For a cold and blocked nose, you can use safe over-the-counter options. To relieve congestion, a saline nasal spray is a great starting point. If needed, a decongestant nasal spray containing oxymetazoline can quickly clear your nose, but limit its use to three consecutive days to avoid worsening symptoms. Alternatively, an oral decongestant like pseudoephedrine can help. For general cold symptoms or body aches, paracetamol or ibuprofen is effective, while an antihistamine like cetirizine can ease a runny nose. Rest well and stay hydrated. If symptoms persist beyond ten days or worsen, please consult a healthcare professional for a personalised evaluation.
