It is a prodrug of acyclovir. After you swallow a tablet, the body converts it to acyclovir, which blocks viral DNA replication. That action can shorten symptom duration and reduce viral shedding. Cold Sores, Genital Herpes, and Shingles are the main conditions treated. Valtrex® is the reference brand for this medicine.

Who It’s For

This treatment is used in adults for recurrent cold sores, first-episode and recurrent genital herpes, and shingles. It may be used in some children for cold sores or chickenpox when a clinician decides it is appropriate. People with frequent outbreaks may also use it for suppression to reduce recurrences.

Do not use it if you have had a severe allergic reaction to valacyclovir, acyclovir, or any tablet component. Tell your clinician if you have kidney problems, are on dialysis, or are immunocompromised. Dehydration can raise the chance of kidney side effects. Discuss pregnancy or breastfeeding with a healthcare professional before starting therapy. For symptom education, see Oral Herpes Symptoms and Genital Herpes Symptoms.

Dosage and Usage

Follow your prescriber’s instructions and the official label. Typical schedules depend on the condition and timing. For cold sores, many adults take a short one-day course started at the earliest tingling or burning. For recurrent genital herpes, short courses started at first signs may help. For first-episode genital herpes, a longer course is usually recommended. For shingles, treatment generally starts as soon as possible after the rash appears.

Tablets can be taken with or without food. Swallow with water and stay well hydrated. If you are using a suppression plan, try to take your dose at the same times each day. People with reduced kidney function often require adjusted dosing; your prescriber will determine that using lab results.

Strengths and Forms

Valacyclovir is supplied as oral tablets in 500 mg and 1 gram strengths. Availability can vary by manufacturer and country of origin.

Missed Dose and Timing

If you miss a dose, take it when you remember unless it is close to your next scheduled time. If it is almost time for the next dose, skip the missed dose and resume your regular schedule. Do not double up to make up for a missed dose. If you miss multiple doses or your symptoms change, contact your healthcare professional.

Storage and Travel Basics

Store tablets at room temperature in a dry place, away from moisture and direct light. Keep the bottle closed tightly and out of reach of children. Do not store in a bathroom or glovebox where heat and humidity vary. When traveling, bring your prescription label, enough tablets for your trip, and a small buffer in case of delays. Keep medicines in your carry-on to avoid exposure to extreme temperatures. Use a pill organizer only if you can keep original labels available for security and clinical verification.

Benefits

This antiviral can shorten the length and severity of outbreaks when started early. Suppressive plans may reduce how often outbreaks occur and can lower the risk of transmission when combined with safer practices. For shingles, starting therapy promptly can help with pain and rash resolution. Tablets offer convenient dosing without the need for injections. For cold sore education, see Herpes Symptoms.

Side Effects and Safety

• Headache
• Nausea or stomach pain
• Dizziness or fatigue
• Diarrhea
• Skin rash

Serious effects are uncommon but can include kidney problems, confusion, agitation, or hallucinations. Rare blood disorders like TTP/HUS have been reported, mainly in immunocompromised patients. Allergic reactions can occur and may involve hives, swelling, or trouble breathing. Stop the medicine and seek urgent care if you have serious symptoms. Drinking fluids and following your prescriber’s plan can help lower risk.

Drug Interactions and Cautions

Tell your clinician about all medicines and supplements you use. Probenecid and cimetidine can affect acyclovir levels. Using with other drugs that affect the kidneys, such as high-dose NSAIDs, some antivirals like tenofovir, or certain contrast agents, may increase side-effect risk. Alcohol does not directly interact, but dehydration can worsen tolerance. If you have kidney impairment or are elderly, you may be more sensitive to side effects.

What to Expect Over Time

With episodic use, many people notice outbreaks feel milder when started at the first sign. With suppression, recurrences may become less frequent over months of consistent use. Individual response varies. Keep communicating with your prescriber, and do not stop or change your plan without medical guidance. Adherence to timing, staying hydrated, and watching for triggers can support your results.

Compare With Alternatives

Several oral antivirals treat the same conditions. Famciclovir is another option with different dosing schedules that some patients prefer. Acyclovir is a long-standing alternative that may be suitable for certain patients. Your prescriber can help decide which option best fits your needs and health history. If you are researching telehealth and pharmacy routes, you may also find valtrex online information helpful for context.

Patient Suitability and Cost-Saving Tips

Most adults with herpes-family infections can discuss this treatment with a clinician. It may not be suitable if you have severe kidney disease or a known allergy to the drug class. Older adults and those using other medicines that affect kidney function need careful review. Use a single pharmacy when possible to help your care team check for interactions.

To stretch your budget, ask your prescriber if a multi-month fill makes sense. Setting refill reminders can help avoid last-minute local purchases. Some people prefer manufacturer-neutral options to reduce valacyclovir cost while maintaining the same active ingredient. Compare prices across available pack sizes and consider scheduling refills a little before you run out to prevent gaps in therapy.
