Doxycycline 100mg

Doxycycline 100 mg is a broad-spectrum antibiotic from the tetracycline class. It is widely used to treat a variety of bacterial infections, including respiratory, urinary, and sexually transmitted infections. It also plays a role in malaria prevention and acne treatment.

• Respiratory tract infections (pneumonia, bronchitis)

• Urinary tract infections (UTIs)

• Sexually transmitted infections (chlamydia, gonorrhea, syphilis)

• Skin conditions (acne, rosacea)

• Eye infections

• Malaria prevention and treatment

• Rickettsial infections (e.g., Rocky Mountain spotted fever)

• Lyme disease

Doxycycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit. This action prevents bacteria from growing and multiplying, allowing the immune system to eliminate the infection.

• Typical dose: 100 mg once or twice daily depending on the condition
