Q: I know Valtrex is prescribed to treat genital herpes. If someone is exposed to a partner with herpes, will taking Valtrex right away destroy any of the virus that may have been acquired before it has a chance to take hold and become dormant? In other words, can Valtrex be used as sort of a "day after" medication?
A: We were intrigued by the idea that Valtrex might protect someone against genital herpes, so we asked the manufacturer, GlaxoSmithKline. GSK has never done a study to investigate this scenario. As a result, there aren't any clinical data to support the use of Valtrex as a "day after" medication or as a prophylactic drug in uninfected individuals whose sexual partners have genital herpes.
Q: My nails break, crack, split, peel and grow very slowly. They're not strong enough to open a soda can.
I take Synthroid for my thyroid, hydrochlorothiazide for blood pressure control, simvastatin for high cholesterol and Prevacid for heartburn. Could any of these affect my nails? Is there anything natural I could take or use? Nail hardeners seem to make the problem worse.
A: Many things may affect nail health. The proper balance of thyroid hormone has an impact. Cholesterol-lowering drugs like simvastatin (Zocor) have been linked to nail changes, and so has the acid-suppressing drug lansoprazole (Prevacid).
Avoid nail hardeners, since they may aggravate the situation. Some readers report that taking a dietary supplement called MSM (methylsulfonylmethane), commonly used for arthritis, may be helpful. Others tell us that moisturizing the nails with products such as Elon, Epilyt or almond oil helps.

Q: I've had an odd experience. I'm 66 and in good health, but my eyesight has deteriorated.
When I take Lunesta to go to sleep, the next day my eyesight is crystal-clear and needs no correction. Then, the following day if I don't take the sleeping pill, my eyes are so blurry and out of focus I have a hard time even with my glasses.
Has anyone else reported this?
A: We have searched the official label information and the medical literature and could find no reference to beneficial effects of Lunesta on vision. Have you considered the possibility that getting a good night's sleep makes the difference?
