Mixing Alcohol and Lithium
Because lithium and alcohol both affect the central nervous system, understanding the potential effects of drinking alcohol and taking lithium is important. Mixing these two substances has its own side effects, impacts your mental health and dehydrates the body. It is important to take all of these factors into account before drinking.

Lithium and Alcohol Side Effects
Because alcohol and lithium both affect the central nervous system, taking them together can increase side effects. Some of the side effects that can be amplified by combining alcohol and lithium include:

- Coordination problems
What Are the Risks of Drinking Alcohol on Lithium?
The risks of drinking on lithium involve your health and your mental status. Besides the potential for worsened side effects when you combine lithium and alcohol, drinking may also exacerbate your bipolar disorder and can lead to dehydration. Dehydration, in turn, can cause your lithium levels to increase dangerously.
Alcohol, Lithium and Dehydration
An important consideration to keep in mind about alcohol and lithium is that drinking alcohol can be dehydrating. This can cause the amount of lithium in your blood to rise, which can become toxic.
Even when you’re not planning to combine alcohol and lithium, you should stay hydrated throughout the day to avoid dehydration. Further, people on lithium are advised to maintain a balanced diet, which can be interrupted by heavy drinking.
Alcohol and Bipolar Disorder
When you suffer from bipolar depression, alcohol can make your symptoms worse, regardless of whether or not you’re on lithium. Alcohol is a depressant, so it may not be advisable for someone with bipolar disorder to drink, particularly not excessively.

Taking Lithium After Alcohol
You should always take your lithium exactly as prescribed and when the dose is scheduled to be taken. Because lithium can last for hours in your body and is intended to be dosed around the clock to stabilize your mood, it is unclear what the safest time to take lithium after drinking is.
Drinking After Taking Lithium
Because lithium is dosed multiple times a day to keep a stable level of the drug in your body and control your mood, it is unclear if there is a safe window for drinking after you have taken a dose of lithium.
Can You Overdose on Alcohol & Lithium?
Becoming dehydrated from vomiting or urinating after drinking can cause the lithium levels in your blood to increase to toxic levels. Your doctor likely keeps a close eye on your lithium levels for this reason. It is important to remain well-hydrated while on lithium and to replace any fluids you lose from vomiting or excessive urination after drinking. Symptoms of lithium toxicity include:
- Gait problems
- Muscle weakness
Drug overdose can be fatal. If you suspect someone is experiencing an overdose, call 911 immediately. Do NOT be afraid to seek help. If you do not have access to a phone contact Web Poison Control Services for online assistance.
