Amoxicillin and sinus infection

I started on a 10-day course six days ago for chronic sinus infection. Strange things started happening but I didn't connect it to the drug at first... first night, I kept waking up and having weird nightmares, very unusual for me. On the second day a headache from hell kicked in and lasted about two days. This was really awful, just bearable, but I still didn't connect it to the amox until a friend sent me the link to this page. It helped to know what was going on because the doc told me NOTHING, which really ticks me off. I've also been feeling very, very down and hopeless, also not like me, and the last couple of days I've had strange aches and pains all over my body. These feel like they're deep inside and unlike anything I've ever experienced. I'm a male in my 50's and generally avoid drugs and chemicals of all kinds. This just reminds me of what's wrong with doctors... all they know how to do is prescribe drugs and operate. Forgot to mention the constipation followed by diarrhea on the second and third days. Ugh.

I am very reluctant to take any medications, but needed something for a sinus infection that wouldn't go away after 2 weeks. Received 10 day dosage. Drug worked to clear it up, but experienced a noticeable oncoming of depression and emotional detachment from life. This drug may not be tracked for psychological side effects, which might explain the lack of forewarning by doctor's et al, but it was a clear cause and effect in my case.

I went to the doctor two days ago, prescribed with amoxicillin for sinus infection (250mg 3x/day). I have asthma as well so the infection has hit me pretty hard. After taking my 4th dose last night there were noticible changes in my sinuses for the better, everything was clearing up, still a runny nose but now clear instead of green/yellow. Before taking the meds I had a terrible itchy throat as well from all the drainage and that is gone as well even though I'm still draining. Side effects last night were no fun though. I've had no appetite as it is, so I eat light before taking any meds at the least, had a yogurt and an apple before taking the meds and I don't know if it was the combination of food and antibiotics or just side effects, but I got a terrible feeling in my stomach like a burning sensation and was also nauseous...wasn't able to sleep for another 4 hours because I was going back and forth to the bathroom. Finally did get to sleep and woke up 6 hours later having to use the bathroom immediately upon waking and that was very unpleasant. A very high yellow diarrhea, and smelled horrible. Still not feeling better, have no idea what to eat and approaching my next dose...gah!

Horrible experience with amoxicillin, which was prescribed for a nasty sinus infection. Major nausea, fatigue, feeling lightheaded and dehydrated. All I wanted to do was to sleep. Missed 2 weeks from work. The nausea was completely debilitating. But curiously, get hungry at the same time was feeling nauseated. When I do get some food, I have to force myself to eat it. Also had major headaches. Got sort of paranoid that something else was seriously wrong with me!
Have been off amoxicillin for a little over a week. Feeling VERY depressed and hopeless. I want so bad to get back to my normal life, but it is like I have no energy or desire to push on. I have to literally FORCE myself out of bed and to work. Very concerned here and do not want to have to start taking an antidepressant. Does anyone know how long these effects will last or what I can do? Doctor gave me an additional prescription for Cipro, but I am afraid to take it because I feel like I am trapped in a vicious cycle and these feelings will only get worse. I am not used to taking meds!!

sinus infection: 500mgx2 a day, on 7th day feel a lot better, but have also experienced a lot of side effects like others, worse for me is dizziness and fuzzy mind, want to sleep more, not a headache, just not feeling normal light headed as if i could pass out at times! obviously strong stuff!

My Husband has taken this all his life of course like many of us have as a child and teen. He is now 27 and started this on Tuesday for a sinus/upper resp. infection. Evening of day 1 with first dose and day 2 nothing. Day 3 he started itching and didn't know why. Day 4 lips, hands were swollen. Tongue slightly swollen. Hives started on shoulders and inside of thighs that night. Day 5 swelling down after starting benadryl but hives all over body or rash all day off and on. Day 6 back to the doctor who said that he had an allergic reaction and was now allergic to Penicillin.
Strange but it is true that you can be allergic even after taking it for so many years beforehand.

I was prescribed amoxicillin for a sinus infection. (3 x 500mg / day) The good news is that the sinus pain was relieved within two days. On the other hand, I developed several side effects, which seem consistent with other reports I've read on this site. These include the common complaints of diarrhea and upset stomach. In addition, after about two days I started to experienced symptoms of a fever, including general body aches, slight head ache, chills and skin sensitivity, especially on my back. The strange thing is, I don't have a fever (temp. 97.9F). These symptoms seem worse at night. I suppose I could have some type of virus along with the sinus issue, but it seems strange that the onset of symptoms was so coincident with the amoxicillin treatment.

i am taking amoxicillin for a sinus infection. the first night after taking amoxicillin, i had trouble sleeping, but when i did sleep, i woke up with night terrors/nightmares. i have been extremely moody and short tempered, which is unlike me. there is a constant mild headache and a bit of depression. i am on day 6 of 14 and very tired.

I was given 500mg Capsule of Amoxicillin for sinus infection. After 4 days on this med I am now getting all over body aches and pains. Not sure if this is a side effect of Amoxicillin or from the sinus infection. Either way I feel like hell. The Dr ruled out anything else, but I have chest congestion and headache and nasal congestion as well. It has abated some but taking a long time to clear up.

i feel like i have the flu (aches, chills, pains, fever,vomitting, upset stomach) but about 100 times more gloomy in my head and sleep barely feels comforting. this only happened after about 5 days on 2000mg for a nasty sinus infection.

Stomach felt real raw, nasusea,vomiting,and diarrhea. This was amazing to me because i was prescribed the meds only for a sinus infection.
