Doxycycline Side Effects

By Dave / June 11, 2007

Doxycycline is an antibiotic and may also be prescribed to prevent malaria. It can have side effects and may put an additional tax on your kidneys and liver.

If you have any of the following side effects, contact your doctor right away:

difficulty breathing or swallowing

redness of the skin (sunburn)

severe headache

blurred vision

yellowing of the skin or eyes

light-colored bowel movements

loss of appetite

upset stomach

dark-colored urine



skin rash


extreme tiredness or weakness

decreased urination

stomach pain



itching of the rectum or vagina

sore mouth

Scary, isn’t it? The pharmacist especially warned me about being sensitive to the sun. I wore a lot of sunscreen when I went out. I experienced an upset stomach and tiredness. Other than that, I didn’t notice other side effects.
