For immediate relief, you can take an over-the-counter pain reliever like Paracetamol (Acetaminophen) or Ibuprofen to help ease your body aches. For the runny nose, an antihistamine such as Loratadine or Cetirizine is effective. Alternatively, an all-in-one multi-symptom cold medication can address all these symptoms at once. Please read the labels carefully and do not combine medications containing the same active ingredients (especially paracetamol) to avoid accidental overdose. Rest well, stay hydrated with warm fluids, and consult a local pharmacist or doctor to ensure these options are safe for you, especially if you have pre-existing conditions like high blood pressure.
