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 your migraine attack. Do not use it to prevent an attack.
Treatment with Rizatriptan reduces swelling of blood vessels surrounding the brain. This swelling results in the headache pain of a migraine attack.

• have or have ever had heart problems including heart attack or pain on the chest
• (angina) or you have experienced heart disease related signs
• have severe liver or severe kidney problems
• have had a stroke (cerebrovascular accident CVA) or mini stroke (transient ischaemic attack TIA)
• have blockage problems with your arteries (peripheral vascular disease)
• 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
• are now taking ergotamine-type medicines, such as ergotamine or dihydro-ergotamine to treat your migraine or methysergide to prevent a migraine attack
• 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)

Rizatriptan.

Other medicines and Rizatriptan
Please tell your doctor if you are taking or have recently taken or plan to 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.

• methysergide to prevent a migraine attack.
The above listed medicines when taken with Rizatriptan may increase the risk of side effects.
