Medication Summary

Medication Summary: This section summarizes DailyMed drug label information to make the label easier to understand. It is not a substitute for the official label, pharmacist counseling, prescriber instructions, or medical advice.

Overview

Doxycycline hyclate capsules are an oral antibacterial medicine. The label says doxycycline should be used only for infections that are proven or strongly suspected to be caused by bacteria, and also for certain malaria prevention uses in short-term travelers.

The label lists many possible uses, including certain respiratory, sexually transmitted, rickettsial, and other bacterial infections, as well as severe acne and malaria prophylaxis. For some infections, culture and susceptibility testing are recommended because resistance can occur.

Important label warnings include tooth discoloration in developing teeth, risk of C. difficile-associated diarrhea, severe skin reactions, intracranial hypertension, photosensitivity, and esophageal irritation or ulceration. The label also says this medicine should not be used in people with hypersensitivity to any tetracycline.

Each capsule contains doxycycline hyclate equivalent to doxycycline 50 mg or 100 mg, along with inactive ingredients and capsule/printing components listed on the label.
