While you want quick relief, it is generally not recommended to take Augmentin (amoxicillin/clavulanate) and levofloxacin together without direct supervision from your doctor. Combining these two strong antibiotics can increase the risk of side effects, such as severe stomach upset. Sometimes, one of these antibiotics can actually treat both infections, or they may need to be carefully spaced out. Please contact your doctor or dentist to confirm the safest way to take your medication.
