Hey. I found this on Healthline. It is not about breaking a, but I thought it would be helpful. "Adults 18 and over typically don’t need medication for a fever under 102°F (38.9°C). Fevers above that number may be reduced by medication. If your fever goes above 103°F (39.4°C) or doesn’t respond to treatment, a call to the doctor is warranted. Adults with a fever and other symptoms, such as a stiff neck, severe pain anywhere in the body, or shortness of breath, should seek medical attention."
