It is important that your doctor check your progress at regular visits to make sure that this medicine is working properly.
Ask your doctor about checking your pulse rate before and after taking minoxidil. Then, while you are taking this medicine, check your pulse regularly while you are resting. If it increases by 20 beats or more a minute, check with your doctor right away.
While you are taking minoxidil, weigh yourself every day. A weight gain of 2 to 3 pounds (about 1 kg) in an adult is normal and should be lost with continued treatment. However, if you suddenly gain 5 pounds (2 kg) or more (for a child, 2 pounds [1 kg] or more) or if you notice swelling of your feet or lower legs, check with your doctor right away.
Do not take other medicines unless they have been discussed with your doctor. This especially includes over-the-counter (nonprescription) medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, since they may tend to increase your blood pressure.
