Citalopram and Alcohol
One general rule in medicine is to limit alcohol consumption while under treatment, especially for drugs such as Citalopram (Celexa) that affect the nervous system.
Studies have demonstrated that both alcohol and citalopram affects similar chemicals inside the brain. When used in combination the sedative effects of alcohol may be increased and you may experience a severe impairment of your motor skills and judgement.
Drinking alcohol in excess while on Citalopram is strongly not recommended. If blackouts or unconsciousness occur you should contact an emergency room.
If Alcohol consumption is unavoidable while taking Citalopram, your doctor would advise you to only drink in very small or moderate amounts. In this case, a small amount would be considered as a single beer or a single glass of wine.
