Celexa Side Effects

Celexa Side Effects

Celexa is a commonly prescribed medication used to treat depression and anxiety disorders. It belongs to a class of drugs known as selective serotonin reuptake inhibitors (SSRIs), which work by increasing the level of serotonin in the brain.

While Celexa is generally considered safe and effective, like any medication, it can cause side effects. In this blog post, we will discuss the common and rare side effects of Celexa.

Common Side Effects of Celexa

The most common side effects of Celexa include:

  1. Nausea: Some people may experience nausea and vomiting, especially when they take Celexa for the first time.
  2. Dry Mouth: Celexa can cause a decrease in saliva production, leading to a dry mouth.
  3. Drowsiness: Celexa can cause drowsiness and fatigue, which can affect a person’s ability to perform daily activities.
  4. Insomnia: Some people may experience difficulty falling or staying asleep.
  5. Headaches: Celexa may cause headaches in some people.
  6. Dizziness: Celexa can cause dizziness and lightheadedness.
  7. Sexual Dysfunction: Celexa can cause sexual side effects, such as decreased libido, difficulty achieving orgasm, and erectile dysfunction.

Note: These side effects are usually mild and temporary, and they often improve as the body adjusts to the medication. If they persist or become bothersome, talk to a healthcare provider.

Rare Side Effects

Some people may experience more serious side effects when taking Celexa. These may include:

  1. Suicidal Thoughts: In rare cases, Celexa may increase the risk of suicidal thoughts or behavior, particularly in young adults under the age of 25.
  2. Serotonin Syndrome: Celexa can increase the levels of serotonin in the brain, which can lead to a potentially life-threatening condition called serotonin syndrome. Symptoms of serotonin syndrome include agitation, confusion, rapid heartbeat, high blood pressure, and fever.
  3. Abnormal Bleeding: Celexa can interfere with blood clotting, which can increase the risk of bleeding. This may manifest as easy bruising or bleeding, particularly in people taking blood thinners.
  4. Mania: In some people, Celexa may trigger manic episodes, characterized by excessive excitement, energy, and impulsivity.
  5. Seizures: Celexa can lower the seizure threshold, which can increase the risk of seizures, particularly in people with a history of seizures or epilepsy.



Celexa is an effective medication for the treatment of depression and anxiety disorders. While the majority of people who take Celexa do not experience any serious side effects, it’s important to be aware of the potential risks.

If you experience any side effects, it’s important to talk to a healthcare provider. If you experience any serious or life-threatening side effects, seek medical attention immediately.
