Can I drink alcohol whilst on ADHD medication? 

In short, it is strongly advised not to drink alcohol while taking ADHD medication. Combining alcohol with stimulants or non-stimulant ADHD medications can lead to serious health risks, including physical, psychological, and behavioural issues. 

1. Cardiovascular risks 

Alcohol and stimulant medications can significantly increase stress on the heart. This combination raises the risk of cardiovascular toxicity, which may result in elevated blood pressure, heart arrhythmias, or even heart attack. 

2. Reduced blood flow to the brain 

Mixing alcohol with ADHD medication can reduce blood flow to the brain, which may impair cognitive function and negate the benefits of the medication. 

3. Increased risk of overdose 

Alcohol can mask the effects of stimulant medication, leading to unintentional overuse. This increases the likelihood of severe side effects, overdose, or sudden death. 

4. Impacts on behaviour and mental health 

The combination can lead to erratic behaviour, heightened anxiety, or mood swings, undermining emotional stability and mental well-being. 

• Avoid alcohol completely: For your safety, it is best to refrain from drinking alcohol while taking ADHD medication. 

• Follow medical advice: If you have specific questions or concerns, speak with your clinician, who can provide tailored guidance based on your health and treatment plan. 

The potential risks of combining alcohol and ADHD medication far outweigh any perceived benefits. Prioritising your health means avoiding alcohol to ensure your medication works effectively and safely. If you have further questions, please discuss them during your next scheduled appointment.
