FDA Box Warning

• Drug may cause serious adverse effects (such as pericardial effusion occasionally progressing to tamponade) and may exacerbate angina pectoris. Reserve it for hypertensive patients who respond inadequately to maximum therapeutic doses of diuretic and two other antihypertensives.

• Give under close supervision, usually concurrently with therapeutic doses of beta blocker to prevent tachycardia and increased myocardial workload. Usually, drug also must be given with diuretic to prevent serious fluid accumulation. Patients with malignant hypertension and those already receiving guanethidine should be hospitalized when therapy begins so they can be monitored to avoid too rapid, or large orthostatic, blood pressure decreases.


Reduces blood pressure by relaxing vascular smooth muscle, causing vasodilation. Action in hair growth stimulation unclear; vasodilatory action may enhance microcirculation around hair follicles.

Patient discussion about Rogaine

Q. Is their a drug available to regain my energy back from having hypothyrodiam? I was diagnosed three years ago with Hypothyroidism. I have been using medication to level out my thyroid level. The lack of energy and weakness I am experiencing at the age of 42 is maddening. I want my life back the way it was. I am tired of feeling tired and zombie like.

A. Hormone replacement has to be continued throughout your life; Zoe is probably right: you may need a higher dose. Talk to your doctor about the fatigue, you should have regular check-ups again to monitor your hormone levels to get the right dosage.

You can always ask for more information about your condition: whether it's primary or secondary hypothyroidism and what may/may not have caused it, or what you can do to improve your symptoms.
