Doxycycline is used to slow down the growth of bacteria and treat different kinds of infection. When combined with certain other drugs, doxycycline is efficient for the treatment of amoeba infections. Do not stop taking this medicine even if you feel well after a few days. You need to take the entire amount prescribed to make sure the infection has been properly treated and a relapse is not likely to occur. The most common side effects of doxycycline that you do not have to report to your doctor include nausea and vomiting, sunlight sensitivity and loss of appetite. You should report these symptoms only if they persist, change in intensity or become bothersome interfering with your everyday life.
Some serious effects may sometimes occur in patients taking this medicine, including chest pain, bloody stools, sore throat, fever and chills, persistent headache, severe diarrhea, throat irritation, stomach cramps, easy bleeding and bruising, jaundice, trouble swallowing, vaginal discharge and vision changes. Do not share doxycycline with people to whom it has not been prescribed as this can cause dangerous symptoms in them.
