Why is this medication prescribed?

Dex-Tuss is typically prescribed to relieve coughing caused by minor throat and bronchial irritation due to the common cold, flu, or other respiratory tract infections. It contains two active ingredients:

  • Codeine: This is an opioid cough suppressant that works in the brain to help decrease the urge to cough.
  • Guaifenesin: This is an expectorant that helps to thin and loosen mucus in the airways, making it easier to cough up and clear the air passages.

How should this medicine be used?

Dex-Tuss should be used exactly as prescribed by your healthcare provider or as directed on the medication label. Here’s a general guideline for using Dex-Tuss:

  • Dosage: Take the medication exactly as prescribed by your doctor. The dosage may vary depending on your age, weight, medical condition, and response to treatment. Do not take more than the recommended dose or take it more frequently than prescribed.
  • Administration: Dex-Tuss is usually taken orally with a full glass of water. You can take it with or without food. Shake the liquid form of the medication well before measuring a dose. Use a proper measuring device, such as a medication spoon or cup, to ensure accurate dosage.
  • Frequency: Take Dex-Tuss as needed for cough relief, typically every 4 to 6 hours. Do not exceed the recommended dosage or frequency of administration unless instructed by your doctor.
  • Duration: Use Dex-Tuss for the shortest duration necessary to relieve your symptoms. Do not use it for longer than recommended without consulting your healthcare provider.
  • Avoid Alcohol: Avoid consuming alcoholic beverages while taking Dex-Tuss, as alcohol can increase the risk of side effects, including dizziness, drowsiness, and difficulty breathing.
  • Storage: Store Dex-Tuss at room temperature away from moisture and heat. Keep it out of reach of children and pets.
  • Follow-up: If your symptoms persist or worsen despite using Dex-Tuss, or if you experience any concerning side effects, contact your healthcare provider for further evaluation and guidance.

Remember, Dex-Tuss contains codeine, which is an opioid medication. It should be used cautiously and only as prescribed due to the potential for misuse, addiction, and serious side effects. Be sure to discuss any concerns or questions about Dex-Tuss with your doctor or pharmacist.
