New figures from the Central Statistics Office show that consumer prices posted an annual fall of 1.1% in November.
The CSO said this compared to a fall of 1.5% in October, when consumer prices saw their sharpest fall for a decade.
Consumer prices have dropped on an annual basis for eight months in a row since Covid-19 restrictions were first introduced in March.
But consumer prices rose by 0.3% in November from October to register the first price growth since June, the CSO added.
Today's figures show that clothing and footwear costs - on an annual basis - fell by 7.9% due to sales.
Transport costs were down 3% due to a reduction in air fares and lower prices for diesel and petrol, which were partially offset by higher prices for cars.
November also saw lower home heating oil and natural gas prices as well as lower rents, but the cost of electricity rose while consumers also saw higher mortgage interest repayments.
Today's figures show that health costs rose in November rose mainly due to an increase in the cost of medical and dental services.
Last month also saw higher health insurance premiums and higher prices for hairdressers, but these increases were partially offset by lower car insurance premiums and a fall in the price of other personal effects
