Doxycycline Fatigue Causes and Reviews


Everyone feels tired now and then. Sometimes you may just want to stay in bed. But, after a good night's sleep, most people feel refreshed and ready to face a new day. If you continue to feel tired for weeks, it's time to see your doctor. He or she may be able to help you find out what's causing your Fatigue and recommend ways to relieve it.

Fatigue itself is not a disease. Medical problems, treatments, and personal habits can add to Fatigue. These include

  • Taking certain medicines, such as antidepressants, antihistamines, and medicines for nausea and pain
  • Having medical treatments, like chemotherapy and radiation
  • Recovering from major surgery
  • Anxiety, stress, or depression
  • Staying up too late
  • Drinking too much alcohol or too many caffeinated drinks
  • Pregnancy

One disorder that causes extreme Fatigue is chronic Fatigue syndrome (CFS). This Fatigue is not the kind of tired feeling that goes away after you rest. Instead, it lasts a long time and limits your ability to do ordinary daily activities.

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.

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.
