Table of contents:

Buckley's Mixture is a cough syrup that is commonly used to treat coughs caused by the common cold or flu. It is noted for its unpleasant taste and strong medicinal odor. Buckleys Mixture will not treat a cough caused by smoking, asthma, or emphysema.

The active ingredient in Buckley's Mixture is dextromethorphan, which is a cough suppressant that acts on the brain to reduce the urge to cough. It also contains other ingredients such as menthol, camphor, and potassium bicarbonate, which help to soothe the throat and alleviate congestion.

Use and Dosage

Take Buckleys Mixture Syrup by mouth, according to your doctor's instructions, usually every 4 to 12 hours as needed. If you experience stomach upset, take it with food or milk. Use a medication-measuring device to ensure accurate dosing of liquid medication. Do not use a household spoon, as it may lead to an incorrect dose. Gently shake the suspension before measuring out your dose.

The dosage of Mixture Syrup depends on your age, medical condition, and response to treatment. If you are taking it for self-treatment without a prescription from your doctor, follow the dosing instructions on the packaging to determine the proper dose for your age.

Take Mixture Syrup regularly at around the same time every day if your doctor has instructed you to take it daily. This will help you get the most benefit from it and remember to take it.

Improper use of Mixture Syrup may lead to severe harm, such as brain damage, seizure, or death. Do not exceed the prescribed dose, take it more often than recommended, or use it for a longer period than directed. Discontinue use as directed by your physician.

Contact your doctor if your symptoms persist or worsen after more than a week, or if you experience fever, chills, headache, or rash, as they may indicate a more serious condition.
