Accidentally Took Two Lexapro? The Surprising Side Effects

Lexapro accidentally took 2 pills? If this describes your current situation, you are certainly not alone, as medication dosing mix-ups happen to the best of us. Whether you simply forgot you already took your daily dose, were distracted during your morning routine, or accidentally grabbed the wrong pill from your weekly organizer, realizing you’ve taken twice your prescribed amount of escitalopram can trigger immediate anxiety. However, before you rush straight to the emergency room, there are several crucial clinical factors you need to consider—and the first 24 hours are the most critical.

Quick Answer: What to Do If You Double Dose

If you accidentally took double dose of Lexapro (escitalopram), stay calm and immediately assess your current physical symptoms. For most adults on a standard therapeutic dose (for example, taking two 10mg pills instead of one for a total of 20mg, or taking two 20mg pills for a total of 40mg), a single accidental double dose is unlikely to cause severe or immediately life-threatening complications. You may, however, experience heightened, uncomfortable side effects such as moderate nausea, dizziness, daytime drowsiness, or a feeling of jitteriness. Regardless of how you feel, you should contact Poison Control (1-800-222-1222 in the US) or your primary healthcare provider to report the incident. Professional medical guidance is essential, especially if you are concurrently taking other medications.

What Happens If I Accidentally Take Two of My Escitalopram? Pharmacological Impact and Serotonin Saturation

If you are anxious and wondering what happens if i accidentally take two of my escitalopram (Lexapro / Cipralex), clinical pharmacology explains the acute physiological cascade:

• Serotonin Transporter (5-HTT) Saturation: Escitalopram is one of the most selective SSRIs available. Taking a double dose (e.g. two 10mg pills for 20mg total, or two 20mg pills for 40mg total) temporarily saturates your central serotonin reuptake transporters, triggering an acute surge in synaptic serotonin levels.
• Common Exaggerated Side Effects: Within 2 to 6 hours, you may experience gastrointestinal hypermotility (nausea, loose stools), mild dizziness, resting fatigue, fine hand tremors, or feeling nervous and restless.
• Understanding the 30-Hour Half-Life: Escitalopram has an elimination half-life of 27 to 32 hours. It takes approximately 24 hours for blood serum levels to drop back down to your usual steady-state therapeutic range.
• Differentiating Normal Side Effects from Serotonin Syndrome: While nausea and mild jitteriness are expected, true Serotonin Syndrome involves high fever, severe muscle rigidity or clonus (involuntary muscle jerks), and acute confusion. If these red flags appear, go to the emergency room immediately.
• Next-Day Protocol: Do not skip medications or induce vomiting. Drink plenty of water and resume your normal single prescribed dose at your next scheduled time.

Understanding Escitalopram and Serotonin Levels

Lexapro (the primary brand name for escitalopram, also known internationally by the brand name Cipralex) belongs to a heavily prescribed class of psychiatric medications called Selective Serotonin Reuptake Inhibitors (SSRIs). It works effectively by increasing the active levels of serotonin—a vital neurotransmitter—in the brain. This mechanism helps regulate mood, reduce anxiety symptoms, and improve overall sleep patterns. Because SSRIs directly alter your complex brain chemistry, taking an escitalopram overdose double dose suddenly spikes your serotonin levels well beyond what your central nervous system is accustomed to handling daily. This sudden, unexpected neurochemical surge is precisely what leads to the onset of adverse physical and mental side effects.

What Happens If You Take Too Much Cipralex or Lexapro?

When patients search for what happens if you take too much cipralex, the clinical answer largely depends on your normal daily prescribed dose, your body weight, your overall metabolic rate, and your general health history. Experiencing a double doasing lexipro event typically results in an uncomfortable exaggeration of the medication’s standard side effects rather than an acute medical emergency. Common symptoms to actively watch out for over the next 12 to 24 hours include:

• Gastrointestinal Distress: Nausea, vomiting, abdominal cramping, or sudden diarrhea.
• Neurological Symptoms: Dizziness, lightheadedness, excessive daytime drowsiness, insomnia at night, or mild hand tremors.
• Cardiovascular Changes: A slightly elevated resting heart rate (tachycardia) or subtle fluctuations in your blood pressure.
• Psychological Effects: Increased generalized anxiety, restlessness, agitation, or a feeling of being unusually “on edge.”

The Risk of Serotonin Syndrome

The most severe, albeit statistically rare, complication of what if i took 2 escitalopram by mistake is a potentially life-threatening toxic condition known as Serotonin Syndrome. This medical emergency occurs when serotonin levels become dangerously high in the central nervous system. Symptoms of Serotonin Syndrome require immediate emergency medical attention at a hospital and generally include:

• Severe confusion, disorientation, or delirium
• Dangerously rapid heart rate and elevated blood pressure
• Unusually dilated pupils that do not respond to light
• Loss of muscle coordination, muscle rigidity, or heavy twitching
• Heavy, unexplained sweating and shivering
• High fever without an underlying infectious cause

Frequently Asked Questions (FAQ)

Should I induce vomiting if I took a double dose?

No, you should never induce vomiting unless explicitly instructed to do so by a poison control center operator or an emergency medical professional. Inducing vomiting can cause aspiration and other dangerous complications, and is generally not the recommended first aid protocol for SSRI medication errors.

Do I skip my regular dose the next day?

Usually, you will resume your normal dosing schedule the following day, but you must strictly confirm this protocol with your prescribing doctor or local pharmacist. Do not alter, skip, or double up on your medication schedule without professional clinical guidance, as this can further destabilize your brain chemistry.

How long will the side effects of a double dose last?

The elimination half-life of Lexapro is approximately 27 to 32 hours. This means it takes well over a full day for half of the drug to naturally leave your system. Mild to moderate side effects from a double dose may last for 24 to 48 hours before fully subsiding.
