What is Zembrace SymTouch (sumatriptan injection)?
Sumatriptan 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.
Sumatriptan is used to treat migraine headaches and cluster headaches in adults. Sumatriptan will only treat a headache that has already begun. It will not prevent headaches or reduce the number of attacks.
Sumatriptan 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.
Sumatriptan may also be used for purposes not listed in this medication guide.
What should I discuss with my health care provider before using Zembrace SymTouch (sumatriptan injection)?
You should not use this medicine if you are allergic to sumatriptan, or if you have:
coronary artery disease, angina (chest pain), blood circulation problems, lack of blood supply to the heart;
a heart disorder called Wolff-Parkinson-White syndrome;
a history of heart disease, heart attack, or stroke, including "mini-stroke";
untreated or or uncontrolled high blood pressure;
severe liver disease;
circulation problems affecting your intestines; or
a headache that seems different from your usual migraine headaches.
Do not use sumatriptan 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.
To make sure sumatriptan is safe for you, tell your doctor if you have:
liver or kidney disease;
epilepsy or other seizure disorder;
high blood pressure, a heart rhythm disorder; or
risk factors for coronary artery disease (such as diabetes, menopause, smoking, being overweight, having high cholesterol, having a family history of coronary artery disease, being older than 40 and a man, or being a woman who has had a hysterectomy).
Sumatriptan can affect your pupils during cataract surgery. Tell your eye surgeon ahead of time that you are using this medicine.
It is not known whether sumatriptan will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medicine. Your name may need to be listed on a sumatriptan pregnancy registry.
Sumatriptan can pass into breast milk and may harm a nursing baby. Do not breast-feed within 12 hours after using a sumatriptan injection. If you use a breast pump during this time, throw out any milk you collect. Do not feed it to your baby.
Sumatriptan injection is not approved for use by anyone younger than 18 years old.
How should I use Zembrace SymTouch (sumatriptan injection)?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended. Overuse of migraine headache medicine can actually make your headaches worse.
Sumatriptan is injected under the skin. You may be shown how to use injections at home. Do not give yourself this medicine if you do not understand how to use the injection and properly dispose of used needles and syringes.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
Use sumatriptan as soon as you notice headache symptoms, or after an attack has already begun.
Your blood pressure will need to be checked often.
Sumatriptan injection comes in a vial (bottle), an auto-injector or prefilled cartridge to be loaded into an auto-injector syringe, or in a needle-free injector device. Each vial, cartridge, or needle-free device is for one use only.
After using an injection: If your headache does not completely go away after the injection, call your doctor before using a second sumatriptan injection. If your headache goes away and then comes back, you may use a second injection if it has been at least one (1) 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.
Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
Store at room temperature away from moisture, heat, and light. Throw away any unused medicine after the expiration date on the label has passed.
What should I avoid while using Zembrace SymTouch (sumatriptan injection)?
Do not use sumatriptan within 24 hours before or after using another migraine headache medicine, including:
sumatriptan tablets or nasal spray, almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, zolmitriptan; or
ergot medicine such as dihydroergotamine, ergotamine, ergonovine, or methylergonovine.
Sumatriptan may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
For Healthcare Professionals
Applies to sumatriptan: nasal capsule, nasal spray, oral tablet, subcutaneous kit, subcutaneous solution, transdermal film extended release
The more commonly observed adverse reactions have included those of pressure sensation, flushing, tingling, dizziness/vertigo, warm/hot sensation, burning sensation, flushing, and numbness; formulation specific events including injection site reactions, application site pain, and nasal discomfort have been reported.[Ref]
Life-threatening disturbances of cardiac rhythm, such as ventricular tachycardia and ventricular fibrillation leading to death, and rare reports of acute myocardial infarction, have been reported within a few hours after administration of 5-HT1 agonists.
Chest discomfort is usually noncardiac in origin. A survey of 453 migraine patients found chest symptoms occurred in up to 58% of patients in at least some attacks and in up to 42% of patients in all attacks.
One study of 735 consecutive migraine patients reported that chest symptoms are frequent, but rarely important adverse effects of (primarily subcutaneous) sumatriptan (the active ingredient contained in Zembrace SymTouch) The risk of chest symptoms was reported to be patient dependent and not related, even opposite, to cardiovascular disease. This report contradicts the hypothesis that chest symptoms after sumatriptan are caused by cardiac ischemia.
Another study of 125 patients concluded that panic-like symptoms may explain the chest pain and related side effects after sumatriptan administration in patients with high levels of anxiety.[Ref]
Common (1% to 10%): Chest pain/tightness/pressure and/or heaviness, flushing, neck/throat/jaw pain/tightness/pressure, transient increases in blood pressure (arising soon after treatment)
Uncommon (0.1% to 1%): Bradycardia, hypertension, hypotension, palpitations, pulsating sensations, tachycardia, various transient ECG changes (nonspecific ST or T-wave changes, prolongation of PR or QTc intervals, sinus arrhythmia, nonsustained ventricular premature beats, isolated junctional ectopic beats, atrial ectopic beats, delayed activation of the right ventricle)
Rare (less than 0.1%): Abnormal pulse, arrhythmia, pallor, Raynaud's phenomenon, vasodilation
Frequency not reported: Abdominal aortic aneurysm, angina, atherosclerosis, cerebrovascular lesion, coronary artery vasospasm, edema, heart block, peripheral cyanosis, phlebitis, thrombosis, transient myocardial ischemia
Postmarketing reports: Cyanosis, hypotension, myocardial infarction, palpitations[Ref]
Very common (10% or more): Dizziness (10%), abnormal taste (20%; nasal powder)
Common (1% to 10%): Bad/unusual taste, drowsiness/sedation, dystonia, headache, hypoesthesia, paraesthesia (all types), tremor
Uncommon (0.1% to 1%): Syncope

Postmarketing reports: Central nervous system vasculitis, cerebellar infarction, cerebrovascular accident, subarachnoid hemorrhage, serotonin syndrome, temporal arteritis[Ref]
Cerebral hemorrhage, subarachnoid hemorrhage, and stroke have occurred with 5-HT1 treatment; some have resulted in fatalities. One case of sumatriptan-induced cortical stroke has been reported in a patient with sagittal sinus thrombosis. In some cases, it appears possible that the cerebrovascular events were primary, and the 5-HT1 agonist administered in the belief that presenting symptoms were due to migraine when they were not. Patients with migraine may also be at an increased risk of certain cerebrovascular events such as stroke, hemorrhage, and transient ischemic attacks.
Medication overuse headache may present as migraine-like headaches or as a marked increase in frequency of migraine attacks.
Serotonin syndrome is characterized by mental status changes (e.g., agitation, hallucinations, coma), autonomic instability (e.g., tachycardia, labile blood pressure, hyperthermia), neuromuscular aberrations (e.g., hyperreflexia, incoordination), and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). The onset of symptoms generally occurs within minutes to hours of receiving a new or a greater dose of a serotoninergic medications.
Seizures have been reported in patients with either a history of seizures or concurrent conditions predisposing to seizures and also in patients where no such predisposing factors are apparent.[Ref]
Common (1% to 10%): Abdominal discomfort, dysphagia, nausea and/or vomiting
