Calcium & Vitamin DConsider:
“caplets” or effervescent Rxs
Vit D alone (Fultium, Stexerol)
high dose Vit D

Why is compliance so poor?
• Osteoporosis is a silent condition• Patient`s beliefs/perception of fracture
risk• Actual side effects – GI, arthralgia• Fear of potential side effects• Memory impairment• Special requirements for dosing
“Take the medication 30-60 minutes before breakfast, On an empty stomach with a full
glass of plain tap water; Don`t take any other food, drink
or medications for at least half an hour;
• Remain upright and…….
Patients on oral bisphosphonates are instructed to:
Perforation of trabeculae

Osteoclast
Bone Surface Resorbed by Osteoclast
Osteonecrosis of the Jaw (ONJ)• < 1/100,000 pt yrs (in osteoporosis)• ↑ risk with iv bisphosphonates
poor oral hygienediabetescorticosteroidsmalignancy
• N.B. occurs with d`mab, thalidomide & antiVEGF injections and non-osteoporotics
• Dose-related (rather than duration- associated)
Dental check before and during Rx
AFFs - Typical Presentation• 0.3 - 1 /1,000 pt yrs • Minimal or no trauma• Noncomminuted• Prodromal thigh pain (64%)• Poor healing (25%)• Bilateral (70%)• >5 yrs bisphosphonate Rx• Assoc. with RA, steroids, PPIs, ↓ Vit D ,
higher BMDShane et al , JBMR 2014
AFFs - PREVENTION
• Appropriate Rx bisphos. (FRAX score)
(NB 2 atypical #s with denosumab)
• Teriparatide if high fracture risk
• “Drug holidays” for lower risk pts
Drug Holidays• Consider if fracture-free after 5yrs Rx• Review initial indication• Reassess current fracture risk (? T-score >-2.5)
NOT for pts with hip & vertebral #sv. low T-scores>75 yrs + >7.5 mg pred.
