Buy Vivactil (Protriptyline Hydrochloride) – Tricyclic Antidepressant (TCA) (Rx)

Vivactil (protriptyline hydrochloride) is a tricyclic antidepressant (TCA) indicated for the treatment of major depressive disorder. It is considered a more activating TCA, meaning it may have stimulating properties compared to other tricyclic antidepressants.

Protriptyline works by inhibiting the reuptake of norepinephrine and serotonin, increasing their levels in the central nervous system. This enhances mood regulation and can improve depressive symptoms, energy levels, and alertness in selected patients.

It is less commonly used today due to the availability of newer antidepressants with improved safety profiles, but it remains an option in treatment-resistant depression or specialist-guided therapy.
