Imitrex STATdose Pen SubQ

If your symptoms are only partly relieved or your headache returns, 2 hours after the injection you may switch to sumatriptan taken by mouth instead of using a second injection. After the initial injection you may take sumatriptan by mouth every 2 hours if needed to a maximum of 100 milligrams of tablets in a 24-hour period.

If you have never taken this medication before and you have risk factors for heart disease (see Precautions), you may need to be monitored for rare but serious side effects (e.g., chest pain) when you take the first dose. Your doctor may ask you to take the first dose in the office.

Your dosage is based on your medical condition and response to therapy. Tell your doctor if your condition does not improve or worsens.
