False Anxiety

Distinguishing between a mental health struggle and a biological side effect can help you have more informed, empowered conversations with your healthcare provider.

How these Common Medications Can Be Linked to Anxiety Side Effects

Common Examples/ How they Increase Anxiety

ADHD Stimulants

Adderall, Ritalin, Concerta, Vyvanse

Increases dopamine and norepinephrine, which can raise heart rate and cause "jitteriness."

Corticosteroids

Prednisone, Dexamethasone, Cortisone

Disrupts the body's natural stress response (cortisol), leading to irritability or mood swings.

Asthma Medications

Albuterol (rescue inhalers), Theophylline

Bronchodilators can cause tremors and a racing heart that mimic a panic attack.

Decongestants

Pseudoephedrine (Sudafed), Phenylephrine

As a mild stimulant that constricts blood vessels and increases restlessness.

Thyroid Hormones

Levothyroxine (Synthroid)

If the dose is too high, it speeds up metabolism, leading to palpitations and hyperactivity.

Antidepressants

SSRIs (Prozac, Zoloft), SNRIs (Effexor)

These can cause a temporary spike in "activation" or anxiety during the first 2 weeks of use.

OTC Pain Relief

Excedrin, Anacin (containing caffeine)

Caffeine can overstimulate the nervous system in sensitive individuals.

Drugs that may cause anxiety

Amphetamines

Appetite suppressants

Asthma medications

Caffeine/energy drinks

CNS  depressants (withdrawal)

Cocaine

Nasal decongestants

Steroids

Stimulants

Note: Never stop taking a prescribed medication without consulting your doctor first. Some of these, particularly corticosteroids and antidepressants, require a supervised "taper" to avoid withdrawal symptoms that can actually make anxiety worse.
