Why is this medication prescribed?

Neosynephrine is a brand name for the medication phenylephrine, which is a synthetic sympathomimetic drug. It is commonly prescribed for various medical conditions to alleviate symptoms related to nasal congestion, hypotension (low blood pressure), and as a mydriatic (to dilate the pupil of the eye).

  • Nasal congestion: Neosynephrine is often prescribed as a nasal spray or drops to relieve nasal congestion caused by conditions such as the common cold, sinusitis, or allergies. It works by constricting the blood vessels in the nasal passages, which reduces swelling and allows for easier breathing.
  • Hypotension: In some cases of low blood pressure, particularly in medical settings or emergencies, Neosynephrine may be administered intravenously to help raise blood pressure and maintain adequate perfusion to vital organs.
  • Mydriatic use: Neosynephrine is used by eye care professionals to dilate the pupils during eye exams or certain eye surgeries. This dilation allows for a better view of the structures within the eye.
