Description
Doxycycline belongs to the class of medications known as tetracyclines. It is an antibiotic that is used to treat certain infections that are caused by bacteria. It is most commonly used to treat lung infections such as pneumonia and bronchitis, urinary tract infections such as cystitis, throat infections such as tonsillitis, skin infections, and sexually transmitted infections.
The dose and length of treatment with doxycycline varies with the condition being treated. The usual recommended adult dose of doxycycline is 200 mg for the first dose followed by 100 mg once daily at the same time each day, with or after a meal. For some types of infections, doxycycline may be given twice daily.
The medication should be taken with plenty of water while standing or sitting upright to reduce the risk of injury to the esophagus. Do not lie down for at least 1 to 2 hours after taking the medication. This medication should not be taken with antacids or iron preparations, as these may interfere with its effectiveness.
