Is phenergan dm cough syrup like codeine cough syrup?

Phenergan DM cough syrup and codeine cough syrup serve similar purposes in alleviating cough symptoms, but they differ significantly in their ingredients and effects. Phenergan DM contains the antihistamine promethazine and the cough suppressant dextromethorphan, while codeine cough syrup includes the opioid codeine as its active ingredient. Codeine is a narcotic and can be more effective for severe cough due to its pain-relieving properties but also carries a higher risk of dependence and side effects. Always consult a healthcare professional before using either medication.
