Nausea, blood pressure, and permanent pigment: the real safety picture

PT-141 has a well-characterized safety profile, and it is not a gentle one. This unit covers the dominant adverse events in order of importance: nausea, a transient blood-pressure rise, and rare but permanent focal hyperpigmentation.

It also covers the naltrexone interaction and the firm contraindications. As everywhere in this course, this is education, not medical advice, and the goal is to hold the reassuring and the concerning parts honestly at once.
