Concor Cor can be used with medicines you are constantly taking if it has been prescribed by the same doctor, or if the prescriber has been told what other medicines you are already taking and what additional medical conditions you are suffering from. Combining these medicines increases the risk of side effects such as excessive lowering of blood pressure, headache and dizziness. These actions may occur especially at the beginning of the implementation of treatment. In addition, bisoprolol (the active ingredient in Concor Cor) can sometimes cause bronchospasm, which may worsen asthma symptoms and require adjustment of asthma treatment. If you have any alarming symptoms after taking Concor Cor, consult your doctor.
