Selective serotonin reuptake inhibitors (SSRIs) are a type of drug that are used to treat various mental disorders including depression.
As they have been found to diminish experiences of moderate to severe depression, selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressants.
They are relatively safe and often lead to fewer side effects in comparison to other types of antidepressants that would be used for the same purpose.
How do SSRIs work?
SSRIs treat depression by increasing the amount of the chemical serotonin in the brain.
Serotonin is one of the chemical messengers (neurotransmitters) that deliver signals between brain nerve cells (neurons).
SSRIs hinder the reabsorption (reuptake) of serotonin into neurons.
This allows more serotonin to be available so that it can help facilitate the transmission of information and messages between neurons.
SSRIs are called selective because they mainly affect serotonin, not other neurotransmitters.
Aside from depression, SSRIs may also be used to treat other conditions such as anxiety disorders.
SSRIs approved to treat depression
The Food and Drug Administration (FDA) has approved these SSRIs to treat depression:
- Citalopram (Celexa)
- Escitalopram (Lexapro)
- Fluoxetine (Prozac)
- Paroxetine (Paxil, Pexeva)
- Sertraline (Zoloft)
What are possible side effects and cautions to be aware of before taking SSRIs?
Scientific research has found that all SSRIs have similar ways of functioning and usually can lead to similar side effects, which not all people experience in the first place.
After the first few weeks of beginning SSRI treatment, many of the potential side effects that you may experience will subside.
However, if the side effects persist you should notify your doctor and request to try a different drug to treat your malady.
SSRIs vary in their rate of blocking serotonin reuptake and how fast the body metabolizes the drug, so if you can’t tolerate one SSRI, your body still could respond positively to another SSRI that is different from the SSRI that you are unable to tolerate.
Among others, possible side effects of SSRIs may include:
- Nausea, vomiting or diarrhea
- Dry mouth
- Nervousness, agitation or restlessness
- Sexual problems, such as reduced sexual desire, difficulty reaching orgasm or inability to maintain an erection (erectile dysfunction)
- Impact on appetite, leading to weight loss or weight gain
To reduce your risk or experiences of nausea, try taking your medication with food.
Also, as long as your medication does not hinder your sleeping, you can minimize the effect of nausea by taking your SSRI when you head to bed.
Your symptoms and pre existing health conditions determine which antidepressant is best for you.
Ask your doctor and pharmacist about the most common possible side effects for your specific SSRI and fully read the patient medication guide that comes with the prescription.
Are there any safety issues I should know about before taking SSRIS?
Generally, SSRIs are safe for most people. However,they can cause problems for some people in certain circumstances.
For example, high doses of citalopram may cause dangerous abnormal heart rhythms, so doses over 40 milligrams (mg) a day should be avoided according to the FDA and the manufacturer.
They also recommend a maximum daily dose of 20 mg of citalopram for people over age 60.
Before deciding to begin treatment with an SSRI, talk with your doctor about:
- Drug interactions. When taking an antidepressant, tell your doctor about any other prescription or over-the-counter medications, herbs or other supplements you’re taking. Some antidepressants can interfere with the effectiveness of other medications, and some can cause dangerous reactions when combined with certain medications or herbal supplements.
For example, SSRIs may increase your risk of bleeding, especially when you’re taking other medications that increase the risk of bleeding, such as nonsteroidal anti-inflammatory drugs (NSAIDs), aspirin, warfarin (Coumadin, Jantoven) and other blood thinners.
- Serotonin syndrome. Rarely, an antidepressant can cause high levels of serotonin to accumulate in your body. Serotonin syndrome most often occurs when two medications that raise the level of serotonin are combined. These include, for example, other antidepressants, certain pain or headache medications, and the herbal supplement St. John’s wort.
Signs and symptoms of serotonin syndrome include anxiety, agitation, high fever, sweating, confusion, tremors, restlessness, lack of coordination, major changes in blood pressure and a rapid heart rate. Seek immediate medical attention if you have any of these signs or symptoms.
- Antidepressants and pregnancy. Talk to your doctor about the risks and benefits of using specific antidepressants. Some antidepressants may harm your baby if you take them during pregnancy or while you’re breast-feeding. If you’re taking an antidepressant and you’re considering getting pregnant, talk to your doctor about the possible risks. Don’t stop taking your medication without contacting your doctor first, as stopping might pose risks for you.
Suicide risk and antidepressants
The FDA requires that all antidepressants carry black box warnings, the strictest warnings for prescriptions, although most antidepressants are safe.
In some instances, children, teenagers and young adults under 25 may experience an increase in suicidal thoughts or behavior when on antidepressants, especially in the first few weeks after starting or when the dose is changed.
Anyone taking an antidepressant should be watched closely for worsening depression or unusual behavior.
If you or someone you know has suicidal thoughts when taking an antidepressant, immediately contact your doctor or get emergency help.
Keep in mind that antidepressants are more likely to reduce suicide risk in the long run by improving mood.
Stopping treatment with SSRIs
Luckily, SSRIs aren’t addictive. However, withdrawal-like symptoms can appear if one abruptly terminates antidepressant treatment abruptly or repeatedly misses several doses.
This phenomenon is sometimes called discontinuation syndrome. Work with your doctor to gradually and safely decrease your dose.
Withdrawal-like symptoms can include:
- General feeling of uneasiness
- Flu-like symptoms
How do I find the right antidepressant for me?
The same antidepressant may affect different people in different ways, causing varying reactions.
For example, a specific SSRI may work better — or not as well — for you than for another person.
Or you may have more, or fewer, side effects from taking a specific antidepressant than someone else does.
Genetically inherited traits also are a factor in how antidepressants affect you. If you have a close relative who had a negative experience using a particular antidepressant, tell your doctor, because this drug should be avoided.
Likewise, if you have a close relative who had a positive experience using a particular antidepressant, tell your doctor, because this drug could be a good starting point.
In some cases, results of special blood tests, if available, can offer clues about how your body may respond to a particular antidepressant.
However, other variables do affect your response to medication.
When deciding which antidepressant to take, your doctor should consider your symptoms, any health problems, other medications you take and what has worked for you in the past.
Often, it can take several weeks or longer before an antidepressant is fully effective and for initial side effects to halt.
Your doctor may recommend some dose adjustments or different antidepressants, but with patience, you and your doctor can find a medication that works well for you.
Who should take antidepressants?
If you suspect you have MDD, SAD, an anxiety disorder, or another related condition, talk to your doctor about taking antidepressants.
In addition, a loved one or friend may reach out to discuss these symptoms with you and point you in the direction of help.
These are debilitating mental health conditions and you should not feel like you have to go through them alone.
MDD is a mood disorder that causes feelings of worthlessness and loss of interest in daily activities. Common symptoms of MDD are as follows:
· Chronic feelings of sadness, tearfulness, emptiness, or hopelessness
· Loss of interest in activities that once used to bring enjoyment (i.e., sex, hobbies)
· Outbursts of anger
· Issues with sleeping too much or insomnia
· Lack of energy and fatigue
· Changes in eating patterns and weight (i.e., increased appetite and weight gain or reduced appetite and weight loss)
· Slowed speaking, thinking, and movement
· Feelings of worthlessness
· Ruminating on past failures
· Feelings of guilt
· Trouble concentrating, making proper decisions, and remembering things
· Physical problems such as back pain or headaches that cannot be explained by another medical condition
SAD is a subtype of depression that is heavily related to changes in seasons.
It usually begins at the same time every year and usually occurs during fall and winter months.
If you have any of the following symptoms, you may be diagnosed with SAD:
· Feelings of depression most of the day almost every day
· Low energy
· Loss of interest in activities that used to bring enjoyment
· Trouble sleeping, usually oversleeping
· Changes in appetite or weight
· Feelings of hopelessness, worthlessness, or guilt
· Feeling agitated or sluggish
· Frequent thoughts of death or suicide
In the winter months, people with SAD may frequently oversleep, gain weight due to food cravings high in carbohydrates, or have fatigue and lack of energy.
More rarely, people can suffer from SAD in the spring or summer months.
These patients are likely to experience trouble sleeping (insomnia), reduced appetite and weight loss, and agitation or anxiety.
