Lantus and Alcohol

by on April 18, 2012

It is generally recommended that patients using Lantus abstain from drinking alcohol, as drinking can cause hyperglycemia or hypoglycemia in patients that have insulin-dependent diabetes. Hypoglycemia is more likely to occur with the chronic drinking of large quantities of alcohol, and it can also occur after binge or moderate drinking, specifically when alcohol is consumed on an empty stomach.

With hypoglecemia, you may notice:

  • headaches
  • seizure
  • weakness / dowisiness
  • trembling / tremors
  • difficulty concentrating
  • rapid breathing and fast heartbeat
  • fainting

However, if alcohol use cannot be avoided, patients should try to drink moderately.  Moderate consumption of alcohol should not affect blood glucose levels as long as patients have well-controlled and monitored diabetes.   Moderate consumption may be defined as no more than 1-2 drinks per day.  A "drink" might be a single beer, or a glass of wine.  It is also recommend that the patient eat some food while drinking this small amount of alcohol.
