Pregabalin, commonly known by its brand name Lyrica, is a medication originally developed for treating epilepsy and nerve pain. However, in recent years, it has shown significant promise in the treatment of various mental health conditions, especially anxiety disorders and generalized anxiety disorder (GAD). Among the different doses available, Pregabalin 150mg has emerged as a commonly prescribed strength for managing psychiatric symptoms effectively and safely.

This article explores the safe use of Pregabalin 150mg, its mental health benefits, possible side effects, and critical considerations for individuals and healthcare providers.

What Is Pregabalin?

Pregabalin is a gamma-aminobutyric acid (GABA) analog, although it does not bind directly to GABA receptors. Instead, it modulates the activity of calcium channels in the central nervous system, reducing the release of certain neurotransmitters like glutamate, noradrenaline, and substance P. This mechanism leads to reduced neuronal excitability, which is beneficial in conditions characterized by overactivity of the nervous system.

Originally Approved Uses:

• Epilepsy (as adjunct therapy)

• Neuropathic pain (diabetic neuropathy, postherpetic neuralgia)

• Fibromyalgia

• Generalized anxiety disorder (GAD) in several countries

Why Pregabalin for Mental Health?

Safe Dosage: Why 150mg?

Recommended Psychiatric Doses:

• Another trial in Europe showed that 150–300mg/day of Pregabalin was well tolerated and effective in improving sleep and reducing anxious rumination.

• Patients who had not responded well to SSRIs (like fluoxetine or sertraline) experienced better compliance and fewer side effects with Pregabalin.
