The following sections explain in detail the potentially negative interactions that can occur when Symbicort is combined with any of the drugs listed above.
Taking Symbicort and a beta blocker together can decrease the effectiveness of both medications. In addition, people with asthma should generally avoid beta blockers, as they may make their condition worse. While some beta blockers are less likely than others to interact with Symbicort, all beta blockers can potentially cause problems.

Combining Symbicort with certain antibiotics or antifungals can increase the level of Symbicort in your blood, potentially increasing your risk of side effects. Be sure to talk with your healthcare provider before taking Symbicort with an antibiotic or antifungal medication.
