Uses

What is risedronate used for?

Risedronate is commonly used for the following conditions.

  • Treatment or prevention of osteoporosis in women after menopause. Osteoporosis is a condition in which your bones become thin and weak and may break more easily.
  • Treatment of osteoporosis in men
  • Treatment or prevention of osteoporosis caused by steroid drug therapy
  • Treatment of Paget’s Disease, a condition in which your body’s natural bone-building process is disrupted, causing your bones to become weak and misshapen

Risedronate may also be used for other conditions as determined by your healthcare provider.

How does risedronate work (mechanism of action)?

Risedronate slows the natural breakdown of your bones. This helps them stay stronger and reduces the risk for bone fractures.

What are the serious side effects of risedronate?

While less common, the most serious side effects of risedronate are described below, along with what to do if they happen.

Severe Allergic Reactions. Risedronate may cause allergic reactions, which can be serious. Stop taking risedronate and get help right away if you have any of the following symptoms of a serious allergic reaction.

  • Breathing problems or wheezing
  • Racing heart
  • Fever or general ill feeling
  • Swollen lymph nodes
  • Swelling of the face, lips, mouth, tongue, or throat
  • Trouble swallowing or throat tightness
  • Itching, skin rash, or pale red bumps on the skin called hives
  • Nausea or vomiting
  • Dizziness, feeling lightheaded, or fainting
  • Stomach cramps
  • Joint pain

Esophagus Problems. Taking risedronate by mouth may irritate the esophagus or upper part of your gastrointestinal (GI) tract. This irritation can be worse in people who already have stomach or esophagus problems. In some cases, it can lead to problems such as ulcers, bleeding, or tears in the esophagus, which may require hospitalization. To reduce the risk of these problems, it is important to take a risedronate tablet with a full glass of plain water and stay upright after taking it. Stop taking risedronate and call your healthcare provider right away if you have any of the following symptoms.

  • Trouble or pain while swallowing 
  • Chest pain
  • New or worsening heartburn

Low Calcium Level (Hypocalcemia). Risedronate can cause low calcium levels, also known as hypocalcemia, which can be serious. Decreased calcium levels can cause a rare dangerous heart rhythm problem called QT prolongation and torsade de pointes. Some people have a higher risk of this, including people who are older, have other people in their family who have had these conditions, have low potassium or magnesium, or who take some medicines for other heart rhythm problems. Call your healthcare provider if you have any of the following symptoms.

  • Changes in your heart rate or rhythm, such as fast or skipping heartbeat
  • Fainting
  • Numbness, tingling, or burning sensation in your arms, feet, or face (paresthesia)
  • Muscle pain, spasms, twitching, or cramps
  • Seizures

Severe Pain in the Bones, Joints, or Muscles. Risedronate may cause severe pain in the bones, joints, or muscles (musculoskeletal pain). The pain can be severe enough that it could be difficult to carry out normal activities. Call your healthcare provider if you experience severe pain while on risedronate.

Severe Jawbone Problems (Osteonecrosis). Risedronate can rarely cause severe jawbone problems, also called osteonecrosis of the jaw. In this condition, your jawbone may get damaged due to reduced blood flow. You may be at higher risk if you are undergoing certain dental procedures (such as a tooth extraction or dental implants), if you have poor oral health, or if you have cancer or certain other conditions. You may be told to see a dentist before starting risedronate and to practice good mouth care. Call your healthcare provider right away if you experience any of the following symptoms of jaw osteonecrosis.

  • Jaw pain or discomfort
  • Mouth sores
  • Loose teeth

Unusual Thigh Bone Fractures. Risedronate may cause an increased risk for fractures in your thigh bone, even with a light force. Call your healthcare provider if you experience new or unusual pain in your thigh, hip, or groin.

Warnings & Precautions

Who should not use risedronate?

Allergies to Ingredients. People who are allergic to any of the following should not take risedronate.

  • Actonel
  • Any of the ingredients in the specific product dispensed

Your pharmacist can tell you all of the ingredients in the specific risedronate products they stock.

Low Calcium Levels (Hypocalcemia). Risedronate can cause low calcium levels, also known as hypocalcemia. It should not be used if you have low blood calcium levels.

Kidney Problems. Risedronate should not be taken if your kidneys are not working as well as they should be. If there is a concern about the health of your kidneys, your healthcare provider may do tests to determine if they are working well enough for you to take this medicine.

What should I know about risedronate before using it?

Do not take risedronate unless it has been prescribed to you by a healthcare provider. Take it as prescribed.

Do not share risedronate with other people, even if they have the same condition as you. It may harm them.

Keep risedronate out of the reach of children.

Take the risedronate tablet after you get up for the day. Take it on an empty stomach, at least 30 minutes before the first food or drink (other than plain water) of the day and before taking any other medicines or supplements. Risedronate will work only if it is taken on an empty stomach. 

Do not eat or drink anything except plain water, or take other medicines for at least 30 minutes after taking a risedronate tablet. Do not take it with mineral water, coffee, tea, soda, or juice. These may make risedronate not work as well. See the Interactions section for more details. 

Swallow the tablet whole with a full glass (6 to 8 ounces) of plain water to lower the risk of irritation of the esophagus. Sit upright or stand when you take a risedronate tablet and afterwards. Do not lie down for at least 30 minutes after you take it. You may sit, stand, walk, or do other activities where you are upright (like reading). 

Do not chew or suck on risedronate tablets. This could lead to irritation or sores in the mouth or throat.

Tell your healthcare provider about all of your health conditions and any prescription or over-the-counter (OTC) medicines, vitamins/minerals, herbal products, and other supplements you are using. This will help them determine if risedronate is right for you.

In particular, make sure that you discuss any of the following.

Risedronate can irritate your digestive tract and worsen these conditions.
