About mefenamic acid

Anti-inflammatory painkillers like mefenamic acid are also called non-steroidal anti-inflammatory drugs (NSAIDs), or sometimes just 'anti-inflammatories'. Mefenamic acid is used to treat painful conditions such as דלקת פרקים, pain associated with דימום וסת כבד, and pain after surgical operations.

Mefenamic acid works by blocking the effect of natural chemicals called cyclo-oxygenase (COX) enzymes. These enzymes help to make other chemicals in the body, called prostaglandins. Some prostaglandins are produced at sites of injury or damage, and cause pain and inflammation. By blocking the effect of COX enzymes, fewer prostaglandins are produced, which means pain and inflammation are eased.

Before taking mefenamic acid

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 mefenamic acid, it is important that your doctor knows:

• אם אי פעם היה לך כיב קיבה או כיב בתריסריון, או אם יש לך מחלת מעי דלקתית כמו מחלת קרוהן או קוליטיס כיבית.

• אם יש לך אסתמה או כל הפרעה אלרגית אחרת.

• אם את בהריון, מנסה להיכנס להריון, או מניקה.

• אם יש לך בעיות בתפקוד הכבד שלך, או אם יש לך בעיות בתפקוד הכליות שלך.

• אם יש לך מצב לב או בעיה בכלי הדם או במחזור הדם.

• אם יש לך לחץ דם גבוה.

• אם יש לך בעיות בקרישת דם.

• אם יש לך אפילפסיה.

• אם יש לך רמות סוכר בדם או כולסטרול גבוהות.

• אם יש לך הפרעה ברקמת חיבור כמו זאבת מערכתית. זהו מצב דלקתי הנקרא גם זאבת או SLE.

• אם יש לך הפרעת דם תורשתית נדירה הנקראת פורפיריה.

• If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as as herbal and complementary medicines.

• אם אי פעם הייתה לך תגובה אלרגית לכל NSAID אחר (כגון אספירין, איבופרופן, דיקלופנק ואינדומטצין), או לכל תרופה אחרת.

How to take mefenamic acid

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

• Take mefenamic acid exactly as your doctor tells you to. The usual dose is 500 mg, which is taken as two 250 mg capsules, or one 500 mg tablet. You will be asked to take this dose three times a day. If you are taking it for period pain, your doctor will likely suggest that you take it for a few days each month, starting on your first day of bleeding.

• Take mefenamic acid with food. This will help to protect your stomach from side-effects such as indigestion.

• If you forget to take a dose, take it as soon as you remember unless your next dose is due. If your next dose is due, then take the dose which is due but leave out the forgotten one. Do not take two doses together to make up for a missed dose.

להפיק את המרב מהטיפול שלך

• Your doctor will try to prescribe you mefenamic acid for the shortest time possible to reduce the risk of side-effects. If you need to take it over a long period of time, your doctor may want to prescribe another medicine along with it to protect your stomach from irritation.

• Try to keep any regular appointments with your doctor. This is so your doctor can check on your progress. It is especially important if you are taking mefenamic acid for a long-term condition.

• If you have asthma, symptoms such as wheeze or breathlessness can be made worse by anti-inflammatories. If this happens to you, you should stop taking mefenamic acid and see your doctor as soon as possible.

• There is known to be a small increased risk of heart and blood vessel problems in people taking some anti-inflammatory painkillers long-term. Your doctor will explain this to you and will prescribe the lowest suitable dose for the shortest time in order to reduce the risk. Do not take more than the recommended dose.

• If you buy any medicines, check with a pharmacist that they are suitable for you to take. This is because you should not take mefenamic acid with any other anti-inflammatory painkiller, some of which are available in cold and flu remedies which can be bought 'over the counter'.

• אם אתה עובר ניתוח או טיפול שיניים, אמור לאדם שמבצע את הטיפול אילו תרופות אתה נוטל.
