Do not take your medicine together with dairy products. This is because dairy foods like milk, cheese and yoghurt can stop your body from absorbing doxycycline. You can have dairy products a few hours before or after your dose. It's best not to drink alcohol with doxycycline because it can stop it working properly.
What foods interfere with doxycycline? Both dairy products and iron-rich foods can interfere with doxycycline if taken at the same time. Avoid eating these foods within two hours of your doxycycline dose. Some foods you should avoid taking with doxycycline include milk, butter, cheese, eggs, kale, and spinach.
Because the tetracycline medications are highly acidic to begin with, tell your patients not to take the pills with acidic beverages, such as orange juice, apple juice, coffee, etc.
The reason milk and other dairy products affect the body's absorption of doxycycline is that they contain calcium. Calcium reacts with doxycycline in a process called chelation. This process forms a new compound called chelate, which is harder for your intestines to absorb.
If you're taking a higher dose of 100mg or more for other types of infection, you can take it with or without food. But you're less likely to feel sick if you have it with food.

Doxycycline starts working in as little as 2 hours after taking it. But depending on the infection you have, it may take up to 24 to 48 hours (1 to 2 days) to start seeing its effects. It typically takes 1 to 2 weeks for doxycycline to fully clear an infection, but some infections can take as long as 2 months.
Alcohol should not interact or cause a severe reaction with doxycycline. However, heavy or chronic alcohol use could shorten the effects of doxycycline in the body (Mergenhagen, 2020). While limited alcohol may not cause a severe reaction, it's still not a good idea to mix alcohol and doxycycline.
Doxycycline may also cause nausea and stomach pain. These side effects can often be lessened by taking doxycycline with food.
Doxycycline can cause severe indigestion and problems with your throat and oesophagus if the tablets are not swallowed properly. Remain upright for at least 30 minutes after taking doxycycline. Don't lie down for at least 30 minutes after taking doxycycline and don't take it just before bed.

Doxycycline does not directly cause weight gain. However, because it eliminates all bacteria including gut bacteria that is responsible for weight control and inflammation, it may temporarily increase your weight. However, any added weight gain should go away after you complete your dose of antibiotics.
Doxycycline is bacteriostatic: it inhibits the growth of bacteria but doesn't kill them directly. On the other hand, amoxicillin is bactericidal: it directly kills the bacteria. Both drugs can target Gram-positive and Gram-negative bacteria, which have thick and thin cell walls, respectively.
