Lexapro, the brand name for escitalopram, is a widely prescribed selective serotonin reuptake inhibitor (SSRI) used to treat major depressive disorder and generalized anxiety disorder. While often effective, its use requires adherence to specific precautions to avoid dangerous side effects and reduce its efficacy. Ignoring these guidelines can lead to serious health complications, from serotonin syndrome to increased bleeding risk.
Critical Drug Interactions to Avoid on Lexapro
Mixing Lexapro with certain substances can be extremely dangerous. A primary concern is Serotonin Syndrome, a potentially life-threatening condition caused by an excess of serotonin in the brain.
Monoamine Oxidase Inhibitors (MAOIs)
This is a major contraindication. You must not take Lexapro within 14 days of taking an MAOI, and you must not start an MAOI within 14 days of stopping Lexapro. The combination can cause a dangerous spike in serotonin levels. MAOIs include medications like isocarboxazid, phenelzine, and tranylcypromine, as well as linezolid (an antibiotic) and intravenous methylene blue.
Other Serotonergic Medications
Combining Lexapro with other drugs that increase serotonin also raises the risk of Serotonin Syndrome. These include:
- Other antidepressants: Including other SSRIs, SNRIs (serotonin and norepinephrine reuptake inhibitors), and tricyclic antidepressants.
- Triptans: Used for migraine headaches, such as sumatriptan.
- Opioid medications: Certain opioids like tramadol and fentanyl can increase serotonin.
- Lithium: A mood-stabilizing medication.
- Amphetamines: Used for conditions like ADHD.
Pimozide
This antipsychotic drug is used for Tourette syndrome and should never be taken with Lexapro. The combination can lead to a heart rhythm issue called prolonged QT interval, which can be life-threatening.
Alcohol and Lexapro: A Risky Combination
Healthcare providers strongly advise against drinking alcohol while taking Lexapro, even in small amounts. While clinical trials have not shown that Lexapro enhances alcohol's effects, the combination can worsen side effects and counteract the medication's benefits.
Worsened side effects
Both Lexapro and alcohol can cause dizziness and drowsiness. Taking them together can significantly amplify these effects, leading to impaired coordination and judgment.
Reduced effectiveness
Alcohol is a depressant and can worsen symptoms of depression and anxiety, which is counterproductive to the purpose of taking Lexapro. It can also interfere with how the liver processes the medication, affecting its efficacy.
Other risks
Mixing these substances can increase the risk of liver damage, alcohol dependence, and, critically, suicidal thoughts or behaviors.
Important Lifestyle and Behavioral Precautions
Do not stop taking Lexapro abruptly
Suddenly stopping Lexapro can lead to withdrawal symptoms, also known as antidepressant discontinuation syndrome. Symptoms can include dizziness, nausea, headaches, agitation, irritability, mood swings, and "brain zaps" (electric shock-like sensations). Always work with your doctor to gradually taper your dose if you need to stop.
Avoid driving until you know how you react
Lexapro can cause drowsiness, dizziness, and impaired judgment, especially when you first start taking it or after a dose change. Avoid driving or operating heavy machinery until you understand how the medication affects your alertness and coordination.
Carefully monitor your mood and behavior
In young adults (under 25), antidepressants like Lexapro may increase the risk of suicidal thoughts and behaviors, especially early in treatment or after a dosage change. Patients of all ages should be closely monitored for worsening depression, mood changes, or unusual behavior.
Who Should Exercise Extra Caution?
Certain pre-existing conditions warrant extra caution or may be contraindications for taking Lexapro. It is vital to discuss your full medical history with your doctor before starting this medication.
- Bipolar disorder: Lexapro can trigger a manic episode in individuals with bipolar disorder. Patients with a family history of bipolar disorder should be screened before starting treatment.
- Bleeding problems: Individuals with bleeding disorders or those taking blood thinners are at an increased risk of bleeding or bruising when taking Lexapro.
- Glaucoma: Lexapro can cause the pupils to dilate, which can trigger an angle-closure glaucoma attack in people with narrow-angle glaucoma. An eye exam may be recommended before starting treatment.
- Seizure conditions: People with a history of seizures are at a higher risk of having seizures while on Lexapro.
- Liver or kidney problems: These conditions can affect how your body processes Lexapro. Your doctor may need to adjust your dosage.
Lexapro Drug Interaction Comparison
| Interaction Category | Examples | Risk | Recommendation |
|---|---|---|---|
| Monoamine Oxidase Inhibitors (MAOIs) | Isocarboxazid, phenelzine, linezolid | High risk of Serotonin Syndrome | Avoid taking within 14 days of each other |
| Alcohol | Beer, wine, spirits | Worsened drowsiness, depression, liver issues | Avoid completely |
| Blood Thinners (Anticoagulants/NSAIDs) | Warfarin, ibuprofen, aspirin | Increased bleeding risk | Consult doctor; monitor for signs of bleeding |
| Other Serotonergic Drugs | Triptans, Tramadol, Lithium, St. John's Wort | Risk of Serotonin Syndrome | Inform your doctor about all medications and supplements |
What to Do If You Experience Adverse Effects
It is important to recognize the signs of serious side effects that require immediate medical attention. Seek emergency care if you experience symptoms of:
- Serotonin Syndrome: Agitation, hallucinations, rapid heartbeat, fever, muscle rigidity, nausea, or vomiting.
- Severe Allergic Reaction: Swelling of the face, lips, or tongue; difficulty breathing; rash or hives.
- Mania: Racing thoughts, unusual risk-taking behavior, or extreme happiness or irritability.
- Glaucoma Attack: Eye pain, sudden vision changes, seeing halos around lights, or nausea.
- Abnormal Bleeding: Unusual bruising, nosebleeds, or blood in stool.
Conclusion
Taking Lexapro can be a crucial step in managing depression and anxiety, but it comes with critical precautions. You should not mix it with alcohol or certain medications, such as MAOIs, due to severe interaction risks like Serotonin Syndrome. Never stop taking Lexapro suddenly, and avoid driving until you know how it affects your alertness. Special care is required for individuals with pre-existing conditions like bipolar disorder, glaucoma, or bleeding disorders. By communicating openly with your healthcare provider and adhering to these warnings, you can maximize the benefits of Lexapro while minimizing potential harm.
