Are you Looking to Buy (Guaifenesin - non Rx) from OnlineCanadianPharmacy.

Formulation : Extended Release 12Hour Tablet
Dosage : 600mg
Quantity : 20
Prescription Prescription Not Required
(All Prices in USD)


  • Medication used for temporary relief of coughs from common cold, bronchitis, and other breathing illnesses
  • Not recommended for ongoing cough from smoking or long-term breathing problems without doctor’s direction
  • Guaifenesin is an expectorant that thins and loosens mucus, clearing congestion and easing breathing


Dosage and administration

  • Take the medication by mouth with or without food, as directed by the doctor, usually every 12 hours with a full glass of water
  • If self-treating, follow all directions on the product package; consult doctor or pharmacist for questions
  • Dosage based on age, medical condition, and treatment response; do not exceed 2400 milligrams in 24 hours
  • Do not crush or chew tablets; swallow them whole to avoid releasing the drug at once and increasing side effect risk
  • Drink plenty of fluids to help break up mucus and clear congestion
  • Notify the doctor if the condition returns, or if accompanied by persistent headache, fever, severe sore throat, rash, or worsening after 7 days
  • Seek medical help immediately if there’s suspicion of a serious medical problem


Side effects

  • Possible side effects include nausea or vomiting; inform doctor or pharmacist if they persist or worsen
  • If directed by the doctor to use the medication, the benefits are deemed greater than the risk of side effects
  • Serious allergic reactions are rare; seek immediate medical help for symptoms like rash, swelling, severe dizziness, or difficulty breathing
  • Not an exhaustive list of side effects; contact doctor or pharmacist for other observed effects



  • Inform your doctor or pharmacist about any allergies to guaifenesin or other substances before taking it
  • Check with your pharmacist about inactive ingredients in the product that may cause allergic reactions
  • Share your medical history, especially breathing problems like emphysema, chronic bronchitis, asthma, or cough with blood or large amounts of mucus, with your doctor or pharmacist before using the medication
  • Before surgery, inform your doctor or dentist about all products you use, including prescription drugs, nonprescription drugs, and herbal products
  • Use guaifenesin during pregnancy only if clearly needed; discuss risks and benefits with your doctor
  • Consult your doctor before breastfeeding, as it is unknown if guaifenesin passes into breast milk
