The Hidden Dangers of Taking Antidepressants Without Medical Guidance

Using antidepressants without a doctor's supervision can lead to severe complications such as seizures and even respiratory failure.

Understanding Depression

Feeling sad or down occasionally doesn't necessarily mean you have depression. Depression is a serious emotional disorder primarily caused by internal factors rather than external circumstances.

This diagnosis is made based on specific criteria, including:

• Persistent low mood;
• Reduced enjoyment in activities once found pleasurable;
• Increased fatigue, even after minimal physical activity.

These symptoms must be present most of the day for at least two weeks and do not disappear even after positive events like a promotion or receiving a desired gift.

Additional signs may include:

• Difficulty concentrating;
• Low self-confidence;
• Feelings of guilt over the illness;
• Loss of hope for the future;
• Sleep disturbances such as insomnia or difficulty waking;
• Appetite changes;
• Thoughts of self-harm.

Only a qualified psychiatrist or psychotherapist can evaluate these symptoms and provide an accurate diagnosis for several reasons.

Firstly, other disorders like bipolar disorder, schizophrenia, or dementia can mimic depression but require different treatments.

Secondly, some internal medical conditions, such as heart or endocrine diseases, can cause depression-like symptoms by reducing oxygen supply to the brain. This type of depression, called somatogenic depression, won’t improve without treating the underlying illness.

Lastly, atypical forms of depression exist, presenting symptoms like increased appetite and excessive sleepiness, which demand specialized treatment approaches.

How Antidepressants Work

Our emotions are regulated by chemical messengers called neurotransmitters, including:

• Norepinephrine – responsible for alertness, anxiety, and adaptation;
• Serotonin – regulates happiness, anxiety, aggression, sleep, and sexual behavior;
• Dopamine – triggers feelings of pleasure and reward;
• Oxytocin – promotes trust and reduces anxiety;
• Melatonin – controls sleep-wake cycles;
• Gamma-aminobutyric acid (GABA) – has a calming effect;
• Prolactin – involved in lactation and sexual response;
• Other neurotransmitters.

Many of these are hormones affecting not only mood but also bodily functions like reproductive health, blood pressure, and heart rate. Others, such as GABA and phenylethylamine, specifically influence emotions.

Most antidepressants target the first three neurotransmitters: norepinephrine, serotonin, and dopamine. They act at synapses—junctions between nerve cells—by modifying neurotransmitter levels to improve mood.

Neurons cannot simultaneously activate neurotransmitters that induce joy and those that cause depressive feelings. Antidepressants work by:

1. Inhibiting monoamine oxidase (MAO), the enzyme that breaks down neurotransmitters, allowing serotonin, norepinephrine, and dopamine to act longer. MAO inhibitors can be reversible or irreversible.
2. Blocking the reuptake of neurotransmitters, increasing their availability in the synaptic gap and enhancing their positive effects.
3. Stimulating the release of norepinephrine and serotonin, or serotonin alone, to boost 'happiness hormones.'

Another class of antidepressants targets neurons producing melatonin, addressing seasonal depression by increasing melatonin, dopamine, and norepinephrine levels while blocking certain serotonin receptors.

Herbal remedies like St. John's Wort extract also fall under antidepressants, as they inhibit the reuptake of dopamine, serotonin, and norepinephrine. Methionine-based supplements, involved in adrenaline synthesis, are also used.

Common Myths About Antidepressants Debunked

Myth: Antidepressants only mask problems instead of solving them

Antidepressants do not impair memory. Depression distorts problem perception and drains energy, making it hard to address issues. Medication helps restore mental clarity and energy to manage challenges effectively.

Myth: Antidepressants cause weight gain

While some antidepressants can increase weight, others like fluoxetine, sertraline, and escitalopram may reduce appetite and promote weight loss. Discuss any weight concerns with your healthcare provider.

Myth: Antidepressants must be taken for life

Treatment typically lasts 6 to 9 months, sometimes longer. Symptoms often resolve within this period, though over 20% of patients may experience recurrence.

Myth: Antidepressants negatively affect sexual potency

Some medications may lower libido but do not impair potency or orgasmic ability. In some cases, they may enhance sexual relationships by alleviating depressive symptoms.

Potential Risks of Antidepressant Use

According to medical regulations, antidepressants require a prescription due to their significant effects on the body's chemical balance, including hormones impacting multiple organs.

Common side effects include:

• Cardiovascular issues: increased heart rate, dizziness upon standing, fainting, shortness of breath;
• Endocrine disruptions: blood sugar fluctuations, unintended milk production in non-lactating women;
• Gastrointestinal problems: nausea, vomiting, appetite loss, abdominal pain, altered taste, tongue discoloration;
• Nervous system effects: insomnia, drowsiness, dizziness, tremors;
• Other effects: breast enlargement, hair loss, swollen lymph nodes, weight gain with prolonged use, skin or mucous membrane bleeding.

Antidepressants require precise dosing and are often incompatible with other medications and alcohol, which is prohibited during treatment lasting at least six months. Additionally, certain foods must be avoided, especially with MAO inhibitors, which can cause dangerous reactions if combined with tyramine-rich foods such as aged cheeses, smoked meats, dairy, broths, legumes, beets, sauerkraut, sausages, and organ meats.

Consuming these foods while on MAO inhibitors can trigger tyramine syndrome, characterized by sudden high blood pressure, severe headaches, facial flushing, chest pain, irregular heartbeat, light sensitivity, dizziness, and seizures.

Combining MAO inhibitors with other antidepressants that block neurotransmitter reuptake can cause severe side effects including fever, nausea, dizziness, and life-threatening seizures leading to respiratory arrest.

What to Do If You Suspect Depression

Depression causes profound emotional and physical suffering, reduces life quality, and can lead to disability due to loss of motivation and self-care ability. If untreated, suicidal thoughts may develop. Professional treatment is essential.

A psychiatrist or psychotherapist should oversee therapy. Mild to moderate cases, especially in children and adolescents, may respond well to psychotherapy, magnesium supplements, and increased physical activity without immediate medication.

Self-medication is strongly discouraged as it risks misdiagnosis and harmful side effects.
