Mental Health Medications

Please Note: You should discuss any information on this page with your mental health care provider.

Psychiatric medications influence the brain chemicals that regulate emotions and thought patterns. They’re usually more effective when combined with psychotherapy. In some cases, medicines can reduce symptoms so other methods of a treatment plan can be more effective. For example, a medication can ease symptoms of depression like loss of energy and lack of concentration, allowing an individual to engage more in talk therapy.

However, predicting who will respond to what medication can be difficult because different medications may work better for one person than for another. Doctors usually review clinical records to see if evidence exists for recommending one medicine over another. They also consider family history and side effects when prescribing medication.

Be persistent until you find the medication (or combination of medications) that works for you. A few psychiatric medications work quickly, and you will see improvements within days, but most work more slowly. You may need to take a medication for several weeks or months before you see improvement. If you feel as though a medication isn’t working, or you’re having side effects, consult with your provider to discuss possible adjustments. Many people won’t experience side effects, or they will go away within a few weeks, but if they continue, changing medications or dosage will often help.

Types of Medication

Treatment typically consists of pills or capsules, taken daily. Some can also be available as liquids, injections, patches or dissolvable tablets. People who have difficulty remembering to take medications daily or people with a history of stopping medication may have better results by taking medication as a shot at the doctor’s office once or twice a month.

Your provider will likely start at a low dose and slowly increase dosage to achieve a level that improves symptoms. Following your provider’s instructions will reduce side effects and discomfort when possible. Understand the role medicines can play for key symptoms.

When stopping a medication, work with your doctor to taper off properly. This allows brain chemicals to adjust to the change. Stopping medication suddenly can result in uncomfortable side effects.

In some cases, psychiatric medication may be a short-term aid taken only for a few months. In others, medication may be long-term, or even lifelong. Some people are afraid that taking a medication will change their personality, but most find that medication allows them to take charge of their lives.

Medications for mental health conditions fall into the following major categories:

Antipsychotics

Antipsychotics developed in the mid-20th century are often referred to as first-generation or typical antipsychotics, while antipsychotics developed more recently are referred to as second-generation or atypical antipsychotics. These medications reduce or eliminate symptoms of psychosis (delusions and hallucinations) by affecting the brain chemical called dopamine.

All antipsychotics play a vital role in treating schizophrenia and schizoaffective disorder. Second-generation antipsychotics can also be used to treat acute mania, bipolar disorder and treatment-resistant depression.

Second-generation antipsychotics aren’t necessarily better than first-generation, but they do have different side effects. First-generation antipsychotics are more likely to cause movement disorders like tardive dyskinesia—an uncomfortable condition in which the brain misfires and causes random, uncontrollable muscle movements or tics. Second-generation antipsychotics are more likely to result in weight gain, which can lead to health complications such as metabolic syndrome. Work with your provider to find the best medication for you.

Antidepressants

These medications improve symptoms of depression by affecting the brain chemicals associated with emotion, such as serotonin, norepinephrine and dopamine.

Selective serotonin reuptake inhibitors (SSRIs) and selective norepinephrine reuptake inhibitors (SNRIs) are newer antidepressants that have fewer side effects than older drugs, but no medication is entirely free of side effects. Potential side effects of SSRIs and SNRIs include:

  • Nausea
  • Nervousness, agitation or restlessness
  • Dizziness
  • Reduced sexual desire/difficulty reaching orgasm/inability to maintain an erection
  • Insomnia, drowsiness
  • Weight gain or loss
  • Headache
  • Dry mouth
  • Vomiting
  • Diarrhea

One antidepressant (Bupropion) affects mostly the brain chemical dopamine and thus forms a category of its own. Meanwhile, older types of antidepressants, including tricyclics and monoamine oxidase inhibitors (MAOIs), may be prescribed by a mental health professional if newer medications do not seem to be effective. Common side effects of tricyclics include:

  • Dry mouth
  • Blurred vision
  • Constipation
  • Urine retention
  • Drowsiness
  • Increased appetite, leading to weight gain
  • Drop in blood pressure when moving from sitting to standing, which can cause lightheadedness
  • Increased sweating

MAOIs are the least-prescribed of all antidepressants because they can cause dangerously high blood pressure when combined with certain foods or medications. People taking MAOIs must watch their diets carefully to avoid potentially life-threatening complications. Off-limits foods typically include aged cheese, sauerkraut, cured meats, draft beer and fermented soy products such as miso, tofu or soy sauce. Some people may have to avoid wine and all forms of beer. 

Some antidepressants may be useful for post-traumatic stress disorder (PTSD), generalized anxiety disorder and obsessive-compulsive disorder (OCD) but may require higher doses. Symptoms of depression that are part of a bipolar disorder need more careful assessment because antidepressants may worsen the risk of mania and provide little relief from depressive symptoms. As always, ask your doctor about what treatment options are right for you.

Anti-Anxiety Medications

Certain medications work solely to reduce the emotional and physical symptoms of anxiety. Benzodiazepines such as alprazolam (Xanax) can treat social phobia, generalized anxiety disorder and panic disorder. These medicines work quickly and are very effective in the short-term. However, people prone to substance abuse may become dependent on them.

Increasing the dosage over time might be necessary because the body can become used to these medications and require larger doses for the same therapeutic effect. People who stop taking benzodiazepines suddenly may experience unpleasant withdrawal symptoms. Other potential side effects include:

  • Low blood pressure
  • Decreased sex drive
  • Nausea
  • Lack of coordination
  • Depression
  • Unusual emotional dysfunction, including anger and violence
  • Memory loss
  • Difficulty thinking

Mood Stabilizers

Mood stabilizers commonly treat the mood swings associated with bipolar disorder. The oldest of them, lithium, has been in use for over 50 years and has proven very effective, particularly for bipolar disorder, type I. However, regular blood tests are required when taking lithium because of potential serious side effects to the kidneys and thyroid.

Newer mood stabilizers, many of which were originally used to treat seizure disorders, may work better than lithium for some people. Mood stabilizers can prevent manic or hypomanic episodes and depressive episodes. but also have side effects to know about and monitor.

Off-Label & Generic Medications

Some medications can be prescribed “off-label,” which means they haven’t been approved by the FDA for a given condition. A doctor should be clear about the limits of the research around off-label medication and always check for alternate options.

Be aware that generic medications and brand name medications are not exactly the same. The FDA requires only that generic medications contain the same active chemicals to those in brand name medications and that the route of administration—whether the medication is available as tablets, capsules, patches or injections—be identical.

Other characteristics may differ, like the inactive ingredients, color, flavor, fillers and binders. These inactive ingredients usually vary between drug companies and can influence the way a medication works for an individual. If you notice the look of the generic medication you are taking has changed, talk with your prescriber or pharmacist.
