What is sumatriptan? What are the uses for sumatriptan?
Sumatriptan is a drug that is used for treating migraine headaches. It belongs to a class of drugs called selective serotonin receptor agonists. Other members of this class include naratriptan (Amerge), zolmitriptan (Zomig), rizatriptan (Maxalt), frovatriptan (Frova), eletriptan (Relpax), and almotriptan (Axert).
Migraine headaches are believed to result from dilatation of blood vessels in the brain. Sumatriptan relieves migraines by stimulating serotonin receptors in the brain which cause the muscles surrounding the blood vessels in the brain to contract and narrow the blood vessels. At the same time, it also reduces transmission of pain signals by nerves to the brain. While it is very effective in relieving migraine headaches, it does not prevent or reduce the number of headaches. The FDA approved sumatriptan in December 1992.
What brand names are available for sumatriptan?

What are the side effects of sumatriptan?
Side effects are generally transient. Some common side effects of sumatriptan:
- pain or tightness in the chest or throat,
- abdominal discomfort,
- nasal irritation, and
- injection site reactions.
Rarely, allergic reactions have been reported, usually in individuals who are highly allergic to multiple allergens. Sumatriptan may elevate blood pressure in individuals with or without a history of high blood pressure. Individuals with uncontrolled high blood pressure should not use sumatriptan.
Other important, but rare, side effects associated with sumatriptan include:
What is the dosage for sumatriptan?
- The recommended oral dose is 25-100 mg and the maximum dose is 200 mg daily.
- The recommended intranasal dose is 5-20 mg and the maximum dose is 40 mg daily.
- The recommended injection dose is 4 or 6 mg injected under the skin.
- The maximum dose is two 6 mg injections separated by 1 hour.
- The recommended dose for the Zecuity patch is one patch applied to dry intact, non-irritated skin on the upper arm or thigh on a site that is relatively hair free and is without scars, tattoos, abrasions, or other skin conditions.
Which drugs or supplements interact with sumatriptan?
Monoamine oxidase inhibitors or MAOIs, for example, isocarboxazid (Marplan), phenelzine (Nardil), tranylcypromine (Parnate), and procarbazine (Matulane), may reduce the breakdown of sumatriptan in the liver, leading to increased blood levels and side effects of sumatriptan.
Combining sumatriptan with sibutramine (Meridia), selective serotonin reuptake inhibitors or SSRIs, including fluoxetine (Prozac), citalopram (Celexa), paroxetine (Paxil), and sertraline (Zoloft) or serotonin and norepinephrine reuptake inhibitors, including venlafaxine (Effexor), duloxetine (Cymbalta), and desvenlafaxine (Pristiq) may increase the concentration of serotonin in the brain, causing increased serotonin-related side effects.
Administering sumatriptan within 24 hours of treatment with an ergot-containing medication (dihydroergotamine [Migranal], ergotamine [Methergine]) is contraindicated because such combinations increase the likelihood of vasospasms.
Is sumatriptan safe to take if I'm pregnant or breastfeeding?
Safe use in pregnancy has not been established.
Sumatriptan is excreted in breast milk. Infant exposure may be reduced by avoiding breast feeding for 12 hours after administration of sumatriptan.

Irritable Bowel Syndrome (IBS)
Irritable bowel syndrome (IBS) is a GI (gastrointestinal) disorder with signs and symptoms that include abdominal pain, bloating, increased gas (flatulence), abdominal cramping, diarrhea, constipation, and food intolerance.Two new tests are now available that may help diagnose irritable bowel syndrome with diarrhea and constipation (IBS-M) irritable bowel syndrome with diarrhea (IBS-D), and irritable bowel syndrome with constipation (IBS-C). Treatment for IBS includes diet changes, medications, and other lifestyle changes to manage symptoms.
Migraine headache is a type of headache associated with a sensitivity to light, smells, or sounds, eye pain, severe pounding on one side of the head, and sometimes nausea and vomiting. The exact cause of migraine headaches is not known. Triggers for migraine headaches include certain foods, stress, hormonal changes, strong stimuli (loud noises), and oversleeping. Treatment guidelines for migraines include medicine, pain management, diet changes, avoiding foods that trigger migraines, staying hydrated, getting adequate sleep, and exercising regularly. Prevention of migraine triggers include getting regular exercise, drinking water daily, reducing stress, and avoiding trigger foods.
Vertigo is the sensation of spinning or rocking, even when someone is at rest. Vertigo may be caused by a problem in the brain or spinal cord or a problem within in the inner ear. Head injuries, certain medications, and female gender are associated with a higher risk of vertigo. Medical history, a physical exam, and sometimes an MRI or CT scan are required to diagnose vertigo. The treatment of vertigo may include medication, special exercises to reposition loose crystals in the inner ear, or exercises designed to help the patient re-establish a sense of equilibrium. Controlling risk factors for stroke (blood pressure, weight, cholesterol, and blood glucose) may decrease the risk of developing vertigo.
Chronic pain is pain (an unpleasant sense of discomfort) that persists or progresses over a long period of time. In contrast to acute pain that arises suddenly in response to a specific injury and is usually treatable, chronic pain persists over time and is often resistant to medical treatments.
Headaches can be divided into two categories: primary headaches and secondary headaches. Migraine headaches, tension headaches, and cluster headaches are considered primary headaches. Secondary headaches are caused by disease. Headache symptoms vary with the headache type. Over-the-counter pain relievers provide short-term relief for most headaches.
Cluster headaches are a type of headache that recurs over a period. Episodes can last one to three times a day during this time, which may last from 2 weeks to 3 months. The three main types of treatments for cluster headaches are, 1) Abortive medications that work to stop the process in the brain that causes migraines and stops the symptoms too. 2) Preventive prescription medications, or 3) surgery which involves blocking the trigeminal nerve.
Pain management and treatment can be simple or complex, according to its cause. There are two basic types of pain, nociceptive pain and neuropathic pain. Some causes of neuropathic pain include: complex regional pain syndrome, interstitial cystitis, and irritable bowel syndrome. There are a variety of methods to treat chronic pain, which are dependant on the type of pain experienced.
Abdominal Migraines in Children and Adults
Abdominal migraine in adults and children is a variant of migraine headaches. Abdominal migraine in children generally occurs in children who have a family history of migraines. Causes of abdominal migraine is not known. Symptoms of abdominal migraine include acute, severe, midline abdominal pain, nausea, vomiting, paleness, and inability to eat. Abdominal migraine is diagnosed through patient history, family history, and ruling out other medical causes. Treatment of abdominal migraine include tricyclic antidepressants and triptans.
Cyclic Vomiting Syndrome (CVS)
Cyclic vomiting syndrome is a condition in which affected individuals have severe nausea and vomiting that come in cycles. Researchers believe that cyclic vomiting syndrome and migraine headaches are related. Triggers of cyclic vomiting syndrome are emotional stress and infections. People with cyclic vomiting syndrome are at an increased risk of dehydration. Cyclic vomiting syndrome is difficult to diagnose. Treatment varies from person to person, but is generally directed toward relief of the symptoms of the condition.
