Rizatriptan is a medication of the triptan class that is used for the treatment of migraine headaches. It works by affecting serotonin, which is a naturally produced chemical that causes the narrowing of the blood vessels in the brain. Keep in mind that Rizatriptan does not stop migraines from occurring. It only helps to lessen the pain of a migraine headache that has already started.
In addition, Rizatriptan also provides relief for other symptoms of migraines, like vomiting, nausea, and sensitivity to sound/light. Rizatriptan should be taken as soon as you start feeling the onset of a migraine headache, this way you are likely to better manage your symptoms and get relief early, thus improving quality of life.
Directions
The dosage you need to take will be determined by your medical condition and your response to the medication. Your doctor will prescribe you the dose you need to start with. If you don't notice any improvement in your condition, it is recommended that you do not take more of this medication before consulting your doctor.
You can take this medication by swallowing it whole with water, with or without food. Take a Rizatriptan tablet as soon as you feel the first signs of an oncoming migraine headache.
If you only get partial relief, or if your headache comes back, then you may be able to take a second dose after 2 hours but ensure you have discussed this with your clinician beforehand. Do not exceed 20 mg in a 24 hour period. If your migraine has not responded to the initial dose then you should not take a second dose for the same attack.
Side Effects
The following is a list of possible side effects of Rizatriptan. Keep in mind that the vast majority of people do not experience most of these side effects:
Raised blood pressure. Regularly check your blood pressure and tell your doctor if you have high blood pressure.
Tightness in the neck/chest/jaw, or pain and pressure in those areas. These are symptoms associated with a heart attack, but they are usually not as serious. Other symptoms of a heart attack that might be caused by Rizatriptan are unusual sweating or shortness of breath. Get immediate medical help if you start having these side effects.
Allergic reactions to Rizatriptan are rare. If you do get an allergic reaction, seek medical attention right away.
Feelings of tingling or numbness, flushing, heat, or feelings of weakness and drowsiness can also occur for some people. If you get these symptoms, and they persist or get worse, contact your doctor without delay.
Rizatriptan works by increasing the serotonin levels in the brain. A rare side effect of this can be a serious condition called 'serotonin syndrome/toxicity’. The risks are further increased if you are taking other medications that increase the serotonin level in the brain. This is why you must tell your doctor about all the medications you are taking before getting a prescription for Rizatriptan.
Warnings
If you have a risk for heart problems, your doctor might want to perform a heart exam on you before you start to take Rizatriptan. You might also be asked to take your first dose in the doctor's office, so that you can have medical supervision in case you get any adverse reaction to the medication.
If you keep taking Rizatriptan for 10 days or more in a row, your headaches can potentially start to get worse. If you feel the need to take it for longer than 10 days in a row, ask your doctor for advice first.

All of these are factors that will need to be taken into account before you can take Rizatriptan.
