Can I take Calcium and Doxycycline together?

Varför detta händer

This is an absorption issue called 'chelation'. Calcium binds to the doxycycline molecules in the digestive tract to form a large complex that the body cannot absorb.

You should separate the doses of these two substances. Take your doxycycline at least 2 hours before or 3 hours after consuming calcium-rich foods (like milk, cheese, or yoghurt) or calcium supplements.

Photosensitivity

Doxycycline makes your skin much more sensitive to sunlight. You will burn more easily; avoid sunbeds and use high-factor sunscreen even on cloudy days.

Oesophageal irritation

To prevent painful throat irritation or ulcers, swallow doxycycline with a full glass of water while sitting or standing. Do not lie down for at least 30 minutes after taking it.

Alkohol

Chronic or heavy drinking can speed up the removal of doxycycline from your body, making the antibiotic less effective. It is best to avoid or limit alcohol during your treatment.

Caffeine (coffee, tea, cola)

High amounts of caffeine can slightly interfere with how your body absorbs calcium and may increase the amount of calcium lost in your urine. Try to limit caffeine intake or have it at a different time than your supplement.

High-fibre foods (bran, whole grains) and Spinach/Rhubarb

Foods very high in phytic acid (grains) or oxalic acid (spinach, rhubarb) can bind to calcium and reduce its absorption. Avoid taking your calcium supplement at the same time as a very high-fibre meal.
