Doxycycline 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.

Sun, 07 Jun 2009
I was taking Doxycycline for an MRSA staph infection. I had tightness in my chest and worsening difficulty breathing, sore tongue, burning palms and soles of my feet, and extreme exhaustion. At the end of my 9th day on the medication, I had excrutiating headaches, I was unable to eat and drinking more than a sip of anything made me unable to breathe. I didn't even think about this being a side effect of the antibiotic. It was really scary. I stopped taking it two days ago, and I still feel somewhat bad, but I can at least breathe again now.
Sat, 15 May 2010
The doctor had prescribed me 100 mg Doxycycline twice daily for 14 days. On 9th day of medication, I had itching in different parts of my body. Then I consulted the doctor but he asked me to continue the Doxycycline and complete the course. To control itching he gave me antihistaminic drug for the remaining medication period. Even after completing the course of medicine I had little bit itching for one more week.

I was taking them as an anti-malarial. Caused a duodenal ulcer and a bleed on the brain, either of which could have killed me. Both nearly did, I had 3 months in hospital and 8 operations before I was discharged. I will probably never be properly well again.

I am 51 and have not had a period in 2 years. 2 days ago I had some breast tenderness and this morning I woke to classic menstrual bleeding with abdominal cramps.
