Valtrex® Tablets for Herpes Infections

Valtrex is an antiviral tablet used to treat herpes infections. It helps shorten outbreaks and supports suppression plans when prescribed. This page explains how the medicine works, who it’s for, and how to use it safely.

What Valtrex Is and How It Works

This antiviral is used for cold sores, genital herpes, and shingles. It’s available with US delivery from Canada, and many patients ask about paying without insurance. Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.

The active ingredient is valacyclovir. In the body, it converts to acyclovir. It then blocks viral DNA polymerase, slowing replication of HSV-1, HSV-2, and VZV. Starting treatment early in an outbreak may help reduce lesion duration and pain. For suppression, daily dosing can lower the frequency of recurrences when advised by your clinician.

Who It’s For

This treatment is indicated for adults with shingles and for adults with initial or recurrent genital herpes. It is also used for cold sores in adults and adolescents when prescribed. Suppressive therapy may be appropriate for adults with frequent genital herpes outbreaks or for risk reduction in certain partnerships, as directed by a healthcare professional. Learn more about conditions it treats in our resources on Cold Sores and Genital Herpes, and see care strategies in Genital Herpes Treatment.

People with known hypersensitivity to valacyclovir or acyclovir should avoid it. Dose adjustments are usually required for reduced kidney function. Older adults and those who are dehydrated have higher risk for side effects. Discuss pregnancy or breastfeeding plans with your prescriber before starting this therapy.

Dosage and Usage

Follow the exact directions on the prescription label. Typical adult schedules include: shingles treated for seven days; initial genital herpes treated for ten days; episodic genital herpes treated for a few days; cold sores treated over a single day with high-dose, split administration. Some adults may use daily suppression for genital herpes to reduce recurrences and transmission risk when advised.

Take tablets with or without food and drink water regularly. Swallow whole. Start episodic therapy at the first sign of tingling, itching, or pain. For prescriber-directed courses, Valtrex® 1 g dosing is common for shingles and some regimens. Always defer to the official label and your clinician’s guidance for your condition.

Strengths and Forms

Tablets are the standard form. Common strengths include 500 mg and 1 g. Availability may vary by pharmacy and manufacturer.

• valacyclovir hcl 500 mg tablets are commonly used for episodic therapy and suppression.
• 1 g tablets are used for shingles and other labeled schedules.

Some patients may receive blister packs while others receive bottles. Your pharmacist will dispense the appropriate product based on your prescription.

Missed Dose and Timing

If you miss a dose for a multi-day regimen, take it when remembered unless it’s close to the next dose. Skip the missed one if timing is tight. Do not double up. For cold sores, the single-day, split-dose schedule should be followed as directed; if you miss the second dose, contact your prescriber for advice. Try to begin episodic therapy at the very first prodrome sign for the best effect.

Storage and Travel Basics

Store tablets at room temperature in a dry place away from excessive heat and light. Keep the bottle tightly closed and out of reach of children and pets. When traveling, carry the original labeled container and a copy of your prescription. Airport screening systems do not harm the medicine. Keep a small supply in your carry-on in case checked bags are delayed. If ordering for a trip, note that our partners use temperature-controlled handling when required.

Keep the valacyclovir 1 g tablet in its original container until use. Do not store in bathrooms where moisture is high. Ask your pharmacist about local take-back programs for expired or unused tablets.

Benefits

This therapy can lessen the duration and severity of outbreaks when started early. For suppression, once-daily plans can reduce recurrence frequency and help lower transmission risk when combined with safer sex practices and condom use. Tablets are convenient for at-home use and can be taken with or without meals. Many patients appreciate simple dosing and the ability to start episodic therapy at the first sign of symptoms.

Side Effects and Safety

• Headache
• Nausea or stomach pain
• Dizziness or tiredness
• Diarrhea

Serious effects are uncommon but can include kidney problems, confusion, agitation, hallucinations, or decreased urination, especially in older adults or those with kidney impairment. Rare blood disorders like TTP/HUS have been reported in immunocompromised patients. Seek urgent care for signs of allergic reaction such as hives, swelling, or trouble breathing. Stay hydrated during therapy to lower the risk of kidney-related side effects.

Drug Interactions and Cautions

Tell your prescriber about all medicines and supplements you use. Medicines that affect kidney function may increase the risk for side effects with this treatment. Probenecid and cimetidine can raise blood levels of the antiviral. Use caution with other nephrotoxic agents or certain antivirals. Dose adjustments are often required in renal impairment. If you are pregnant, planning pregnancy, or breastfeeding, review risks and benefits with your clinician. Alcohol does not directly interact but can worsen dehydration; use moderation.

What to Expect Over Time

When taken at the first sign of an outbreak, episodic therapy may help shorten healing time and reduce pain. For suppression, it can take steady daily use to see fewer recurrences. Some people may still experience breakthrough episodes. Keep a small supply on hand for episodic starts if prescribed. Track triggers, such as illness, sun exposure, or stress. For a refresher on symptoms, see Herpes Symptoms. Consistent use as directed and follow-up with your healthcare professional support the best outcomes.

Compare With Alternatives

Other approved antivirals for herpes include acyclovir and famciclovir. These medicines differ in dosing frequency, pill burden, and cost considerations. Some people prefer fewer daily doses, while others prioritize specific schedules recommended by their prescriber. You can review alternatives like Acyclovir and Famciclovir to discuss with your clinician.

Availability and Substitutions

Product availability can vary. If a strength or brand is temporarily unavailable, your prescriber may recommend a therapeutically equivalent alternative. Pharmacists may dispense an authorized generic when appropriate and allowed by your prescription. To compare generics, see Valacyclovir 500mg and review dosing differences with your clinician before switching.

Patient Suitability and Cost-Saving Tips

This medicine may suit adults with episodic outbreaks who can start treatment quickly at symptom onset. Daily suppression may be considered for those with frequent recurrences. It may be less suitable for people with severe renal impairment unless dosing is adjusted by a prescriber, or for those with prior allergy to acyclovir-class antivirals.

Budget planning tips include comparing brand and generics, setting up 60- or 90-day supplies when appropriate, and scheduling follow-ups to refine your plan. Searching for generic valacyclovir cost can help you discuss options with your clinician. Use refill reminders in your account to prevent gaps. For travel, keep doses in your carry-on and store them properly at your destination.
