Valtrex dosage
The recommended dosage of Valtrex varies based on the type of HSV that’s being treated, as well your age. Generally, the most common dosages are as follows:
- For adults with cold sores, a dose of 2,000 mg of Valtrex typically used, with a secondary dose of 2,000 mg within 12 hours.
- For adults treating a first outbreak of genital herpes, 1,000 mg of valacyclovir two times daily for a total of 10 days. It’s recommended to begin treatment within 48 hours of the herpes symptoms becoming noticeable.
- For adults with recurring genital herpes, 500 mg of valacyclovir two times daily for a total of three days. It’s recommended to begin valacyclovir treatment as soon as a recurrent herpes symptom becomes visible.
It’s important to note that these are typical dosages and may not be appropriate for you based on your symptoms, age, body weight and general health. The best approach for treating any virus, including HSV, is talk to your doctor and follow their treatment advice.
It’s especially important to talk to your doctor if you have a weakened immune system or kidney disease, as these health conditions can affect the safety of valacyclovir treatment. Breastfeeding or pregnant women should also discuss the risks of valacyclovir treatment with their doctor.
Valacyclovir is known to potentially interact with other antiviral and immunosuppressant drugs, particularly those used in HIV/AIDS management. Medications that can potentially interact with valacyclovir include foscarnet, tenofovir, mycophenolate, zidovudine and the varicella virus and zoster virus vaccines.
If you use any of these medications, you should discuss potential interactions with your doctor before considering valacyclovir or any other herpes treatment.
