Doxycycline belongs to the groups of tetracycline antibiotics and is used to slow down the growth of bacteria in your body, treating such infections as acne, gonorrhea, chlamydia, periodontitis, blemishes, acne-like lesions and bumps. Doxycycline can be also used for other conditions as prescribed by your doctor. Drug interactions can lead to unpredictable and dangerous symptoms. Do not take doxycycline if you are also taking penicillin, isotretinoin, acitretin, barbiturates, hormonal birth control pills, hydantoins, acitretin, anticoagulants, digoxin, methotrexate, methoxyflurane, live oral typhoid vaccine or carbamazepine.
Doxycycline can also affect the accuracy of some lab tests. If you are going to receive dental care or have a scheduled surgery tell your doctor that you are taking doxycycline. You may be required to temporarily stop using this medicine. Doxycycline can harm an unborn baby and it also passes into breast milk. Avoid getting pregnant or breastfeeding throughout the entire period of the treatment. Take doxycycline for the full course of the treatment otherwise the infection may not be completely cleared from your body.
