Migraine is a type of headache that causes moderate to severe pain. The pain is pulsing or throbbing. It often occurs on one side of your head. Some studies believe that migraine has a genetic cause. Some factors can trigger this kind of condition. These may vary from person to person and they include:

• Hormonal changes in women
• Stress
• Anxiety
• Loud noises
• Bright or flashing lights
• Medicines
• String smells
• Sudden changes in the weather or environment
• Too much or not enough sleep
• Caffeine or caffeine withdrawal
• Skipped meals

For some, they have found that certain foods or ingredients can trigger headaches. It may include:

• Chocolate
• Alcohol
• Some fruits and nuts
• Yeast
• Fermented or pickled goods 

Migraine is a powerful headache that can last from 4 hours to 3 days and sometimes longer. This starts when overactive nerve cells send out signals that activate the trigeminal nerve. It is the nerve that supplies sensation to your head and face. The activation of the nerve may cause the release of certain chemicals called CGRP. CGRP is a calcitonin gene-related peptide that causes blood vessels in the lining of the brain to swell. This releases neurotransmitters that create inflammation and pain. Some signs and symptoms of this condition may include:

• Inability to perform regular activities due to pain
• Increasing pain during physical activity or when straining
• Increased sensitivity to sound and light, only relieved by lying quietly in a darkened room
• Moderate to severe pain usually confined to one side of the head but capable of occurring on either side of the head 
• Feeling sick and physically vomiting 

How does this medication work?

Rizatriptan Benzoate stimulates receptors called serotonin or 5HT receptors. These receptors are found in the brain. A natural substance called serotonin usually acts on these receptors. Wherein, it causes blood vessels in the brain to narrow. Rizatriptan Benzoate imitates the action of serotonin. It is by directly stimulating the serotonin receptors that are in the brain. This narrows the blood vessels and therefore relieves the pain of migraines.
