1. what rizatriptan is and what it is used for

Rizatriptan belongs to a class of medicines called selective serotonin 5-HTib/id receptor agonists.

Your doctor has prescribed Rizatriptan to treat the headache phase of the migraine attack in adults.

Treatment with Rizatriptan reduces swelling of blood vessels surrounding the brain. This swelling results in the headache pain of a migraine attack.

2. what you need to know before you take rizatriptan

Do not take Rizatriptan if:

  • you are allergic to rizatriptan or any of the other ingredients of this medicine (listed in section 6)
  • you have moderately severe or severe high blood pressure or mild high blood pressure that is not controlled by medicines
  • you have or have ever had heart problems including heart attack or pain on the chest (angina) or you have experienced heart disease-related signs
  • you have severe liver or severe kidney problems
  • you have had a stroke (cerebrovascular accident-CVA) or mini stroke (transient ischaemic attack-TIA)
  • you have blockage problems with your arteries (peripheral vascular disease)
  • you are taking monoamine oxidase (MAO) inhibitors such as moclobemide, phenelzine, tranylcypromine or pargyline (medicines against depression) or linezolid (an antibiotic) or if it has been less than two weeks since you stopped taking MAO inhibitors
  • you are now taking ergotamine-type medicines, such as ergotamine or dihydro-ergotamine to treat your migraine or methysergide to prevent a migraine attack
  • you are taking any other medicine in the same class, such as sumatriptan, naratriptan or zolmitriptan to treat your migraine (see Other medicines and Rizatriptan below).

If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before taking Rizatriptan.

Warnings and precautions

  • Talk to your doctor or pharmacist before taking Rizatriptan, if: you have any of the following risk factors for heart disease: high blood pressure, diabetes, you smoke or you are using nicotine substitution, your family has a history of heart disease, you are a man over 40 years of age, or you are a post-menopausal woman
  • you have kidney or liver problems
  • you have a particular problem with the way your heart beats (bundle branch block)
  • you have or have had any allergies.
  • your headache is associated with dizziness, difficulty in walking, lack of coordination or weakness in the leg and arm
  • you use any herbal preparation containing St. John’s wort
  • you have had an allergic reaction like swelling of the face, lips, tongue and/or throat which may cause difficulty breathing and/or swallowing (angioedema).
  • you are taking selective serotonin reuptake inhibitors (SSRIs) such as sertraline, escitalopram oxalate, and fluoxetine or serotonin norepinephrine reuptake inhibitors (SNRIs) such as venlafaxine and duloxetine for depression.
  • you have had short lived symptoms including chest pain and tightness.

If you take Rizatriptan too often, this may result in you getting a chronic headache. In such cases you should contact your doctor as you may have to stop taking Rizatriptan.

Tell your doctor or pharmacist about your symptoms. Your doctor will decide if you have a migraine. You should take Rizatriptan only for a migraine attack. Rizatriptan should not be used to treat headaches that might be caused by other, more serious conditions.

Other medicines and Rizatriptan

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription. This includes herbal medicines and those you normally take for a migraine. This is because Rizatriptan can affect the way some medicines work. Also, other medicines can affect Rizatriptan.

Do not take Rizatriptan if you are taking:

  • a 5-HTib/id agonist (sometimes referred to as ‘triptans’), such as sumatriptan, naratriptan or zolmitriptan
  • a monoamine oxidase (MAO) inhibitor such as moclobemide, phenelzine, tranylcypromine, linezolid or pargyline or if it has been less than two weeks since you stopped taking an MAO inhibitor
  • ergotamine-type medicines such as ergotamine or dihydro-ergotamine to treat your migraine
  • methysergide to prevent a migraine attack.

The above listed medicines when taken with Rizatriptan may increase the risk of side effects.

You should wait at least 6 hours after taking Rizatriptan before you take ergotamine- type medicines such as ergotamine or dihydro-ergotamine or methysergide.

You should wait at least 24 hours after taking ergotamine-type medicines before taking Rizatriptan.

Ask your doctor for instructions and the risks about taking Rizatriptan if you are taking:

  • propranolol (see section 3)
  • SSRIs such as sertraline, escitalopram oxalate and fluoxetine or
  • SNRIs such as venlafaxine and duloxetine for depression.

Rizatriptan with food and drink

Rizatriptan can take longer to work if it is taken after food. Although it is better to take it on an empty stomach, you can still take it if you have eaten.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby ask your doctor or pharmacist for advice before taking this medicine.

It is not known whether Rizatriptan is harmful to an unborn baby when taken by a pregnant woman.

Breast-feeding should be avoided for 24 hours after treatment.

Driving and using machines

You may feel sleepy or dizzy while taking Rizatriptan. If this happens, do not drive or use any tools or machines.

This medicine contains 2.90mg aspartame in each orodispersible tablet.

3. how to take rizatriptan

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

The recommended dose is 10mg.

If you are currently taking propranolol or have kidney or liver problems you should use the 5mg dose of Rizatriptan. You should leave at least 2 hours between taking propranolol and Rizatriptan up to a maximum of 2 doses in a 24-hour period.

Take Rizatriptan as soon as possible after your migraine has started. Do not use it to prevent an attack.

If migraine returns within 24 hours

In some patients, migraine symptoms can return within a 24-hour period. If your migraine does return, you can take an additional dose of Rizatriptan. You should always wait at least 2 hours between doses.

If after 2 hours you still have migraine

If you do not respond to the first dose of Rizatriptan during an attack, you should not take a second dose of Rizatriptan for treatment of the same attack. It is still likely, however, that you will respond to Rizatriptan during the next attack.
