What Should I Know About Phenylephrine (5mg), Such As Its Uses, Dosage, And Safety Precautions?

Phenylephrine is a medication commonly used to relieve nasal congestion caused by colds, allergies, or sinus infections. It works by narrowing the blood vessels in the nasal passages, reducing swelling and congestion. The typical adult dose is 5mg every 4 hours, but it's important not to exceed the recommended amount on the package or as advised by a healthcare provider.

Safety precautions include avoiding phenylephrine if you have high blood pressure, heart disease, or are taking certain medications like MAO inhibitors. Side effects can include increased heart rate, dizziness, or trouble sleeping. Always consult with a healthcare professional before starting any new medication, especially if you have underlying health conditions.
