What is Zelitrex?
Zelitrex is an antiviral medicine used to treat infections with herpes viruses. This medicine works by stopping herpes viruses from reproducing and infecting more cells in the body. This relieves the symptoms associated with the infection. Zelitrex is a prescription-only medicine.
What is Zelitrex used for?
Zelitrex is used to treat and prevent (recurring) infections with herpes viruses. These include the viruses that cause:
- Cold sores (herpes simplex): a burning and/or tingling sensation on or around the lips that develops into painful, fluid-filled blisters with scabs.
- Genital herpes (herpes simplex): an STD that is likely to cause itching, pain, blisters with scabs on the genitals.
- Shingles (herpes zoster): pain and itching sensation, typically on one side of the body, followed by redness of the skin and blisters.
Zelitrex blocks the action of the herpes simplex and the herpes zoster virus and provides short-term relief from symptoms.
How to use Zelitrex
Zelitrex tablets should be swallowed whole with plenty of liquid. The tablets should be taken at the same time each day. They can be taken with or without food. It is important that you finish the entire course, even if you feel better. Typical courses range from one to ten days. Longer courses may be indicated for certain infections or to prevent re-infection.
