Can You Take Ciprofloxacin with Alcohol?
Last reviewed: · Source: US FDA drug label database
Avoid alcohol with ciprofloxacin — it can increase side effects including dizziness, and alcohol impairs recovery from infection.
Is it safe to take Ciprofloxacin with Alcohol?
There is no severe direct pharmacological interaction between ciprofloxacin and alcohol, but combining them is not advisable. Alcohol can worsen common ciprofloxacin side effects including dizziness, confusion, and GI upset. Alcohol also impairs the immune system's ability to fight the infection being treated. Additionally, both ciprofloxacin and alcohol can lower the seizure threshold, which may be a concern for susceptible individuals.
How do Ciprofloxacin and Alcohol interact?
Ciprofloxacin inhibits bacterial DNA gyrase and is renally excreted with moderate hepatic metabolism. Alcohol does not significantly alter ciprofloxacin pharmacokinetics. However, alcohol can compound the CNS-related side effects (dizziness, headache, confusion) of ciprofloxacin, and both substances can lower the seizure threshold in predisposed individuals.

Frequently Asked Questions
Can I drink on ciprofloxacin?
Best avoided. Alcohol can worsen side effects like dizziness and GI upset, and it impairs your immune system when you need it most to fight infection.
Does ciprofloxacin react with alcohol like metronidazole?
No. Ciprofloxacin does not cause the severe disulfiram-like reaction that metronidazole does. The concerns with ciprofloxacin and alcohol are about worsened side effects and immune impairment.
Can ciprofloxacin and alcohol cause a seizure?
Both can independently lower the seizure threshold in predisposed individuals. The risk is low in people without a history of seizures, but it is a consideration.
How long after ciprofloxacin can I drink?
Ciprofloxacin has a half-life of 3-5 hours. After completing your course, waiting 24 hours before drinking is a sensible precaution.
