Outcome Measures

Primary Outcomes (1)

  • Recurrence frequency of benign paroxysmal positional vertigo

    The intervention group will receive tablets containing 400IU cholecalciferol and 500mg of elemental calcium as calcium carbonate twice daily (CAVID CHEWABLE TAB, Takeda Pharmaceuticals) for 12 months when the initial serum vitamin D is decreased. The compliance will be determined by the percentage of consumed tablets from the delivered tablets during the follow-up period. Discontinuation of the supplementation due to adverse effects or other reasons will be registered using the telephone interview together with the primary outcome date. Participants in the control group will not have any intervention or placebo. They will not be allowed to take vitamin D or calcium as supplements during the follow-up. The primary outcome measure is the recurrence of BPPV after one year. Data on recurrences will be collected using a monthly telephone interview, and the patients will be asked to visit the clinic whenever they have the symptoms of BPPV. All the recurrences of BPPV will be included.

    Up to 1 year

Secondary Outcomes (5)

  • Changes in serum 25-hydroxy vitamin D level

    Up to 1 year

  • Falling frequency

    Up to year

  • Fracture frequency

    Up to 1 year

  • Quality of life

    Up to 1 year

  • Recurrence rate of benign paroxysmal positional vertigo

    Up to 1 year

Study Arms (2)

Vitamin D and calcium supplement

ACTIVE COMPARATOR
Drug: 400IU cholecalciferol and 500mg of elemental calcium as calcium carbonate

Control

NO INTERVENTION

Interventions

The patients allocated to the intervention group will have a test for serum vitamin D, and receive 800 IU of vitamin D and 1000 mg of calcium as calcium carbonate when the serum vitamin D is decreased. The patients in the control group will be followed up without intervention for one year.
