What would happen if I drunk alcohol after getting a penicillin shot?

Drinking alcohol after receiving a penicillin shot is generally not harmful, as there are no major interactions between the two. However, alcohol can impair your immune system and may hinder your body’s ability to recover from the infection being treated. Additionally, it might increase the risk of side effects, such as nausea or dizziness, depending on individual tolerance. It's always best to consult your healthcare provider for personalized advice.
