Warnings

• Do not use doxycycline if you are allergic to it or other tetracycline antibiotics (e.g., tetracycline, minocycline).

Before Using This Product

How Should I Take Doxycycline (Vibramycin)?

• With Food: Take doxycycline with a full glass of water. It can be taken with food or milk to reduce stomach upset, but dairy products may decrease absorption.
• Duration: Complete the entire course of treatment, even if symptoms improve, to prevent antibiotic resistance.

What Happens If I Miss a Dose?

• If it is almost time for the next dose, skip the missed dose and continue with your regular schedule.
• Do not double doses to make up for a missed dose.

• Avoid prolonged sun exposure, and use sunscreen or protective clothing to prevent photosensitivity reactions.
