Celexa, also known by its generic name citalopram, is a medication commonly prescribed to treat depression and other mental health disorders. While it is generally well-tolerated, it can cause a range of side effects, including nausea, dry mouth, sleep changes, and sexual problems. Some people may experience muscle twitching, jerking, spasms, or tremors while taking Celexa. However, it is unclear if a dosage of 40 mg can cause muscle weakness specifically. It is important to consult a doctor or healthcare provider to discuss any concerns or side effects experienced while taking Celexa, as they may recommend adjustments or alternative treatments.

What You'll Learn
Muscle twitching, tremors, and spasms
Citalopram, the active ingredient in Celexa, can cause muscle twitching, tremors, and spasms in some people. These side effects can occur when carrying out precise movements, such as pouring a liquid or crocheting, or when trying to fall asleep. They can also be felt under the eye, in the stomach, or in the arms and legs.
Muscle twitching and spasms are commonly reported side effects of Celexa, with some users experiencing these symptoms for several months after starting the medication. These side effects can be mild or severe and may be more frequent when resting or relaxing. In some cases, muscle twitching and spasms may be accompanied by other symptoms, such as a blocked throat, dry mouth, or sore throat.
It is important to note that the side effects of Celexa typically occur most frequently in the first 1 to 2 weeks of therapy and then attenuate subsequently. However, in some cases, muscle twitching and spasms may persist for longer periods. If you are experiencing these side effects, it is recommended to consult your doctor or healthcare provider for advice and to explore alternative treatment options if necessary.
While muscle twitching, tremors, and spasms are known side effects of Celexa, they are not the only possible causes of these symptoms. It is important to consider other factors, such as anxiety, which can also contribute to muscle twitching and spasms. Additionally, underlying medical conditions or other medications can play a role in these symptoms. Therefore, it is always advisable to seek professional medical advice if you are concerned about any new or persistent symptoms.

Heart rhythm abnormalities
Celexa, also known as citalopram, is an antidepressant in the selective serotonin reuptake inhibitor (SSRI) class. It is used to treat depression and, sometimes, alcoholism, panic disorder, premenstrual dysphoric disorder, social phobia, or eating disorders.
Celexa has been associated with abnormal heart rhythms at high doses. The U.S. Food and Drug Administration (FDA) has issued a Drug Safety Communication (DSC) stating that Celexa should not be used at doses greater than 40 mg per day because it could cause potentially dangerous abnormalities in the electrical activity of the heart. This change in electrical activity is known as prolongation of the QT interval of the electrocardiogram (ECG) and can lead to an abnormal heart rhythm called Torsade de Pointes, which can be fatal. Patients with underlying heart conditions and those with low levels of potassium and magnesium in the blood are at particular risk for developing prolongation of the QT interval.
A European study linked citalopram with increased electrical abnormalities of the heart and found that these abnormalities worsened with increasing doses. The FDA has received reports of QT interval prolongation and Torsade de Pointes associated with Celexa and its generic equivalents. As a result, the citalopram drug label has been revised to include warnings about the potential for QT interval prolongation and Torsade de Pointes, as well as new drug dosage and usage recommendations.
If you are taking citalopram and experience signs or symptoms of an abnormal heart rate or rhythm, such as dizziness, palpitations, or syncope, you should contact a healthcare professional immediately. Do not stop taking citalopram or change your dose without first consulting your healthcare provider, as stopping citalopram suddenly can cause unwanted side effects.

Suicidal thoughts
Celexa (citalopram) is a brand-name drug used to treat depression in adults. It is also sometimes used to treat obsessive-compulsive disorder, eating disorders, alcoholism, panic disorder, premenstrual dysphoric disorder, social anxiety disorder, post-traumatic stress disorder, and certain male sexual problems.
Celexa has a boxed warning for the risk of suicidal thoughts and behaviours in children and young adults (aged 18-24 years). This is the most serious warning from the Food and Drug Administration (FDA). The risk is highest during the first few months of treatment and after any dosage changes. If you or someone you know is experiencing suicidal thoughts or behaviours while taking Celexa, it is important to seek immediate medical attention.
It is important to note that having depression or another mental illness increases the risk of becoming suicidal. This risk is higher if you or anyone in your family has a history of bipolar disorder, mania, or suicidal thoughts or attempts. Before taking Celexa or any other antidepressant, it is crucial to discuss the risks and benefits with a doctor or mental health professional.
While Celexa can be effective in treating depression, it is not suitable for everyone. Some people may experience side effects, including muscle pain and fatigue. It is recommended to start with a low dosage and gradually increase it under the supervision of a doctor.

Serotonin syndrome
While serotonin syndrome can be caused by taking just one drug that increases serotonin levels, it most often occurs when combining certain medications or drugs. For example, it may occur when taking an antidepressant with a migraine or opioid pain medication. It can also be caused by an intentional overdose of antidepressant medication. Antidepressants are the most commonly used medications that affect serotonin levels. Other causes include taking herbal supplements, certain illegal drugs, or over-the-counter drugs that affect serotonin levels.
The symptoms of serotonin syndrome vary from mild to severe and can include:
- Nervousness
- Nausea and vomiting
- Dilated pupils
- Agitation and restlessness
- Muscle twitching, involuntary muscle contractions, muscle spasms, and rigidity
- Sweating and shivering
- Abnormal (side-to-side) eye movements
- Confusion, disorientation, and delirium
- Fast heartbeat
- Hallucinations
- Severe dizziness
- Loss of physical coordination
- Seizures
- High fever
If you suspect you have serotonin syndrome, seek immediate medical attention as it can be life-threatening. Stopping the drug(s) or medication(s) causing serotonin syndrome is the main treatment.

Sexual side effects
Celexa (citalopram) is an antidepressant in the selective serotonin reuptake inhibitor (SSRI) class. It is used to treat depression and sometimes prescribed for alcoholism, panic disorder, premenstrual dysphoric disorder, social phobia, or eating disorders.
Like other antidepressants, Celexa may cause sexual side effects in both men and women. These sexual side effects are uncommon, and they can usually be treated by making changes to the medication. For example, a doctor may recommend a change in dosage, timing for taking the medication, or switching to a different medication.
- Reduced sex drive
- Delayed orgasm or anorgasmia (inability to achieve orgasm)
- Reduced sex drive
- Delayed ejaculation or anorgasmia
- Erectile dysfunction (ED)
These sexual side effects may fade after the body adjusts to the medication, but others may persist for as long as a person takes the medication. In some cases, people may experience a long-term condition called post-SSRI sexual dysfunction even after stopping SSRIs such as Celexa.
It is important to speak to a healthcare provider about any changes in sexual functioning after starting Celexa. They can offer strategies for avoiding or reducing these effects early in the treatment.
