Short general description of Valtrex:

Valtrex (Valacyclovir hydrochloride) is an antiviral drug that is commonly prescribed to treat infections caused by herpes viruses, including genital herpes, cold sores, shingles, and chickenpox. It works by slowing the growth and spread of the virus in the body.

Valtrex is available in both brand-name and generic forms and is typically taken orally as a tablet. It is classified as a prodrug, which means that it is converted into acyclovir, the active form of the medication, in the body.

Valtrex is known for its effectiveness in reducing the severity and duration of herpes outbreaks, as well as its ability to prevent the transmission of the virus to others. It is commonly used for both acute treatment of outbreaks and long-term management of herpes infections.

Common side effects of Valtrex may include nausea, headache, and dizziness. It is important to follow the dosage instructions provided by your healthcare provider to ensure the medication is effective and safe.

  • Shingles: If you are dealing with shingles, the usual dose is 1000 mg (1 gram) three times a day for seven days.
