Make sure to stand up and move around the plane when it is safe to do so. Avoid eating salty snacks and consuming alcohol and sedatives. Also, if you take blood pressure medication, don't forget to pack it in your carry-on so you can take it as needed.

Yes, you can absolutely take blood pressure medication on a plane in 2026, and it is highly recommended to keep it in your carry-on luggage rather than checked bags. Under current TSA and international aviation standards, solid pills and tablets are not subject to the 100ml liquid restrictions. While you aren't strictly required to keep them in their original pharmacy bottles for domestic travel, doing so—along with a copy of your prescription—is a high-value safety measure for international customs, where officials may need to verify "controlled" substances. If your medication is in liquid form and exceeds 100ml, it is typically exempt from the limit as long as you declare it to security for separate screening. Staying hydrated and following your dosage schedule is critical during flight, as cabin pressure changes and mild dehydration can cause temporary fluctuations in blood pressure, making your medication a vital "travel essential."
