Paroxetine (e.g., HCl) + Dipyridamole Sertraline + Prednisolone BACKGROUND OF THE INVENTION 0002 The invention relates to treating viral infections 0005. In another aspect, the invention features a method Such as influenza. Diseases caused by viruses are major health for treating or preventing a viral infection in a patient. The problems worldwide, and include many potentially fatal or method includes administering to the Subject an amount of an disabilitating illnesses. Influenza virus, for example, affects SSRI sufficient to treat or prevent the viral infection in the 5-15% of the population during epidemics and causes upper patient. In certain embodiments, the patient has not been respiratory tract infections. Hospitalization and deaths can diagnosed with or does not suffer from depression, major occur, especially in high-risk groups (elderly, chronically ill depressive disorder, obsessive-compulsive disorder, panic and immuno-compromised). Between three and five million disorder, posttraumatic stress disorder, social anxiety disor cases of severe influenza and between 250,000 and 500,000 der, generalized anxiety disorder, or premenstrual dysphoric deaths are recorded every year around the world. Accord disorder. The SSRI may be selected from the group consisting ingly, there exists a need for reducing influenza and other viral of cericlamine, citalopram, clovoxamine, cyanodothiepin, infections. dapoxetine, escitalopram, femoxetine, fluoxetine, fluvoxam ine, ifoxetine, indalpine, indeloxazine, litoxetine, milnacip SUMMARY OF THE INVENTION ran, paroxetine, Sertraline, tametraline, Viqualine, and Zimel dine; or analog thereof. 0003) We have identified agents and combinations of 0006. In another aspect, the invention features a method agents which reduce inflammatory response in cells infected for treating or preventing a viral infection in a patient.
