This means that this type of medication is also commonly used for depression, but when used for insomnia, it is often given in very low doses . In Sri Lanka, you may find this medication under the brand name Silenor.

Also, it's important to know that doctors may sometimes prescribe this medication for other conditions as well. So if you're not sure why you've been prescribed this medication, it's best to ask your doctor or pharmacist.

What are the things I need to tell the doctor before taking this medicine?

Before you start taking Doxepin, there are a few things you should definitely tell your doctor. This is because this medication may not be suitable for people with certain medical conditions, or may need to be used with special care.

👩🏽‍⚕️ Additional questions (FAQs)

💬 Are Doxepin pills really a sleeping pill or a drug for depression?

This (TCA) is actually a powerful medicine given for 'Depression/Anxiety' of the old generation! But doctors later realized that when given in small amounts (Low dose - 3mg/6mg), it blocks Histamine (a chemical that keeps you awake) in the brain and brings about an unbearable sleep (Sedative effect). Therefore, nowadays, it is prescribed very successfully for 'Insomnia' even for those who do not have depression.

💬 Why does this pill (Doxepin) make my mouth dry after I fall asleep?

This is the biggest side effect of the old TCA drugs (Anticholinergic side effects)! In addition to making you sleepy, it also has a slight effect on other nervous systems in our body. This can cause dry mouth/eyes, blurred vision, and sometimes even stomach upset. It can also make you feel dizzy when you wake up in the morning.

💬 Is Doxepin addictive like sleeping pills?

No! This is the biggest advantage of this medicine. When you continue to take regular sleeping pills (Benzodiazepines / Valium), your body becomes addicted to them and then you can't sleep without the pills. But Doxepin is a non-habit forming medicine! Therefore, you can use it for months without any fear, even under medical advice, to get a sound sleep.
