax Order

We've been filling antiviral and other medicine orders since 2010, and our checkout is built around the same strengths and pack sizes described above, so the option you select is the one confirmed and shipped. Our support team is reachable 24/7 by email, online chat, or phone, and a pharmacist is available to answer questions about strength, dosing schedules, or interactions before you complete an order.

• Choose the strength and pack size that match your prescribed course or suppression plan.
• Confirm the selected option and quantity at checkout before payment.
• Contact our support team or pharmacist with any questions about dosing, storage, or interactions.
• Track your order through to delivery, with our team available if a delivery question comes up.

If your antiviral needs go beyond acyclovir, our AntiVirals catalogue also includes related oral options such as Valtrex and Famvir, in case a prescriber has indicated a different dosing schedule works better for your situation.

Bringing the Decision Together

Choosing among our Zovirax options comes down to matching the 200 mg, 400 mg, or 800 mg strength and the package quantity to the specific regimen directed by a prescriber. Depending on the indication and individual treatment plan, that may mean a short course for an active outbreak or a longer supply for suppression. Once that plan is clear, the package-value comparison above makes it straightforward to see which pack size gives the best price per tablet without overbuying beyond what a course or storage window calls for. From there, our checkout, support team, and delivery process are built to get the right strength and quantity to you with as little friction as the prescription status allows.
