After taking the antipyretic medicine, you can drink water no matter how long it takes, and when you take the antipyretic medicine, it is usually served with water, so there is no conflict between taking the antipyretic medicine and drinking water. If you have nausea during the period of taking antipyretic drugs, you can temporarily do not drink water, wait for ten minutes or half an hour, when the nausea subsides a little and then drink water, to prevent drinking too much water after taking antipyretic drugs, resulting in increased nausea and vomiting, antipyretic drugs are likely to vomit out, thus not being able to play the effect. Therefore, the consideration that you can not drink water after taking antipyretic drugs is only one case, other cases do not affect drinking water, and after taking antipyretic drugs need to sweat, if the body is in a state of dehydration, it is necessary to replenish water as a source of sweating.
