Tamiflu is taken for treatment or prevention of influenza infection. For treatment, Tamiflu is taken twice daily, but for prevention it is taken once daily.

How often and how long you take Tamiflu can be different depending on what you are taking it for, so make sure you take it as instructed. It is important to finish this medication, even if symptoms disappear. Tamiflu can be taken with or without food, but if stomach upset occurs, take it with food. Tamiflu works best if you take it on schedule. Tamiflu cannot be used to treat a cold, and be aware that you can still spread the flu while taking Tamiflu.

The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
