Valtrex tablets are an antiviral drug which make use of an active ingredient known as valaciclovir. Your body breaks this ingredient down into acyclovir which can be used to treat viral infections such as herpes. This also includes cold sores and genital herpes. Aciclovir stops these viruses from spreading and infecting other cells throughout your body.

Aciclovir activates once it gets inside the infected cells, blocking an enzyme in the virus called DNA polymerase. This enzyme is what allows the virus to multiply and spread to other cells within the body. Because aciclovir blocks this enzyme, the virus cannot multiply, allowing your natural immune system to control the infection.

Valaciclovir is an oral treatment for herpes simplex and other viral infections, including genital herpes. Valaciclovir is an effective treatment for preventing the recurrence of viral flare-ups and is most effective if used as soon as symptoms begin to appear.

If you suffer from flare-ups regularly that you might need to take Valtrex regularly in order to suppress the viral infection. When taken regularly valaciclovir can also reduce the chance of passing your infection to other people sexually. It is also recommended to wear condoms and practice safe sex. When the sores are visible and present it is recommended to avoid sex altogether.

It should be known that Valtrex does not eliminate the risk of passing on the virus sexually and should not be relied upon for safe sex practices. Always practice safe sex, even when using Valtrex.

You should try to avoid dehydration while using Valtrex so plenty of water should be consumed; this is even more important if you are over 65 years old or have had problems with your kidneys in the past.

You can take Valtrex tablets with or without food. The exact dose will depend on a number of factors including your condition and the length of treatment required. Always follow your doctor's instruction. The instructions will be printed on the medication's accompanying label.

Always complete the full course of medication as prescribed by your doctor, even if you believe that your infection may have subsided. If you miss a dose take it as soon as you remember unless it is almost time for your next dose. If this is the case it is okay to skip a dose - never take a double dose in order to make up for a missed one.

  • Headache
  • Feeling sick
  • Dizziness

  • Skin reaction after exposure to sunlight (photosensitivity).

Frequently Asked Questions

  • Should I avoid anything while using Valtrex?

    Sex should be avoided while using any medication for herpes as there is a chance you may pass the virus on to other people. Herpes is very contagious and you can infect others even while using Valtrex. If you do have sex, make sure to use a condom that provides protection against STIs in order to prevent the spread of the virus. Do not let infected areas come into contact with other people, and avoid touching your eyes after touching the infection. Wash your hands as regularly as possible. This medication should not be shared with others, even if they are suffering from the same condition.

  • Will any other drugs affect Valtrex?

    In rare cases Valtrex can harm your kidneys. The chance of this happening increases if you are using other medications, including:

    • Antivirals
    • Chemotherapy
    • Injected antibiotics 
    • Bowel disorder medication
    • Transplant rejection medication
    • Injected osteoporosis medication
    • Some pain medication such as aspirin, Tylenol, and Advil

    Some other drugs may also interfere with Valtrex, including herbal remedies and vitamin supplements. Always inform your healthcare professional as to anything you are taking before beginning a course of new medication.
