The recommended dose in adults is one 35 mg tablet orally once a week. The tablet should be taken on the same day each week. The absorption of risedronate sodium is affected by food, thus to ensure adequate absorption, patients should take Risedronate sodium 35 mg: • Before breakfast: At least 30 minutes before the first food, other medicinal product or drink (other than plain water), of the day.
Patients should be instructed that if a dose is missed, one Risedronate sodium 35 mg tablet should be taken on the day that the tablet is remembered. Patients should then return to taking one tablet once a week on the day the tablet is normally taken.
Two tablets should not be taken on the same day. The tablet must be swallowed whole and not sucked or chewed. To aid delivery of the tablet to the stomach Risedronate sodium is to be taken while in an upright position with a glass of plain water (≥ 120 ml).
4). Supplemental calcium and vitamin D should be considered if the dietary intake is inadequate. The optimal duration of bisphosphonate treatment for osteoporosis has not been established. The need for continued treatment should be re-evaluated periodically based on the benefits and potential risks of Risedronate sodium on an individual patient basis, particularly after 5 or more years of use.
Special populations Elderly:
No dosage adjustment is necessary since bioavailability, distribution and elimination were similar in elderly (> 60 years of age) compared to younger subjects. This has also been shown in the very elderly, 75 years old and above postmenopausal population.
Renal impairment:
No dosage adjustment is required for those patients with mild to moderate renal impairment. 2). 1).
Risedronate sodium has been studied in phase III clinical trials involving more than 15,000 patients. The majority of undesirable effects observed in clinical trials were mild to moderate in severity and usually did not require cessation of therapy.
Adverse experiences reported in phase III clinical trials in postmenopausal women with osteoporosis treated for up to 36 months with risedronate sodium 5 mg/day (n=5020) or placebo (n=5048) and considered possibly or probably related to risedronate sodium are listed below using the following convention (incidences versus placebo are shown in brackets): Very common (≥1/10), Common (≥1/100 to <1/10), Uncommon (≥1/1,000 to <1/100), Rare (≥1/10,000 to <1/1,000), Very rare (<1/10,000), Not known (cannot be estimated from the available data).

The following additional adverse reactions have been reported during post- marketing use: Immune system disorders Not known: Anaphylactic reaction.
Eye disorders Not known:
Iritis, uveitis.
Hepatobiliary disorders Not known:
Serious hepatic disorders. In most of the reported cases the patients were also treated with other products known to cause hepatic disorders.
5). 5 SD) and/or prevalent fracture. High age or clinical risk factors for fracture alone are not reasons to initiate treatment of osteoporosis with a bisphosphonate. 1). Bisphosphonates have been associated with oesophagitis, gastritis, oesophageal ulcerations and gastroduodenal ulcerations.
g. stricture or achalasia • In patients who are unable to stay in the upright position for at least 30 minutes after taking the tablet. • If risedronate sodium is given to patients with active or recent oesophageal or upper gastrointestinal problems (including known Barrett‘s oesophagus)..
Prescribers should emphasise to patients the importance of paying attention to the dosing instructions and be alert to any signs and symptoms of possible oesophageal reaction. The patients should be instructed to seek timely medical attention if they develop symptoms of oesophageal irritation such as dysphagia, pain on swallowing, retrosternal pain or new/worsened heartburn.
Hypocalcaemia should be treated before starting risedronate sodium therapy. g. parathyroid dysfunction, hypovitaminosis D) should be treated at the time of starting risedronate sodium therapy. Osteonecrosis of the jaw, generally associated with tooth extraction and/or local infection (including osteomyelitis) has been reported in patients with cancer receiving treatment regimens including primarily intravenously administered bisphophonates.
Many of these patients were also receiving chemotherapy and corticosteroids. Osteonecrosis of the jaw has also been reported in patients with osteoporosis receiving oral bisphosphonates. g. cancer, chemotherapy, radiotherapy, corticosteroids, poor oral hygiene).
While on treatment, these patients should avoid invasive dental procedures if possible. For patients who develop osteonecrosis of the jaw while on bisphosphonate therapy, dental surgery may exacerbate the condition. For patients requiring dental procedures, there are no data available to suggest whether discontinuation of bisphosphonate treatment reduces the risk of osteonecrosis of the jaw.

Ear and labyrinth disorders Very rare:
Osteonecrosis of the external auditory canal (bisphosphonate class adverse reaction)
Clinical judgment of the treating physician should guide the management plan of each patient based on individual benefit/risk assessment. Osteonecrosis of the external auditory canal has been reported with bisphosphonates, mainly in association with long-term therapy.
Possible risk factors for osteonecrosis of the external auditory canal include steroid use and chemotherapy and/or local risk factors such as infection or trauma. The possibility of osteonecrosis of the external auditory canal should be considered in patients receiving bisphosphonates who present with ear symptoms including chronic ear infections.
Atypical fractures of the femur Atypical subtrochanteric and diaphyseal femoral fractures have been reported with bisphosphonate therapy, primarily in patients receiving long-term treatment for osteoporosis. These transverse or short oblique, fractures can occur anywhere along the femur from just below the lesser trochanter to just above the supracondylar flare.
These fractures occur after minimal or no trauma and some patients experience thigh or groin pain, often associated with imaging features of stress fractures, weeks to months before presenting with a completed femoral fracture. Fractures are often bilateral; therefore the contralateral femur should be examined in bisphosphonate-treated patients who have sustained a femoral shaft fracture.
Poor healing of these fractures has also been reported. Discontinuation of bisphosphonate therapy in patients suspected to have an atypical femur fracture should be considered pending evaluation of the patient, based on an individual benefit risk assessment.
During bisphosphonate treatment patients should be advised to report any thigh, hip or groin pain and any patient presenting with such symptoms should be evaluated for an incomplete femur fracture.
