What is Actonel?
Actonel (risedronate) is a bisphosphonate medicine that alters bone formation and breakdown in the body. This can slow bone loss and may help prevent bone fractures.
Actonel is used to treat or prevent osteoporosis caused by menopause, steroid use, or gonadal failure.
Actonel is also used to increase bone mass in men who have osteoporosis, and to treat Paget's disease of bone in men and women.

In rare cases, this medicine may cause bone loss (osteonecrosis) in the jaw. Symptoms include jaw pain or numbness, red or swollen gums, loose teeth, or slow healing after dental work. The longer you use risedronate, the more likely you are to develop this condition.
Osteonecrosis of the jaw may be more likely if you have cancer or received chemotherapy, radiation, or steroids. Other risk factors include blood clotting disorders, anemia (low red blood cells), and a pre existing dental problem.

How should I take Actonel?
Actonel tablets come in different strengths (number of milligrams per pill) that are taken on different schedules. You may need to take a tablet once per day, once per week, once per month, or for 2 days in a row once per month.
Your dosing schedule will depend on why you are taking Actonel and in what tablet strength. If you change strengths, you may also need to change your schedule.
Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Take the Actonel tablet first thing in the morning with a full glass (6 to 8 ounces) of water, at least 30 minutes before you eat or drink anything or take any other medicine.

Before you take your first food or drink except for plain water.
-
Before you take other medicines including vitamins, calcium, iron, antacids, or laxatives.
Take this medicine at the same time each day or on the same day each week or each month (depending on your dosing schedule).
Pay special attention to your dental hygiene while taking risedronate. Brush and floss your teeth regularly. If you need to have any dental work (especially surgery), tell the dentist ahead of time that you are using risedronate.
Actonel is only part of a complete program of treatment that may also include diet changes, exercise, bone mineral density testing, and taking calcium and vitamin supplements. Follow your doctor's instructions very closely.

Your doctor will determine how long to treat you with this medicine. Actonel is often given for only 3 to 5 years.
What happens if I miss a dose?
Once-daily dosing: If you forget to take Actonel first thing in the morning, do not take it later in the day. Wait until the following morning and skip the missed dose. Do not take two (2) doses in one day.
Once-per-week or once-per-month dosing: If you forget to take Actonel on your scheduled day, take it first thing in the morning on the day after you remember the missed dose. Then return to your regular weekly or monthly schedule on your chosen dose day. Do not take 2 doses in one day.
