Avoid taking doxycycline with antacids containing aluminum, calcium, or magnesium. These can reduce doxycycline absorption, diminishing its effectiveness. Space out your doxycycline and antacid doses by at least two to three hours.
Dairy products and iron supplements can also interfere with doxycycline absorption. Take your medication at least two hours before or after consuming these items.
Doxycycline can increase your sun sensitivity. Use sunscreen with an SPF of 30 or higher and wear protective clothing when spending time outdoors, especially during peak sun hours.
Inform your doctor if you’re taking blood thinners like warfarin, as doxycycline may influence their effects. Regular blood tests may be necessary to monitor your INR.
Be aware that doxycycline can interact with certain medications used to treat epilepsy, such as phenytoin. Your doctor might adjust your dosage of either medication if necessary.
Doxycycline can affect the effectiveness of oral contraceptives. Consider using a backup method of contraception while taking this antibiotic.
If you experience any unusual side effects, such as severe stomach pain, unusual bruising or bleeding, or signs of an allergic reaction like swelling or difficulty breathing, contact your doctor immediately.
