What is rizatriptan?
Rizatriptan is used to ease the symptoms of migraine headaches. It works by releasing a chemical called serotonin, which causes the blood vessels around your brain to contract (narrow). This reverses the dilating (widening) of blood vessels that are believed to be part of the headache process. Rizatriptan belongs to a group of medicines called triptans. Rizatriptan only works when a migraine attack has already begun. It will not prevent a migraine. Do not take it before your headache begins, or during the aura phase, as it may be less effective. Read more about migraine headaches.
In New Zealand rizatriptan is available as tablets (10 mg). The tablet dissolves when you place it on your tongue. It may be useful if you find drinking water difficult during a migraine or you cannot swallow tablets. It is not useful if you are vomiting.
- Take 1 tablet (10 mg) at the start of the migraine attack. Rizatriptan should work within 30 minutes.
- If your migraine improves but then comes back, wait at least 2 hours before taking another tablet (10 mg).
- Do not take more than 3 tablets (30 mg) in 24 hours. If your symptoms have not improved, contact your doctor before taking any more tablets.
- If the first rizatriptan tablet does not relieve your symptoms or help your migraine, do not take another rizatriptan tablet for the same attack. It is unlikely to work.
Do not use rizatriptan for more than 10 days per month. Using rizatriptan too frequently can cause medication overuse headache or rebound headache. This headache is caused by overuse of painkillers to treat headache, including the use of triptans for migraine. The symptoms include a tension-type headache or migraine-like attack. Headaches often improve within 7 to 10 days after rizatriptan has been stopped. Symptoms may be worse before an improvement is seen. To avoid this, do not use rizatriptan for more than 10 days per month.
How to take rizatriptan
- Take rizatriptan as soon as you notice headache symptoms, or after a migraine has already begun.
- Rizatriptan usually starts to work within 30 minutes of taking the tablet.
- Open the packet with dry hands. Place the rizatriptan tablet on your tongue and allow it to dissolve then swallow with saliva. You do not need to drink water to take your rizatriptan tablet. It is only absorbed after swallowing.
- It does not matter if you take rizatriptan with or without food.
Precautions – before taking rizatriptan
If you answer ‘yes’ to any of the following questions, it’s important that you tell your doctor or pharmacist before taking rizatriptan.
- Do you have problems with your liver or kidneys?
- Do you have problems with high blood pressure (hypertension)?
- Have you had a heart attack or do you get angina (chest pain)?
- Have you had a stroke or do you get transient ischemic attacks?
- Are you pregnant?
- Are you breastfeeding?
- Are you taking medication for depression?
Sometimes a medicine isn’t suitable for a person with certain conditions, or it can only be used with extra care.
Possible side effects
Like all medicines, rizatriptan can cause side effects, although not everyone gets them. Often side effects improve as your body gets used to the new medicine.
|Side effects||What should I do?|
Rizatriptan interacts with a few medications and herbal supplements, so check with your doctor or pharmacist before starting rizatriptan or before starting any new medicines. It may also interact with some cold and flu preparations containing dextromethorphan such as Benadryl®.
The following links provide further information on rizatriptan.
Medsafe Consumer Information Sheet: Rizamelt®
- Treatment of acute migraine New Zealand Formulary
- Diagnosing and managing headache in adults in primary care BPAC, 2017
- The role of triptans in the treatment of migraine in adults BPAC, 2014
|Type of medicine||5HT1-receptor agonist (also known as a ‘triptan’)|
|Used for||Treatment of acute migraine attacks|
|Available as||Tablets, and wafers which dissolve in the mouth|
It is not clear what causes migraine. It is thought that some chemicals in the brain increase in activity, and as a result parts of the brain then send out confused signals which result in the symptoms of migraine. Why people with migraine should develop these chemical changes is also not clear. Many migraine attacks occur for no apparent reason, but for some people there may be things which trigger an attack, like certain foods or drinks.
Rizatriptan belongs to a class of medicines known as 5HT1-receptor agonists. They are also known simply as triptans. Triptans work by stimulating the receptors of a natural substance in the brain called serotonin (or 5HT). This eases the symptoms of migraine.
Rizatriptan is effective in relieving migraine attacks once the headache phase has started. It does not help prevent migraine headaches from developing.
Before taking rizatriptan
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking rizatriptan it is important that your doctor or pharmacist knows:
- If you are aged over 65 years or under 18 years.
- If you are pregnant or breast-feeding.
- If you have heart problems such as angina, or if you have had a heart attack.
- If you have high blood pressure.
- If you have circulation problems.
- If you have any problems with the way your liver works or with the way your kidneys work.
- If you have ever had a stroke or a transient ischaemic attack (this is also referred to as a TIA, or ‘mini-stroke’).
- If you have ever had an allergic reaction to a medicine.
- If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.
How to take rizatriptan
- Before you start this treatment, read the manufacturer’s printed information leaflet from inside your pack. The manufacturer’s leaflet will give you more information about rizatriptan and a full list of the side-effects which you may experience from taking it.
- Take rizatriptan exactly as your doctor tells you to. It is usual to take one tablet as soon as you start to feel a migraine headache develop.
- If you are taking a Maxalt® tablet, swallow the tablet with a drink of water. If you are taking a Maxalt® Melt wafer, this has been made so that you can place it on your tongue and allow it to dissolve in your mouth. Maxalt® Melt wafers are particularly helpful if drinking water to take a tablet would make you feel sick.
- If you have recently had a meal, rizatriptan may take a little longer before it starts to work than if you had not eaten. This is because the food in your stomach can delay the absorption of the medicine. Although rizatriptan is better taken when your stomach is empty, you can still take it if you have had a meal.
- If your migraine at first improves but then comes back again, you may take another tablet/wafer, providing it is at least two hours after you took the first one. If your migraine is not eased after taking the first dose, a further dose is unlikely to work, so do not take a second tablet/wafer.
- Do not take more than two 10 mg tablets in 24 hours.
Getting the most from your treatment
- Rizatriptan is meant to be used to treat headache pain during a migraine attack, not to stop the pain from coming on. You should wait until the pain is just beginning to develop, rather than taking it at the aura stage or when you feel that a migraine may be developing. Taking it earlier in a migraine attack will not stop the headache from developing.
- You should not take other migraine treatments such as other triptans or ergotamine at the same time as rizatriptan.
- Some people may benefit from taking a non-steroidal anti-inflammatory painkiller (such as naproxen) in addition to rizatriptan. Your doctor will advise you about this if it is recommended for you.
- If you find that rizatriptan does not relieve your migraine, make an appointment to discuss this with your doctor, as a different ‘triptan’ medicine may be more effective for you.
- If you buy any ‘over-the-counter’ medicines, check with your pharmacist which medicines are safe for you to take.
- It may help to keep a migraine diary. Note down when and where each migraine attack started, what you were doing, and what you had eaten that day. A pattern may emerge, and it may be possible to avoid one or more things that trigger your migraine attacks.
- Rizatriptan is used to treat migraine attacks, but there are other medicines that are available that may help to prevent you from having migraines. If you have migraines frequently, discuss this with your doctor.
- Some people who get frequent migraine attacks are in fact getting medication-induced headache. Medication-induced headache (also called medication-overuse headache) is caused by taking painkillers or triptans too often. If you use rizatriptan or painkillers on more than two days a week on a regular basis, you may be at risk of this. You should talk to your doctor if you suspect it.
Can rizatriptan cause problems?
Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with rizatriptan. You will find a full list in the manufacturer’s information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
|Common rizatriptan side-effects (these affect less than 1 in 10 people)||What can I do if I experience this?|
|Feeling tired, dizzy or sleepy||If this happens, do not drive and do not use tools or machines|
|Feeling sick (nausea), indigestion, diarrhoea||Stick to simple foods|
|Sore throat, tingling feelings, stiff or painful neck, feeling hot and flushed, dry mouth||If troublesome, speak with your doctor|
|Some people feel tightness or pain in their throat or chest||If the pain is intense, do not take any further tablets, and speak with your doctor about it|
If you experience any other symptoms that you think may be due to the medicine, speak with your doctor or pharmacist for advice.
How to store rizatriptan
- Keep all medicines out of the reach and sight of children.
- Store in a cool, dry place, away from direct heat and light.

- if you have phenylketonuria (PKU, an inherited condition in which a special diet must be followed to prevent mental retardation), you should know that the orally disintegrating tablets contain aspartame that forms phenylalanine.
What is Maxalt used for?
- Relieving migraine headaches.
Maxalt tablets and Maxalt melt tablets both contain the active ingredient rizatriptan, which is a type of medicine called a serotonin (or 5HT) agonist. This type of medicine is also commonly known as a ‘triptan’. It is a painkiller specifically used to relieve migraine attacks.
Although the cause of migraine attacks is not fully understood, it is thought that widening of blood vessels in the brain causes the throbbing pain of migraine headaches. Rizatriptan relieves this pain by causing the blood vessels in the brain to narrow.
Rizatriptan works by stimulating receptors called serotonin (or 5HT) receptors that are found in the brain. A natural substance called serotonin normally acts on these receptors, causing blood vessels in the brain to narrow. Rizatriptan mimics this action of serotonin by directly stimulating the serotonin receptors in the brain. This narrows the blood vessels and so relieves the pain of migraine headaches.
How do I take Maxalt?
- Your dose of rizatriptan should be taken as soon as possible after your migraine headache has started, though it is also effective if taken at a later stage during the migraine attack. It should not be taken during the aura, or warning phase that can occur before a migraine headache, as the safety and effectiveness of the medicine have not been established during this period, and the medicine will not prevent the headache.
- Maxalt melt tablets are designed to melt on the tongue in your saliva so they can be taken without needing a drink of water. They may be particularly useful for people who feel sick or vomit during their migraine attack and are unable to drink, as well as for people who can’t swallow conventional tablets.
- This medicine should preferably be taken on an empty stomach, because the presence of food in the stomach can delay the effect of the medicine for approximately an hour.
- If the first dose of this medicine doesn’t relieve your migraine headache then you should NOT take another dose for the same attack, as this has not been shown to be effective. (You can still take Maxalt for your next attack.)
- If the first dose does initially relieve your migraine, but the headache then comes back, you can take a second dose. However, if you need a second dose because your migraine has returned, you should NOT take it within two hours of your first dose. Do not take more than two doses in 24 hours.
- Do not exceed the recommended dose.
Important information about Maxalt
- This medicine should not be used to prevent migraines.
- This medicine should only be used by people with a clear diagnosis of migraine from their doctor.
- Using any painkillers for headaches too often or for too long can actually make the headaches worse. If you find you need to use this medicine frequently you should consult your doctor for advice.
- This medicine can cause feelings of warmth, heaviness, pressure, tightness, tingling or pain in certain parts of the body, including the chest or throat. Although sometimes very strong, these feelings usually only last a few minutes. If they continue or are particularly severe (especially chest pain), you should not take any more tablets and consult your doctor immediately.
- This medicine may cause drowsiness. If affected do not drive or operate machinery.
Maxalt should be used with caution in
- People with mild to moderately decreased kidney or liver function.
- People with risk factors for coronary heart disease, such as smoking, high cholesterol levels, high blood pressure (hypertension), diabetes, obesity, or a family history of heart disease.
- Men over 40 years of age.
- Post-menopausal women.
- People who suffer from phenylketonuria should be aware that Maxalt melt tablets contain aspartame, which is a source of phenylalanine.
Maxalt should not be used in
- People with severely decreased kidney or liver function.
- People who have had a heart attack.
- People with heart disease caused by inadequate blood flow to the heart (ischaemic heart disease), eg angina or a severe form of angina that occurs even at rest (Prinzmetal’s angina).
- People who have poor blood circulation in the legs or arms due to narrowing of blood vessels (peripheral vascular disease).
- Uncontrolled or moderate to severe high blood pressure (hypertension).
- People who have had a stroke or mini-stroke (transient ischaemic attack).
- A form of migraine associated with temporary paralysis of one side of the body (hemiplegic migraine).
- A type of migraine where there is a disturbance in brain function which initially presents with total blindness followed by dizziness, speach disturbances, ringing in the ears and double vision (basilar migraine).
- Maxalt tablets contain lactose and should not be taken by people with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption (this doesn’t apply to Maxalt melt tablets).
- This medicine is not recommended for children and adolescents aged under 18 years, or people aged over 65 years, as there is no information available regarding its safety and effectiveness in these age groups.
This medicine should not be used if you are allergic to one or any of its ingredients. Please inform your doctor or pharmacist if you have previously experienced such an allergy.
If you feel you have experienced an allergic reaction, stop using this medicine and inform your doctor or pharmacist immediately.
Pregnancy and breastfeeding
Certain medicines should not be used during pregnancy or breastfeeding. However, other medicines may be safely used in pregnancy or breastfeeding providing the benefits to the mother outweigh the risks to the unborn baby. Always inform your doctor if you are pregnant or planning a pregnancy, before using any medicine.
- The safety of this medicine for use during pregnancy has not been established. It is not recommended for use in pregnancy unless considered essential by your doctor. Seek medical advice from your doctor.
- This medicine may pass into breast milk. It is not recommended for use during breastfeeding unless considered essential by your doctor. If you are breastfeeding and your doctor recommends you to take this medicine, you should avoid breastfeeding for 24 hours after taking the medicine, and any milk expressed during this time should be discarded. Seek further medical advice from your doctor.

If you think you have experienced a side effect from a medicine or vaccine you should check the patient information leaflet. This lists the known side effects and what to do if you get them. You can also get advice from your doctor, nurse or pharmacist. If they think it’s necessary they’ll report it for you.
You can also report side effects yourself using the yellow card website: www.mhra.gov.uk/yellowcard.
Can I take Maxalt with other medicines?
It is important to tell your doctor or pharmacist what medicines you are already taking, including those bought without a prescription and herbal medicines, before you start treatment with this medicine. Similarly, check with your doctor or pharmacist before taking any new medicines while taking this one, to make sure that the combination is safe.
Do not take this medicine if you have taken ergotamine or its derivatives, eg dihydroergotamine or methysergide, in the previous 24 hours. These medicines should not be taken within six hours of taking rizatriptan.
If your first dose of rizatriptan does not work to relieve your migraine, it is fine to take a painkiller containing aspirin, paracetamol, or a non-steroidal anti-inflammatory drug (NSAID), such as ibuprofen. However, as noted above, you should not take ergotamine, dihydroergotamine or methysergide for at least six hours after taking rizatriptan.
This medicine must not be taken in combination with other 5HT agonists (triptans), eg sumatriptan, zolmitriptan, frovatriptan, naratriptan, eletriptan, almotriptan.
There may be an increased risk of a rare side effect called the serotonin syndrome if rizatriptan is taken by people taking other medicines that enhance the activity of serotonin in the central nervous system, such as the following. You should not take this medicine if you are taking any of these:
- dapoxetine (don’t take rizatriptan if you’ve taken this in the last week)
- monoamine oxidase inhibitor antidepressants (MAOIs), eg phenelzine, tranylcypromine, isocarboxazid or moclobemide (don’t take rizatriptan if you’ve taken one of these in the last two weeks)
- selective serotonin re-uptake inhibitor antidepressants (SSRIs), such as citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine or sertraline
- selegiline (don’t take rizatriptan if you’ve taken this in the last two weeks)
