This blog post is intended for informational and educational purposes only and does not constitute medical advice, diagnosis, or treatment. Always seek the advice of your physician, psychiatrist, or other qualified healthcare provider with any questions you may have about a medical condition or medication. Never disregard professional medical advice or delay seeking it because of something you have read on this website.
Medications affect individuals differently, and decisions about starting, stopping, or adjusting medication should always be made in consultation with a healthcare provider.
Medications seem to be everywhere. Whether prescribed by a psychiatrist, primary care physician, or nurse practitioner, pharmaceuticals have become a regular part of modern life. But have you ever been given a clear explanation of how medications actually work?
Often, time constraints and discomfort around sensitive topics (like medication-related sexual dysfunction) can prevent deep conversations between providers and patients. So let's take a moment to walk through the basics together.
Common Types of Medications and Mental Health
Many medications prescribed today fall into categories like stimulants, SSRIs, SNRIs, anxiolytics, and benzodiazepines. They’re used to treat a range of symptoms related to depression, mood disorders, and anxiety. Each medication has specific attributes, including:
Indications: The conditions a medication is FDA-approved to treat. "Off-label" use refers to prescribing a drug for something it wasn’t originally approved for, often based on emerging research or clinical experience.
Dosage: The amount and frequency of a medication are tailored to an individual's age, weight, and the medication's half-life (how long it remains active in the body).
Mechanism of Action: How a drug works inside your body, often by interacting with brain receptors or neurotransmitters.
Side Effects: Unintended effects that may arise when taking a medication. Side effects can vary based on dosage, timing, or interactions with other drugs.
Understanding these elements gives you a foundation to better advocate for yourself when discussing medication options with your provider.
The Brain Basics: Your Internal Control Centers
To really understand medications, you need to know a little about the layout of your brain. Each lobe plays a part in how you think, feel, and move, and medications often target specific pathways within this intricate system.

Here’s a quick tour:
Frontal Lobe: Manages planning, organizing, problem-solving, short-term memory, and voluntary movement.
Parietal Lobe: Processes sensory information like touch, taste, texture, and temperature.
Occipital Lobes: Handle visual information, helping you recognize objects and images.
Temporal lobes deal with sensory input related to smell, taste, and sound, and play a significant role in memory storage.
The brain’s chemical Messengers
Next, we have chemical messengers. They move through the parts of your brain and your central nervous system.. You may have heard the term 'neurotransmitter'. This is just a fancy word for the chemicals in your brain that affect your mental state and sometimes your physical state, too. These little messengers are key to how medications work in the brain.
Below is a simplified explanation of each:
Norepinephrine
Affects attention, arousal, and the "fight-or-flight" stress response. It's linked to anxiety and stress disorders.
Dopamine
Involved in motivation, reward, addiction, impulse control, and motor functions. Imbalances can contribute to depression, ADHD, schizophrenia, and more.
Glutamate
An excitatory neurotransmitter essential for brain communication. Imbalances are associated with conditions like Parkinson's, Alzheimer's, depression, schizophrenia, and anxiety.
GABA (Gamma-Aminobutyric Acid)
An inhibitory neurotransmitter that calms the brain. Low GABA levels are associated with anxiety, difficulty concentrating, and mood disorders.
Serotonin
Regulates mood, appetite, sleep patterns, body temperature, and emotions, such as aggression. Low serotonin is often linked to anxiety, depression, OCD, panic disorders, and PTSD.
Next, you have to know that medications fall into categories, often referred to as drug classes. These pathways are related to the brain chemicals we just covered, usually affecting how much or little is available for use in the brain and body. Below is a simplified explanation of a few common drug classes:
SSRIs (Selective Serotonin Reuptake Inhibitors)
help maintain higher levels of serotonin in the brain, supporting mood regulation. Examples: Fluoxetine (Prozac), Sertraline (Zoloft), Escitalopram (Lexapro)
SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors)
impact both serotonin and norepinephrine to boost mood and reduce anxiety. Examples: Venlafaxine (Effexor XR), Duloxetine (Cymbalta)
Stimulants
Increase dopamine and norepinephrine levels, helping improve focus and executive function. Examples: Vyvanse, Methylphenidate (Ritalin, Concerta), Amphetamine salts (Adderall)
Anxiolytics
Are used to reduce anxiety symptoms. Examples: Buspirone (BuSpar)
Benzodiazepines
Enhance GABA activity to calm the brain and reduce acute anxiety. Examples: Lorazepam (Ativan), Diazepam (Valium), Alprazolam (Xanax)
Each medication essentially acts like a tiny chemical messenger, shifting the balance of your brain's natural chemistry to create a different outcome in how you think, feel, or behave. Here are a few examples of medications following the above information.
Please note that these DO NOT include all side effects, dosages, indications, or drug interactions. They do not constitute medical advice. You should consult your healthcare provider before making decisions based on the information on this website.
Why This Matters
Understanding the basics of how medications work can empower you to make informed decisions about your mental and physical health. It gives you the language to ask better questions, notice side effects sooner, and advocate for yourself in conversations with your provider. In a world where pharmaceuticals are often handed out quickly, taking the time to understand your brain and body is an act of care and empowerment.
But Wait, There's More
Now that you know the basics of what all this jargon means, you can utilize tools like Drugs.com or Rxlist.com to find out more information that in conjunction with conversations with your medical providers and care team may help you better understand what medications are right for you, what side effects exists, common usages, and potential drug interactions. Being armed with the knowledge of how your body works and how medications work with it can help you feel empowered to have conversations with your doctors and providers. It can also increase your understanding of why medications should be taken as prescribed and why it's important not to stop without the supervision and guidance of a medical provider. It can also help you navigate complex or embarrassing conversations about side effects.
Don't be afraid to ask for extra time from your provider to ensure you truly understand your medications.
