Rizatriptan (Generic Maxalt) - Uses, Side Effects, and More

Everything you need to know about Rizatriptan

How does Rizatriptan work?

In many people living with migraine, there is a problem with certain nerves supplying the blood vessels inside the brain. Either pain is transmitted along these nerves, or the nerves release pain causing chemicals, causing migraine headache symptoms.

Rizatriptan acts like Serotonin, which is a chemical messenger used to send signals between nerves in many different parts of the body. Serotonin has many different effects on the body, however you are probably most familiar with its role as the “happy hormone.” How serotonin is involved in migraines is complex; research has shown that serotonin acts directly on blood vessels in the brain, upon nerves that control how pain is sensed and via a broad network of nerves projecting from the base of the brain (the brainstem) into almost all areas of the brain. (You may see Rizatriptan referred to as a Serotonin (5-HT1) agonist.)

Rizatriptan has 3 different modes of action:

Activation of specific nerves that use Serotonin.
Prevents the release of pain-causing chemicals.
Adjusts the circulation of blood in the brain.

The combination of these mechanisms can reduce the level of pain that a patient experiences. This in turn helps to relieve migraine symptoms once a migraine starts to appear.

How should I take Rizatriptan?

Rizatriptan works immediately to relieve symptoms of migraine headache; we advise taking the tablet as soon as symptoms of migraine first appear. You can take a dose at day or at night, as it does not have caffeine-like or dizziness inducing properties.

Rizatriptan is available as 5 mg and 10 mg tablets. A normal starting dose is 10 mg once daily as required.

If taking an Rizatriptan tablet gives temporary relief of symptoms, but migraine symptoms return after two hours or longer, it may be beneficial to take a second tablet. However if Rizatriptan had no benefit initially in relieving symptoms, taking a second tablet is unlikely to be of any further benefit. This does not mean that the medication will never work for you, and there may be symptom relief in future.

It does not prevent migraine attacks in the future, or make future migraine symptoms less severe. If you find that you are taking this medication for more than 10 days a month you might benefit from preventative treatment. Prolonged use of immediate relief medication used to treat headaches can lead to Medication Overuse Headache.

Please read the prescription instructions provided and follow them closely. Do not take more than two tablets (of 10 mg each) in a 24 hour period.

What do I need to tell my doctor before taking Rizatriptan?

You must tell the clinical team if you have a history or suspected diagnosis of any of the following contraindications. (A contraindication means any condition where you must NOT take Rizatriptan):

Hypersensitivity (allergy) to Rizatriptan or any ingredients in its formulation.
Coronary artery disease/ coronary heart disease including a family history of angina or heart attack.
Suspected or diagnosed coronary artery disease/ coronary heart disease; we may need further information or investigation risk factors such as:
High blood pressure.
High cholesterol levels.
Smoker.
Obesity.
Diabetes.
Menopause.
Male over 40 years of age.
Uncontrolled or severe high blood pressure.
History of stroke or Transient Ischemic Attack.
Ongoing treatment, or treatment in the last 24 hours with medication containing ergot or ergotamine (eg methysergide, dihydroergotamine) or other triptan medication.
Recent treatment in the last two weeks with any Monoamine Oxidase Inhibitor medication (these include antidepressant or antianxiety medications such as Iproniazid, Isocarboxazid, Hydracarbazine, Phenelzine, Tranylcypromine, Bifemelane, Moclobemide, and Pirlindole; anti-Parkinson medications such as Rasagiline, Selegiline, and Safinamide, and the antibiotic Linezolid).

Please notify the clinical team if you have any history of moderate or severe kidney or liver disease. There were no specific concerns in healthy volunteers over the age of 65.

There is limited data on any possible effects to mother or child during pregnancy, breastfeeding, whilst trying to conceive or during fertility treatment. We advise considering alternative options for initial migraine medication in these circumstances.

Prolonged use of immediate or acute migraine medication used to treat headaches can lead to Medication Overuse Headache, especially if you use this medication for more than 10 days in a month. We suggest seeking medical advice if you are concerned by any significant increase in duration, frequency or severity of your symptoms.
