At our pharmacy, you can purchase Valtrex without a prescription, with delivery throughout the USA within 5-14 days. Discreet and anonymous packaging.
Valtrex is used for the treatment of herpes simplex virus (HSV) infections, including cold sores (herpes labialis), genital herpes, and for the treatment of shingles (herpes zoster). The medication is a prodrug of acyclovir, which after oral administration is rapidly converted to acyclovir, a nucleoside analogue that inhibits viral DNA synthesis by interfering with viral DNA polymerase, stopping viral replication and reducing the severity and duration of outbreaks.
The usual dosage of Valtrex varies by condition: for cold sores, 2 grams twice daily for 1 day; for initial genital herpes, 1 gram twice daily for 10 days; for recurrent genital herpes, 500 mg twice daily for 3 days or 1 gram once daily for 5 days; for suppressive therapy of genital herpes, 500 mg or 1 gram once daily; for shingles, 1 gram 3 times daily for 7 days.
The administration form is tablets (500 mg, 1000 mg).
The effect of the medication begins within 1‑2 days of starting treatment, with symptom relief typically within 3‑5 days.
The duration of action is typically 1‑10 days for acute outbreaks, or long‑term for suppressive therapy.
Alcohol consumption is not recommended during treatment, as it may worsen side effects and reduce immune function.
The most common side effects are headache, nausea, abdominal pain, and dizziness.

Mechanism and Pharmacology

Valtrex contains valacyclovir, the L‑valyl ester prodrug of acyclovir. After oral administration, valacyclovir is rapidly converted to acyclovir by first‑pass intestinal and hepatic metabolism. Acyclovir is a nucleoside analogue that is selectively phosphorylated to acyclovir monophosphate by viral thymidine kinase in herpes simplex virus (HSV)‑infected cells and varicella‑zoster virus (VZV)‑infected cells. Further phosphorylation by cellular kinases yields acyclovir triphosphate, which inhibits viral DNA polymerase and incorporates into viral DNA, causing chain termination. Valacyclovir has significantly higher oral bioavailability (about 55%) compared to acyclovir (10‑20%), allowing for less frequent dosing.

Indications and Usage

Valtrex is indicated for:
- Treatment of herpes zoster (shingles) in immunocompetent adults.
- Treatment of initial and recurrent episodes of genital herpes in adults.
- Suppression of recurrent genital herpes in immunocompetent and HIV‑infected adults.
- Treatment of herpes simplex labialis (cold sores) in adults and children (≥12 years).
- Reduction of transmission of genital herpes to susceptible partners (in combination with safer sex practices).
- Treatment of chickenpox (varicella) in immunocompetent children (≥2 years).

Critical Warnings and Limitations

High‑Risk Groups
Elderly: Dose adjustment is required in elderly patients with reduced renal function; start with lower doses and monitor for neurotoxicity (confusion, agitation).
Pregnancy: Valacyclovir is classified as FDA Pregnancy Category B. Studies have not shown an increased risk of birth defects. Use during pregnancy only if clearly needed. The Acyclovir Pregnancy Registry has not identified an increased risk of major malformations.
Breastfeeding: Valacyclovir is converted to acyclovir, which is excreted in human milk in low concentrations; caution is advised, but it is generally considered compatible with breastfeeding.

Activity Interactions
Driving: May cause dizziness or drowsiness – exercise caution when operating vehicles or machinery.
Alcohol: Avoid alcohol consumption as it may worsen side effects and impair immune response.

Dosage Guide

Standard Regimens
Cold sores (herpes labialis): 2 grams twice daily for 1 day (taken 12 hours apart).
Initial genital herpes: 1 gram twice daily for 10 days.
Recurrent genital herpes: 500 mg twice daily for 3 days, or 1 gram once daily for 5 days.
Suppressive therapy for genital herpes (immunocompetent): 500 mg or 1 gram once daily. For patients with 9 or fewer recurrences per year, 500 mg once daily; for 10 or more recurrences, 1 gram once daily.
Suppressive therapy for genital herpes (HIV‑infected): 500 mg twice daily.
Herpes zoster (shingles): 1 gram 3 times daily for 7 days.
Chickenpox (varicella, children ≥2 years): 20 mg/kg (maximum 1 gram) 3 times daily for 5 days.
Renal impairment: Dose adjustment based on creatinine clearance (CrCl):
- CrCl 30‑49 mL/min: reduce dose to 500 mg twice daily (for genital herpes) or 1 gram once daily (for shingles).
- CrCl 10‑29 mL/min: reduce dose to 500 mg once daily (for genital herpes) or 1 gram every 24 hours (for shingles).
- CrCl

Special Populations
Pediatric: Dosing based on body weight and age; refer to prescribing information.
Geriatric: Monitor renal function and adjust dose accordingly.

Side Effects and Contraindications

Common side effects:
- Headache
- Nausea
- Abdominal pain
- Dizziness
- Fatigue
- Diarrhea

Serious side effects requiring medical attention:
- Severe allergic reactions (rash, hives, swelling of the face/lips/tongue, anaphylaxis)
- Neurotoxicity (confusion, hallucinations, agitation, seizures) – more common in elderly or renally impaired patients
- Acute kidney injury (especially in patients with pre‑existing renal disease or dehydration)
- Thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS) – rare, mainly in immunocompromised patients
- Severe skin reactions (Stevens‑Johnson syndrome, toxic epidermal necrolysis)

Absolute contraindications:
- Hypersensitivity to valacyclovir, acyclovir, or any excipient in the formulation.

Drug Interactions

Significant interactions include:
- Probenecid: Increases acyclovir levels (since valacyclovir is converted to acyclovir) by inhibiting renal tubular secretion; dose reduction may be needed.
- Cimetidine: May increase acyclovir plasma levels by reducing renal clearance; no dose adjustment typically required.
- Nephrotoxic drugs (e.g., NSAIDs, aminoglycosides, cyclosporine, tacrolimus): Increased risk of acute kidney injury; monitor renal function.
- Mycophenolate mofetil: May increase acyclovir levels; monitor for toxicity.
- Live vaccines (varicella, zoster): Avoid concurrent use; valacyclovir may reduce immune response to live vaccines.

Practical Guidelines

Administration
Take Valtrex with a full glass of water. Drink plenty of fluids to maintain hydration and prevent kidney damage. Swallow tablets whole; do not crush or chew. May be taken with or without food (food does not affect absorption). For cold sores, start treatment at the first sign of symptoms (tingling, itching). For suppressive therapy, take exactly as prescribed, even between outbreaks. If a dose is missed, take it as soon as remembered unless it is near the next dose; do not double dose.

Monitoring
Regular monitoring required for long‑term suppressive therapy or in patients with renal impairment:
- Renal function (serum creatinine, BUN) at baseline and periodically
- Neurological status (especially in elderly or renally impaired patients)
- Complete blood count (rarely needed)

Storage
Store at room temperature (20‑25°C / 68‑77°F), away from moisture and heat. Keep tablets in original container, tightly closed. Do not store in the bathroom.

Alternative Medications

• Acyclovir (Zovirax): The parent drug, less bioavailable, requires more frequent dosing (5 times daily).
• Famciclovir (Famvir): Prodrug of penciclovir, also effective against HSV and VZV, with convenient dosing.
• Penciclovir (Denavir) cream: Topical treatment for cold sores.
• Docosanol (Abreva) cream: Over‑the‑counter topical agent for cold sores.
• Lysine supplements: Limited evidence for prevention of herpes recurrences.

Clinical Effectiveness

Valacyclovir has superior oral bioavailability compared to acyclovir, allowing for twice‑daily or once‑daily dosing. In clinical trials, for cold sores, a 1‑day regimen of 2 grams twice daily reduced healing time by 1‑2 days. For initial genital herpes, 1 gram twice daily for 10 days was as effective as acyclovir. For recurrent genital herpes, short‑course (3 days) of 500 mg twice daily reduced lesion duration. Suppressive therapy with 500 mg once daily reduced recurrence rates by 75‑80%. For shingles, 1 gram 3 times daily for 7 days reduced the duration of postherpetic neuralgia. Valacyclovir is also effective in reducing transmission of genital herpes to susceptible partners (by about 50%).

Important: Valtrex requires medical supervision and should only be used under prescription. Do not stop treatment early, as this may allow the infection to recur or worsen. Complete the full course as prescribed, especially for initial episodes. For suppressive therapy, regular follow‑up is recommended to re‑evaluate the need for continued treatment. If you experience confusion, hallucinations, or signs of kidney problems (decreased urine output, swelling), seek immediate medical attention. Always inform your doctor about all medications and any history of kidney disease before starting treatment.
