Cephalexin Malaise Causes and Reviews


What is chronic fatigue syndrome?

Chronic fatigue syndrome (CFS) is a serious, long-term illness that affects many body systems. Another name for it is myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). CFS can often make you unable to do your usual activities. Sometimes you may not even be able to get out of bed.

What are the symptoms of chronic fatigue syndrome?

CFS symptoms can include

  • Severe fatigue that is not improved by rest
  • Sleep problems
  • Post-exertional Malaise (PEM), where your symptoms get worse after any physical or mental activity
  • Problems with thinking and concentrating
  • Pain
  • Dizziness

CFS can be unpredictable. Your symptoms may come and go. They may change over time - sometimes they might get better, and other times they may get worse.

Who gets chronic fatigue syndrome?

Anyone can get CFS, but it is most common in people between 40 and 60 years old. Adult women have it more often that adult men. Whites are more likely than other races to get a diagnosis of CFS, but many people with CFS have not been diagnosed with it.

What causes chronic fatigue syndrome?

Scientists don't know what causes CFS. There may be more than one thing that causes it. It is possible that two or more triggers might work together to cause the illness.

How is chronic fatigue syndrome diagnosed?

CFS can be difficult to diagnose. There are no tests for it, and other illnesses can cause similar symptoms. Your health care provider has to rule out other diseases before making a diagnosis of CFS. He or she will do a thorough medical exam, including

  • Asking about your health history and your family's medical history
  • Asking about your current illness, including your symptoms. Your doctor will want to know how often you have symptoms, how bad they are, how long they have lasted, and how they affect your life.
  • A thorough physical and mental status exam
  • Blood, urine or other tests
What are the treatments for chronic fatigue syndrome?

There is no cure or approved treatment for CFS, but you may be able to treat or manage some of your symptoms. You, your family, and your health care provider should work together to decide on a plan. You should figure out which symptom causes the most problems, and try to treat that first. For example, if sleep problems affect you the most, you might first try using good sleep habits. If those do not help, you may need to take medicines or see a sleep specialist.

Strategies such as learning new ways to manage activity can also be helpful. You need to make sure that you do not "push and crash." This can happen when you feel better, do too much, and then get worse again.

Since the process of developing a treatment plan and attending to self-care can be hard if you have CFS, it is important to have support from family members and friends.

Don't try any new treatments without talking to your health care provider. Some treatments that are promoted as cures for CFS are unproven, often costly, and could be dangerous.

Cephalexin Malaise Reviews

Thu, 21 Jun 2012

I also face critical situation low blood pressure,Headache and diarrhea. So i decided to quit and decide not to use like that medicine again.

Mon, 07 Nov 2011

One more pill to go before I finish my dose of Cephalexin for Cellulitis. First of all, the symptom worsened within the first 24 hours - both the doctors failed to tell me that. It did eventually work and about 48 hours later, the swelling and redness from Cellulitis started to decrease. The side effects were not severe, but, at worst, I experienced nausea, stomach ache, diarrhea, and depression (followed by the most whacked out dreams). This is not quite the drug from hell but I am very much ready to finish my dose.

Fri, 16 Mar 2012

After taking Cephalexin I experienced nausea, vomiting and headaches which 800mg of ibuprofen couldn't control.  The sweating (head to toe) was profuse and disconcerting.

Sat, 31 Mar 2012

After a double treatment of Cephalexin 500mg 4 times a day, I am still experiencing intestinal discomfort and loose stools. I also get a lot of gas, bloating and it makes it hard to go anywhere because of the sudden diahrrea that goes with it. I will NEVER take this drug again!

Sat, 18 Jun 2011

I am currently on Cephalexin for a kidney infection. I have so far suffered from joint pain, headaches, unusual vaginal pain and itching, dizziness and discovered a sore throat this morning. I plan to finish my dose but it seems like I'm suffering worse now than with my kidney infection.
