Be careful - Flucloxacillin can make you feel very unwell!

Posted , 12 users are following.

I have just started a course of these and took my first capsule at 16.00 0n 21/8/08, an hour before food / on an empty stomach. At 20.30, I suddenly had severe heartburn followed by sickness and diarrheoa, which lasted until 01.00. I remembered that this happened the first time I took these and was advised then to take with food. So that is what I'm doing from today. They were still effective last time but at least I did feel so ill. I am hoping they will be OK this time round too.

    I had started the course of four tablets every 24 hours. when the first tablet was taken i felt fine but after that one time , each flucloxacillin pill has caused me extreme discomfort and mild/high pain.

    I had trouble breathing (very short of breath), i could feel the path which the tablet took and as the tablets flowed through my body i felt different amounts of pain. i was drousy and felt sick , yet as this went on my illness (luckily!!) decreased.

    I was given a course of Floxacillan 500mg 4 times per day for an infected toe nail. The toe was very painful and I could not get my shoe on. I started the course on 23rd of December right in the middle of the holidaysAfter taking 3 pills I had the worst bout of indigestion. This happened on Christmas day and so there was not a lot I could do about it. I did not relate the indigestion to the antibiotics and so I carried on with them.

    After taking them for three days and having indigestion consistently, I eventually put two and two together but as it was only a five day course I decided to persevere. However I then suffered the most horrible headaches and with only three tablets left I had to give in and end the treatment. My toe is still swollen andnever again will I take this particular antibiotic!

      I am only on day 2 of a 5 day course. I am taking 4 500mg per day, taking them on an empty stomach doesn't seem right as its given me terrible stomach pains and indigestion, my stomach is constantly gurgling like I need to burp. I fly to America on Saturday so I'm hoping I'll feel OK by then, keep your fingers crossed for me.

      Hi, I started on a course of these antibiotics for a chest infection, which it seems to be very effective for, however I have experienced sever pain in my stomach on day two of the course, despite taking them with meals, I am reluctant to discontinue course as they seem to be working, did you find any remedy to release the stomach pains.?

      I was prescribed the same medication for the same condition. I also work night shifts and took a capsule at work but felt like I was having a heart attack. I had chest pains, sweating, dizziness, stomach pains etc. is there any advice as to whether you can take flucloxacillin at night?

    Started on a course of these antibiotics, they seemed to be very effective in reducing the infection in my Lungs but on day two I experience the pains in my stomach, which then kept me awake for most of the night. I did take the tablets prior to taking food, are there any recommendations to reduce this effect, as I am reluctant to discontinue the treatment. ?

    Too much of anything is dangerous. Always be cautious and speak to the GP before taking certain dosages.

    A similar thing happened to me. After a few days of no symptoms my stomach started to feel strange but along with that came a tingling in my left and and face. I saw someone in the comments also mention a similar sensation saying it felt like a stroke. I got to 6 days out of 7 and had to stop. NEVER taking this medicine again if possible. It's been over 24 hours since my last pill and I am still feeling the side effects.
