What is Lexapro (Escitalopram)?
Lexapro is the brand name for escitalopram, an antidepressant. Antidepressants help balance chemicals in the brain to improve mood. Lexapro is commonly prescribed for adults experiencing major depressive disorder or generalized anxiety disorder. It is available as a tablet taken orally.
Common Lexapro 20mg Side Effects
Side effects are possible with any medication, and Lexapro is no exception. Many side effects are mild and may go away as your body adjusts to the medicine. However, it’s important to be aware of them and talk to your doctor if they become bothersome.
Here are some of the more common side effects reported by people taking Lexapro:
- Nausea: Feeling sick to your stomach is a common initial side effect.
- Headache: Some people may experience headaches, especially when first starting Lexapro.
- Sleep disturbances: This can include insomnia (difficulty sleeping) or drowsiness.
- Sexual side effects: These can include decreased libido, delayed ejaculation, or difficulty achieving orgasm.
- Dry mouth: A decrease in saliva production can occur.
- Increased sweating: Some individuals may sweat more than usual.
- Constipation: Changes in bowel habits are possible.
Data from clinical trials show that these side effects are more likely to occur at the 20mg dosage of Lexapro.
Serious But Rare Lexapro Side Effects
Although less common, some serious side effects can occur while taking Lexapro. Seek immediate medical attention if you experience any of the following:
- Serotonin Syndrome: This is a rare but life-threatening condition caused by a buildup of serotonin in the body. Symptoms can include confusion, agitation, muscle stiffness, rapid heart rate, and seizures.
- Allergic Reactions: Some people may experience an allergic reaction to Lexapro. Signs include rash, itching, swelling, dizziness, or difficulty breathing.
- Unusual Bleeding or Bruising: Lexapro can affect blood clotting, so report any unusual bleeding or bruising to your doctor.
- Changes in Heart Rhythm: Lexapro can, in rare cases, affect the heart’s electrical activity. Seek immediate medical attention if you experience a fast or irregular heartbeat, dizziness, or fainting.
- Seizures: Though rare, seizures have been reported in some people taking Lexapro.
- Low Sodium Levels: Lexapro can sometimes cause the body to retain too much water, leading to low sodium levels in the blood. Elderly individuals may be more susceptible to this. Symptoms can include headache, confusion, weakness, muscle cramps, nausea, and vomiting.
Factors That Can Affect Side Effects
Several factors can influence the side effects you experience while taking Lexapro 20mg:
- Age: Older adults may be more sensitive to the effects of Lexapro and more prone to certain side effects.
- Other Medications: Drug interactions can increase the risk of side effects. Always tell your doctor about all the medications you are taking, including over-the-counter drugs and supplements.
- Underlying Health Conditions: Certain medical conditions, such as heart problems or liver problems, may increase the risk of side effects.
- Dosage: Higher doses of Lexapro, such as 20mg, may increase the likelihood and severity of side effects.
Managing Lexapro Side Effects
While you can’t always prevent side effects, there are steps you can take to manage them:
- Talk to Your Doctor: Report any side effects to your doctor. They may adjust your dosage or recommend ways to manage them.
- Stay Hydrated: Drinking plenty of water can help with dry mouth and constipation.
- Eat a Healthy Diet: A balanced diet can help with nausea and other gastrointestinal issues.
- Get Regular Exercise: Exercise can improve mood and help with sleep disturbances.
- Avoid Alcohol and Drugs: Alcohol and other drugs can worsen side effects and interact with Lexapro. If you find that the cost of medication is a barrier to your mental health treatment, explore options that can make your prescriptions more affordable.
Discontinuing Lexapro
It’s very important to never stop taking Lexapro abruptly. Suddenly stopping Lexapro can lead to withdrawal symptoms. Withdrawal symptoms can include flu-like symptoms, insomnia, nausea, dizziness, sensory disturbances, and anxiety. This is sometimes called “discontinuation syndrome.” To minimize these effects, your doctor will slowly lower your dose before you completely stop taking Lexapro.
