Can the medication you take be life-threatening? Let's talk about Serotonin Syndrome

Are you someone who takes medication for depression, migraines, or severe pain? Or do you take medication from several doctors for the same illness? Then this story will be very important for you. Today we are talking about a condition that can occur in our body due to certain types of medications, which can be life-threatening if not properly understood. We call this 'Serotonin Syndrome' . Don't worry, if we know about this properly, we can avoid a big risk.

Simply put, what is Serotonin Syndrome?

To understand this, we first need to know what 'Serotonin' is. Think of it as a little messenger that carries messages between our brain and the rest of our body. In medicine, we call these chemical messengers 'neurotransmitters'. Serotonin is also a very important neurotransmitter for our body, controlling many things like our mood, sleep, and appetite.

Normally, when you take the medicine prescribed by a doctor, the level of serotonin in the body is balanced. However, if for some reason this chemical called serotonin increases too much in our body , that is, if it accumulates in an amount that the body cannot handle, the reaction of our body to it is called 'serotonin syndrome'. This can be a dangerous reaction caused by a type of medicine (drug reaction).

Who is more likely to develop this condition?

In fact, anyone of any age who uses medications, supplements, or illegal drugs that affect serotonin levels is at risk. This condition is most commonly seen in situations like these:

• When starting a new medication: As soon as you start a new medication that increases serotonin levels.
• When increasing the dose of a medication: If your doctor increases the dose of a medication you are already taking.
• When using several medications together: This is the most dangerous and common cause. Imagine, you have a joint ache. You take a painkiller from one doctor for it. In the meantime, because you are a little worried, you see another doctor and take medicine for that too. But you do not tell the first doctor about the second medicine, nor the second doctor about the first medicine. This is when there is a high chance of unknowingly using two serotonin-boosting drugs together and causing this situation.
• If you take too much medicine: If you take more medicine than the prescribed dose, intentionally or accidentally.

What are the symptoms? How do we recognize this?

The symptoms of serotonin syndrome can vary from person to person. Some people may experience very mild symptoms, while others may experience severe, life-threatening symptoms. These symptoms usually begin within a few hours of taking a new medication or changing the dosage.

For ease of understanding, let's divide these symptoms into three categories.

What are these medications that increase serotonin levels?

This list is a bit long, but it's very important for your safety to be aware of this.

Antidepressants

These are the medications most commonly associated with serotonin syndrome. The risk is especially high when these are taken with other medications (e.g., migraine medications).

• SSRIs (Selective serotonin reuptake inhibitors): Medications like Fluoxetine, Sertraline, Citalopram, Escitalopram, Paroxetine.
• SNRIs (Serotonin-norepinephrine reuptake inhibitors): Medications like Venlafaxine, Duloxetine, Desvenlafaxine.
• Tricyclic antidepressants: Medications like Amitriptyline, Nortriptyline, Imipramine.
• MAOIs (Monoamine oxidase inhibitors): Although these are not commonly used anymore, they are given in some cases.

Other medications

• Medications for severe pain: Painkillers like Tramadol, Pethidine (Meperidine), Fentanyl, and Methadone.
• Cough medicine: Some cough syrups available from pharmacies contain a substance called Dextromethorphan . This can also affect serotonin levels.
• Migraine medications: Triptan medications such as Sumatriptan and Rizatriptan.
• Medicines for vomiting: Medicines like Metoclopramide and Ondansetron.
• Some antibiotics: The antibiotic linezolid.
• Mood control medication: Lithium.

Other things

• Herbal supplements: Things like St. John's wort and Ginseng.
• Illegal drugs: Things like Ecstasy (MDMA), LSD, Cocaine, Amphetamines.

Don't be alarmed by this list. Not everyone will develop this condition after taking one of these medications. The risk only arises when you use several of these together, increase the dosage, or if your body is sensitive to them.

How does a doctor recognize this?

There is no specific blood test or scan to confirm serotonin syndrome. A doctor will diagnose the condition based on several factors:

1. Your symptoms: Listen carefully to what you are feeling.

2. Physical examination: Your heart rate, blood pressure, body temperature, and muscle condition will be checked.

3. List of medications you are taking: This is the most important thing.

In addition, you may also have blood and urine tests, a chest X-ray, or a CT scan to make sure you don't have other conditions (e.g., infections) that are causing similar symptoms.

What are the treatments for this?

Treatment depends on the severity of your symptoms.

• If you have mild symptoms: The usual treatment is to stop taking the medication that caused the symptoms. This will usually resolve the symptoms completely within 24-72 hours.
• If you have moderate symptoms: You will be kept in the hospital and observed for at least 24 hours. During this time, you will be given saline (IV fluids) and medications such as benzodiazepines for anxiety.
• If you have severe symptoms: This is a medical emergency. You will be admitted to the intensive care unit (ICU) and given treatment such as support for breathing difficulties, control of high fever, and medication to control heart rate and blood pressure. Sometimes, a medication called Cyproheptadine, which blocks the action of serotonin, may also be given.

How can we protect ourselves from this situation?

There are a few simple, yet very important things we can do to stay safe from this dangerous situation.

1. Educate yourself about your medications: Keep a record of the name, dosage, and purpose of every medication you take.

2. Tell each doctor the full details: If you are being treated by several doctors, be sure to tell one doctor about the medications prescribed by the others.

3. Don't stop taking medication without asking your doctor: Even if you feel any discomfort, don't stop taking medication or change the dosage without talking to a doctor.

4. Be careful when buying medicine from the pharmacy: When buying medicine for things like coughs and colds, ask for a medicine that is compatible with the medicine you are already taking.

5. Pay attention to symptoms: Pay close attention to any changes in your body, especially when starting a new medication or increasing the dosage.
