Can you answer these questions (Ask a question):

  • Last night went to hospital as i was shaking and dizzy scared it was after my third dose of avelox. is this a side effect? i'm scared to take anything even my regular medications today was shaking
    Taken pain mess for years got chest infection was given avelox three days ago. Last nights dose I started shaking couldn't breathe so shaky yet I am dehydrated too. I had woke up drank coffee then took my mess regular and started shaking all over again. Drank three glasses of juice and two of water felt better but still off. I only take one dose of avelox a day and think I should stop it, should I?
  • Seizure after an epipen injection (1 answer)
    I am allergic to EVERYTHING, so I usually pre-game with benadryl and wait out the uncomfortable side effects, but this time my tongue started swelling up and I was having trouble breathing so I went to an ER. About 5-7 minutes after they injected me in the thigh with an epipen, I was in mid sentence when I started having strange sensations and tremors all over my body. The injection spot, which is incredibly sore and feels like they hit my femur) suddenly became very warm and I could feel it spreading out quickly. I could hear people but I couldn't speak, everything clamped up, I couldn't breathe and I felt very confused and forgot what I was about to say to the nurse. The doctor caught the tail end of it and claimed I was having a panic attack! I heard both the nurses say that they thought it was a seizure. This happened to me once more a few yrs ago with an allergic reaction, but it was from the nurse pushing in the benadryl too quickly, which made my hands curl up like T-Rex and my eyes rolled back into my head. Is there such a thing as being allergic to epinephrine or has anyone ever experienced a seizure/stroke like reaction after being administered Epipen or Benadryl ?
  • Can thyroid problems bring on anaphylaxis often?
    70 yr old previously stong female: Suspicious of thyroid history. Fatigue, skin, hair changes, slightly swollen, tender tongue at all times. In the last 6 months I've developed food related anaphalaxis. Getting serious, 3 E.R. runs in last 3 months....packing 2 epipens at all times. Endocrinologist apt not until mid December. I can't seem to stay clear of anaphalaxis long enough to get to the Allergist's for those blood tests.

    Any one else gone this route?

  • Happened to me- allergic reaction to rogaine
    Within the first week of usage, I began to have leg cramps, facial swelling, tightness of breath, chest pain, anxiety, and chronic headaches. Even with allergy medicines and aspirin, nothing seemed to help. At first, I felt it was though it was just simple allergies until I woke up one morning with my face so swollen that I could see my skin around my eyes without looking in a mirror. My throat began to swell to the point it was difficult to swallow. I immediately went to the ER to receive a shot and sleep all day with Benadryl. The following day, I have redness in the skin and hoarseness. The doctor told me too never touch Rogaine again or I would end up in the hospital (or worse).
  • Cephalexin 500 mg caused allergic reaction (1 response)
    I developed a rash that quickly turned to painful, itchy blistering after taking cephalexin 500mg capsules for only 2 days (the prescription was for 10 days). The rash was on my hands, legs, back, & arms. I was sent by my doctor to the hospital emergency room. diagnosed as an allergic reaction to cephalexin. treated with steroids & another antibiotic. this was one of the scariest episodes of my life. I hope people are reporting this type of problem.
  • Avelox with prednisone and nabumetome = disaster
    I was prescribed that combination of drugs in January 2013 when I went to my family doctor with a bad chest congestion and painful knees. After starting on the drugs, I got a severely painful neck and thumb and noticed some tingling in my left foot. I took the whole course of the avelox and prednisone, though I discontinued the nabumetome. I kept getting weaker and weaker till I could hardly walk. I ended up in the emergency room and was first diagnosed with Rhabdomyolysis but rushed to a bigger hospital for further diagnosis and treatment. I was close to needing blood, my kidneys were shutting down and I could barely walk. I was so weak! My right hand and left foot went "to sleep" and still haven't woken up. ( as of October 2013)

    After many, many tests, they came up with a tentative diagnosis of vasculitis and myositis.

    Then I had a kidney biopsy which confirmed the vasculitis and I was immediately treated with chemotherapy -- cytoxin for 6 months.

    IAlthough I do feel much better, I am still suffering and taking drugs for the vasculitis and I am told that I may go into remission, but it could flare up again anytime. I am convinced that it was the drug combination that caused all this. I had been feeling great and had a daily walking routine of walking 2 to 5 miles per day, and no other complaints.

    The nephrologist did say that while it might be that the vasculitis was drug induced, it didn't matter because I have it and he's treating it and would be doing it this way no matter how I got it.

    When I told my family doctor that I thought it was the drug combination that caused my problems, he seemed surprised and really no discussion. I told them to put it in my medical records to NEVER give me a flouroquinolone drug again.

    Yesterday when I went for a blood test and urinalysis ( which I was doing biweekly, but now every 6 weeks), it showed that I have a UTI and guess what the family doctor called in a prescription for? Cipro!!!! And he knows I'm still on prednisone and have only 30% kidney function!!!!!!

    While I am not a litigious person, this really makes me so upset!!! I don't have the money to try to sue, but if telling my story will help keep unsuspecting people from the horrible damage this has caused, I feel obligrdmtomspeak up. I have had a terrible year. And I'm still not okay. And the drugs 'm taking make me susceptible to other problems. I'm still all puffed up from the prednisone. A couple of weeks ago I decided to try going for walks again, hopefully to lose some of this weight and build up my strength. It is so hard for me and my left foot hurts so bad. My legs feel so heavy it is a real struggle to walk a mile. But at least I can. When I was at my sickest, could barely walk to the bathroom and I could not get up from the toilet without using my arms to pull myself up. I couldn't go up the two steps to get into my house without help. I couldn't go upstairs to my bedroom for months.
  • 43 with chest tightness & can't take full breath
    First morning after taking Avelox the night before, I felt something odd in my chest...thought it may have been the neck infection carried down. After third dose, chest pressure felt like a baseball pushing under my sternum/chest area at the level under my breastline. I could not take a full breath without being stopped by the pain in that area feeling like the baseball would burst through my chest. Upon normal going up normal stairs in my house that I do often, I felt short of breath and had to sit down. I am a healthy, 5ft 5in in height 120lbs without any health problems. It did however work well on my infection, but I am worried that it will be worse on my chest if I continue the 4 through ten days and am waiting for my physicians reply.
  • Anaphylactic shock from fish oil
    Yes I went into Anaphylactic shock after taking fish oil. It was just a matter of a few minutes when my hands and feet started itching and then my throat closed up. I could not breathe and 911 was called. I spent 4 nights in the hospital, the first 24 hours vomiting and loose bowels. It was the most frightening experience i have been through. Please post this because there are many so called experts on the internet who claim it is not possible to overdose on Fish Oil. I believe fish oil is good for some people, but it was not good for me that one day as I had taken it several times before. Please feel free to contact me with any questions on my personal experiance with Fish oil.
