Indications 

Proamatine is a prescribed medication indicated for the treatment of orthostatic hypotension (OH), a condition characterized by a sudden drop in blood pressure upon transitioning from a seated or lying position to standing. 

This medication is recommended only for patients with significantly impaired lives, even after receiving standard clinical care, including non-pharmacologic treatment (such as support stockings), fluid expansion, and lifestyle changes. 

Classified as an alpha-adrenergic agonist, Proamatine works by constricting blood vessels, thereby raising blood pressure. 

Uses and Dosage 

Before taking Proamatine and with each prescription refill, carefully review its medication guide and patient information leaflet. If you have any queries, seek clarification from your healthcare provider or pharmacist. 

Proamatine dosage is determined based on individual medical conditions and response to the treatment.  

Your physician will likely initiate this medication at a low dosage and gradually adjust it to minimize potential side effects. Adhere to your physician’s instructions carefully. 

Typically, Proamatine is taken three times a day during daytime hours (ideally in the morning upon waking, midday, and late afternoon (no later than 6 P.M.). It can be taken with or without food, with a minimum gap of 3 to 4 hours between doses. 

For optimal results, take this medication around the same time each day.  

Avoid taking this medicine after the evening meal or less than 4 hours before bedtime. Similarly, do not take your dose if you anticipate an extended period of lying down, such as napping.  

Inform your doctor if your condition persists or worsens. Proamatine should be continued solely for individuals whose symptoms show improvement during the course of treatment.
