It is not normal to experience drowsiness when taking cephalosporin. Drowsiness does not occur when cephalosporin antibiotics are taken in normal doses. If a patient has drowsiness when taking cephalosporin, it may be an allergic reaction. The patient took other drugs during the cold, which have a sedative and sleeping effect, such as taking aminoglycosides, which have the effect of making the patient sleepy and weak. If the patient has the problem of drowsiness when taking cephalosporin, he must pay attention to whether there is the application of other drugs. The patient himself has a cold and fever, which can also lead to peripheral tiredness and weakness with drowsiness. Patients are advised to observe changes in their condition first, and if they have problems with their blood pressure heart rate or breathing, they must visit the hospital for examination and treatment in a timely manner. Patients can drink more water while taking cephalosporin. If the symptoms of drowsiness are heavy, it is recommended that patients stop taking oral cephalosporin or other anti-cold medications.
