Intunal used to treat flu symptoms

Table of Contents

Intunal Forte is an over-the-counter tablet medicine for relieving flu symptoms, including fever, headache, nasal congestion, and sneezing with coughing.

Intunal Forte tablets contain Paracetamol (Acetaminophen), Dexchlorpheniramine maleate (CTM), Guaifenesin or Glyceryl Guaiacolate (GG), Dextromethorphan HBr, and Phenylpropanolamine.

Ingredients of Intunal

Each Intunal Forte tablet contains:

  • 50 mg of Paracetamol (Acetaminophen), which is an active substance that works to reduce fever and relieve pain that you can get without a doctor’s prescription.
  • 2 mg of Dexchlorpheniramine maleate (CTM), which is an active substance to treat allergic symptoms, such as rhinitis and urticaria. This substance belongs to the first generation of antihistamines with a low sedative effect.
  • 50 mg of Guaifenesin or Glyceryl Guaiacolate (GG), which is a medicine that works by increasing the volume and reducing the viscosity of mucus in the trachea and bronchi–making the phlegm easier to cough out.
  • 15 mg of Dextromethorphan HBr, which is an active substance that can be used for suppressing cough–especially coughs triggered by mild throat and bronchial irritations. It is in the morphinan class of medications with sedative, dissociative, and stimulant properties.
  • 15 mg of Phenylpropanolamine, which is an active substance that functions as a stimulant and nasal decongestant. This substance helps treat cold symptoms and nasal congestion.

What is Intunal Used for 

Influenza is a viral infection that attacks your respiratory system. It is known as the flu, but it is not the same as the stomach flu viruses that cause diarrhea and vomiting.

At first, the flu may be characterized by a runny nose, sneezing, and sore throat. However, cold symptoms usually develop gradually, whereas the flu symptoms tend to appear suddenly. Cold may be irritating enough, but the flu may make your condition feel worse. 

Intunal can be used to provide relief for flu symptoms, including:

  • Fever
  • Headache
  • Nasal congestion
  • Sneezing and coughing
