16 year old daughter diagnosed with Influenza, so her MD prescribed Tamiflu for her, 75mg. Capsules, twice daily for 5 days. He also prescribed my husband and myself Tamiflu, 75 mg. Capsules, once daily for 10 days. I am on numerous meds, but not my husband or daughter. My husband and I have experienced severe GI symptoms, insomnia, nightmares, and a strange feeling of "loopy"(per our daughter), "really different, so out of it" (per my husband), and I feel kind of out of it, but also noticed a big increase in my depression and anxiety and even something last night that I would describe as "brain spasms". Just wondering if anyone else has had any of these odd things with the use of Tamiflu?
Anyone else have terrible negative side effects with the use of Tamiflu?

I was prescribed Tamiflu two days ago and it was my first time. After the first dose I noticed vast improvement in my symptoms, but that night I was up for 2.5 hours and my Fitbit showed a dramatic increase in my heart rate. I thought it was just my body fighting the flu. The next night I was up for 5.5 hours, had heart palpitations, brain fog and was really anxious (a rarity for me). I searched for side effects of Tamiflu and saw that insomnia and anxiety are big ones. I immediately stopped taking it and, although I am coughing a little more, overall I feel so much better without it. My nausea is much better, too. I will never take this drug again!
I was given Tamiflu 75mg and Azithromycin 250mg on my 2nd day of having the flu, after taking the 1st dose at 1st i thought it was the flu that was making me feel my brain foggy and dizzy so on my second day of taking Tamiflu my symptoms became horrible. Brain fog, dizziness, diarrhea, headache, anxiety but the worst part is everytime i try to get up from bed i feel like I’m drunk! I’ve only taken 3 pills of Tamiflu and 2 of the Azithromycin but these side effects are so horrible I’m stopping this medication regardless. I already suffer panic attacks and high blood pressure i can’t afford to be this sick. This pill should be taken off the market!!
I started on Tamiflu on Monday night and stopped after taking just 4 pills on a Wednesday night. I generally have no depression problems at all but began feeling sad and hopeless within those 2 days to the point where I was having a panic attack and went into the bathroom and told my husband to get out of the shower bc I was having a panic attack and needed help ASAP! He rubbed my back for about 15 minutes and it calmed me down a lot. I felt better the next day, back to normal thank God! Have hope, but I’ve warned my kids to never take this med. I am 48.
Very bad chronic mental illness induced by tamiflu:
I took tamiflu on January 18th, 2018. After my first dose, that night, I had immediate bad mental problems. Panic attacks, perceptual disturbances when I went to walk it off, and feeling very off centered like something was wrong with my mind. I stopped taking the tamiflu after the second dose and received some relief and thought I was going to go back to normal. I did not. Over the next few weeks anxiety each day grew from an acute burning in my mind to massive feeling of apprehension, and discomfort with every thought. I had to drop out of school because I could no longer read, and I was experiencing horribly intense pain and fatigue in my mind while working, and had to stop working as well. After a few weeks, I was totally confined to bed rest with severe anxiety , fatigue, insomnia, unable to eat, and when the pain became so bad I had to go to the ER and then a psych ward.
This is weeks after I took and stopped taking the tamiflu. I now take Klonopin and an SSri lexapro to relief the anxiety, but my mind has not been fixed. The anxiety pain is lessened, but just like before I took the Klonopin, my thoughts don’t ‘function’ and I’m stuck in bed rest like a vegetable. Ive been seeing a psychiatrist and therapist for over a year, having tried every type of psych medication, and the conclusion has been that every type of psych med ( antipsychotics or mood stabilizer, or anticonvulsant) only aggravates my symptoms and make it worse . The only form of some relief I get is from the Klonopin and lexapro, but I’m still left without a working mind and I’m still in a lot of ‘mental pain’. Doctors say to describe the mental pain, and I’m unable too. Just the experience of pain and suffering, and that it’s not physical. The psychiatrists are quick to diagnose me as schizophrenic, but yet I have no delusions or hallucinations, or any positive response to antipsychotics.
I was a perfectly functioning engineering student , living largely independently and working a part time job, with summer jobs lined up, and no mental health issues, and suddenly I take 2 doses of this tamiflu, and my mind deteriorates to a critical and chronic amount of anxiety that my thoughts don’t work and I’m in severe pain, and it has continued exactly like this for 2 years now. No change in my experience for 2 years. The exact same symptoms and effect that started after taking tamiflu.
I am now going to a university hospital outpatient program to hopefully get some help, but I would greatly appreciate if anyone learns more about oseltamivir and it’s effects on the central nervous system or any other insights or breakthroughs that might provide a solution to my mental symptoms.
Thank you,
Sam
@mattman85 how do you feel now? Did the anxiety dissipate? Are you back to yourself?
I was prescribed Tamiflu 75mg capsules within 2 days after the onset of flu symptoms. Was supposed to take twice a day for 5 days. Stopped taking after 3 days due to side effects (nausea, headache, skin rash, difficulty swallowing). I also feel like my mind is foggy and feel a bit loopy. The other side effects have subsided since stopping the medication 2 days ago. It concerns me others have also reported problems with mental alertness and depression that seem to last long beyond stopping this drug. I am a generally a pretty healthy person. I would not take this drug again.
I got the flu the day after Christmas, and got prescribed Tamiflu. I took 4 of the 5 days worth. A day after I stopped taking it, I started having horrible insomnia and anxiety. I still, 2.5 week later, can't go to sleep at night unless I take 3-4mg of melatonin, or nighttime cold and flu (non-benadryl antihistamine). My anxiety is kind of going away, albeit slowly. This irrational anxiety and insomnia are ridiculous. I know it's got to be the tamiflu because I've never had any problems falling asleep until after I was given that for the flu..
How do you feel now? How long did it take for your anxiety to go away?
I’m 5 weeks pregnant and I was prescribed to take Tamiflu(Oseltamivir) to treat it or to prevent it. I was doing good taking them other than I I felt my head heavy idk how to explained but it was weird. But yesterday morning I took my last pill and started feeling anxiety and depression all I wanted was to cry, well till today I’m feeling really sad like depress :/ . & I know it was a bad reaction of the medicine. I just want to be me again . Worst experience ever .
How do you feel now? How long after did you start to feel yourself again? Please answer. I need some good news.
It’s going to be 1 month and I still have depression. My anxiety is kinda going away I feel more bad in the mornings. I just hope one day I’ll be back to normal. It’s horrible feeling like this. @nicole how you doing ?
I took my last pill about 2 and half months ago and I just started getting a tad bit of depression. I am so upset i thought i was over this crap. It started with severe anxiety/panic and brain spasms, they slowly went away and now all of a sudden i am having depressive symptoms. FML
I am still feeling anxious in the mornings. I have anxiety and panic disorder, but it was under control with taking Zoloft. Took the tamiflu and it’s almost rendered my SSRI ineffective.
So, I typically have anxiety in the morning. Ruminating thoughts, extreme worry, restlessness. I get crying spells throughout the day.
I feel like it’s slightly improving. Today is day 8 after I stopped tamiflu.
Maybe you are experiencing brain zaps from stopping your SSRI med?
Oh so you had some preexisting anxiety and depression? I had none, never taken any medication for that until this happened to me with the tamiflu, i took lexapro for about 10 and had to stop as it was making me worse, that was about a month and a half ago. I had the brain zAps as soon after started on the tamiflu they are less severe now and they are more like brain pulses/pressure.
How’s your anxiety doing now? And when when you’re last dose of tamiflu?
No.
Absolutely have not had a negative reaction from the anti flu medicine.
Thank goodness I found this site! my mother of age 92 was given 4 doses in the hospital and she is having auditory and visual hallucinations since dose one. She has become aggressive and agitated. She is acting goofy and loopy. She won't sleep and does random things such as talking to the furniture. She has become OCD about counting her pills and jumps put of bed to check and recheck her meds.
I did a lot of research and the only new meds are Tamiflu and nothing good is written about it.
I'm taking a chance but I'm going to stop giving it to her.
How long will this last? I have to go to work on Monday and she won't let me sleep.
I am so releived i found this page. After 5 days on tamiflu i started experiencing sever anxiety, and insomnia due to what could be best described as short vivid dreams or brain spasms. Im borderline depressed as i though my mental health was going to start deteriorating but this page has given me hope. Its been one week since i stopped taken tamiflu and still have these symptoms. I do still have some flu symptoms such as sinus congestion so maybe i still have some tamiflu in my system.
This has been the worst experience of my life.
How are you doing now? I hope you answer
Hi Janie, its been about a month and a half and I am better now. For me, it got worse before it got better, it didnt help i ended up taking SSRI’s and trazodone to help with my anxiety panic attacks. I eventually developed mild depression because i was not getting better and it was very frustrating. Around 3 weeks ago, as soon as i stopped all meds I noticed a significant improvement. I still have brain zaps( shivers, pulses, pressure) or whatever you want to call it but little to no anxiety or depressive symptoms. Hope this helps
How long did it take til you let normal?
I took 1 dose 2 days ago and am having panic attacks, sleeplessness, and depression. I need it to go away or at least light at the end of the tunnel. Whoever is saying that these side affects are false are most definitely mistaken. 32 year old man with average health.
I know I know how you felt. Do you feel better now? I hope!
How are you feeling now?
How are you feeling now ? I need help.
Kbrandt, I googled “tamiflu mini brain explosions” because i couldn’t explain the weird symptoms i was having. Also have had weird disruptive dreams, not quite nightmares, more like stress dreams, as well as insomnia. Did you complete the full course? The brain spasms are concerning. Not sure if i should keep taking it! My fever is definitely better and i feel better overall after just 2 pills.
I am so scared I've been having bad adverse effects for 4 months now after taking tamiflu
How are you feeling now? Hope you answer
I was 8 weeks pregnant when I had to take Tamiflu for flu like symptoms. All the time I was taking it, I felt close to tears and very depressed. It was unexplained. I had no reason to be so. As soon as I stopped taking the drug, I was back to normal.
So the depression went away as soon you stopped taking the medication? I’m pregnant and I took Tamiflu too and it’s almost going to be 1 month and I’m still depressed
