You will need to check with your doctor if alcohol can be consumed with the medication you are taking. In many cases a moderate consumption (around two units per day) is fine, and may even have beneficial effects on the heart. A “nightcap” may also help you get off to sleep more easily, but you must check with your doctor or pharmacist that this is ok for you.
Medication should not be taken with alcohol, and when building up the dose of a new medication alcohol should generally be avoided.
Keep in mind that alcohol can exacerbate any incontinence problems, and ‘long’ drinks, such as beers and lagers, tend to have a worse effect than ‘short’ drinks, such as spirits.
