What is Alsuma?

Alsuma is a headache medicine that narrows blood vessels around the brain. Sumatriptan also reduces substances in the body that can trigger headache pain, nausea, sensitivity to light and sound, and other migraine symptoms.

Alsuma auto-injector is used to treat migraine headaches and cluster headaches in adults. Alsuma will only treat a headache that has already begun. It will not prevent headaches or reduce the number of attacks.

Alsuma should not be used to treat a common tension headache or a headache that causes loss of movement on one side of your body. Use this medicine only if your condition has been confirmed by a doctor as migraine headaches.

Warnings

You should not use Alsuma if you have ever had heart disease, coronary artery disease, blood circulation problems, Wolff-Parkinson-White syndrome, uncontrolled high blood pressure, severe liver disease, a heart attack or stroke, or if your headache seems to be different from your usual migraine headaches.

Do not use Alsuma if you have used an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, tranylcypromine, and others.

Do not use Alsuma within 24 hours before or after using another migraine headache medicine..

How should I use Alsuma?

Your doctor may want to give your first dose of this medicine in a hospital or clinic setting to see if you have any serious side effects.

Alsuma is a disposable one time use, pre-filled auto-injector.

After using an injection: If your headache does not completely go away after the injection, call your doctor before using a second Alsuma injection. If your headache goes away and then comes back, you may use a second injection if it has been at least one hour since your first injection. Do not use more than two (2) injections in 24 hours. If your symptoms do not improve, contact your doctor before using any more injections.
