Frequent nasal and throat infections require a proper medical evaluation rather than self-medication. These recurrent episodes can be caused by viral infections, allergies, environmental irritants, or structural issues like a deviated septum. I strongly advise against taking over-the-counter antibiotics, as misuse can lead to resistance. For immediate relief, you can use saline nasal sprays, perform steam inhalation, gargle with warm salt water, and stay hydrated. Please consult an ENT specialist. They can identify the root cause and prescribe appropriate targeted treatments, such as nasal steroid sprays, antihistamines, or specific medications if a bacterial infection is confirmed.
