Doxycycline hyclate works by slowing bacterial growth and thereby allowing the body's immune system to fight the infection. In common with all antibiotics, doxycycline hyclate does not treat viral infections, notes Drugs.com. Patients take doxycycline hyclate orally on an empty stomach. For malaria prevention, a patient should take the medication daily, starting one or two days before travel to the affected area and continuing for four weeks after leaving the area.

Common side effects include nausea, vomiting, loss of appetite and sensitivity to sunlight, explains Drugs.com. Individuals should seek medical attention immediately if any severe side effects occur, including severe allergic reactions producing a rash, hives, itching, difficulty breathing, tightness in the chest, or swelling of the mouth, face, lips, or tongue. Those experiencing bloody stools, chest pain, dark urine, decreased urination and fever should also seek medical attention. Additional serious side effects include moderate to severe sunburn; red, swollen, blistered, or peeling skin; severe diarrhea; severe or persistent headache; stomach pain or cramps; and throat irritation. Trouble swallowing, unusual bruising or bleeding, unusual joint pain or tiredness, vaginal irritation or discharge, vision changes, and yellowing of the skin or eyes are possible as well.

Some of the brand names of doxycycline include Doryx, Monodox and Oracea, notes MedlinePlus. Other brands of doxycycline are Periostat and Vibramycin, as well as the generic versions of Doxychel and Vibra-Tabs.
