Risedronate (Actonel) is a first-choice medication used to treat osteoporosis (bone loss or weakening). It can help improve bone mineral density (BMD) and lower the risk of bone fractures. There are several dosing options and a delayed-release form in case a particular dosing schedule is more convenient for some people.
Osteoporosis in women who have gone through menopause (postmenopause)
Osteoporosis in men
Osteoporosis caused by long-term corticosteroid use
Paget's disease
Risedronate (Actonel) is a bisphosphonate. Bisphosphonates work to slow down bone breakdown so the body can make new, healthy, and strong bone. Risedronate (Actonel) helps raise BMD, which is a measure of how dense your bones are. A higher BMD means your bones are stronger, which helps lower your risk of bone fractures.

Don't take risedronate (Actonel) and Atelvia at the same time, since they contain the same active ingredient. Taking two medications that have the same ingredient together can raise your risk of side effects.
If you're not taking the tablet once a day, mark the dates of your scheduled doses on your calendar to help you remember when to take your medication.
If you're taking risedronate (Actonel), take the whole tablet first thing in the morning with a full glass of plain water (6 oz to 8 oz) while standing or sitting upright. This lowers your risk of irritating your esophagus. Also, don't eat or drink anything (except plain water) after taking so your body can absorb the medication well.
If you're taking Atelvia delayed-release tablets, take the whole tablet in the morning right after you eat with at least 4 oz of plain water. Doing so can help lower your risk of stomach pain. Also, don't chew, cut, or crush the tablet. The outer coating of the tablet makes sure that the medication doesn't get released into your body until after it reaches your stomach to help lower stomach problems.
Take risedronate (Actonel) or Atelvia with plain water and not mineral water. Mineral water can contain more calcium, which can block the medication from working as well.
Don't chew or suck on the tablet. Also, don't lie down for at least 30 minutes after taking the tablet. Doing so can cause ulcers and irritation in your throat.
Don't take other medications or supplements (like calcium, antacids, or vitamins) for at least 30 minutes after taking the tablet. Some medications can block risedronate (Actonel) from working as well in the body.
It's important to have good mouth care when taking this medication to lower the risk of jaw problems. Let your dentist know you're taking risedronate (Actonel) before starting the medication.
You can take calcium and vitamin D supplements along with the medication to prevent low calcium levels and help your bones grow stronger.
If you have trouble swallowing, pain when you swallow, chest or stomach pain, new or worsening heartburn, or any pain around your hips, thighs, or jaw, tell your healthcare provider right away.
Risedronate (Actonel) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: History of ulcers or other digestive problems | Taking with aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs) | Not drinking enough water when taking risedronate (Actonel) | Lying down after taking risedronate (Actonel)
Stomach and esophagus irritation, including heartburn, pain, and ulcers, can happen after taking risedronate (Actonel). To help prevent irritation, it's very important to follow the directions on how to take the medication and any other directions your provider has given you. Take risedronate (Actonel) or Atelvia with a full glass of plain water while standing or sitting upright, and avoid lying down for at least 30 minutes. Stop taking risedronate (Actonel) right away and talk to a healthcare provider if you notice you have trouble swallowing, new pain with swallowing, pain around the middle of your chest, or new or worsening heartburn while taking this medication.
Risk factors: Gum or dental disease or surgery | Anemia (low red blood cell count) | Bleeding problems | Cancer | Taking cancer medications at the same time | Poor mouth care or dentures that don't fit well | Taking risedronate (Actonel) for a long time
Although rare, risedronate (Actonel) can break down and weaken the jawbone. This breakdown is more likely if you get a tooth extraction, dental implants, bone surgery around or in your mouth, or an infection in the mouth that hasn't healed while taking risedronate (Actonel). Keeping your teeth healthy with regular brushing and flossing can lower your risk of this problem. If you notice pain or swelling in your jaw, talk to your doctor or dentist right away. It's also important to let your dentist know that you're taking risedronate (Actonel). You might need to complete any necessary dental work before starting the medication.
Though rare, some people taking risedronate (Actonel) have had severe pain in their bones, joint, or muscles. It can happen as quickly as one day to several months after starting this medication. Generally, the pain improves after stopping the medication. If you feel severe pain in these areas, talk to a healthcare provider, as you might need to stop risedronate (Actonel).
Risk factors: Taking corticosteroid medications at the same time
Very rarely, leg bone fractures can happen without any known cause in people taking risedronate (Actonel). If you notice new dull or aching pain in your hips or thighs, tell your healthcare provider right away. You might need to stop taking risedronate (Actonel).
Risk factors: History of low calcium in the blood
Risedronate (Actonel) can lower the calcium levels in your blood. If you have low calcium levels, you'll need to be treated before starting risedronate (Actonel) to prevent this problem from getting worse. To help keep your calcium levels from getting too low, you might need to take calcium and vitamin D supplements. Talk to your healthcare provider if you notice muscle spasms or twitching, or numbness and tingling in your fingers, toes, or around your mouth, as these can be signs of low calcium levels.
Postmenopausal osteoporosis: There are different dosing options for risedronate (Actonel) depending on how often you would like to take it: 5 mg by mouth once a day, 35 mg once a week, 75 mg on 2 consecutive days each month, or 150 mg once a month.
Osteoporosis in men: The typical dose is 35 mg by mouth once a week.
Osteoporosis caused by long-term corticosteroid use: The typical dose is 5 mg by mouth once daily.

Using this medicine with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
