Tamiflu (oseltamivir) for Influenza "I came down with the flu while traveling for work, and a local clinic wrote me a prescription. The Dr told me it wouldn't make me feel better but rather shorten the duration. I figured might as well try it. I've stopped after 3 doses - awful diarrhea and nausea. I'd rather let nature take its course than go through what I have for the last 10 hours."

Tamiflu (oseltamivir) for Influenza "After taking the second dose of Tamiflu I began to throw up unconditionally. I could eat or drink anything for over a day. I only took 3 doses. Not worth it at all! Just makes you very sick. Now it's been 4 days since I took my last dose of 3 pills, and I can still hardly stomach food & my stool is pale."

Tamiflu (oseltamivir) for Influenza "Be aware of the side effects before taking this medication. The doctor said I had the flu and prescribed me tamiflu. 75mg every 12 hours. I started having headaches and shortly after that I started vomiting severely with intense abdominal pain. I had to rush to the hospital because the stomach pain was unbearable. When I got to the hospital the doctor told me to stop taking tamiflu. I’m still feeling the abdominal pain but not as bad and still can’t eat anything. Never again will I be taking this medication!!"

Tamiflu (oseltamivir) for Influenza "This is the worst "medicine" I have ever taken... I went to urgent care and it was prescribed to me, the next morning I took one pill and within 30 minutes I started vomiting. I vomited 4 times within 1 hour and then was dry heaving. Then I did a little bit of research on the drug and some of these reviews are scary! Hallucinations? Really?! its not worth it, don't waste your money and time. I would rather suffer through the flu than EVER take another one of those pills again. I learned my lesson, always do some research before taking a new medication. My doctor didn't mention any side effects to me, nor did the packaging mention any."

Tamiflu (oseltamivir) for Influenza "Tuesday 2am chills, sweats, fever, horrible bodyaches, headache. Got in to see Dr on Wednesday 10am and tested positively for influenza. Took first dose of Tamiflu right after Dr's appointment and its now Friday 11am and I'm feeling different. I can actually get around the house no fever, sweats, chills, headache, etc. just still draggy and tired but still 2 days of medicine left. I will say definitely works!"

Tamiflu (oseltamivir) for Influenza "The price of this drug is ridiculous!!! So my physician wrote a prescription for Tamiflu $147 and for the new one dose flu medicine made by the same company with a coupon. With the coupon and my insurance it was going to be $90 for the new flu medication. The coupon stated that they would pay $60 and I would pay $30 plus what insurance did not cover, leaving the total cost at $150. For $150 I could be hospitalized. That is my hospital co-pay. Therefore it is cheaper to be hospitalized than to get medicine needed to treat an illness. As a healthcare professional, this is what is wrong with our healthcare system. Big pharmaceutical needs to be taken down!!!"

Tamiflu (oseltamivir) for Influenza "Apparently Tamiflu (I purchased as brand) is only affective if taken 2 days at first sign of symptoms. But I never have time to visit a doctor (I’m an airline pilot), so my doctor gave me a box of Tamiflu, to use at first sign of flu symptoms. These pills are amazing. They work extremely well for me. Paired with Advil, Tylenol, and Sudafed, these little pills are their weight in gold. Totally worth it if you recognize the first basic signs of the flu and act on them fast. I noticed there’s a 12 hour window to consuming Tamiflu, if I want any success from it."

Tamiflu (oseltamivir) for Influenza "This was prescribed to my 17 month old son and he started behaving weird when he is sleeping. He would wake up every 20 mins screaming and sometimes he would be scared of me. I was not informed about the possible side effects. I decided to google Tamiflu and thats when I realized that it was responsible for my baby's odd behavior. Drs should warn parents about these side effects before they write the prescription."

Tamiflu (oseltamivir) for Influenza "I have flu many times over the last half century, but last year, even after flu vaccine, was the absolute worst. This year symptoms hit me like a ton of bricks on a Friday afternoon: pulse of 120, fever of 102, terrible chills and body aches. I headed straight to a clinic (doc's office was closed) and got a prescription for Tamiflu, which I started immediately. When I awoke the next day my symptoms were much better. I still had the flu, but a mild case."

Tamiflu (oseltamivir) for Influenza "Tested positive for H1N1 on Monday after feeling MISERABLE! Was unable to breathe from my nose, sore throat, back ache, terrible cough that made my ribs burn. Started the meds Tuesday & now (Wednesday afternoon) I'm feeling tons better! Achiness is gone, breathing easier, not quite so tired. It was expensive but totally worth it in my opinion."

Tamiflu (oseltamivir) for Influenza "My 5 yr old took tamiflu for flu. On the 3rd day he starts being super clingy and paranoid. Scared to go into the bathroom alone because "a spider might get him." Has trouble sleeping, talking in his sleep. 4th day has a nightmare at 2am, was acting like something was choking him, struggling/scratching at his own neck. I woke him, he says the grass is trying to choke him. Neck had scratches from clawing at himself. Could not get him to go outside 3 days later. It has been 2 months and his behavior has not been normal since. He won't go outside alone. He is afraid of things he wasn't before like caterpillars. Doesn't like closing his bedroom door if he is alone in the room. Nothing happened to cause this behavior. Only difference was the flu and tamiflu. Asked my doc about tamiflu being the cause and was basically told "not to believe what I read in some blog." But I strongly insist that there is nothing else to explain it. Kids don't just have life altering mental episodes for no reason!"

Tamiflu (oseltamivir) for Influenza "My husband was prescribed Tamiflu for influenza. Immediately, upon beginning the script, he got diarrhea. Everything he ate, including popsicles, would require an immediate trip to the bathroom. His doctor advised to continue the script anyway, so after two days of constant bathroom trips, he stopped eating for the remaining 3 days of script. The medicine also caused insomnia for 48 hours, and feelings of depression (which my husband is not normally subject to). I cannot imagine a scenario where I could recommend this medication. And nobody in our family will take it again."

Tamiflu (oseltamivir) for Influenza "I started taking tamiflu on the 3rd day of having the flu. It actually made the flu symptoms go away by the next day but the side effects are not worth it. I got so dizzy I couldn’t even stand up. I had cold sweats and nausea from the dizziness. I also got horrible abdominal cramping and diarrhea. I stopped the medication after the 3rd dose because I couldn’t take care of my daughter or myself from the intense dizziness. I would not recommend this medication."

Tamiflu (oseltamivir) for Influenza "Caused me painful nausea and then vomiting about 30 minutes after taking it. Had to use a suppository promethazine to relieve nausea. Took it again about 5 years later for another flu - same thing happened. Just made me feel worse, but it worked for the rest of my family."

Tamiflu (oseltamivir) for Influenza "Awoke with flu Monday morning...full on symptom’s of aches, fever, chills and sweating and plenty of dry coughing. By day 3 of the flu and still having a fever, I went to see my doc who prescribed Tamiflu. I’d never taken nor heard of it. Took the first dose yesterday and felt the same with two huge sweats . Awoke this morning feeling much better than previous day. Took 3rd dose of Tamiflu this morning and by now, mid-day, I’m feeling like I’m quite a bit better. Residual body aches and occasional cough, but nothing like previous days of the flu ! And no side effects whatsoever."

Tamiflu (oseltamivir) for Influenza "After two days on Tamiflu, I feel worse. The nausea, heachaches, and insomnia are unbearable. I also had horrible stomach cramps after the first night of taking this med. I have a loss of appetite and a weird taste in my mouth as well. The nausea is hideous. This medication is much too strong. I feel more sick having taken Tamiflu. I will stick to ibuprofen and ride out the rest of this flu. I do not recommend Tamiflu. Seems a bit risky to me."

Tamiflu (oseltamivir) for Influenza "I got the Flu and it hit me hard and I fainted and was so sick so I went to the ER. They tested me and I had Influenza B. They prescribed this antibiotic and the first time I took it I felt completely fine, however, on the second day I took it I got intense nausea and vomited to try to feel better. As soon as I started vomiting I got a nosebleed as well. I spent the night vomiting continuously and after that I couldn’t keep anything down for about 2 days, along with intense pain in my abdomen. This felt worse than the actual Flu"

Tamiflu (oseltamivir) for Influenza "Daughter was swabbed for the flu, which came back negative. However, based on symptoms, Urgent Care doctor still prescribed Tamiflu. She took three pills and literally began sleeping in the bathroom due to the constant diarrhea. Was told to just take pepto bismol. By day two she had blood in her stools, sweating, and stomach/abdominal pains that have been so bad that she can't get out of bed. She's had a constant headache, to where she just needs to stop and hold her head. On day four since stopping the medicine and is still it eating, still occasional diarrhea and the stomach pains are still present. I have been forcing liquids to make sure she doesn't get dehydrated from the lack of eating and constant diarrhea. Never again will I allow her to even accept this medication from a doctor! This medicine needs to be taken off of the market!"

Tamiflu (oseltamivir) for Influenza "After mild symptoms of upper respiratory symptoms the day before, I awoke the next morning with 103.9F temp and thinking I might need to be hospitalized. My primary care physician had 1 sick visit slot open (thank goodness). By history and physical she diagnosed the flu and prescribed Tamiflu. I took the first dose and went back to bed. 6 hours later I felt better and no fever. I agree it is miraculous!"

I vomited about an 1 1/2 after the first two doses. I was tempted to stop the medication but did not. I am feeling nearly 100% better and it is now day 4. I would definitely take this again."

I haven't felt like eating, so luckily I couldn't vomit. It sort of made me dizzy and it gave me a headache. I wouldn't recommend the medicine to anybody."

Tamiflu (oseltamivir) for Influenza "Over the course of 6 hours I went from mild neck pain to full 9/10 body pain, splitting headache, and 101.5 fever. Stopped at urgent care where I laid for three hours. Tested positive for Flu A. Given tamiflu, and recommended to alternate Advil and Tylenol. Took first dose on an empty stomach, had a night of cold sweats (but still slept well), and woke up with only a mild headache and low grade fever. Having not eaten for 24 hours, took the next dose with soup and crackers. I’m now on dose 6 of 10. Fever and headache are gone, even without Advil/Tylenol. No other symptoms have cropped up—GI or respiratory. I’ve been mostly in bed resting for two days straight, but feel good enough to join the family again today. Tamiflu was a true godsend. I thought that was it for me two days ago and now I’m on my feet again like nothing happened."
