Determining if you should take your antidepressant at night or in the morning depends on the specific medication you're taking, its side effects, and how it influences your quality of life. Your prescribing doctor may suggest a specific time of day for you to take your antidepressant to minimize any common adverse effects—primarily insomnia or drowsiness—that may be associated with your particular prescription.

Minimizing Insomnia

Some antidepressants—such as Celexa (citalopram), Zoloft (sertraline), and Effexor (venlafaxine)—have sustained-release formulations, and do not appear to be any more or less effective when taken at varying times of the day. However, some selective serotonin reuptake inhibitors (SSRIs), the class to which these medications belong, can disrupt sleep for some people and would be best taken in the morning.

For example, the manufacturer of Prozac (fluoxetine) recommends it be taken in the morning because it can make some people feel more energized, especially at the beginning of treatment. On the other hand, when Prozac is given in combination with Zyprexa (olanzapine)—a combination called Symbyax—as a therapy for treatment-resistant depression, it's recommended to be taken in the evening as it can cause sleepiness.

Paxil (paroxetine) is also generally taken in the morning in order to prevent sleeplessness at night. However, it may be given at bedtime if it is found to cause drowsiness in a particular patient when taken in the morning. Wellbutrin (bupropion) is another antidepressant that is recommended to be taken in the morning in order to prevent insomnia at night.

Minimizing Drowsiness

Unlike some SSRIs, certain other antidepressants tend to make you feel drowsy, so they're better tolerated if you take them at bedtime. Among these medications are Luvox (fluvoxamine), Remeron (mirtazapine), and the tricyclic antidepressants, including:

  • Elavil (amitriptyline)
  • Norpramin (desipramine)
  • Tofranil (imipramine)
  • Pamelor (nortriptyline)

Other Optimal Medication Strategies

In addition to discussing with your doctor the time of day that is best to take your antidepressant, it's critical to remember that there are other strategies that affect how well your medication will work, including:

  • Have patience. Antidepressants take time to work; potentially anywhere from 6 to 12 weeks for the full effect, although many people notice improvement within a week or two. When you start your antidepressant, keep in close touch with your doctor and stay positive—you can find a way to treat your condition, but it may take a little bit of trial and error.
  • Stay consistent. Take your antidepressant as directed at the same time every day and do not stop it without first talking to your doctor. If your antidepressant is causing side effects, remember that many, if not all of them, will go away with time. If the side effects are intolerable, get in touch with your doctor right away, as there is a solution, such as a dose change, switching to a different antidepressant, or adding a second medication to soothe the offensive side effect.

A Word From Verywell

Taking an antidepressant needs to be part of a well-thought-out plan with your doctor to maximize its benefits and minimize any potential side effects. Don't make any changes to your treatment plan without consulting with your doctor first; the recommendations noted above are general and may or may not be applicable to your own unique situation. Your doctor will be able to provide you with specific recommendations about whether your antidepressant should be taken at a particular time of day for the best results.
