It is important to get each dose of this medication as scheduled. If your dose is given weekly and you miss a dose, use it as soon as you remember. Start your new weekly dosing schedule from that day on. If your dose is given every 2 or 4 weeks and you miss a dose, give a dose if it is less than 7 days from the missed dose. If your dose is given every 2 weeks and it is more than 7 days from the missed dose, then skip the missed dose. Use your next dose at the regular time. If your dose is given every 4 weeks and it is more than 7 days from the missed dose, then start a new dosing schedule with the first dose given right away. For any missed doses, do not double the dose to catch up.
