Oral bisphosphonates are absorbed very poorly; therefore counselling should be given to the patient as to how and when administration is most appropriate.
All oral bisphosphonate should be taken in combination with calcium & vitamin D (see section 9.6 Vitamins), the patient should be offered the product they like the best to achieve concordance.
Patient information leaflet: Your osteoporosis medication explained
Prescribers are reminded to check that an annual infusion of zoledronic acid has not been given, prior to commencing oral bisphosphonates.
Please refer to formulary guidance: Management of osteoporosis
MHRA Drug Safety Update (Nov 2009): The risk of developing osteonecrosis of the jaw with oral bisphosphonates seems to be low. The risk of is substantially greater for patients receiving I/V bisphosphonates for cancer indications than for patients receiving oral bisphosphonates for osteoporosis of Paget's disease. To minimise risk all patients should have a dental check-up before bisphosphonate treatment. All other patients who start bisphosphonates should have a dental examination only if they have poor dental status. During treatment, patients should maintain good oral hygiene, receive routine dental check-ups, and report any oral symptoms such as dental mobility, pain, or swelling.
MHRA Drug Safety Update (June 2011): Atypical femoral fractures have been reported rarely with bisphosphonate therapy, mainly in patients receiving long-term treatment for osteoporosis. They are often bilateral; therefore the contralateral femur should be examined in patients who have sustained a femoral shaft fracture. Discontinuation of therapy in patients suspected to have an atypical femur fracture should be considered while they are evaluated, and should be based on an assessment of the benefits and risks of treatment for the individual. During treatment, patients should be advised to report any thigh, hip, or groin pain. Any patient who presents with such symptoms should be evaluated for an incomplete femur fracture. The optimum duration of 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 bisphosphonate therapy for individual patients, particularly after 5 or more years of use.

- Pre-existing hypocalcaemia must be corrected prior to initiating denosumab, and supplementation of calcium and vitamin D is required in all patients receiving 120mg denosumab unless hypercalcaemia is present.
- Adequate intake of calcium and vitamin D is important in all patients receiving 60mg denosumab
- MHRA Drug Safety Update (Oct 2012) The following precautions should be followed to minimise the risk of hypocalcaemia with denosumab:
- Denosumab 120mg (for cancer indications) should not be used in patients with severe, untreated hypocalcaemia
- Denosumab 60mg (for osteoporosis indications) should not be used in patients with hypocalcaemia, regardless of severity (the contraindications vary between the two doses, because their indications are different).
- Patients with severe renal impairment (creatinine clearance less than 30mL; eGFR 15 – 29 mL/min/1.73m2) or receiving dialysis are at greater risk of developing hypocalcaemia, and monitoring of calcium levels in these patients is recommended.
- NICE TA204: Denosumab for the prevention of osteoporotic fractures in postmenopausal women (October 2010)
- NICE TA265: Denosumab for the prevention of skeletal-related events in adults with bone metastases from solid tumours (October 2012)
- MHRA Drug Safety Update (Feb 2013) Atypical femoral fractures have been reported rarely in patients with postmenopausal osteoporosis receiving long-term (2.5 years or longer) treatment with denosumab 60mg in a clinical trial. During denosumab treatment, patients presenting with new or unusual thigh, hip or groin pain should be evaluated for an incomplete femoral fracture. Discontinuation of denosumab therapy should be considered if an atypical femur fracture is suspected, while the patient is evaluated.
- MHRA Drug Safety Update July 2015 and MHRA Drug Safety Update June 2017:
- Before prescribing denosumab or intravenous bisphosphonates:
- give patients the patient reminder card for their medicine
- explain the risk of osteonecrosis of the jaw, and osteonecrosis of the external auditory canal, and advise patients on precautions to take
- do not prescribe denosumab 120mg (cancer indication) to patients with unhealed lesions from dental or oral surgery
- advise patients to report any problems with their mouth or teeth, any ear pain, discharge from the ear, or an ear infection during denosumab treatment
- please continue to report suspected side effects to denosumab, bisphosphonates or any other medicines on a Yellow Card.
Bone formation stimulants
- Severe postmenopausal osteoporosis in women at high risk of fracture
- Severe osteoporosis in men at increased risk of fracture
- 2g once daily in water, preferably at bedtime
- Strontium ranelate is being discontinued at the end of August 2017, patients currently taking this medication will require a review and a fracture risk assessment.
- Use of strontium ranelate is now restricted to treatment of severe osteoporosis: i) in postmenopausal women at high risk of fracture; ii) in men at increased risk of fracture (see MHRA warning below).
- MHRA Drug Safety Update (April 2013)- Strontium ranelate (Protelos): risk of serious cardiac disorders—restricted indications, new contraindications, and warnings
- Treatment should only be initiated by a physician with experience in the treatment of osteoporosis, and the decision to prescribe strontium ranelate should be based on an assessment of the individual patient's overall risks
- Strontium ranelate should not be used in patients with: ischaemic heart disease, peripheral arterial disease; cerebrovascular disease; a history of these conditions; or in patients with uncontrolled hypertension
- Prescribers are advised to assess the patient's risk of developing cardiovascular disease before starting treatment and thereafter at regular intervals
- Patients with significant risk factors for cardiovascular events (e.g. hypertension, hyperlipidaemia, diabetes mellitus, smoking) should only be treated with strontium ranelate after careful consideration
- Treatment should be stopped if the patient develops ischaemic heart disease, peripheral arterial disease, cerebrovascular disease, or if hypertension is uncontrolled
- Healthcare professionals should review patients at a routine appointment and consider whether or not to continue treatment
- Strontium should be taken in-between meals, preferably at bedtime at least two hours after food, milk products or calcium supplements. Ensure patients can comply with this regimen.
- Strontium should not be used in patients with severe renal impairment (creatinine clearance less than 30mL/min).
- Laboratory measurements of serum calcium are unreliable for patients taking strontium.
- Reductions in vertebral and non-vertebral fractures have been demonstrated but reductions in hip fracture only apparent in those aged over 74 years with T score of -2.4SD.
- Strontium reduces the absorption of tetracyclines and quinolones: therapy should be suspended for the duration of the antibiotic course.
- Strontium should not be used during pregnancy or lactation.
- Severe hypersensitivity syndromes including drug rash with eosinophilia and systemic symptoms (DRESS) has been reported with strontium.
