Given his history of tobacco use and hoarseness lasting more than two weeks, it is highly recommended to proceed with the recommended camera test (laryngoscopy) advised by his specialist. This is a very routine, safe, and quick procedure that allows the doctor to look directly at his vocal cords to find the exact cause of the issue. Getting this clear picture is the best next step to help him get the right treatment and recover his voice. Please proceed with the test as planned.

Since it is one-sided and has lasted two months, the cause might not be a typical infection or allergy. It could be related to localized inflammation, acid reflux affecting the throat, or even muscular tension. I highly recommend seeing an ear, nose, and throat (ENT) specialist. They can perform a simple, in-office visual exam called a laryngoscopy to look closely at the area and guide the next steps to help you find relief.

Please be reassured that your prescribed treatment, including Levofloxacin (Levoflox 250), Rabeprazole (Rabedif), and Montelukast/Fexofenadine (Montair FX), is highly appropriate for a bilateral sinus infection. Since you only started yesterday, it is completely normal to not feel relief yet; antibiotics typically take 48 to 72 hours to show noticeable improvement, and full recovery can take one to two weeks. I recommend resting, staying hydrated, and using warm compresses. If you develop a high fever, severe eye swelling, or see no improvement after three full days, please contact your doctor or seek a second opinion.

Antihistamines such as cetirizine or loratadine can help reduce swelling and sneezing associated with cold allergies, and nasal saline sprays can assist remove congestion. To naturally lessen symptoms, stay away from irritants, keep your living space dust-free, and drink enough of water.

Since this cough and mucus have lasted for over two years despite using medications like Grilinctus and Montair FX, you should not ignore it. This is a common post-COVID issue, but it requires proper evaluation. I highly recommend scheduling an appointment with a pulmonologist (a lung specialist). They can check for airway sensitivity or post-nasal drip and guide him toward the right treatment.

Montair FX (montelukast and fexofenadine), Doxy 100 (doxycycline), Brozedex syrup, or azithromycin?contain sulfa. They are safe to take regarding a sulfa allergy. However, combining two antibiotics like doxycycline and azithromycin is unusual for a COVID-19 cough and can cause stomach discomfort. I highly recommend consulting their doctor to confirm if both antibiotics are necessary. Please ensure they stay well-hydrated and get plenty of rest.
