Why can't you have dairy while you are taking doxycycline hyclate 100 mg?


Official Answer Medically reviewed by Last updated on Sep 23, 2020.

Doxycycline belongs to a class of drugs called tetracyclines. Tetracyclines are broad spectrum antibiotics used to treat infections of the chest, sinus, eyes, pelvic infections and skin conditions such as acne and rosacea.

There is a drug interaction between doxycycline and calcium. Diary products are high in calcium.,2917-13737

General recommendations are doxycycline and calcium should be separated by two to three hours or longer if possible.
This is because calcium binds to (chelates with) doxycycline and reduces it's absorption, perhaps decreasing it's effectiveness.
This also applies to iron preparations and antacids.

Also no sunshine. Take acidiphilis probiotic 3 hours before or after any antibiotic. I take three a day.drink plenty of water!

In addition to calcium containing compounds negatively impacting the somatic absorption of Doxy, please be aware that those taking an extended dose of antibiotics may lose their tolerance of 'dairy' altogether; particularly if you are over the age of 45. Your gut fauna changes due to the Doxy, hence the need for pro-biotics (esp. Saccharomyces Boulardii) to facilitate the displacement of potentially 'bad' gut cultures (esp. C. deficil).
