fenylefryna
Fenylefryna is a medication primarily used as a decongestant and to raise blood pressure. It belongs to a class of drugs called alpha-1 adrenergic agonists. As a decongestant, it works by constricting blood vessels in the nasal passages, which reduces swelling and helps to clear a stuffy nose. This action is often utilized in over-the-counter cold and allergy medications. Beyond its decongestant properties, fenylefryna can also be administered intravenously in medical settings to treat hypotension, or low blood pressure, particularly during surgery or in cases of shock. It achieves this by increasing peripheral vascular resistance. While generally considered safe when used as directed, fenylefryna can have side effects. These may include increased heart rate, elevated blood pressure, headache, and nervousness. It is important to use fenylefryna as recommended by a healthcare professional or the product's instructions, as overuse or misuse can lead to adverse effects. Individuals with certain medical conditions, such as heart disease, high blood pressure, or thyroid problems, should consult their doctor before using fenylefryna.
