Doxycycline monohydrate 100 mg is a widely used antibiotic that treats many bacterial skin infections by stopping bacteria from growing and spreading. It is commonly prescribed for moderate to severe acne, especially when acne is inflamed, painful, or not responding to topical treatments. Doxycycline helps reduce acne-causing bacteria and inflammation, leading to clearer skin over time.
Doctors also use doxycycline to treat skin and soft tissue infections caused by bacteria such as Staphylococcus aureus, including certain cases of MRSA (methicillin-resistant Staphylococcus aureus). It can be effective for conditions like boils, abscesses, infected hair follicles (folliculitis), and some forms of cellulitis, particularly when the infection is mild to moderate.
In addition, doxycycline is often prescribed for rosacea, where it helps control redness, swelling, and acne-like bumps due to its anti-inflammatory properties. It may also be used for infected insect bites, minor wounds, or skin infections after injury, when bacteria are involved.
Doxycycline does not treat viral or fungal skin infections, and it should always be taken exactly as prescribed. Completing the full course is important to fully clear the infection and prevent antibiotic resistance.
