For your allergic cold symptoms, over-the-counter second-generation antihistamines like Cetirizine, Loratadine, or Fexofenadine are highly effective. They help relieve sneezing, a runny nose, and watery eyes, usually without causing drowsiness. If your nasal symptoms are particularly bothersome, a glucocorticoid nasal spray like Fluticasone can also provide great relief. Please remember to stay hydrated and rest. While these medications are widely available, it is always safest to consult a doctor to ensure they are suitable for you and won't interact with any other health conditions.
