Midodrine is used to treat symptoms of orthostatic hypotension (low blood pressure that happens when there's a change from a lying down or sitting position to a standing position). It belongs to a drug class that works by squeezing your blood vessels in order to raise your blood pressure. You should only take midodrine while you're upright because it can raise your blood pressure to dangerous levels if you take it while lying down. Midodrine can cause side effects like tingling or pricking feeling and goosebumps. Midodrine is available as a generic; there's no brand-name version of this medication.
Midodrine is an alpha-1 adrenergic receptor agonist. It raises blood pressure by tightening the blood vessels in the body.

Taking one 10 mg tablet of midodrine while standing can raise the systolic blood pressure (the top number in the blood pressure reading) by about 15 mmHg to 30 mmHg after an hour. The blood-pressure-raising effects of the medication can sometimes last for up to 2 to 3 hours.
You shouldn't take midodrine when you're lying down because this can raise your blood pressure to a dangerous level (above 200 mmHg). This is why you should make sure to take your last dose of midodrine of the day at least 4 hours before bedtime. You also might not be able to take midodrine if you have high blood pressure because you're at a higher risk of getting this serious reaction. Having uncontrolled high blood pressure can raise the risk of heart problems and stroke. If you have high blood pressure, speak with your provider before starting midodrine to see if this medication is safe for you.
Midodrine might lower your heart rate. Talk with your provider before starting midodrine if you're taking other medications that can also slow your heart rate, such as digoxin (Lanoxin), beta blockers, or certain antidepressants. Let your provider know if you have symptoms of a slow pulse, dizziness, feeling of wanting to faint, or changes in your heartbeat.
Weight gain isn't a known side effect of midodrine. If you experience weight gain while taking this medication, talk to your provider because it could be caused by something else.
Continue taking midodrine only if you have improvement in your orthostatic hypotension symptoms. Your provider will determine how long you can continue to take midodrine. They might stop your treatment if your blood pressure gets too high while you're taking it.
While taking midodrine, let your provider know if you plan to take any over-the-counter medications that can raise your blood pressure. Medications such as cold remedies (with phenylephrine or pseudoephedrine) and pain relievers like ibuprofen might boost the effects of midodrine and raise your blood pressure even higher.
This medication hasn't been studied in pregnant women. But in animal studies, midodrine lowered the chance of survival of unborn babies when it was given at doses higher than what's typically used in humans. Speak with your provider if you're pregnant or planning to become pregnant to discuss whether midodrine is safe for you and your unborn baby.
In 2010, the FDA almost took midodrine off the market after the manufacturer failed to show data that it was safe and worked well for people with orthostatic hypotension in clinical trials. The FDA ultimately allowed midodrine to stay available on the market since there are ongoing trials to determine that it's safe and works well. Talk with your provider if you have any concerns about using midodrine and if the medication is right for you.
Midodrine can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Don't take midodrine while you're lying down or getting ready to lie down. Midodrine can raise your blood pressure to dangerous levels (above 200 mmHg) if you're lying down. Because of this risk, you should only use midodrine if your everyday life is affected by your orthostatic hypotension and if other methods (like support stockings, fluids, or lifestyle changes) aren't enough to help. Let your provider know if you experience symptoms of very high blood pressure when lying down after taking midodrine, such as changes in your heartbeat, pounding in the ears, headache, or blurred vision. Stop this medication right away if these symptoms won't go away.
Midodrine might slow down your heart rate. Talk with your provider before starting midodrine if you're taking other medications that also lower your heart rate, such as digoxin (Lanoxin), beta blockers, or certain antidepressants. Let your provider know if you experience symptoms of a slow pulse, dizziness, feeling of wanting to faint, or changes in your heartbeat.
Because midodrine tightens blood vessels, this medication might make certain health problems worse. Midodrine acts on the blood vessels at the bladder neck, so it can make it worse for people who already have difficulty urinating. In addition, midodrine can affect the eyes, especially in people with diabetes. You also might be at risk if you have a history of eye problems and are also taking fludrocortisone (a medication that's known to cause high eye pressure and glaucoma).
Midodrine gets processed through the liver and is cleared by the body through the kidneys. If your liver or kidneys aren't working properly, the medication might build up in the body, which puts you at risk for side effects. If you have liver problems, your provider might have to follow up with you more often. And if you have kidney problems, your provider might have you start on a lower dose of midodrine. This helps lower your risk for side effects.
