In America and most countries, none do. In the US, codeine is a controlled substance that can only be administered by prescription.
Actually your answer is not correct. Cough syrup containing codeine can be purchased from a pharmacist and siging a log book. I am a Pharmacist and at least in Tennessee this is legal.
Tylenol is usually already in most OTC cough syrups, you'll want to watch how much you take as Tylenol is toxic in high doses and can seriously damage your liver, not to mention kill you. (4000mgs+)
A persistent cough lasts for over a week , with no response to cough syrups.
ANY cough medicine that contains alcohol.
Yes. Cough syrups mix medicinal chemicals and other substances to create the orally taken medicine.
Chloroform cannot be used in cough syrups. It is a known carcinogen (cancer causing agent) and has not been used in the field of medicine for many decades.
most of d syrups contain dextromethorphan(cough suppressant), cetirizine(antihistaminic to reduce allergy) and guafenecin(works by thinning the cough).... syrup is used so that this combination gets absorbed rapidly and properly in your system.... :-)
so people get drunk
codeine and promethazine
If a cough syrup has alcohol as an ingredient, then it contain a stimulant, There are some cough syrups without alcohol.
There is a synthetic narcotic called 'dextromethorphan' which is found in cough syrups, but not tylenol. In older cough medicines, and tylenol, there was a narcotic by the name of 'codeine'. Hope I helped.
