Ranolazine for angina

About ranolazine for angina

אנגינה is a pain that comes from the heart. It is usually caused by the narrowing of one or more of the arteries that supply blood to your heart. This narrowing reduces the blood supply to parts of your heart muscle. When your heart needs more blood and oxygen than it can get through the narrowed arteries (for example, when you walk fast or climb stairs), you feel angina pain.

Ranolazine is taken in addition to other medicines used to prevent angina pain. You will be prescribed it if the other anti-anginal medicines you are taking are not sufficiently controlling your chest pains.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking ranolazine it is important that your doctor knows:

• אם את בהריון או מניקה.

• If you know you have an irregular heart rhythm.

• If you have been told you have heart failure, which is a condition where your heart is not working as well as it should.

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

• אם אי פעם הייתה לך תגובה אלרגית לתרופה.

• אם אתה נוטל או משתמש בתרופות אחרות כלשהן. זה כולל כל תרופה שאתה נוטל שניתן לרכוש ללא מרשם, כמו גם תרופות צמחיות ומשלימות.

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about ranolazine and will also provide you with a full list of side-effects which you could experience from taking it.

• Take ranolazine exactly as your doctor tells you to. It is usual to take one tablet two times a day. When starting your treatment your doctor will give you a smaller-strength tablet (375 mg tablet) and may then gradually increase your dose to a 500 mg or a 750 mg strength of tablet. This allows your doctor to make sure that you have the dose that helps your condition but avoids any unwanted symptoms.

• Try to take your doses at the same times of day each day, as this will help you to remember to take them regularly. You can take ranolazine either before or after a meal. Swallow the tablet whole (without chewing or crushing it) with a drink of water.

• If you forget to take a dose at your usual time, take it when you remember. However, if it is nearly time to take your next dose then leave out the forgotten dose and take your next dose when it is due. Do not take two doses together to make up for a missed dose.

• Ranolazine tablets are not suitable to take to relieve pain if you are having an angina attack. Your doctor will also prescribe a nitrate medicine, such as glyceryl trinitrate (GTN), for you to take if this happens. If after using GTN your pain has not eased within a few minutes, call for an ambulance.

• נסה לשמור על הפגישות הקבועות שלך עם הרופא. זה כדי שהרופא יוכל לבדוק את ההתקדמות שלך.

• Treatment with ranolazine is usually long-term unless you experience an adverse effect. Continue to take the tablets unless you are advised otherwise by your doctor.

• Do not drink grapefruit juice while you are on ranolazine. This is because a chemical in grapefruit juice increases the amount of ranolazine in your bloodstream. This makes side-effects more likely.

• It is important if you buy any medicines 'over the counter' to check with a pharmacist that they are suitable for you to take. Some medicines and herbal remedies should not be taken with ranolazine.

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 ranolazine. 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.

• שמור את כל התרופות מחוץ להישג ידם וראייתם של ילדים.
