I got a sick combo over the weekend, sore-throat + flu + cough. I hate sick and the taste of the medicine, they smell sucks >.< . Few flu medicines available at my house: Zyrtec-D, Zyrtec, Fedac , Telfast, Fenfedrin and today doctor gave me another one, Cetrizet-D. I feel so curious about all these drugs. Time to steal some knowledge from internet.

Here are the ingredients of each medicine:

  • Zyrtec          –  Cetirizine DiHydrochloride 10mg
  • Zyrtec D     – Cetirizine 2HCI 5mg, Pseudoephedrine HCI 120mg
  • Cetrizet D  – Cetirizine Hydrochloride 5mg, Pseudoephedrine Hydrochloride 120mg
  • Fedac            – Triprolidine HCI 2.5mg, Pseudoephedrine HCI 60mg
  • Telfast         –  Fexofenadine HCI 180mg
  • Fenfedrin  – Chlorpheniramine Maleate 4mg, Pseudoephedrine HCI 60mg

I found that all these flu medicines share some common ingredients:
– Second generation of drug to used in the treatment of hay fever, allergies & etc.
– Non-drowsy

– Pseudoephedrine is used to relieve nasal congestion caused by colds, allergies, and hay fever

– Triprolidine is a quick acting drug that can clear congestion and stop runny noses in 15-30 minutes
– Drowsiness

-Fexofenadine is used to relieve the allergy symptoms of seasonal allergic rhinitis (”hay fever”), including runny nose; sneezing; red, itchy, or watery eyes; or itching of the nose, throat.In a previous study, cetirizine and fexofenadine similarly relieved seasonal allergic rhinitis symptoms in the first 5 hours, but cetirizine was more effective at 21-24 hours postdose.

Chlorpheniramine Maleate
-Chlorpheniramine belongs to a group of medications known as first-generation antihistamines. It is used to treat symptoms caused by allergies, including itchy and watery eyes, sneezing, runny nose, and skin rash and irritations.
