How Do Psychiatric Medications Work?
Psychiatric medications work by adjusting brain signaling systems. They influence chemical messengers (neurotransmitters) such as:
-
Serotonin – mood, anxiety, sleep
-
Norepinephrine – energy and alertness
-
Dopamine – motivation, pleasure, focus
-
GABA – calming signal in the brain
-
Histamine – wakefulness
Psychiatric medications do not change who you are.
They do not erase trauma.
They do not create artificial happiness.
When effective, they reduce symptom intensity so you can regulate more easily, think clearly, and engage more fully in therapy.
Antidepressants for Anxiety and Depression
Antidepressants (including SSRIs and SNRIs) are commonly prescribed for:
-
Major depressive disorder
-
Generalized anxiety disorder
-
Panic disorder
-
OCD
-
PTSD
-
Chronic pain conditions
They typically take 2–6 weeks to show full benefit.
Common Early Side Effects of Antidepressants
-
Nausea
-
Headache
-
Sleep changes
-
Sexual side effects
-
Mild activation or jitteriness
Clients often describe:
-
“My mood improved gradually.”
-
“My worry quieted.”
-
“I feel steadier.”

Mood Stabilizers for Bipolar Disorder
Mood stabilizers are most often used in bipolar disorder and significant mood instability.
They help reduce the intensity of emotional highs (mania or hypomania) and lows (depression).
Clients often report:
-
“I feel more even.”
-
“My emotions aren’t as extreme.”
-
“My lows aren’t as low.”
Some mood stabilizers require blood monitoring and gradual dose adjustments.
Anti-Anxiety Medications
There are two broad categories of anxiety medications:
Benzodiazepines
These medications work quickly and may be prescribed short-term for acute anxiety or panic. They are not typically recommended for long-term daily use due to risk of physical dependence.
Non-Benzodiazepine Options
These include medications such as buspirone, hydroxyzine, or propranolol. They often:
-
Work more gradually
-
Target physical symptoms of anxiety
-
Provide steady symptom relief
Many clients describe these as:
-
“Subtle but steady.”
-
“Helpful for the physical anxiety.”

ADHD Medications
ADHD medications are typically divided into stimulant and non-stimulant categories.
Stimulants increase dopamine and norepinephrine to improve focus and task initiation.
Common experiences include:
-
Improved concentration
-
Reduced distractibility
-
Appetite suppression
-
Sleep changes
-
“Crash” when medication wears off
Non-stimulant options may be preferred when anxiety or sleep concerns are present.
Sleep Medications
Sleep medications may help with:
-
Falling asleep
-
Staying asleep
-
Regulating sleep rhythm
However, long-term sleep improvement often depends on behavioral sleep strategies.
If sleep difficulty is connected to anxiety, trauma, or postpartum adjustment, therapy can address underlying causes.
Important Psychiatric Medication Safety Information
Discontinuation Symptoms
Some medications can cause temporary symptoms if stopped abruptly. These may include dizziness, irritability, or “brain zaps.” This is not addiction. Always taper medications with medical guidance.
What Is Serotonin Syndrome?
Serotonin syndrome is a rare but potentially serious reaction caused by excessive serotonin activity.
Symptoms may include:
-
Agitation
-
Confusion
-
Rapid heart rate
-
Heavy sweating
-
Tremors
-
Diarrhea
-
Muscle twitching
-
High fever (in severe cases)
It typically develops within hours of starting or increasing a medication.
Severe symptoms require urgent medical care.
What Is Akathisia?
Akathisia is a medication-related side effect that causes an internal sense of restlessness. It can feel similar to anxiety and should be reported to your prescriber.
Psychiatric Medication During Pregnancy & Postpartum
The perinatal period includes pregnancy, the postpartum period, and the first year after birth.
Medication decisions during this time require individualized risk–benefit discussions.
Important considerations:
-
Untreated depression and anxiety also carry risks for both parent and baby.
-
Many commonly used antidepressants have reassuring reproductive safety data.
-
Breastfeeding compatibility varies by medication but many options are considered acceptable.
