How to Take Citalopram: Administration Instructions

Swallow the tablet whole with water; do not crush or chew it. If you are using the oral solution, measure the dose carefully with a dosing syringe or cup. Do not stop taking Citalopram abruptly without consulting your healthcare provider, as this can lead to withdrawal symptoms. If you have any concerns or experience side effects, contact your doctor or schedule a telemedicine appointment with one of our providers.

Citalopram Side Effects and Adverse Reactions

Like all medications, Citalopram may cause side effects. Most are mild and tend to resolve on their own, but some may require medical attention. If you experience any severe side effects, contact your healthcare provider immediately.

Common Citalopram Side Effects (Occurring in more than 10% of patients)

Nausea: A feeling of sickness in the stomach, which may improve over time.

Dry mouth: A reduction in saliva that can make your mouth feel dry.

Fatigue: Feeling unusually tired or lacking energy.

Insomnia: Difficulty falling asleep or staying asleep.

Less Common Citalopram Side Effects (Occurring in 1-10% of patients)

Dizziness: Feeling lightheaded or unsteady.

Increased sweating: Excessive sweating, especially at night.

Diarrhea: Loose or watery stools.

Sexual dysfunction: Reduced interest in sex or difficulty achieving orgasm.

Rare but Serious Citalopram Side Effects (Occurring in less than 1% of patients)

Serotonin syndrome: A potentially life-threatening condition that can cause confusion, rapid heart rate, and high blood pressure.

Severe allergic reactions: Symptoms may include rash, itching, swelling, or difficulty breathing.

Suicidal thoughts or behavior: Citalopram may increase the risk of suicidal thoughts, particularly in young adults. Contact your healthcare provider immediately if you experience these symptoms.

Contraindications for Citalopram Use

A contraindication is a specific condition or situation where a medication should not be used because it may cause harm. If you have any of the following conditions, you should not take Citalopram unless your healthcare provider advises otherwise.

Allergy to Citalopram or similar medications: If you have had an allergic reaction to Citalopram or other SSRIs, taking this medication could cause serious allergic reactions, including rash, swelling, or difficulty breathing.

Use of Monoamine Oxidase Inhibitors (MAOIs): Citalopram should not be taken if you are currently using or have recently used MAOIs (such as phenelzine or tranylcypromine). Combining these medications can lead to a dangerous condition called serotonin syndrome, which can be life-threatening.

Congenital Long QT Syndrome: This heart condition can cause irregular heartbeats, and Citalopram may increase the risk of serious heart rhythm problems in people with this syndrome.

Uncontrolled electrolyte imbalances: Low levels of potassium or magnesium in your blood can increase the risk of heart problems when taking Citalopram.

Severe liver or kidney disease: If you have severe liver or kidney problems, your body may not process Citalopram properly, leading to higher levels of the drug in your system and increasing the risk of side effects.

Drug to Drug Interactions

Citalopram can interact with other medications, potentially increasing side effects or reducing its effectiveness. It’s important to inform your healthcare provider about all the medications you are taking, including over-the-counter drugs and supplements. Some key interactions include:

1. Monoamine Oxidase Inhibitors (MAOIs): (e.g., Nardil [phenelzine], Parnate [tranylcypromine]) – Combining these with Citalopram can lead to serotonin syndrome, a potentially life-threatening condition.
2. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): (e.g., Advil [ibuprofen], Aleve [naproxen]) – These may increase the risk of bleeding when taken with Citalopram.
3. Blood thinners: (e.g., Coumadin [warfarin], Plavix [clopidogrel]) – Citalopram may heighten the risk of bleeding when combined with these medications.
4. Other SSRIs or SNRIs: (e.g., Prozac [fluoxetine], Zoloft [sertraline], Cymbalta [duloxetine]) – Taking multiple antidepressants can increase the risk of serotonin syndrome.
5. Triptans: (e.g., Imitrex [sumatriptan]) – These migraine medications can raise the risk of serotonin syndrome when combined with Citalopram.

Citalopram in Pregnancy

Is it Safe to Take Citalopram During Pregnancy?

Taking Citalopram during pregnancy requires careful consideration. Untreated depression poses risks to both the mother and baby, but Citalopram may also carry risks, particularly in the third trimester. Some studies suggest that babies exposed to SSRIs like Citalopram late in pregnancy may experience withdrawal symptoms or breathing difficulties after birth. However, untreated depression can also have significant consequences. It’s essential to discuss the potential benefits and risks with your healthcare provider. If you are pregnant or planning to become pregnant, our telemedicine providers can help you make an informed decision about your treatment options.

Citalopram While Breastfeeding

Is it Safe to Take Citalopram While Breastfeeding?

Citalopram passes into breast milk in small amounts. While most studies suggest the risk to a breastfeeding infant is low, some babies may experience side effects such as irritability or feeding difficulties. If you are breastfeeding or planning to breastfeed, it’s important to discuss the risks and benefits with your healthcare provider. In some cases, alternative treatments may be recommended. Our telemedicine providers are available to help you navigate these decisions and find the best treatment plan for you and your baby.

Estimated Cost of Citalopram

The cost of a 30-day supply of Citalopram can vary depending on the pharmacy and location. Using a GoodRx coupon, the estimated cost for a 30-day supply of generic Citalopram (20 mg) ranges from $4 to $10 without insurance.

Possible Alternatives to Citalopram

If Citalopram is not suitable for you, other medications and lifestyle changes may help manage your condition. Always consult your healthcare provider before making any changes to your treatment plan. Our telemedicine providers can help you explore these options.

1. Depression: Alternatives include other SSRIs (e.g., Zoloft [sertraline]), serotonin-norepinephrine reuptake inhibitors (SNRIs) like Cymbalta (duloxetine), or cognitive-behavioral therapy (CBT). Lifestyle changes such as regular exercise, a balanced diet, and mindfulness practices can also support mental health.
2. Anxiety disorders (generalized anxiety disorder, social anxiety disorder, panic disorder): Alternatives include benzodiazepines (e.g., Xanax [alprazolam]), SNRIs, or beta-blockers (e.g., Inderal [propranolol]). Cognitive-behavioral therapy (CBT) and relaxation techniques, such as deep breathing and meditation, can also be helpful.
3. Obsessive-compulsive disorder (OCD): Other SSRIs (e.g., Prozac [fluoxetine]) or tricyclic antidepressants (e.g., Anafranil [clomipramine]) may be alternatives. Behavioral therapy, especially exposure and response prevention (ERP), is also effective.
4. Post-traumatic stress disorder (PTSD): Alternatives include SNRIs, other SSRIs, or psychotherapy, such as trauma-focused cognitive-behavioral therapy (CBT) or eye movement desensitization and reprocessing (EMDR).
5. Premenstrual dysphoric disorder (PMDD): Other SSRIs or hormonal treatments (e.g., birth control pills) may be considered. Lifestyle changes, such as regular exercise and stress management, can also help manage symptoms.
6. Chronic pain syndrome: SNRIs (e.g., Cymbalta [duloxetine]) or tricyclic antidepressants (e.g., Elavil [amitriptyline]) may be alternatives. Physical therapy, acupuncture, and mindfulness-based stress reduction (MBSR) can also help manage chronic pain.
7. Eating disorders: Treatment may include other SSRIs, such as Prozac (fluoxetine), or psychotherapy, such as cognitive-behavioral therapy (CBT). Nutritional counseling and support groups are also important components of treatment.

Recent Updates on Citalopram Research

Recent studies have explored the long-term effects of Citalopram and other SSRIs, particularly their impact on cognitive function and emotional regulation. Some research suggests that SSRIs may improve cognitive function in patients with depression. Other studies are investigating the benefits of combining Citalopram with therapies like cognitive-behavioral therapy (CBT) to enhance treatment outcomes. Additionally, ongoing research examines Citalopram’s role in treating conditions beyond depression, such as chronic pain and certain anxiety disorders. Stay informed and discuss any updates with your healthcare provider. Our telemedicine providers are available to help you understand how the latest research may impact your treatment plan.
