Actonel (Risedronate) Dosage and Side Effects
ACTONEL is used to prevent and treat osteoporosis.
Proper Use of this medication
As with all medications, it is important to take as directed by your doctor.
Daily dose (ACTONEL 5 mg or 30 mg tablet):
If you forget to take your dose, do not double your next dose (i.e., do not take 2 tablets on the same day). Simply take 1 tablet at your next scheduled time.
Weekly dose (35 mg ACTONEL tablet or 35 mg ACTONEL DR tablet):
If you forget to take your dose on the regularly scheduled day, simply take 1 tablet on the day you first remember having missed your dose. Then resume your schedule by taking 1 tablet on the originally chosen day of the week. If you've missed your dose by exactly one week, do not take 2 tablets on the same day. Simply take 1 tablet as you normally would have on this day and resume your usual weekly schedule.
Monthly duet dose (ACTONEL 75 mg tablet):
If you miss one or both tablets of your dose of ACTONEL 75 mg in the morning, do not take it later in the day. If the next month's scheduled doses are more than 7 days away do the following:
- If both tablets were missed, take the first ACTONEL 75 mg tablet on the morning after the day it is remembered and the second tablet on the next consecutive morning.
- If only one tablet is missed, take the missed tablet on the morning after the day it is remembered.
You should then continue your usual schedule of ACTONEL 75 mg on two consecutive days each month. Do not take more than two 75 mg tablets within 7 days.
If the next month's scheduled doses are 1 to 7 days away, you should wait until next month's scheduled doses and then resume taking ACTONEL 75 mg on two consecutive days each month as originally scheduled.
Once monthly dose (ACTONEL 150 mg tablet):
If you miss the 150 mg dose of ACTONEL (1 tablet of 150 mg) in the morning, do not take it later in the day. If the next month's scheduled dose is more than 7 days away, take the missed tablet on the morning after the day it is remembered. You should then return to your usual schedule of ACTONEL 150 mg.
If the next month's scheduled dose is 1 to 7 days away, you should wait until next month's scheduled dose and then resume taking ACTONEL 150 mg as originally scheduled. Do not take more than 150 mg of ACTONEL within 7 days.
ACTONEL may cause problems in your esophagus, stomach and intestines, including ulcers. If you have trouble or pain upon swallowing, heartburn, chest pain and black or bloody stools, stop taking ACTONEL and tell your doctor right away.
ACTONEL side effects:
In clinical studies of osteoporosis with ACTONEL, the most commonly reported side effects were abdominal pain, heartburn and nausea. In studies of Paget's disease, diarrhea and headache were also commonly reported. ACTONEL may cause pain in bones, joints or muscles, rarely severe. Pain may start as soon as one day or up to several months after starting ACTONEL. ACTONEL at monthly doses may cause short-lasting, mild flu-like symptoms. These symptoms usually decrease after subsequent doses.

Interactions with this medication
It is important to tell your health care providers, including doctors and dentists, about all medications you are taking, even if the medicine does not require a prescription (including vitamin and herbal supplements).
You should not take ACTONEL with food, as it may prevent your body from absorbing or using ACTONEL. You should take ACTONEL on an empty stomach.
Vitamins, mineral supplements, antacids and other medications may contain substances (e.g., calcium, magnesium, aluminum, and iron) which can stop your body from absorbing or using ACTONEL. These medications should be taken at a different time of day than ACTONEL.
If you are taking ACTONEL for Paget's disease, talk to your doctor before taking ASA or other non-steroidal anti-inflammatory drugs used for pain management because the risk of stomach upset may be increased.
ACTONEL DR should be taken with food. Talk to your doctor to ensure that you fully understand which dosage form you have been prescribed. Medicines which reduce stomach acid [such as Proton Pump Inhibitors (PPIs) and H2 blockers] can affect the absorption of ACTONEL DR. Discuss with your doctor or pharmacist how and when to take these medications.
