Question 1

What is Rizatriptan?

Question 3

How does Rizatriptan work?

Accepted Answer

Mechanism of Action

Rizatriptan belongs to a class of drugs called selective serotonin receptor agonists. It works by binding to specific receptors in the brain and on the blood vessels. During a migraine attack, blood vessels in the brain can become swollen or dilated. Rizatriptan helps to narrow these blood vessels, which can alleviate the throbbing pain associated with the headache.

In addition to its effect on blood vessels, rizatriptan also helps by:

Reducing the release of certain natural substances that cause inflammation and pain.

Blocking pain signals from being sent to the brain through the trigeminal nerve system.

By targeting these pathways, the medication helps relieve the headache and other common migraine symptoms, such as nausea and sensitivity to light or sound. It is important to note that rizatriptan is designed to treat a migraine attack that has already started; it does not prevent future migraines or reduce how often you experience them.

Question 8

What is the dosage of Rizatriptan and how do I take it?

Accepted Answer

Rizatriptan should be taken as soon as you feel a migraine headache starting. It is not intended to prevent headaches or to treat other types of headaches, such as tension headaches. You may take this medication with or without food, though taking it with food may slightly delay how quickly it starts to work.

Standard Tablets

Swallow the tablet whole with a glass of water or other liquid.

Orally Disintegrating Tablets

If you are using the orally disintegrating form of this medication, follow these steps:

Keep the tablet in its original blister pack until you are ready to take it.

Ensure your hands are dry before opening the blister.

Peel back the foil packaging rather than pushing the tablet through the foil.

Place the tablet on your tongue, where it will dissolve quickly.

Swallow the dissolved tablet with your saliva. You do not need to drink water to take this form of the medication.

Repeat Dosing

If your headache goes away but then returns, you may be able to take an additional dose after a specific amount of time has passed, as directed by your healthcare provider. However, if the initial dose does not help your headache at all, do not take another dose for the same migraine attack without talking to your doctor first. Do not use this medication to treat more than a specific number of headaches each month.

Missed Dose

Because rizatriptan is used only when needed for a migraine attack, it does not have a regular dosing schedule. Do not take more than the maximum amount recommended by your doctor within a single day.

Question 9

Is Rizatriptan safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

There are no adequate and well-controlled studies on the use of rizatriptan in pregnant women. In animal studies, high doses of the medication were associated with developmental issues, but it is unclear how these findings apply to humans. Rizatriptan should be used during pregnancy only if the potential benefit to the patient outweighs the potential risk to the fetus.

Breastfeeding

It is not known whether rizatriptan passes into human breast milk. Because animal studies have shown the drug is present in the milk of lactating rats, healthcare providers advise caution. If you are breastfeeding, consult your doctor to discuss the potential risks and benefits of using this medication.

The orally disintegrating tablets are often packaged in individual blister units to protect the medication from moisture before use.

Question 12

What should I know about Rizatriptan and withdrawal?

Accepted Answer

Medication Overuse Headache

Using rizatriptan for 10 or more days per month can lead to a condition known as medication overuse headache. This occurs when the frequent use of acute migraine medications causes headaches to become more frequent or severe rather than providing relief. This is often referred to as a rebound effect.

Withdrawal Symptoms

If you have developed medication overuse headache, your healthcare provider may advise you to stop taking rizatriptan. Discontinuing the medication after frequent, long-term use can lead to withdrawal-like symptoms, which most commonly include:

A temporary increase in the frequency of headaches.

A temporary increase in the intensity of migraine symptoms.

Management and Prevention

To manage withdrawal and prevent future overuse, healthcare providers may recommend the following steps:

Discontinuing the overused medication under medical supervision.

Treating the withdrawal symptoms as they occur.

Starting a preventive migraine treatment plan to reduce the need for acute medications like rizatriptan.

It is important to follow your doctor's instructions regarding how often you can safely use rizatriptan to avoid these complications.
