Bactrim Pyrexia Causes and Reviews


A fever is a body temperature that is higher than normal. A normal temperature can vary from person to person, but it is usually around 98.6 F. A fever is not a disease. It is usually a sign that your body is trying to fight an illness or infection.

Infections cause most fevers. You get a fever because your body is trying to kill the virus or bacteria that caused the infection. Most of those bacteria and viruses do well when your body is at your normal temperature. But if you have a fever, it is harder for them to survive. Fever also activates your body's immune system.

Other causes of fevers include

  • Medicines, including some antibiotics, blood pressure medicines, and anti-seizure medicines
  • Heat illness
  • Cancers
  • Autoimmune diseases
  • Some childhood immunizations

Treatment depends on the cause of your fever. If the fever is very high, your health care provider may recommend taking an over-the-counter medicine such as acetaminophen or ibuprofen. Adults can also take aspirin, but children with fevers should not take aspirin. It is also important to drink enough liquids, to prevent dehydration.


Bactrim Pyrexia Reviews

Sat, 14 Apr 2012

I took one Bactrim pill and a little over an hour later was in the hospital. My heart was racing, I was shaking all over and I couldn't get my breath. I had been sitting quietly reading the paper when it was like someone injected me with Redbull! The medication had kicked in. Of course, the emergency room doctor said it wasn't the Bactrim. I had to follow up with a cardiologist and of course it wasn't the Bactrim. I then had to wear a heart monitor for 30 days and had no "episodes" while wearing it, and my echocardiogram was excellent. Still my doctor said it wasn't the Bactrim. So what was it, I asked? "I don't know." I do know. It was the Bactrim!! No other possible explanation. And, no, they both agreed it was not a panic attack.

I took my 10 year old daughter to the ER last Sunday, over a week ago, and they diagnosed her with Urinary Tract Infection. They prescribed Sulfameth / Trimeth or Bactrim. Since taking the medicine, she has had some symptoms she cannot explain since she is only 10, but she tells me she has body aches, constant headaches, and she also mentions that her heart hurts or jumps (palpitations). I also notice that her mood changes and that she has trouble going to sleep. Concerned, I went online and found that these are not listed as side affects. She doesn't get sick often, so I really worry about her. I decided last night to stop the medecine since she is very uncomfortable; I will not have her go thru this.
Mon, 24 Aug 2009
I am the person who wrote about my 10 year old daughter. Can Bactrim also have the symptoms of palpitations, body aches, stomach aches, trouble sleeping and mood changes?

I'm going through it now, I have so many hives all over me that some parts of me look like I have sunburn. I facilate between thinking quot;just shoot me knowquot; and quot;I hope this ends soon, I can get through this.quot; I itch so much. It's everywhere. I also developed swollen nodules in the back of my head (near neck) and sides of neck (lymph nodes), had headache, cough, swollen eyes, etc., went to ER last night and they fast tracked me in front of 40 waiting people! gave me prednisone (10 -20mg), z something (?) 2 tables? started with a 'Z', 2 benadryls and sent me home with a scrip for Predisone. They tole me drink a lot of water, so I was up all night itching and applying coritzone cream and going to the bathroom. I just took a luke warm bath, but it didn't help. I'd hate to think how I'd feel if I hadn't gone to ER, the rash has spread and itching is unbearable. I just lathered tea tree oil all over me having read it on natural health web site. Next I'll try chamomile tea bags, etc.

I had a bad reaction to Bactrim in 1987-I still don't have my health back. Now I have asthma and sinusitis, chemical sensitivities and immune problems. Don't take this killer drug under ANY circumstances.
Mon, 05 Jan 2009
Bactrim made my wbc dropp badly. I had all sorts of aches and pains. Since then I developped sensitivity to everything, I can't take any kind of drug. Carole have you found something that helped with the chemical sensiticity?
Tue, 02 Jun 2009
I took Bactrim for an infected Bartholin Cyst for four days. On the third day I started thinking very disturbing thoughts that were almost like they were not my own. It made me terrified of being alone with my son, afraid that I would hurt him. At night the thoughts would just come back and turn into anxiety attacks that made me sweat and shake. I was very upset that i had to find out on my own that I was experiencing side effects of Bactrim. None of my side effects were on the information sheet and that made me think my problems were because i wanted to think those thoughts. I will never take Bactrim again. And if you have a choice don't take it!

No problems for 2 weeks then bam! Severe itching, ringing in ears, heart palpitations, and the worst part is the intense, electric feeling in my leg muscles. My legs feel like they are being torn from the inside out. I stopped taking this junk 2 days ago and the syptoms are going away, but only a little. I'm athletic and this is really messing up my sports. I truly believe that many drugs are way more dangerous than they're telling us because it's so lucrative. I will never see a doctor again unless I'm about to die. This isn't the first time I've been srewed by doctors and their poisons. I say this and I'm married to a doctor!
