Acyclovir is an antiviral medicine used for infections caused by certain herpes viruses. It can be ordered online, with current pricing shown during checkout and strength or form choices matched to the directions from your clinician. Oral tablets and topical acyclovir products are used differently, so the form, strength, and quantity should be checked before purchase.
Acyclovir is not an antibiotic and is not used for bacterial infections. It works against susceptible herpes-family viruses, including herpes simplex virus and varicella-zoster virus. Treatment timing, daily schedule, and duration depend on the condition being treated and the individual plan provided by a healthcare professional.
Acyclovir Price, Cost, and Form Selection
Acyclovir price depends on the form, strength, quantity, and package size shown during ordering. Tablet products are commonly compared by milligram strength and tablet count. Topical cream or ointment products are measured by concentration, tube size, and route of use rather than by tablet count.
When reviewing Acyclovir cost, compare the total amount of medicine in the package, not only the displayed dollar amount. Acyclovir 200 mg, Acyclovir 400 mg, and Acyclovir 800 mg tablets are different strengths. A larger count of lower-strength tablets is not automatically equal to a smaller count of higher-strength tablets because the schedule may differ.
| Ordering detail | What to check |
|---|---|
| Form | Confirm whether the medicine is an oral tablet or a topical acyclovir product. |
| Strength | Match the milligram strength or concentration to the clinician’s directions. |
| Quantity | Review tablet count, tube size, or total package contents. |
| Current price | Read the displayed amount together with strength, form, and quantity. |
| Use route | Do not substitute topical and oral forms for each other. |
People paying cash or comparing Acyclovir without insurance may focus on the cash price shown for the specific form. That comparison should still start with the correct active ingredient, strength, and route of use. Cash-pay ordering does not change the medical directions for how the medicine is taken or applied.
Quick tip: Compare the label attributes first, then compare totals across forms.
For broader antiviral browsing, the Antivirals category helps organize related medicines without treating them as automatic substitutes.
How to Order Acyclovir Online
Start with the form named in your treatment directions. Acyclovir tablets are swallowed, while acyclovir cream or ointment is applied to the skin. The two routes are not interchangeable at checkout because they may treat different situations and follow different instructions.
- Choose the oral or topical form that matches your directions.
- Check the strength, concentration, quantity, and package size.
- Enter patient and order information accurately during checkout.
- Keep clinician and treatment details available if clarification is needed.
Acyclovir US delivery from Canada may be part of the service context for some orders. Review the delivery address, package quantity, and storage instructions before completing payment. We may review order details when needed so the medicine, form, and quantity align with the information provided for the order.
The main ordering decision is precision. Acyclovir tablets, acyclovir cream, and acyclovir ointment may share the same active ingredient, but they do not replace one another in practical use. Choose the dose or strength shown during ordering only when it matches the written directions you were given.
Tablet Strengths, Cream, and Zovirax Generic Context
Generic Acyclovir contains the same active antiviral ingredient associated with Zovirax-branded acyclovir products. The brand relationship does not make every acyclovir form the same. Tablet strength, topical concentration, and package size still determine whether the item matches your treatment plan.
Acyclovir tablets are oral antiviral products. Common tablet strengths include 200 mg, 400 mg, and 800 mg, and those numbers refer to the amount of acyclovir in each tablet. They do not describe a complete course of therapy or prove how often the medicine should be taken.
- 200 mg tablets: Confirm the strength against your written directions.
- 400 mg tablets: Review the tablet count and daily schedule carefully.
- 800 mg tablets: Do not substitute based only on fewer tablets.
- Topical cream or ointment: Use only when a topical acyclovir product is intended.
Acyclovir dosage is individualized by condition, kidney function, age, immune status, and treatment goal. Do not change between 200 mg, 400 mg, and 800 mg tablets to simplify the schedule unless a clinician gives that instruction. If a brand name, generic name, concentration, or form appears in your directions, use those details to guide the order.
What Acyclovir Treats
Acyclovir is mainly used for viral infections caused by herpes simplex virus and varicella-zoster virus. Clinicians may use it for cold sores, genital herpes, shingles, or chickenpox, depending on the patient and the dosage form. It can reduce viral activity during treatment, but it does not cure herpes infections or remove the chance of future outbreaks.
Condition-focused navigation can help you understand nearby categories. Related areas include Cold Sores, Genital Herpes, Shingles, and Chickenpox. These condition pages help with browsing, but the medicine choice should still follow your clinician’s directions.
Timing can matter. Many antiviral treatment plans work best when started as directed soon after symptoms begin, while some plans are written for recurrent outbreaks or prevention in selected people. Follow the timing on your label or care plan rather than using symptoms alone to shorten, extend, or repeat treatment.
Acyclovir is not the same as amoxicillin. Amoxicillin is an antibiotic used for certain bacterial infections, while acyclovir is an antiviral used for susceptible herpes-family viruses. Acyclovir will not treat colds, flu, or bacterial infections.
How This Antiviral Works
Acyclovir is a nucleoside analogue antiviral. In plain terms, it interferes with viral DNA replication after activation inside infected cells. This helps slow the multiplication of susceptible herpes viruses during the treatment period.
The medicine’s activity depends on the virus type and the clinical situation. Herpes simplex virus types 1 and 2 and varicella-zoster virus are key targets described in drug references. A clinician may consider the infection site, symptom pattern, immune status, kidney function, and prior response when choosing a treatment plan.
Because acyclovir acts on viral replication, it is not a pain reliever, fever reducer, or skin protectant. Symptoms such as pain, burning, or rash may still need supportive care recommended by a healthcare professional. Seek guidance if symptoms worsen, spread near the eye, or do not follow the expected course.
Storage, Shipping, and Handling
Most oral acyclovir tablets are stored at room temperature, away from excess heat, moisture, and direct light. Keep tablets in the labeled container until use, and avoid bathroom storage because humidity can be high. Always follow the storage wording printed on the dispensed label.
- Tablets: Keep the container tightly closed and dry.
- Topical tubes: Close the cap firmly after each use.
- Travel: Keep the labeled container with the medicine.
- Home storage: Keep all medicines out of reach of children and pets.
Acyclovir is not typically handled like refrigerated injectable medicines, but the final label and pharmacy instructions still control storage. If a package arrives damaged, wet, or with unclear labeling, do not guess whether the contents are usable. Ask a pharmacist or clinician before taking or applying the medicine.
Available delivery choices are shown during checkout. Review the address, quantity, and handling needs before completing the order. Do not use prompt, express, cold-chain shipping wording as a substitute for reading the final storage instructions for the actual medicine received.
Side Effects, Warnings, and Monitoring
Common side effects can differ by form. Oral acyclovir may cause nausea, vomiting, diarrhea, headache, dizziness, or a general unwell feeling. Topical acyclovir may cause burning, stinging, dryness, itching, or irritation at the application site.
Serious side effects need prompt medical attention. Possible warning signs include swelling of the face or throat, trouble breathing, severe rash, reduced urination, unusual swelling, flank pain, confusion, hallucinations, tremors, or seizures. Kidney-related and nervous system effects are more concerning in older adults, dehydrated people, and people with kidney problems.
- Kidney history: Ask whether the strength or schedule needs adjustment.
- Hydration concerns: Discuss vomiting, diarrhea, or poor fluid intake.
- Immune concerns: Confirm the intended use and monitoring plan.
- Pregnancy or breastfeeding: Review benefits and risks with a clinician.
- Eye symptoms: Seek care for eye pain, vision changes, or lesions near the eye.
Why it matters: Kidney function affects how acyclovir is cleared from the body.
People using acyclovir for genital herpes should know that treatment does not eliminate transmission risk. Clinicians may recommend avoiding sexual contact during active sores or symptoms and using protective measures at other times. Those steps are part of the treatment plan and should not be replaced by ordering decisions.
Interactions and What to Avoid
Before taking acyclovir, share a complete medicine list with a healthcare professional. Some medicines can affect kidney function or change how acyclovir is cleared. Examples that may be relevant include probenecid, cimetidine, mycophenolate, certain antivirals, and other medicines that can stress the kidneys.
Alcohol is not usually the main interaction issue, but dehydration can make kidney safety more important. Vomiting, diarrhea, fever, poor fluid intake, or heavy sweating may increase concern. Ask what to do if you cannot drink fluids normally or cannot keep medicine down.
- Do not double doses: Follow the label or clinician instructions for missed doses.
- Avoid form switching: Tablets and topical products are not interchangeable.
- Do not share medicine: Another person may need different treatment.
- Report new symptoms: Confusion, severe rash, or reduced urination need attention.
Laboratory monitoring is not the same for every person. A clinician may consider kidney function, hydration status, immune status, age, and other medicines before or during treatment. The product order helps match form and strength, but it cannot determine an individual monitoring plan.
Related Antiviral Choices
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, safety considerations, and approved use context. A clinician should decide when another antiviral is appropriate.
Acyclovir is often discussed alongside valacyclovir and famciclovir, but those medicines are distinct products with different dosing patterns and clinical considerations. If your directions name acyclovir, choose acyclovir rather than switching based on condition alone. If another antiviral has been discussed, confirm the exact active ingredient and form before ordering.
Pet-related antiviral or anti-infective products should not be substituted for human treatment. If you are browsing animal medicines, use the separate Pet Medications category and follow a veterinarian’s instructions for animal care.
