Patient was educated on precautions to be exercised while using arterial vasodilators as follows:

1. Be aware of signs and symptoms of hypotension, to avoid any episodes of altered levels of consciousness and accidental falls. One should stay away from activities, such as, driving and operating heavy machinery, until they are used to the side effects caused by the arterial vasodilators.
2. Take a blood pressure reading always before you take the pill. Maintain a log of every day blood pressure reading. If the blood pressure is too low, you can defer taking the medication for that dose. Notify your doctor, if more of such occurrences are happening, so that, your medication dose could be revised.
3. Be aware of signs and symptoms of tachycardia, as extremely high heart rate, secondary to use of arterial vasodilators, can lead to palpitations of the heart and confusion.
4. Try changing the positions very slowly, as sudden change of positions can make the hypotensive episodes even worse and precipitate accidents and falls.
5. Arterial vasodilators are contraindicated in individuals with abnormally high heart rates. So, if your heart rate is being abnormally high (consistently more than 100), with the use of arterial vasodilators, report this to your physician immediately.
6. Arterial vasodilators are contraindicated in individuals with abnormally low blood pressures. Use of arterial vasodilators in these individuals can result in extremely low blood pressure with reduced flow to vital organs. So, if your blood pressures are being consistently low, report this to your physician.
7. Observe compliance with any regular lab work ordered. As these drugs are metabolized significantly in the liver and eliminated by the kidneys, hepatic and renal function could be periodically monitored.
8. If a dose is missed, it should be taken at the earliest notice of noncompliance. If it is time for the next dose, the missed dose can be skipped. Compensating for the missed dose by taking an extra dose can pose serious risk for an episode of extremely low blood pressure and very high heart rate, thus precipitating an emergency.
