Ontario Drug Benefit coverage
As of 31 July 2026General benefit Part III-A
Ontario lists this product as a general benefit under the Ontario Drug Benefit program — Part III-A of the Formulary/CDI. For someone eligible for ODB, it is covered without a drug-specific approval.
- What ODB pays per unit
- $0.9500
This is what the Ontario Drug Benefit program reimburses a pharmacy for one unit, as of 31 July 2026. A deductible and a co-payment sit on top of it and differ by program — ODB, the Trillium Drug Program and the seniors co-payment each work differently — so it is not the figure anyone is charged at a counter. It also says nothing about private, workplace or federal coverage.

Reported side effects
RxMonitor does not show reported side effects.
Health Canada collects voluntary reports of suspected side effects in the Canada Vigilance database. RxMonitor does not summarise them, because a count of reports is not a rate and the most-reported term for a medication is often the condition it is prescribed for — for a reliever inhaler, the most reported term is asthma. Nothing here should be read as a list of this medication’s side effects, or as evidence that it has few. The product monograph and a pharmacist are the sources for that.
How it is classified
