Uses of Valtrex

Valtrex is also known by the generic name Valacyclovir

USES:
Valacyclovir is used in children to treat cold sores (herpes labialis) and chickenpox (varicella zoster). It is used in adults to treat cold sores and shingles (herpes zoster). Valacyclovir does not cure these diseases, but it may decrease pain and help sores heal faster. Valacyclovir belongs to a class of medications known as antivirals.

Valacyclovir is also used to treat people with genital herpes who are currently having an outbreak. It can also be used to prevent an outbreak (suppressive therapy). This medication helps control symptoms, but does not cure the disease or prevent infection of sexual partners.

If you are taking valacyclovir for treatment of genital herpes, it is important to follow safe sex practices to lower the chance of giving herpes to your partner, even if there are no symptoms present. Always use a condom made of latex or polyurethane. When you have symptoms or are experiencing an outbreak, do not have sexual contact with your partner.

Uses of Coumadin

Coumadin is also known by the generic name Warfarin

USES:
This medication is used to treat blood clots (such as in deep vein thrombosis-DVT or pulmonary embolus-PE) and/or to prevent new clots from forming in your body. Preventing harmful blood clots helps to reduce the risk of a stroke or heart attack. Conditions that increase your risk of developing blood clots include a certain type of irregular heart rhythm (atrial fibrillation), heart valve replacement, recent heart attack, and certain surgeries (such as hip/knee replacement).

Warfarin is commonly called a "blood thinner," but the more correct term is "anticoagulant." It helps to keep blood flowing smoothly in your body by decreasing the amount of certain substances (clotting proteins) in your blood.
