In the case of tonsillitis, antibiotics may not always be necessary as the infection can sometimes go away on its own. It is important to consult with a doctor to determine if antibiotics are needed based on the specific type of infection. Additionally, it is important to be cautious when taking medications like Tylenol Complete, as they can have side effects such as increased blood pressure. Avoid sharing utensils and glasses if you have symptoms of a contagious infection.
