For most adults, the typical Valtrex dosage for cold sores is 1 gram twice daily for one day, then 500mg twice daily for four days. This means you’ll take two 500mg tablets in the morning and two more in the evening, for a total of six doses.
Children require different dosages, always determined by their weight and doctor’s instructions. Never administer adult dosages to children. A doctor will calculate the appropriate amount based on the child’s specific needs. This careful adjustment ensures the medication’s effectiveness and minimizes potential side effects.
Early treatment is key. Starting Valtrex at the first sign of a cold sore – tingling, itching, or redness – can significantly shorten the duration and severity of the outbreak. Remember, this information is for guidance only; always consult your physician or pharmacist for personalized advice and to discuss any potential drug interactions or pre-existing health conditions.

Valtrex Dosage for Cold Sores: A Practical Guide
For initial outbreaks, adults typically take 1 gram of Valtrex (valacyclovir) twice daily for one day, or 500 mg twice daily for one to ten days. Children’s dosage depends on their weight and age; consult your doctor for precise instructions.
Managing Recurrent Cold Sores
To manage recurrent outbreaks, a lower dosage is often prescribed. This might involve 500 mg once daily or 500 mg twice daily, depending on your medical history and the frequency of your cold sores. Your doctor will tailor the dosage to your specific needs. Always follow their instructions meticulously.
Important Considerations
Remember to inform your doctor about any other medications you’re taking, as interactions are possible. Also, report any unusual side effects immediately. While generally well-tolerated, Valtrex can cause mild side effects like headache or nausea. Proper hydration can help minimize potential side effects. Accurate diagnosis is key; ensure your cold sores are properly identified by a healthcare professional before starting treatment.
Understanding Valtrex Prescription and Dosage for Cold Sores
Your doctor will determine the appropriate Valtrex dosage based on your individual needs and medical history. Typical prescriptions for cold sores involve taking Valtrex tablets twice daily.
For initial outbreaks: A common prescription is 2 grams, taken once, followed by 1 gram twice daily for a total of five days. This helps reduce the severity and duration of symptoms.
For recurrent outbreaks: To prevent future occurrences, your doctor might prescribe a lower daily dose, like 500 mg once or twice daily, taken for a specific period. The duration of treatment varies based on individual response and the frequency of outbreaks.
Always follow your doctor’s instructions precisely. Adjusting the dosage or duration without consulting your physician could reduce the drug’s efficacy or lead to unwanted side effects.
Important Note: Valtrex is an antiviral medication; it doesn’t cure cold sores, but it can significantly shorten their lifespan and reduce their severity. Taking the medication at the first sign of a cold sore is crucial for optimal results. Contact your doctor immediately if you experience any side effects.

When to See a Doctor and Potential Side Effects of Valtrex
Contact your doctor immediately if you experience severe allergic reactions, such as difficulty breathing, swelling of your face, lips, or tongue, or hives. These are serious and require immediate medical attention.
Also, seek medical advice if your cold sores don’t improve after a week of taking Valtrex, or if they worsen. This could indicate an underlying issue requiring different treatment.
While Valtrex is generally well-tolerated, some people experience mild side effects. These can include nausea, headache, and diarrhea. These side effects are usually temporary and resolve without intervention. However, persistent or bothersome side effects warrant a call to your doctor.
Less Common Side Effects
Less frequent, but still possible side effects include dizziness, fatigue, and abdominal pain. Inform your doctor about any side effects, regardless of severity, to ensure your safety and receive appropriate guidance.
When to Adjust Dosage
Never adjust your Valtrex dosage without consulting your doctor. They can assess your condition and determine the best course of action if needed.
