Midodrine belongs to the class of medications known as vasopressors. It is used to relieve symptoms of Low Blood Pressure (such as dizziness, lightheadedness, and fainting) for people with Parkinson's Disease, Diabetes, Bradbury-Eggleston syndrome, and Shy-Drager syndrome. It works by constricting the blood vessels, causing an increase in blood pressure.

Discreet Packaging

Your privacy is important. That's why we send your medication inside a plain delivery box so no one will know what's inside.

The usual recommended starting dose of midodrine for adults is 2.5 mg 3 times daily, taken with or without food. Midodrine may also be taken as frequently as 6 times a day, as long as the maximum daily dose of 30 mg is not exceeded. The last midodrine dose of the day should be taken at least 4 hours before bedtime. People with Kidney Disease may need lower doses.

Midodrine will be started under close medical supervision, usually in a hospital, clinic, or doctor's office. Both lying and sitting blood pressures should be measured every hour for 3 hours after the first and second doses of midodrine therapy and also when there is an increase in dose. Thereafter, blood pressures should be measured daily for the first month, and then twice weekly while on therapy. Midodrine should only be continued if the person appears to have improvement in their symptoms during the initial treatment.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Mar Midodrine.

Bladder problems: Midodrine can cause urinary retention or worsen existing urinary retention. If you have bladder problems, discuss with your doctor how Mar Midodrine may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Mar Midodrine, and whether any special monitoring is needed.

Diabetes: If you have diabetes and have experienced low blood pressure when rising from a sitting or lying position to a standing position, your doctor should closely monitor your condition while you are taking Mar Midodrine.

Heart problems: Midodrine can cause slowing of your heartbeat. Report any slow heartbeat, increased dizziness, or fainting spells to your doctor immediately.

Kidney function: People with reduced kidney function do not clear midodrine from their bodies as quickly as people with regular kidney function. Lower doses of Mar Midodrine and close monitoring by your doctor may be needed.

If you have symptoms of supine hypertension (such as pounding in the ears, headache, heartbeat awareness, or blurred vision), stop using midodrine and contact your doctor immediately.
