Tips for Taking Valtrex
For the treatment of recurring outbreaks, the recommended dose is Valtrex 500 mg, taken twice a day for three days.
Genital Herpes Suppression
For preventing future outbreaks of genital herpes, the recommended dose is Valtrex 1000 mg (1 gram), taken once a day, every day. For people who have had fewer than ten outbreaks of genital herpes in one year, the Valtrex dosage may be decreased to 500 mg a day, every day.
For people with HIV and genital herpes who have a CD4 cell count equal to or greater than 100 cells/mm3, the dose of Valtrex to prevent future outbreaks is 500 mg, taken twice a day, every day. Valtrex has not been studied in people with HIV who have a CD4 cell count less than 100 cells/mm3.
Preventing the Spread of Genital Herpes
To decrease the chances of spreading genital herpes to sexual partners, people who have had fewer than ten outbreaks per year can take Valtrex 500 mg once a day. The medication has not been studied for this use in people who have ten or more outbreaks per year. Safer sexual practices should still be used. Condoms should always be used, and sexual contact should be avoided during an outbreak.
Your child's healthcare provider will calculate the recommended Valtrex dose for chickenpox based on your child's weight. In general, the recommended dose for children age 2 to 18 years old is 20 mg per kg (about 9 mg per pound) three times a day for five days. The dose should not exceed 1000 mg three times daily, although this only becomes important for larger children.
Some considerations for people taking Valtrex include the following:
- Valtrex should be taken at the first sign of an outbreak. It works best if taken as early as possible. In fact, the medication may not work if taken too late.
- Your Valtrex dose(s) should be taken at the same time each day.
- If you do not take the medication as scheduled, take your next dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take a double dose.
- Your Valtrex dosage can be taken with or without food. If the medication bothers your stomach, try taking it with food.
- For the drug to work properly, you have to take it as prescribed. Valtrex will not work if you take it differently than how your healthcare provider recommends.
- If you are unsure about anything related to Valtrex or your Valtrex dosage, talk to your doctor, nurse, or pharmacist. Do not stop taking the medicine without discussing it first with your healthcare provider.
- The dose of Valtrex is decreased for people who have poor kidney function. If you have kidney problems, ask your healthcare provider about which dose you should be taking.
