Serc is taken daily as per your doctor’s directions. It is an oral tablet that is taken with water and preferably food as well. You’ll want to take this medication as long as your doctor instructs you to. It may take a while to work and when you do begin to feel relief keep taking it, even if you feel well, to make sure the medicine works properly. If you miss a dose do not take it right away to catch up. Simply wait until it is time for your next dose so you can return to your regular schedule. This is not recommended for children. Serc should not affect your ability to drive but the symptoms of vertigo may impede your ability to drive safely.
