The combination of Paracetamol 125mg, Phenylephrine HCl 2.5mg, and Chlorpheniramine Maleate 1mg is commonly used to treat symptoms of the common cold, flu, or allergic rhinitis.

• Paracetamol (125mg) is an analgesic and antipyretic, helping to relieve pain and reduce fever associated with cold or flu.
• Phenylephrine HCl (2.5mg) is a decongestant that works by constricting blood vessels in the nasal passages, reducing swelling and congestion, and making it easier to breathe.
• Chlorpheniramine Maleate (1mg) is an antihistamine that helps reduce symptoms of allergy, such as sneezing, runny nose, and itching, by blocking histamine receptors in the body.

This combination is effective in relieving pain, congestion, and allergic symptoms, providing overall comfort during a cold or allergic reaction. However, it may cause drowsiness due to the antihistamine, so it should be used with caution when operating machinery or driving.
