You can take cough syrups containing Dextromethorphan and Phenylephrine for control of cough and congestion if it is Chat Doctor.  However, if you are suffering from severe hypertension, you should not take this syrup. If you have hypertension, you can take medicine containing only Dextromethorphan such as Alex cough lozenges. If you are suffering from cough with a lot of sputum, Then you can take cough syrups containing Ammonium chloride Cetirizine and Phenylephrine which help to bring out the sputum.
