Important Safety Information

The following is the most important information that you should know about valacyclovir for the treatment of oral herpes.

Hims & Hers only offers access to valacyclovir as an Episodic Therapy for the treatment of recurrent oral herpes (cold sores) in adults. Recurrent oral herpes means that you have experienced an infection in the past (i.e., this is not the first time that you are experiencing a cold sore). If you have not been officially diagnosed with oral herpes by a healthcare provider in-person, you will be unable to receive valacyclovir through the Hims & Hers platform.

What is episodic therapy?

  • Episodic Therapy: This is when you take valacyclovir for an individual outbreak as it occurs. Episodic treatment must be initiated quickly to be effective. Ideally, you would start valacyclovir at the first sign of any prodromal symptoms (tingling, itching, pain, or burning) that precede some outbreaks or within 1 day of noticing an oral lesion. Research shows that this type of therapy can shorten the time to healing of the cold sore.

  • Valacyclovir does not cure oral herpes. There is no cure for oral herpes.

  • If you get cold sores, it is possible to spread herpes to others even when you don't have a cold sore that you can see.

    • People will often begin having symptoms 1-2 days before the actual cold sore shows up. This is called a prodrome. The symptoms of a prodrome often include pain, burning, itching, or tingling at the site where the cold sore will appear.

  • DO NOT have intimate or sexual contact with anyone when you have any symptoms that precede a visible infection (“prodrome”: burning, tingling, itching, or pain) or you have a visible cold sore, as you can transmit the herpes virus to them. During these times, it is suggested that you DO NOT:

    • Kiss anyone

    • Share utensils, glasses, towels, products that are applied to the lips (lip balm, lip gloss, lip stick, etc.)

    • Perform oral sex on anyone while you have symptoms of an oncoming infection or a visible herpes outbreak (cold sore) as you can transmit the virus to an uninfected partner’s genitals and give them genital herpes

Do not use valacyclovir for the treatment of oral herpes if you:

  • Have never had the diagnosis of oral herpes made by a healthcare provider in-person
