• Dry Cough: Look for syrups containing dextromethorphan or diphenhydramine, which are effective at suppressing dry, non-productive coughs.
• Productive Cough: Guaifenesin is the key ingredient to look for if you’re dealing with a productive cough, as it helps thin mucus, making it easier to clear from your airways.

• Honey: Known for its soothing properties, honey can help calm a sore throat and reduce coughing.

3. Age Restrictions

Some cough syrups are suitable for children, while others are formulated only for adults. Be sure to check the recommended age range and follow dosage guidelines carefully, especially for young children.

4. Sugar-Free or Alcohol-Free Options

If you’re watching your sugar intake or need an alcohol-free product, look for sugar-free or alcohol-free versions of cough syrup. These formulations are available in both dry and productive cough types.

5. Additional Benefits
