Midive is a medicine that widens blood vessels in the lungs, making it easier for the heart to pump blood and improving your ability to move.
You usually start with one 1 mg tablet three times a day for two weeks. Your doctor may then slowly increase your dose.
Take tablets every 6–8 hours, with or without food. If you have trouble swallowing, you can crush the tablet and mix it with water or soft food.
The maximum daily dose is usually 7.5 mg, taken in three doses.
