Can I take Doxycycline and Milk together?

Why this happens

Doxycycline binds to the calcium found in milk. This creates large, solid clumps in your stomach that are too big for your body to absorb. Instead of entering your blood to fight bacteria, the medicine simply passes through your system.

Avoid consuming milk, dairy products, or calcium supplements for at least 2 hours before or 2 hours after taking your doxycycline dose. If you find the medicine upsets your stomach, you can take it with food, but ensure that food is dairy-free.

Interaction with dairy products

Do not take doxycycline at the same time as milk or dairy products. Calcium binds to the medicine, preventing your body from absorbing it and making the treatment less effective. Space them at least 2 hours apart.

Sun sensitivity (Photosensitivity)

Doxycycline makes your skin much more sensitive to sunlight. You may burn very quickly and severely. Avoid sunbeds and use high-factor sunscreen even on cloudy days.

Oesophageal irritation

This medicine can cause severe irritation or ulcers in the throat. Swallow the capsules whole with a full glass of water while sitting or standing, and do not lie down for at least 30 minutes after taking it.

Dairy products (milk, cheese, yoghurt)

Dairy products can significantly reduce the amount of doxycycline absorbed by your body, making the medicine less effective. Avoid consuming dairy for at least 2 hours before or after taking your dose.

Calcium-fortified drinks and juices

Drinks with added calcium can interfere with how your body absorbs this medicine. Leave a gap of at least 2 hours between these drinks and your medication.

Alcohol

While a small amount of alcohol is generally safe, chronic heavy drinking can make doxycycline leave your body faster, potentially making it less effective at fighting your infection.
