What is doxycycline?
Doxycycline is a tetracycline antibiotic that inhibits bacterial growth and is thought to have anti-inflammatory effects. Doxycycline is used for bacterial infections, including acne, rosacea, urinary and respiratory tract infections, eye infections, gum disease, gonorrhea, chlamydia, and syphilis. Doxycycline can also be used to prevent malaria and treat infections caused by mites, ticks, or lice.
Doxycycline hyclate and doxycycline monohydrate are two different salt forms of doxycycline available; one difference between the two is that doxycycline hyclate is soluble in water, while doxycycline monohydrate is very slightly soluble in water.
Doxycycline 100mg, 75mg, and 50mg are the most common strengths of capsules and tablets available. It is also available as an injection, suspension, or syrup.
