I start augmentin (amoxicillin and clavulanate) tomorrow can i have sex tonight and when im taking the augmentin (amoxicillin and clavulanate)?

Why tomorrow?: Why start Augmentin (amoxicillin and clavulanate) tomorrow? If you're sick, start it now. Don't delay. With that said, Augmentin (amoxicillin and clavulanate) & other antibiotics won't prevent you from having sex although illness that led to need for antibiotics might not make you feel like having sex. Bottom line, if you wanna do it, have fun! but don't feel like you have to do so.

Contraindication: Sex is not one of the contraindications of augmentin (amoxicillin and clavulanate). Sex is only a problem when std s are treated (reinfection risk). Do not worry if that is not the case.
