What is Doxycycline?

  • It's commonly prescribed for respiratory infections, urinary tract infections, skin infections, and certain sexually transmitted infections.

  • Doxycycline belongs to the tetracycline antibiotic class.

How Does it Work and Why is it Important to Take?

  • Doxycycline works by halting the growth of bacteria, preventing them from multiplying.

The Dose of The Medication

How and When to Take It

What to Expect

  • You'll typically feel better within a few days for the majority of infections.
