Pharmacists today warned Christmas revellers against taking alcohol while on medication or herbal supplements.
The Irish Pharmaceutical Union urged people to enjoy the festive spirit without putting their health, personal safety or the safety of others at risk.

IPU vice-president Liz Hoctor said women in particular may become drowsy or sedated by consuming alcohol with medicine.
"Women are particularly at risk of complications caused by consuming alcohol in addition to medication," said the Mullingar pharmacist. "A cocktail of alcohol and such remedies can result in marked sedation which can impair judgement and personal safety.
"Herbal remedies, which use Echinacea, Camomile and Valerian, which are especially popular with women, can lead to marked sedation and drowsiness when combined with alcohol. "These side affects can reduce levels of personal safety when on a night out."
The IPU pointed out that there was a high demand for common cold remedies and herbal supplements in December. "It is important to consult your pharmacist when buying any medication and this is especially important at this time of year," added Ms Hoctor.
"Taking alcohol without knowing how it will affect your medication or supplements can lead to people unintentionally putting their safety and the safety of others at risk."
The IPU encouraged people to speak to their local pharmacist if they have a concern about the effects of consuming alcohol with any form of medication.
