Drug treatment varies depending on whether you have recurring disease or whether you are trying to prevent it. When treating oral herpes early, oral medications can relieve pain and shorten healing time.

To treat recurrent herpes, the following medications reduce the severity and duration of outbreaks:

  • Ointments or creams help reduce pain and itching and speed up healing time.
  • Oral antiviral medications, available by prescription only, can be used at the first signs such as heat and itching. This medicine has very little effect when the acne is already swollen.
  • Medicines can be taken daily to prevent pain, especially in people who often suffer from pain.
  • If your immune system is naturally weak and you get sick, you will need to take high doses to control your symptoms and take daily doses of medication to keep the illness from coming back.
  • Although rare, children and adults with weakened immune systems may also need antibiotics during severe herpes episodes to treat bacterial superinfections.
