Since your father's oxygen levels have dipped to 91-92% and his fever persists despite taking paracetamol (Crocin 650) and his other medications, he requires immediate medical evaluation. An oxygen saturation below 94% indicates that he may need supplemental oxygen and a prompt adjustment of his treatment plan by his doctor. Please contact his physician or visit the nearest emergency room right away. While you arrange this, you can encourage him to lie on his stomach (awake proning) to help improve his oxygenation, and continue monitoring his levels closely.

It is very reassuring that your tests for malaria, dengue, and typhoid are negative. Since paracetamol alone isn't breaking the fever, continuing the paracetamol and ibuprofen combination temporarily is reasonable, but please follow the package dosing closely to protect your stomach and liver. Given your symptoms have lasted five days, this could be a persistent viral syndrome or a developing bacterial infection. I recommend seeing a doctor for a physical exam, particularly to listen to your lungs. In the meantime, rest, stay well-hydrated, and use warm saline gargles.

As he is experiencing severe lethargy, pale skin, and is not drinking well alongside his fever and cough, it is very important that he is evaluated by a doctor immediately. Please take him to the nearest emergency room or pediatric urgent care right away. These symptoms can be signs of severe dehydration or a more serious infection that needs prompt professional care. While on the way, try to keep him comfortable, but do not give any new medications without a doctor's advice.

Daily use of pain relievers can actually worsen headaches and irritate your stomach. The safest first step is to see a primary care doctor. They can evaluate your symptoms, safely guide you through reducing pain medication, and contact you with a therapist or psychiatrist to support your mood, sleep, and stress.

It is best not to reduce the prescribed 3 ml dose of Crocin (paracetamol). Pediatric medication doses are carefully calculated based on your 14-month-old's weight to ensure they are both safe and effective, not on how high the fever is. Giving a lower dose of 2 ml might not be enough to help them feel better if the fever returns. Please continue with the prescribed 3 ml dose as directed by your doctor, keeping at least 4 to 6 hours between doses.

Since he has been on antibiotics and fever reducers like acetaminophen or ibuprofen without improvement, it is very important to have him re-evaluated by his pediatrician. Persistent symptoms can sometimes mean the infection is viral (which antibiotics won't cure) or requires a different treatment. In the meantime, keep him comfortable, offer plenty of fluids to stay hydrated, and use a cool-mist humidifier for his cough. Please contact your doctor today to ensure he gets the right care.
