Valcyte (Valganciclovir HCl) 8 U( O B1 e2 i2 R& Z7 ^( g2 g% t9 B, b( G
Valcyte (valganciclovir HCl) is an antiviral medicine that can treat the CMV (cytomegalovirus) infections of the eye. The CMV can be transmitted to a baby before even being born. The infection is usually harmless and rarely causes any diseases. For most healthy individuals that get this virus on birth, there are a few symptoms and no long term medical consequences. Once in the organism, the virus remains active, but generally latent throughout the patient’s life. There are two different forms of infection – primary and recurrent. The primary infection can cause more problems in pregnancy than the recurrent one. Anyway, if the immune system is weakened, the virus can easily turn active and cause various complications. Most infected adults and children don’t present any symptoms. Those who do, might present fever, gland inflammations, tiredness and fatigue. These symptoms usually show up 1 to 3 months after the infection is encountered.$ J& J. } H. e5 T/ D2 @# f
: i( y* B$ p7 d9 B4 G Valcyte (valganciclovir HCl) initially hit the market in 2001. It was immediately accepted by the FDA. The latest concentration formula is up since 2009 though. Although the CMV infection is not quite harmful, this medicine requires a medical prescription. As some of the CMV symptoms can easily be taken for a cold or a flu, the specialist doctor must first identify the exact cause of your condition. This medicine is only prescribed in the AIDS patients, with a low immune system. It might be too powerful for other people. 9 n: N: e: f* G% p+ ] ! t4 d" u" @4 m; [4 ~ Administration # ^' ~* n5 o!

Valcyte (valganciclovir HCl) is available in two forms – tablets and oral suspension. The tablets are prescribed both for adults and children. They need to be swallowed whole, without being crushed or chewed. You can take them with a glass of water. Take both the tablets and the oral suspension with food. The food will help your organism assimilate the drug faster. The children who encounter problems while trying to swallow the tablets whole may get the oral suspension form of this medicine. The oral suspension is not quite advised in adults, since the dosage will be different at higher doses. 3 b, U/ U! n/ E ' @6 m3 Y& r5 a$ ]6 q: s The oral suspension form of Valcyte (valganciclovir HCl) comes with a special device used to measure the dose. Although it might look like a spoon, don’t use other similar tools, but only this medical recipient.- ~. a) h) H, ]0 n
