First, please be cautious: both FEVRIL Syrup and P125 syrup contain paracetamol. Giving both together can cause an accidental overdose, so please stop one of them immediately. For his blocked nose and mouth breathing, using simple saline nasal drops before bedtime can safely clear his passages. A cool-mist humidifier in his room or sitting with him in a steamy bathroom can also help him breathe easier. Keep him well-hydrated, and please consult your pediatrician to safely adjust his medications and check his symptoms.

For persistent shortness of breath and a fast heart rate, standard initial tests include an electrocardiogram (ECG), basic blood work (to check for anemia or thyroid issues), and spirometry to evaluate your lung function. Since your symptoms were previously dismissed, please consider seeking a second opinion, perhaps from a cardiologist or pulmonologist. To prepare, keep a detailed diary of your symptoms, noting exactly when they occur and how they feel. Your physical health is important, and finding a supportive doctor who will listen to you is a vital next step.

The burning sensation and reduced sense of smell are likely due to the viral infection itself causing inflammation in your nasal passages, rather than the Vicks Action 500, though oral decongestants like phenylephrine can sometimes cause mild dryness. To help soothe your nose, try using a simple saline nasal spray and steam inhalation to restore moisture. This should gradually improve as your body recovers from the cold. However, if these symptoms persist past a week or worsen, please consult a healthcare professional for a gentle evaluation.

Since Vicks hasn't brought relief, your headaches might be linked to sinus congestion that worsens when you lie down at night. To help, try elevating your head with an extra pillow and using steam inhalation before bed to ease congestion. For pain relief, simple over-the-counter paracetamol or ibuprofen can help manage the headache. Staying well-hydrated is also key. If your headache worsens, is accompanied by a stiff neck, fever, or if the cough intensifies, please consult a healthcare professional for a proper evaluation.

Yes, it is completely normal to experience localized itching, redness, or swelling at the injection site 48 hours after a tetanus vaccine. This mild reaction is common and safe during pregnancy. If standard topical remedies haven't helped, applying a cold compress for 15 minutes can soothe the area. For persistent itching, oral antihistamines like cetirizine are generally considered safe during pregnancy, but please consult your obstetrician or midwife before taking any oral medications to ensure they are safe for your specific pregnancy. Try to avoid scratching to prevent infection.

Since you have been using Vicks tablets, VapoRub, and Ventidox DL (which contains doxofylline, montelukast, and levocetirizine) for four days without relief, it is best to consult a doctor. Ventidox DL is a prescription medication, and a healthcare professional should evaluate your chest and symptoms to ensure you have the correct diagnosis. In the meantime, please get plenty of rest, stay well-hydrated, and avoid adding any new medications without professional advice.
