Dynacin Dosage

Take each dose with a full glass (8 ounces) of water.
You may take this medication with or without food. Do not take the medication with milk or other dairy products, unless your doctor has told you to. Dairy products can make it harder for your body to absorb the medicine. Certain brands of minocycline may not have restrictions about taking them with dairy products.

Take this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Minocycline will not treat a viral infection such as the common cold or flu. Do not give this medicine to another person, even if they have the same condition you have.
If you need to have any type of surgery, tell the surgeon ahead of time that you are taking demeclocycline. You may need to stop using the medicine for a short time.
