 [ Symptoms ] what to do with 19 year old that just wants to have babies  she is 19 and has 5 babies her mother wants to get her tubes tied the doctor said yes and is now saying no she just had premie baby boys about a month aga and is already having sex again should we seek the advice of another doctor all her babies are under the age of 4 [ Disease ] well let is establish a few medical facts before we delve into the issue of whether or not valacyclovir caused the symptoms you described first of all the flu  or influenza   can only be caused by coming in contact with the influenza virus thus taking valacylovir and going for a run cannot cause you to get the flu second nausea is not a symptom of influenza the flu is a respiratory virus it affects your nasal passages and lungs it is true if you swallow a lot of post nasal drip caused by the influenza virus you might get nauseated but generally speaking the flu is a respiratory virus it is true that nausea and headache are potential side effects of valacyclovir however i am not aware of fever and chills being known side effects of this drug to be fair the most common side effects of all medications are nausea and diarrhea so i tend to consider those as expected side effects if your flu like symptoms persist you definitely should return to your healthcare provider for further evaluation enlarged lymph nodes should not be taken lightly if your fever exceeds 101 3f seek emergency medical attention meanwhile drink a lot of fluids it is entirely possible you coincidentally picked up a virus just as you began your course of valacyclovir the onset of your symptoms may have nothing to do with the medication but the symptoms are worthy of being evaluated further if they do not go away within a couple of days wishing you well in response to the answer above i never said the valacyclovir caused the flu the specific term i used was brought on also a common symptom of the flue as i found online is vomiting so unless people vomit without feeling nauseous i dont see how nausea isnt a symptom of the flu thanks for your response though
