1. Effect on Cold Symptoms:

   • Alerid syrup (cetirizine) is an antihistamine that may help with allergy-like symptoms such as a runny nose or sneezing.
   • It does not treat the viral infection causing a cold.

2. Cold Duration:

   • Viral infections typically last about a week. Continue supportive care like rest and hydration.

3. Additional Measures:

   • Consider decongestants, pain relievers, or throat lozenges for symptom relief.
   • Consult a healthcare provider before combining medications.

4. When to Seek Medical Advice:

   • If symptoms worsen, persist beyond 10 days, or you develop high fever, difficulty breathing, or chest pain, seek medical attention.

Summary: Alerid can help with some symptoms but is not a cure for the cold. Focus on supportive care and monitor your symptoms.
