Valtrex

valaciclovir

Valtrex is used for treating Herpes virus infections like genital herpes, cold sores, shingles, chicken pox, etc. The antiviral drug slows down the growth and spread of herpes virus so that the body can defend against the antigen self. Valtrex helps in lessening the symptoms of the disease but does not completely cure the ailment.

Valtrex inhibits the multiplication of the viral DNA thus inhibiting the multiplication of the virus. Valtrex is also referred to as pro drug, where the drug does not actively participate in the eradication of the disease; else, it indirectly slows down the multiplication cycle of the virus, by forming acyclovir that aids the body to fight against the infection. Valtrex has long half life than acyclovir; hence it is advisable to consume the drug few times in a day.

The treatment should be started immediately on or before the onset of symptoms like tingling, burning sensation, blisters, etc. The medicine is not effective once you take it after the symptoms have prolonged for 1 or 2 days.

Valtrex also does not prevent the spread of genital herpes, and hence the infection is contagious and can spread easily even if you are taking the medication. It is better to avoid sex in adults if you are infected by the virus. It is better to avoid the infected areas from contacting the healthy persons. It is wise to avoid touching the infected parts of your body before touching eyes, and other sensitive areas. The hands should be washed with soap if you touch the infected parts.

Valtrex should be used exactly as informed by your physician. Each dose should be taken along with one full glass of water. Valtrex also can be taken with or without food. Valtrex helps in minimizing the virulence of the symptoms but does not treat viral infection like cold, flu, etc.

The standard dosage recommended for shingles is 1gm to 3 gm daily for one week consecutively. The standard dosage for genital herpes is 1gm twice a day for 10 days, followed by 500mg twice daily for 3 days. 1 mg of Valtrex should be taken once day regularly if you are prone to more than 10 infections per year. However, Valtrex should not be used continuously for more than 1 year. 2mg of the drug is taken twice daily for 1 day about 12 hours apart for treating cold sores. Person suffering from kidney problems have to use the drug in low doses.

In case if you happen to miss a dose, do not have both the doses together. If the dosage clashes, it is better to avoid the previous dose and continue with the current dose. It is also better to consult your physician in case of any doubts regarding the dosage amount.

The side effects of Valtrex are similar to that of acyclovir. Some of the common side effects include,

• Headache
• Nausea
• Vomiting

Less common side effects like,

• Diarrhea
• Abdominal pain
• Dizziness is also common.

Herpes virus can pass from infected mother to child during the child birth. When you are pregnant, take care not to develop herpes lesions as it is very contagious for the baby. If you get lesions, take care to keep the lesions dry and wear loose clothing to prevent irritation.

Valtrex can be stored at room temperature away from direct light and moisture. Expired medicines should be disposed and should not be used.
