Alcohol and depression: what to know

Using alcohol to cope may also create a cycle: low mood prompts drinking, and the after-effects of drinking make mood, energy and daily functioning harder to manage.

Alcohol slows brain activity and can reduce inhibitions. As its effects wear off, some people notice lower mood, anxiety, irritability, poor concentration or fatigue. Drinking may make it easier to fall asleep initially, yet sleep is often lighter and more fragmented later in the night.

Depression can present with persistent sadness, loss of interest, hopelessness, altered sleep or appetite, and difficulty managing usual responsibilities. Alcohol can blur these symptoms and make it harder to judge whether treatment is helping. It may also increase drowsiness or other side effects from some medicines.

Tell your clinician honestly how often you drink, how much you tend to have, and whether alcohol changes your mood or behaviour. Keep a simple note of drinking, sleep, mood and medication doses; patterns can help guide a safer treatment plan.

Do not mix alcohol with antidepressants, sleeping tablets or anxiety medicines without checking with the prescriber or pharmacist. If you drink heavily or develop shaking, sweating, nausea, agitation or seizures when alcohol wears off, do not stop suddenly on your own; alcohol withdrawal can be dangerous and needs medical guidance.

Arrange a clinical appointment if low mood, loss of interest, sleep problems or drinking is affecting work, relationships, self-care or medication use. Seek urgent help if you are thinking about suicide or self-harm, feel unable to stay safe, become severely confused, have a seizure, or cannot wake normally after drinking. Contact local emergency services or go to the nearest emergency department, and stay with a trusted person if possible.

Ask whether alcohol could be contributing to your symptoms, whether it interacts with your medicines, and what support is suitable if cutting down feels difficult. You can also ask which withdrawal symptoms need immediate care and how your mood will be monitored while your drinking changes.
