Rizatriptan bei Migräne

About rizatriptan

Es ist nicht klar, was Migräne auslöst. Es wird vermutet, dass einige chemische Stoffe im Gehirn ihre Aktivität erhöhen und Teile des Gehirns daraufhin verwirrte Signale aussenden, die zu den Migränesymptomen führen. Warum Menschen mit Migräne diese chemischen Veränderungen entwickeln sollten, ist ebenfalls unklar. Viele Migräneanfälle treten ohne ersichtlichen Grund auf, aber bei manchen Menschen gibt es Dinge, die einen Anfall auslösen, z. B. bestimmte Nahrungsmittel oder Getränke.

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:

• Wenn Sie über 65 Jahre oder unter 18 Jahre alt sind.

• Wenn Sie schwanger sind oder stillen.

• If you have heart problems such as angina, or if you have had a heart attack.

• Wenn Sie unter hohem Blutdruck (Hypertonie) leiden.

• Wenn Sie Kreislaufprobleme haben.

• Wenn Sie Probleme mit der Funktionsweise Ihrer Leber oder Ihrer Nieren haben.

• Wenn Sie schon einmal einen Schlaganfall oder eine transitorische ischämische Attacke (auch TIA oder "Mini-Schlaganfall" genannt) erlitten haben.

• Wenn Sie schon einmal eine allergische Reaktion auf ein Arzneimittel hatten.

• Wenn Sie andere Arzneimittel einnehmen oder verwenden. Dazu gehören alle Arzneimittel, die Sie einnehmen und die rezeptfrei erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.

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.

Das Beste aus Ihrer Behandlung herausholen

• 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.

• Wenn Sie rezeptfreie Medikamente kaufen, erkundigen Sie sich bei Ihrem Apotheker, welche Medikamente Sie unbedenklich einnehmen können.

• Es kann helfen, ein Migränetagebuch zu führen. Notieren Sie, wann und wo jede Migräneattacke begann, was Sie an diesem Tag taten und was Sie gegessen haben. Vielleicht lässt sich ein Muster erkennen, und Sie können eines oder mehrere Dinge vermeiden, die Ihre Migräneanfälle auslösen.

• 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 with 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.

Wenn Sie andere Symptome haben, von denen Sie glauben, dass sie auf das Arzneimittel zurückzuführen sind, fragen Sie Ihren Arzt oder Apotheker um Rat.
