Doxycycline side effects

Doxycycline side effects :
a look at Purpose, Interactions and Warnings

Doxycycline is used to treat bacterial infections, including pneumonia, lyme disease, acne, venereal (sexually transmitted) diseases, and inhalational anthrax (after exposure). It also is used to prevent malaria. Doxycycline is in a class of medications called tetracycline antibiotics. It works by preventing the growth and spread of bacteria. Antibiotics will not work for colds, flu, or other viral infections.

Doxycycline side effects and interactions

If your symptoms do not improve within a few days (or a few weeks or months for acne patients), or if they become worse, check with your doctor.

Oral contraceptives (birth control pills) containing estrogen may not work properly if you take them while you are taking tetracyclines. Unplanned pregnancies may occur. You should use a different or additional means of birth control while you are taking tetracyclines. If you have any questions about this, check with your health care professional.

Before having surgery (including dental surgery) with a general anesthetic, tell the medical doctor or dentist in charge that you are taking a tetracycline. This does not apply to doxycycline, however.

Tetracyclines may cause your skin to be more sensitive to sunlight than it is normally. Exposure to sunlight, even for brief periods of time, may cause a skin rash, itching, redness or other discoloration of the skin, or a severe sunburn. If you have a severe reaction, check with your doctor.

Along with its needed effects, there may be unwanted Doxycycline side effects. Although not all of these Doxycycline side effects may occur, if they do occur they may need medical attention.

If your infants and children have been prescribed Doxycycline, check with your doctor as soon as possible if their teeth become discolored.

Other Doxycycline side effects may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. However, check with your doctor if any of the following side effects continue or are bothersome:

More Commonly Observed

Cramps or burning of the stomach; diarrhea.

Less Commonly Observed

Itching of the rectal or genital (sex organ) areas; sore mouth or tongue.

In some patients tetracyclines may cause the tongue to become darkened or discolored. This effect is only temporary and will go away when you stop taking this medicine.

Other Doxycycline side effects not listed above may also occur in some patients. If you notice any other effects, check with your doctor.
