If you have any of these other conditions, you may need a dose adjustment or special tests to safely take clarithromycin:
FDA pregnancy category C. It is not known whether clarithromycin is harmful to an unborn baby. Before taking this medication, tell your doctor if you are pregnant or plan to become pregnant during treatment.
It is not known whether clarithromycin passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Do not give this medicine to a child younger than 6 months of age.
Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.
Take this medication with a full glass (8 ounces) of water.
Clarithromycin tablets and oral suspension (liquid) can be taken with or without food.
Clarithromycin extended-release tablets (Biaxin XL) should be taken with food
Do not crush, chew, or break an extended-release tablet. Swallow the pill whole. It is specially made to release medicine slowly in the body. Breaking the pill would cause too much of the drug to be released at one time.
Shake the oral suspension well just before you measure a dose. To be sure you get the correct dose, measure the liquid with a marked measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
Take this medication for the entire length of time prescribed by your doctor. Clarithromycin is usually given for 7 to 14 days (or longer when treating stomach ulcer). Your symptoms may get better before the infection is completely treated. Clarithromycin will not treat a viral infection such as the common cold or flu.
Store this medication at room temperature away from moisture and heat. Do not keep the oral liquid in a refrigerator.
