Please note: a valid prescription is required for all prescription medication.
Buy Acyclovir online with a valid prescription and compare current listed pricing, available presentations, and key safety basics before checkout. On this product page, you can review form and strength options such as tablets when listed, match the selection to your clinician’s directions, and see what may affect the Acyclovir price before ordering. If you are comparing US delivery from Canada, keep clinician contact and order details available if verification is needed.
Use the listing to confirm the selected product, quantity, and route of use before adding it to your cart. Oral tablets, topical cream or ointment products, and alternative antivirals are not interchangeable at checkout, even when they treat related viral infections.
Acyclovir Price and Available Options
Current listed pricing is the first item to compare, but the selected presentation matters just as much. A tablet listing may be priced by strength and quantity, while a topical product may be listed by tube size or concentration. The displayed amount should be read together with the product form, total count, and any pack details shown on the page.
When comparing Acyclovir cost, avoid assuming that two listings represent the same total treatment amount. A larger quantity of lower-strength tablets is not the same as a smaller quantity of higher-strength tablets, and topical products are measured differently from oral tablets. If a listing shows separate options, choose the exact form and strength written by the clinician.
| Ordering detail | What to compare |
|---|---|
| Current listed price | Check the displayed amount for the selected strength, form, and quantity. |
| Form | Confirm whether the product is oral, topical, or another presentation. |
| Strength | Match the mg strength or concentration to the prescribed directions. |
| Quantity | Review tablet count, tube size, or total package contents. |
| Access path | Keep payment and order details consistent with the selected prescription order. |
Customers comparing Acyclovir without insurance may look at cash-pay options when available. Cash-pay access does not change the need to select the correct presentation, and it does not replace the clinician’s instructions for how the medicine should be used.
Quick tip: Compare the product label details before comparing totals across different forms.

How to Buy Acyclovir Online
Start by selecting the presentation that matches the clinician’s directions. Check the strength, quantity, and product form before checkout, then provide the required order details. A valid prescription is required for this medicine, and the selected product should match the information provided by the prescriber.
- Choose the form shown on the prescription order, such as tablet or topical product.
- Check the listed strength, quantity, and package details.
- Provide requested patient and prescriber information during checkout.
- Keep supporting details available if the order must be checked.
Order details may be confirmed with the prescriber when needed. This helps ensure that the selected medicine, strength, and quantity align with the information supplied for the order.
The practical value of the page is comparison. You can review the currently listed option, decide whether the selected product matches the written directions, and understand important safety points before proceeding. There is no need to choose based on name alone, because form and strength can change the way a product is used.
Match the Form and Strength to Your Directions
Acyclovir tablets are oral antiviral products, and common prescription strengths include 200 mg, 400 mg, and 800 mg. Those numbers refer to the amount of active ingredient in each tablet, not to a complete treatment course. The prescribed dosage and number of daily doses are individual clinical instructions and should not be changed from the product page.
- 200 mg tablets: Confirm this strength if it appears on the written directions.
- 400 mg tablets: Check quantity carefully because daily schedules can differ.
- 800 mg tablets: Do not substitute based on tablet count alone.
- Topical products: Cream or ointment options are separate presentations.
Acyclovir cream or ointment products are applied to the skin, while tablets are swallowed. That difference affects package size, directions for use, and how the order should be matched to the prescriber’s instructions. A topical listing should not be treated as the same product as an oral listing.
Generic Acyclovir contains the active antiviral ingredient associated with Zovirax products, but the dosage form still matters. If the order specifies a brand, topical product, or exact strength, select the listing that matches those details rather than choosing only by active ingredient.
Uses and Product Fit
This antiviral is used for infections caused by certain herpes viruses, including herpes simplex virus and varicella-zoster virus. Clinicians may prescribe it for cold sores, genital herpes, shingles, or chickenpox, depending on the patient, diagnosis, and product form. It can help manage viral activity, but it does not cure herpes infections or remove the chance of recurrence.
People comparing condition-specific options can browse related product lists for Cold Sores, Genital Herpes, or Shingles. These pages can help with navigation, but the selected medicine should still match the clinician’s directions.
Timing can matter for antiviral treatment. Many instructions are written for starting as directed after symptoms begin or for ongoing management in certain patients. Follow the directions provided by the clinician rather than changing the schedule based on symptoms, package size, or a previous prescription.
Storage, Shipping, and Handling Basics
Most oral tablet products are stored at room temperature, away from excess heat, moisture, and direct light. Keep the medicine in its original container until use, and avoid storing tablets in a bathroom cabinet where humidity can be high. Always follow the storage details printed on the dispensed label.
- Tablets: Keep dry and tightly closed.
- Topical tubes: Close the cap firmly after each use.
- Travel: Keep the labeled container with the medicine.
- Children and pets: Store out of reach.
This product is not typically handled like refrigerated injectable medicines, but the final label and pharmacy instructions should guide storage. If a package arrives damaged, wet, or with unclear labeling, do not guess about whether the contents are usable; ask a pharmacist or clinician for direction.
Available shipping options are shown during checkout when the selected product and required order checks can proceed. Review the delivery address, product quantity, and storage needs before completing the order.
Safety Checks Before Checkout
Review key safety information before ordering. Oral treatment may cause nausea, diarrhea, vomiting, headache, or a general unwell feeling. Topical products may cause local burning, stinging, dryness, or irritation where applied. Side effects can vary by product form, health status, and other medicines being taken.
Serious reactions need prompt clinical attention. These can include signs of an allergic reaction such as swelling, trouble breathing, or severe rash. Kidney-related problems may appear as reduced urination, swelling, flank pain, or unusual tiredness. Nervous system effects such as confusion, hallucinations, tremors, or seizures have also been reported, especially in people with kidney problems or in older adults.
- Kidney disease: Ask whether the selected strength is appropriate.
- Dehydration risk: Discuss fluid guidance before treatment.
- Immune concerns: Confirm the intended use and monitoring plan.
- Pregnancy or breastfeeding: Review risks and benefits with a clinician.
- Severe rash: Seek urgent medical help.
Why it matters: Kidney function can affect how this medicine is cleared from the body.
People using treatment for genital herpes should also understand that antiviral therapy does not eliminate transmission risk. Clinicians may recommend avoiding sexual contact during active sores or symptoms and using protective measures at other times. Those instructions are part of the treatment plan, not a product-page decision.
Interactions and Health Details to Review
Before checkout, compare the current medicine list with the prescriber’s directions. Some medicines can affect kidney function or change how antivirals are cleared. Examples that may be clinically relevant include probenecid, cimetidine, mycophenolate, certain antivirals, and other drugs that can stress the kidneys.
Alcohol is not the main interaction concern, but dehydration, vomiting, diarrhea, or illness can make kidney-related safety more important. Ask a clinician what to do if fluid intake is limited or if symptoms make it difficult to take medicine as directed. Do not double up doses or change timing unless the clinician gives that instruction.
- Medicine list: Include prescriptions, supplements, and over-the-counter products.
- Kidney history: Share prior kidney disease or abnormal lab results.
- Older age: Ask whether monitoring is needed.
- Missed doses: Follow clinician or label instructions.
Laboratory monitoring is not the same for every patient. A clinician may consider kidney function, hydration status, immune status, or other health factors before or during treatment. The product page can help you select the right listing, but it cannot determine an individual monitoring plan.
Compare Related Antiviral Options
Several antiviral medicines are used for herpes-family viral infections, but they are not automatically interchangeable. Differences can include active ingredient, dosage form, dosing schedule, approved uses, and patient-specific safety factors. A prescriber should decide when a different antiviral is appropriate.
- Topical comparison: Zovirax Oint 5 may be reviewed when a topical acyclovir product is prescribed.
- Oral alternative: Famciclovir is a different antiviral option used for certain herpes-virus infections.
When comparing alternatives, focus on what the prescription order names first. Active ingredient, form, and strength are more important than choosing by condition alone. If a product seems similar but does not match the written directions, confirm the substitution with a clinician before ordering.

What is acyclovir mainly used for?
Acyclovir is mainly used for infections caused by herpes-family viruses. Clinicians may prescribe it for cold sores, genital herpes, shingles, or chickenpox, depending on the patient and the product form. Oral tablets and topical products are used differently, so the form listed on the prescription matters. It may reduce viral activity and help manage symptoms when used as directed, but it does not cure herpes infections or prevent all future outbreaks.
Can acyclovir be obtained over the counter?
Oral acyclovir generally requires a prescription in many locations. Some topical cold sore products sold without a prescription may contain different active ingredients, and they should not be treated as the same as prescription oral tablets. If symptoms are new, severe, recurrent, or involve the eyes, a clinician should assess the condition. The correct product depends on the diagnosis, location of symptoms, health history, and timing of treatment.
What is a serious side effect of acyclovir?
A serious side effect can involve the kidneys or nervous system. Warning signs may include reduced urination, swelling, flank pain, unusual tiredness, confusion, hallucinations, tremors, or seizures. Severe rash, facial swelling, or trouble breathing may suggest an allergic reaction and needs urgent care. Risk can be higher in people with kidney disease, dehydration, older age, or certain interacting medicines. A clinician can explain whether monitoring is needed.
What should I avoid while taking acyclovir?
Avoid changing the dose, stopping early, or doubling doses unless a clinician gives that instruction. People being treated for genital herpes should understand that acyclovir does not remove transmission risk; clinicians may advise avoiding sexual contact during active sores or symptoms. Avoid becoming dehydrated, especially if vomiting, diarrhea, fever, or poor fluid intake occurs. Also review other medicines with a clinician, particularly drugs that may affect kidney function.
What should I ask my clinician before starting acyclovir?
Ask which form and strength are intended, how long treatment should last, and what to do if a dose is missed. Mention kidney disease, pregnancy, breastfeeding, immune system problems, older age, and all current medicines or supplements. It is also helpful to ask which symptoms need urgent care, whether lab monitoring is needed, and how to reduce transmission risk if treatment is for a herpes infection.
