Doxycycline: Effective Treatment for STIs and Infections
What is Doxycycline?
Doxycycline is a prescription antibiotic that effectively treats sexually transmitted infections (STIs) such as chlamydia, non-specific urethritis, and ureaplasma urealyticum. It can also be used in combination with other medications to treat mycoplasma genitalium.
Additionally, Doxycycline prevents malaria in individuals travelling to high-risk areas. It is available in 100mg capsules and works by stopping the spread of infection, enabling the body to recover.
How Does Doxycycline Work?
Doxycycline belongs to the tetracycline class of antibiotics. It works by inhibiting bacterial growth and preventing bacteria from producing the proteins needed to multiply. This helps your immune system eliminate the infection.
By disrupting bacterial cell function, Doxycycline effectively treats infections and prevents reinfection when taken as prescribed.
