Take a missed dose of isoniazid-pyrazinamide-rifampin (Rifater) right away, unless you are almost due for your next dose. In that case, you should skip the dose you missed and return to the normal dosing schedule. Never take a double dose of this drug. Be sure to let your doctor know that you missed a dose.
