    Amoxicillin for Page strand angina

    I have amoxycillin 1000 mg on thursday because of a side-hunger gangrene. I was already much better the next day and the sore throat was minimal … on the second day I got headache and neck pain, I was always dizzy, in the evening I noticed a slight rash in the face, well, and today I have on the hands rashes and on the face everything is full … like a strawberry, in addition, my hands are swollen, and just today we celebrate our anniversary in the noble restaurant … nevertheless, the effect occurs very quickly, yet I would do not recommend, too many side effects and above all so fast.

    Side effects: Headache; Skin rash; Dizziness

    Amoxicillin for Tonsillitis

    Amoxi 1000 – 1 A Pharma. 7 days ingestion, 3 times a day. The first two days it was still alright, have always tolerated the drug before. Then two days after taking the first red spots. But left quickly, so I did not think much of it. After two days red spots again, this time not many small but two huge neck and chest. So to the pharmacy (since weekend), get cetirizine. Has also brought something first. Amoxi continued. Then the next day bad headache, mild respiratory problems and again slight red spots. But they remained small, so continued to take cetirizine. On the last day of intake (today) I wake up and am full of red spots and pustules, even on the scalp and hairline, the center of the whole were mainly the thighs. It also itched, especially on the head. Then I go straight to the doctor and got a cortisone injection. I should take cetirizine. And probably never again amoxicillin. The tonsillitis is incidentally only almost gone, sometimes still visible. Now get another antibiotic for the next two days. Enjoy with caution. In itself, it has always helped me well, but you should be well aware that at some point you can simply allergic react. And then hurry is needed, that could have been worse.

    Amoxicillin for Helicobacter pylori gastritis

    Immediately: Metallic taste; About 2 hours after taking the headache began, which remained more or less the whole time; severe pain when moving the eyeballs; from the second night (after the third dose): insomnia and about 6 hours after taking the tablet severe nausea that lasts about as long. In addition, extreme dry mouth and occasional muscle pain in the legs, so that I could no longer sit or lie down. The side effects are due to clarithromycin, as I have previously received and tolerated penicillin. I already took omeprazole one week before and did not experience any serious side effects (except bloating and muscle pain in the first few days). Since the side effects increased after each tablet intake and I was finally in a terrible condition, I stopped the therapy after the 4th dose. After about 3 days I was fine again.

    Amoxicillin for Tonsillitis

    Hello, had tonsillitis (Bacterial) and therefore got my doctor Amoxicillin 1000 Heumann prescribed. Since I’ve never been allergic to medications before, I figured it would stay that way. Everything went well until the sixth day of treatment, my tonsils were no longer inflamed so much for the success of amoxicillin. But at 9 o’clock in the morning I noticed a rash in the area of the bronchi and shoulders. Around 12 o’clock, this rash spread to my whole body and started itching. A terrible feeling … :). Anyway, I got a headache and a strong fever with chills, etc. Little by little my face and neck swelled up so that I could barely breathe. At this time, I was already on the way to an emergency clinic, where I was treated immediately. A doctor said that this side effect can certainly be life-threatening. If the side effects are left untreated, the respiratory tract can gradually swell! So much for the risks. I therefore recommend this product to anyone who is previously aware of what he is allergic to, for all the others out there please do not take any risk because that can quickly end bad!

    Before and after my wisdom tooth surgery, I was given the antibiotic amoxicillin to prevent inflammation. After taking the drug for the first time, I had such a severe headache on the 2nd day that I had stopped taking the tablets on the 3rd day. After my op I should take the drug again and now I have not only problems with headaches but also with loss of appetite weight loss and a kind of drowsiness. Add to that flatulence and dizziness …
