Medications That May Cause Anxiety

Certain medications can cause you to feel anxious or agitated, either while you are taking them or after you stop. For people who have an anxiety disorder, these medications can cause a worsening of symptoms. This is sometimes called substance-induced anxiety.
Allergy and cold medications that contain the ingredient pseudoephedrine can cause restlessness and nervousness. Other side effects include difficulty sleeping, problems breathing, and a pounding heartbeat. These side effects can mimic symptoms of anxiety and make you feel as if you are having a panic attack, which in turn can lead to a worsening of anxiety symptoms.
The main ingredient in asthma inhalers is albuterol, which is effective at opening breathing passages, but the side effects include nervousness, a fast and irregular heartbeat, and difficulty breathing. Like pseudoephedrine, these side effects can mimic symptoms of anxiety, making you feel more anxious.
Stimulant medications for ADHD
Stimulant medications, such as methylphenidate, are used to treat attention-deficit/hyperactivity disorder (ADHD) and narcolepsy. Side effects include agitation, nervousness, feeling suspicious of others, and an abnormally excited mood. If anxiety is a result of living with ADHD, treating it with stimulant medications may help. If, however, these medications worsen your anxiety, talk to your doctor about non-stimulant treatments.
Oral birth control
Taking oral hormonal contraceptives might shrink portions of the brain that are responsible for emotional regulation, rewards, and inward-directed thought, according to a study published in Human Brain Mapping. These changes might cause increased anxiety and depressive symptoms in women taking oral birth control.
According to the Hospital for Special Surgery, corticosteroids, often referred to as steroids, can cause mood changes, including anxiety. Some commonly prescribed steroids include prednisone, methylprednisolone, dexamethasone, and hydrocortisone.
What you can do
Before taking any prescription medications, talk to your doctor and pharmacist about potential side effects. If you already live with an anxiety disorder, pay particular attention to how you feel after taking the medication. If it worsens your anxiety symptoms, especially to the point that you are unable to function in daily life, talk to your doctor about other treatment options.
