About rimegepant for migraine headache

Rimegepant can be used to treat an active migraine headache or to prevent migraine attacks from happening. Although it is not known exactly how rimegepant works, it is known to block the action of a substance called calcitonin gene-related peptide (CGRP) by attaching to its receptor sites in the brain. People with migraine may have raised levels of CGRP. By blocking the effects of CGRP, rimegepant can stop an active migraine attack and also reduce the number of attacks over time.

In people with migraine, it is thought that some chemicals in the brain increase in activity. As a result, parts of the brain then send out confused signals which result in the symptoms of headache and sickness (nausea and vomiting). Why people with migraine should develop these chemical changes is not clear, but for some people there may be things which trigger an attack, like certain foods or drinks.

Before taking rimegepant

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 rimegepant it is important that your doctor knows:

• إذا كنتِ حاملاً، تحاولين الإنجاب، أو تقومين بالرضاعة الطبيعية.

• If you have any problems with the way your kidneys work or the way your liver works.

• إذا كنت قد تعرضت في أي وقت مضى لرد فعل تحسسي تجاه دواء.

• إذا كنت تتناول أي أدوية أخرى. يشمل ذلك أي أدوية تتناولها والتي يمكن شراؤها بدون وصفة طبية، بالإضافة إلى الأدوية العشبية والمكملات الغذائية.

تحقيق أقصى استفادة من علاجك

• Try to keep all your regular appointments with your doctor. This is so your doctor can check on your progress.

• If you find that rimegepant does not relieve or prevent your migraines, make an appointment to discuss this with your doctor, as an alternative medicine may be more effective for you.

• 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 for you to avoid some of the things that trigger your migraine attacks.

• Some people may benefit from taking a non-steroidal anti-inflammatory painkiller (such as ibuprofen) in addition to rimegepant. Your doctor will advise you about this if it is recommended for you.

• Some medicines can affect how well rimegepant works. Your doctor or pharmacist will advise you on this, and you will find a full list in the manufacturer's information supplied with your pack.

• If you buy any medicines, check with your doctor or a pharmacist that they are suitable for you to take with rimegepant. You should not take the herbal medicine St John's wort while you are being treated with rimegepant..

• 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 too often. If you use 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.

• If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking rimegepant.
