Medication details

Benylin Dry Cough Syrups are specially formulated medications aimed at alleviating the discomfort associated with dry coughs. Unlike productive coughs that bring up mucus, dry coughs do not produce phlegm or mucus, making them particularly bothersome. Benylin Dry Cough Syrups are available in various formulations to suit different preferences, including sugar-free options and those suitable for both adults and children.

Proper usage of Benylin Dry Cough Syrups is crucial for both effectiveness and safety. Here are the recommended directions for use:
Adults and Children over 12 Years:
Take one or two 5 ml spoonfuls (one 5 ml spoonful is equivalent to one dose).
Repeat the dose every 4 to 6 hours as needed.
Do not exceed four doses (20 ml) in 24 hours.
Children Aged 6 to 12 Years:
Take one 5 ml spoonful (one dose).
Repeat the dose every 4 to 6 hours as needed.
Do not exceed four doses (20 ml) in 24 hours.
Children Aged 1 to 5 Years:
Give half a 5 ml spoonful (half a dose).
Repeat the dose every 4 to 6 hours as needed.
Do not exceed four doses (10 ml) in 24 hours.
Do Not Use in Children Under 1 Year of Age.
Always use the provided measuring spoon or cup to ensure accurate dosing.


Understanding the active and inactive ingredients in Benylin Dry Cough Syrups is essential for safe and effective use.
Active Ingredients:
Dextromethorphan: Dextromethorphan is an antitussive, meaning it works to suppress the cough reflex in the brain. It helps reduce the frequency and intensity of dry coughing.
Inactive Ingredients: Benylin Dry Cough Syrups may contain various inactive ingredients, such as sucrose, sorbitol, glycerol, sodium benzoate, and various flavorings. Be sure to check the product label for a complete list of inactive ingredients, especially if you have allergies or sensitivities.

Side Effects

While Benylin Dry Cough Syrups are generally well-tolerated when used as directed, some individuals may experience side effects. Common side effects may include:
Dizziness: Some individuals may experience mild dizziness while taking Benylin Dry Cough Syrups.
Nausea or Upset Stomach: In rare cases, individuals may experience mild gastrointestinal discomfort.
Allergic Reactions: Allergic reactions to the active or inactive ingredients are possible, although they are relatively rare. If you experience symptoms such as skin rash, itching, swelling, severe dizziness, or difficulty breathing, seek medical attention immediately.
If you encounter severe or persistent side effects or experience any unusual reactions, discontinue use and consult a healthcare professional. It's essential to discuss any concerns about side effects or interactions with other medications with your healthcare provider.


Before using Benylin Dry Cough Syrups, consider the following warnings and precautions:
Allergies: If you have known allergies to any of the active or inactive ingredients in Benylin Dry Cough Syrups, do not use this medication. Allergic reactions can range from mild skin rashes to severe anaphylaxis, a potentially life-threatening condition.
Underlying Medical Conditions: If you have certain underlying medical conditions, such as liver or kidney disease, consult with a healthcare professional before using Benylin Dry Cough Syrups. These conditions may necessitate special considerations or adjustments in dosage.
Monoamine Oxidase Inhibitors (MAOIs): Do not use Benylin Dry Cough Syrups if you are taking or have taken MAOIs within the last 14 days, as serious interactions may occur.
Pregnancy and Breastfeeding: If you are pregnant or breastfeeding, consult with a healthcare professional before using Benylin Dry Cough Syrups. They can provide guidance on the safety of the medication during pregnancy or while nursing.
Alcohol: Avoid consuming alcohol while taking Benylin Dry Cough Syrups. Alcohol can potentiate the sedative effects of the medication and may lead to drowsiness and impaired coordination.
Driving and Machinery: Due to the potential for drowsiness, refrain from driving or operating heavy machinery until you are aware of how Benylin Dry Cough Syrups affect you.
