Medication treatment of anxiety is generally safe and effective and is often used in conjunction with therapy. Medication may be a short-term or long-term treatment option, depending on severity of symptoms, other medical conditions, and other individual circumstances. However, it often takes time and patience to find the drug that works best for you.
Medications are commonly prescribed by physicians (family practice, pediatricians, OB-GYNs, psychiatrists), as well as nurse practitioners in many states.
More than one in 10 Americans take antidepressants, the primary type of medication used by people ages 18 to 44. Learn more about how these drugs work.
Four major classes of medications are used in the treatment of anxiety disorders:
Selective Serotonin Reuptake Inhibitors (SSRIs)
SSRIs relieve symptoms by blocking the reabsorption, or reuptake, of serotonin by certain nerve cells in the brain. This leaves more serotonin available, which improves mood. SSRIs (citalopram, escitalopram, fluoxetine, paroxetine, and sertraline) generally produced fewer side effects when compared with tricyclic antidepressants. However, common side effects include insomnia or sleepiness, sexual dysfunction, and weight gain. They are considered an effective treatment for all anxiety disorders, although the treatment of obsessive-compulsive disorder, or OCD, typically requires higher doses.
Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs)
The serotonin-norepinephrine reuptake inhibitor, or SNRI, class (venlafaxine and duloxetine) is notable for a dual mechanism of action: increasing the levels of the neurotransmitters serotonin and norepinephrine by inhibiting their reabsorption into cells in the brain. As with other medications, side effects may occur, including stomach upset, insomnia, headache, sexual dysfunction, weight gain and minor increase in blood pressure. These medications are considered as effective as SSRIs, so they are also considered a first-line treatment for the treatment of anxiety disorders, but not for obsessive compulsive disorder ,where SSRI’s are the preferred first line treatment.
This class of drugs is frequently used for short-term management of anxiety and as an add on treatment, in treatment resistant anxiety disorders.They are not recommended as a treatment for Post Traumatic Stress Disorder. Benzodiazepines (alprazolam, clonazepam, diazepam, and lorazepam) are highly effective in promoting relaxation and reducing muscular tension and other physical symptoms of anxiety. Long-term use may require increased doses to achieve the same effect, which may lead to problems related to tolerance and dependence.
Concerns about long-term use of the benzodiazepines led many doctors to favor tricyclic antidepressants (amitriptyline, imipramine, and nortriptyline). Although effective in the treatment of some anxiety disorders(but not Social Anxiety Disorder), they can cause significant side effects, including orthostatic hypotension (drop in blood pressure on standing), constipation, urinary retention, dry mouth, and blurry vision.
Contact your physician if you experience side effects, even if you are not sure a symptom is caused by a medication. Do not stop taking a medication without consulting with the prescribing physician; abrupt discontinuation may cause other health risks.
Medications will work only if they are taken according the explicit instructions of your physician, but they may not resolve all symptoms of an anxiety disorder.
Clinical trials have shown that low doses of ketamine, a FDA approved anesthetic drug, can lift depression in hours, or even minutes. This rapid antidepressant effect is much faster than the most commonly used antidepressant medications available today, which often take several weeks or longer to work. For some individuals, the antidepressant effects of a single dose of ketamine can last for a week or longer. But ketamine also has properties that make it a potential drug of abuse, and it is a Scheduled drug by the Food and Drug Administration. Currently this treatment is generally reserved for treatment-resistant depression, anxiety, and PTSD, and is considered an experimental treatment. Clinical trials in treatment-resistant depression have also supported the efficacy of an intranasal spray variant of ketamine called esketamine, which is in late-stage testing for FDA approval.

Use these guidelines to talk to your health care professional about medications:
- To avoid potentially dangerous drug interactions, let your mental health care provider know all medications you are taking, including prescriptions and over-the-counter drugs, herbal or dietary supplements, and vitamins. And make sure your family doctor knows you are taking medications for an anxiety disorder.
- Learn when to take a new medication and how, such as on any empty stomach or with food, in the morning or evening, and how frequently.
- Find out how long it should take for the medication to start working and what you should expect when this happens.
- Ask: How will the medication help me? What side effects might occur? Should I avoid any foods or beverages? Are drug interactions with other prescriptions a possibility? How often you should see the doctor for a medication check-up?
- Ask for the prescribing physician’s after-hours phone number in case you develop side effects.
- A good source of information about medications and over-the-counter products is your pharmacist, who should have information about all your prescriptions to advise you about possible drug interactions, side effects, and instructions for use.
If your physician does not want to spend the time to answer your questions, you may need a referral to a different physician.
- Is this new drug/treatment appropriate for me?
What are the drawbacks, if any of this new treatment?
What might be the benefits over my current regimen?
Is the price (typically high when a drug is new) worth the added benefit?
Is this treatment ready for widespread use? Meaning, does it have safety established? Do we know how long people need to be on this treatment? Do we know about any long term issues that could result from this?
