In general, it is acceptable to drink water during a hypertensive episode. When managing high blood pressure, oral medications are typically required, and these are usually taken with lukewarm water. Therefore, drinking water during a hypertensive attack is permissible, but only in moderation. Excessive water intake should be avoided, as it may lead to sodium and water retention, potentially triggering reflexive increases in blood pressure, which could be harmful to the patient's health.
