How should I use dihydroergotamine injection (D. H. E. 45)?
Use exactly as prescribed by your doctor. Never use more than your prescribed dose of dihydroergotamine. Tell your doctor if the medicine seems to stop working as well in treating your migraine attacks.
Dihydroergotamine is injected into a muscle. You may be shown how to use injections at home. Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles and syringes.
Use dihydroergotamine injection as soon as you notice headache symptoms, or after an attack has already begun.
If your headache does not completely go away, you may use a second injection after 1 hour has passed, and a third injection if needed after another hour has passed (a total of 3 injections).
If you still have migraine symptoms after using 3 injections, call your doctor before using any more. If your headache goes away and then comes back, you may use the medication again if it has been at least 6 hours since your last injection.
Do not use more than a total of 3 injections of this medication in any 24-hour period. Do not use more than a total of 6 injections over a period of 7 days.
Dihydroergotamine injection should be clear and colorless. Do not use if the liquid has changed colors or has particles in it. Call your doctor for a new prescription.
If you use dihydroergotamine long-term, your doctor may want to check your heart function periodically using an electrocardiograph or ECG (sometimes called an EKG), a machine that measures electrical activity of the heart.
Store at room temperature away from moisture, heat, and light. Do not use if the expiration date on the label has passed.
