Please do not give him Azee (azithromycin) without consulting his pediatrician first, as antibiotics are only for bacterial infections. More importantly, please stop giving Piriton CS, Sinarest AF, and Ascoril D together. These medications contain overlapping ingredients, which can be unsafe and cause an accidental overdose for a 3-year-old. Since he has a worsening cough and a new fever a week after his MR vaccine, it is best to have him evaluated by his pediatrician. They will safely check his chest and prescribe the correct medications and dosages for his weight.

I recommend pausing the Ascoril D syrup and consulting your pediatrician before giving another dose. Cough medicines containing dextromethorphan, phenylephrine, and chlorpheniramine are generally not recommended for children under four years old without direct medical supervision, as safe dosing must be carefully calculated based on her exact weight. To help soothe her cough safely in the meantime, you can use a cool-mist humidifier in her room or offer warm fluids.

Since your cough returned after finishing Nasofex-L and Ascoril D Plus, and is triggered by eating and physical activity, it might be related to acid reflux or airway sensitivity. Your next best step is to consult your prescribing doctor for a follow-up evaluation. In the meantime, try eating smaller, more frequent meals, avoid lying down immediately after eating, and stay well-hydrated with warm fluids. This will help soothe your throat while your doctor determines the most effective next steps for your recovery.

For an infant, it is very important to consult your pediatrician before continuing Ascoril LS (which contains levosalbutamol, ambroxol, and guaifenesin), as a 5ml dose three times a day can be too high and may cause side effects like a rapid heart rate. For a mild cough with no other symptoms, keeping him well-hydrated with breast milk or formula and using a cool-mist humidifier can safely soothe his airways. Please have his pediatrician evaluate him to determine the safest care plan.

Ascoril D Plus is formulated primarily for a dry cough and contains an antihistamine (chlorpheniramine) and a cough suppressant (dextromethorphan). While it might offer mild relief if your sore throat is caused by post-nasal drip, it is not the direct treatment for a sore throat alone. For targeted relief, I highly recommend trying warm saline gargles, staying well-hydrated, and using throat lozenges. Simple pain relievers like paracetamol can also help soothe the pain. Please consult a healthcare professional if your symptoms persist.

Since it has been getting worse over the week and hasn't improved with cough drops, Ascoril, or Kuffdryl, it is really important that you see a healthcare provider for a physical exam. They can listen to your lungs to check for underlying causes like bronchitis. In the meantime, please try to rest, stay well-hydrated with warm fluids, and use a humidifier to soothe your throat. Please seek professional medical care soon so you can get the right targeted treatment and start feeling much better.
