👩🏽‍⚕️ Additional questions (FAQs)

💬 Are Doxepin capsules a type of sleeping pill?

This is not a real sleeping pill, this is an old-generation 'TCA - Tricyclic Antidepressant' (a powerful mental drug given for depression)! Doctors often use this for patients with severe depression and anxiety, to eliminate their fear and sadness and give them a sense of comfort.

💬 Why is this medicine (Doxepin) prescribed by the hospital for insomnia?

Although it is a drug for depression, doctors realized that when this drug is given in a 'low dose (brand name Silenor),' it blocks Histamine (a chemical that causes wakefulness) in the brain and causes unbearable sleepiness (sedation). Therefore, it is widely used in the world today for people who cannot sleep at night and wake up in the middle of the night (Sleep-maintenance insomnia), to get a good night's sleep without any addiction.

💬 Why do I get dry mouth/dizziness after taking these capsules (Doxepin)?

These are the biggest side effects of the old TCA drugs (Anticholinergic effects)! When these drugs change the chemicals in the brain, they also accidentally suppress the salivary glands in the body. As a result, you will have dry mouth/eyes, blurred vision, constipation, and postural hypotension, especially when you get out of bed in the morning.
