Summary
Midodrine is used to treat orthostatic hypotension, which is low blood pressure when standing. It helps reduce symptoms like dizziness and fainting. It's often used when other treatments haven't worked and can be used alone or with other therapies to manage low blood pressure.
Midodrine works by stimulating alpha-adrenergic receptors, which are proteins in your blood vessels. This causes the blood vessels to narrow, increasing blood pressure. Think of it like tightening a garden hose to increase water pressure, improving blood flow and reducing symptoms of low blood pressure.
The usual starting dose of Midodrine for adults is 2.5 mg to 10 mg, taken two to three times a day during waking hours. Your doctor may adjust the dose based on your response and needs. The maximum recommended dose is 40 mg per day.
Common side effects of Midodrine include tingling of the scalp, chills, and goosebumps. These occur in a small percentage of people. If you experience new symptoms after starting Midodrine, they might be temporary or unrelated to the medication.
Midodrine can cause high blood pressure, especially when lying down, which is called supine hypertension. Don't take Midodrine if you have severe heart disease, high blood pressure, or an overactive thyroid, which is called hyperthyroidism. Always consult your doctor about your health conditions before starting Midodrine.

Follow your doctor's instructions to minimize risks.
Is it safe to drink alcohol while taking Midodrine?
It's best to avoid alcohol while taking Midodrine. Alcohol can lower blood pressure, which may counteract the effects of Midodrine and increase the risk of side effects like dizziness or fainting.
