Take risedronate sodium tablets first thing after you get up in the morning. Swallow the tablet whole with a large glass of plain water, at least half an hour before you have breakfast. Remain sitting or standing upright for at least 30 minutes after taking the tablet.
Each time you collect a prescription, make sure you have been given the same strength of tablet as you have had before. This is because there are three different strengths of risedronate sodium tablets and not all will be suitable for you.
If you buy any medicines 'over the counter', make sure your pharmacist knows that you are taking a bisphosphonate medicine, as some medicines will prevent risedronate sodium from working properly.
Good dental hygiene is particularly important with this treatment - this means that you must brush your teeth regularly, and have routine dental check-ups.

About risedronate sodium
סוג התרופה | A bisphosphonate |
שימוש עבור | Osteoporosis; Paget's disease of bone |
נקרא גם | Actonel®, Actonel Once A Week®; |
זמין כ | טבליות |
Risedronate sodium, a bisphosphonate medicine, is prescribed for the treatment of two conditions which affect the bones. It is prescribed as a treatment for 'thinning' of the bones (אוסטאופורוזיס), and it is also used to prevent bone damage in people with Paget's disease of bone.
Osteoporosis is a bone disease which causes bones to become brittle and fragile, making them prone to breaks and fractures. During our lifetime, old bone tissue is constantly being broken down and replaced by new bone. As we get older, our bone begins to lose density because old bone is lost faster than new bone can replace it. Women in particular have an increased risk of developing osteoporosis because they lose bone material rapidly after the menopause. Risedronate sodium slows down the rate at which old bone is lost. New bone continues to be made and this leads to an overall increase in bone density, which reduces the risk of broken bones and fractures. Bones also need calcium and colecalciferol (vitamin D3) to help keep them strong and healthy.
In Paget's disease of bone, risedronate sodium works on bones to make them stronger and help prevent bone thickening. This helps ease symptoms such as pain, bone damage and fracture.

How to take risedronate sodium
חזרה לתוכןBefore you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about risedronate sodium, and it will also provide you with a full list of the side-effects which you could experience from taking it.
Take the tablets exactly as your doctor tells you to. There are three strengths of risedronate sodium tablets available - 5 mg, 30 mg and 35 mg. The 30 mg tablets are prescribed for people with Paget's disease, whereas people being treated for 'thinning' of the bones (osteoporosis) will receive either the 5 mg or 35 mg strength tablet. Depending upon which strength of tablet you are prescribed, your doctor will ask you to take either one dose each day או one dose each week. As a guide, if you are given 5 mg or 30 mg tablets, these are taken each day. If you are given 35 mg tablets, these are taken on one day of the week only. If you are unsure about how often to take your tablets, ask your pharmacist or doctor for further advice.
Take your tablet first thing after getting up in the morning. Swallow your tablet whole (do not crush or chew the tablet). Take it with a large glass of plain water, at least 30 minutes before you have any food, or other drinks or medicines. It is important that you remain sitting or standing upright for at least 30 minutes afterwards - this is to stop the tablet from getting stuck in your throat or doing any damage before it reaches your stomach.
If you forget to take your tablet first thing in the morning, you can take it when you remember later in the day, provided that you do not eat food or have anything to drink during the two hours before you take the tablet, or during the two hours afterwards. It is particularly important you do not have any milk, or any drinks containing milk during this time. If this is not possible, or if it is getting near to bedtime, then do not take a tablet on that day. If you normally take risedronate each day, just carry on as usual the next day - do not take a double dose to make up for the missed tablet. If you usually take risedronate just once a week, then take the missed dose on the following day, and then take your next dose on your usual day of the week.
If you are taking Actonel® Combi, this is a combination treatment which contains risedronate sodium tablets (Actonel®) and sachets which contain granules of calcium and colecalciferol. It is a treatment for women. You will be asked to take one Actonel® tablet on the first day of every week and one sachet of granules for the other six days of the week. Follow the instructions above for taking the tablets. To take the granules, dissolve the contents of one sachet into a glass of water, stir it to mix, and then drink it as soon as the fizzing has stopped. Foods which contain spinach, rhubarb and whole cereals can prevent you from absorbing the full amount of calcium - it is best to avoid these types of food for the two hours before and the two hours after taking the granules. Never take risedronate tablets on the same day as you take the sachets.

חזרה לתוכןDo not take any mineral supplements or any indigestion remedies, or anything which might contain iron or calcium during the two hours before and the two hours after taking risedronate sodium. This is because these things interfere with risedronate sodium and stop it from being absorbed by your body. Also, you should never take risedronate sodium tablets before you get out of bed in the morning, or at bedtime.
Remember to keep your regular appointments with your doctor so that your progress can be monitored.
Good dental hygiene is important during treatment with this medicine - this means that you must brush your teeth regularly and have regular dental check-ups. You should also make sure that your dentist is aware that you are taking risedronate sodium, as some dental treatments may not be recommended for you while you are taking the tablets.
Treatment with risedronate sodium will last several months or longer. Continue to take the tablets until you are advised otherwise by your doctor.
It may be necessary for you to take supplements of calcium and vitamin D alongside this treatment. If so, your doctor will prescribe these for you.
If you buy any medicines, check with a pharmacist that they are suitable for you to take. This is because mineral supplements, iron preparations, and some indigestion remedies reduce the amount of risedronate sodium which your body absorbs. This could make your treatment less effective.
Eating a well-balanced diet and taking regular exercise can help your bones stay strong. Remember to follow any exercise or dietary advice your doctor gives to you.
Chemicals from tobacco can get into your bloodstream and can affect your bones, making bone loss worse. If you smoke, you should make every effort to stop. Ask your doctor or pharmacist for advice on stopping.

שאלות נפוצות
What is the specific role of risedronate sodium in treating osteoporosis?
Risedronate sodium slows down the rate at which old bone is lost. Since new bone continues to be made, this leads to an overall increase in bone density, which in turn reduces the risk of broken bones and fractures.
Can I take risedronate sodium at any time during the day if I forget my morning dose?
If you forget your tablet first thing in the morning, you can take it later in the day. However, it's crucial that you haven't eaten or had anything to drink for two hours before taking the tablet, and you must also avoid food or drink for two hours afterwards. This includes milk or milk-containing drinks. If these conditions can't be met, or if it's getting close to bedtime, do not take the tablet on that day.
What are the key instructions for taking the Actonel® Combi granules?
If you are prescribed Actonel® Combi and need to take the granules, dissolve the contents of one sachet into a glass of water. Stir it to mix, and then drink it as soon as the fizzing has stopped. It's best to avoid foods containing spinach, rhubarb, and whole cereals for two hours before and two hours after taking the granules, as they can prevent you from absorbing the full amount of calcium. Remember, never take risedronate tablets on the same day as you take the sachets.
Are there any foods or drinks I should avoid when taking risedronate sodium, besides those mentioned for Actonel® Combi?
Yes, you should avoid taking any mineral supplements, indigestion remedies, or anything that might contain iron or calcium during the two hours before and the two hours after taking risedronate sodium. These items can interfere with the medicine and prevent your body from absorbing it properly, which could make your treatment less effective. This also applies specially to milk and milk-containing drinks when taking the tablet if you've missed your morning dose.
How long will I need to continue taking risedronate sodium?
Treatment with risedronate sodium will likely last several months or even longer. You should continue to take the tablets exactly as prescribed until your doctor advises you otherwise.
What should I do if I experience heartburn, pain or difficulty swallowing after taking the tablets?
Heartburn, pain, or difficulty swallowing can be serious side-effects. You should stop taking the tablets and speak with your doctor as soon as possible if you experience these symptoms, as they may indicate that the tablets are irritating your throat.
