If you miss a dose of this medication, take the missed dose as soon as possible, unless it is almost time for the next dose. In that case, do not take the missed dose at all; just return to your regular dosing schedule. Do not double the next dose. SIDE EFFECTS Minor. None, at the dosages normally prescribed. Major.
