Synthroid interacts with several medications, including calcium supplements, iron supplements, antacids, cholesterol-lowering medications (such as cholestyramine and colestipol), certain stomach acid reducers (like omeprazole and lansoprazole), and other thyroid medications. Be sure to tell your healthcare provider about all medications and supplements you are taking before you buy Synthroid online, as drug interactions may affect how it works. This is not a complete list of interactions, so always consult your doctor or pharmacist for more information.
