What is zephirin hydrochloride?

Zephirin hydrochloride, also known as phenylpropanolamine, is a medication primarily used as a decongestant and appetite suppressant. It works by narrowing blood vessels in the nasal passages to reduce swelling and congestion. However, its use has declined due to safety concerns and potential side effects, including an increased risk of stroke. It is important to consult a healthcare professional before using any medication containing zephirin hydrochloride.
