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 Benadryl

Benadryl is also known by the generic name Diphenhydramine Hcl

USES:
Diphenhydramine is an antihistamine used to relieve symptoms of allergy, hay fever and the common cold. These symptoms include rash, itching, watery eyes, itchy eyes/nose/throat, cough, runny nose and sneezing. It is also used to prevent and treat nausea, vomiting and dizziness caused by motion sickness. Diphenhydramine can also be used to help you relax and fall asleep.

This medication works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction. Its drying effects on such symptoms as watery eyes and runny nose are caused by blocking another natural substance made by your body (acetylcholine).

Cough-and-cold products have not been shown to be safe or effective in children younger than 6 years. Therefore, do not use this product to treat cold symptoms in children younger than 6 years unless specifically directed by the doctor. Some products (such as long-acting tablets/capsules) are not recommended for use in children younger than 12 years. Ask your doctor or pharmacist for more details about using your product safely.

These products do not cure or shorten the length of the common cold and may cause serious side effects. To decrease the risk for serious side effects, carefully follow all dosage directions. Do not use this product to make a child sleepy. Do not give other cough-and-cold medication that might contain the same or similar ingredients (see also Drug Interactions section). Ask the doctor or pharmacist about other ways to relieve cough and cold symptoms (such as drinking enough fluids, using a humidifier or saline nose drops/spray).
