Mirtazapine Insomnia Causes and Reviews


What is Insomnia?

Insomnia is a common sleep disorder. If you have it, you may have trouble falling asleep, staying asleep, or both. As a result, you may get too little sleep or have poor-quality sleep. You may not feel refreshed when you wake up.

What are the symptoms of Insomnia?

Symptoms of Insomnia include:

  • Lying awake for a long time before you fall asleep
  • Sleeping for only short periods
  • Being awake for much of the night
  • Feeling as if you haven't slept at all
  • Waking up too early
What are the types of Insomnia?

Insomnia can be acute (short-term) or chronic (ongoing). Acute Insomnia is common. Common causes include stress at work, family pressures, or a traumatic event. It usually lasts for days or weeks.

Chronic Insomnia lasts for a month or longer. Most cases of chronic Insomnia are secondary. This means they are the symptom or side effect of some other problem, such as certain medical conditions, medicines, and other sleep disorders. Substances such as caffeine, tobacco, and alcohol can also be a cause.

Sometimes chronic Insomnia is the primary problem. This means that it is not caused by something else. Its cause is not well understood, but long-lasting stress, emotional upset, travel and shift work can be factors. Primary Insomnia usually lasts more than one month.

Who gets Insomnia?

Insomnia is common. It affects women more often than men. You can get it at any age, but older adults are more likely to have it. You are also at higher risk of Insomnia if you

  • Have a lot of stress
  • Are depressed or have other emotional distress, such as divorce or death of a spouse
  • Have a lower income
  • Work at night or have frequent major shifts in your work hours
  • Travel long distances with time changes
  • Have an inactive lifestyle
  • Are African American; research shows that African Americans take longer to fall asleep, don't sleep as well, and have more sleep-related breathing problems than whites.
What other problems can Insomnia cause?

Insomnia can cause daytime sleepiness and a lack of energy. It also can make you feel anxious, depressed, or irritable. You may have trouble focusing on tasks, paying attention, learning, and remembering. Insomnia also can cause other serious problems. For example, it could make you may feel drowsy while driving. This could cause you get into a car accident.

How is Insomnia diagnosed?

To diagnose Insomnia, your health care provider

  • Takes your medical history
  • Asks for your sleep history. Your provider will ask you for details about your sleep habits.
  • Does a physical exam, to rule out other medical problems that might cause Insomnia
  • May recommend a sleep study. A sleep study measures how well you sleep and how your body responds to sleep problems.
What are the treatments for Insomnia?

Treatments include lifestyle changes, counseling, and medicines:

  • Lifestyle changes, including good sleep habits, often help relieve acute (short-term) Insomnia. These changes might make it easier for you to fall asleep and stay asleep.
  • A type of counseling called cognitive-behavioral therapy (CBT) can help relieve the anxiety linked to chronic (ongoing) Insomnia
  • Several medicines also can help relieve your Insomnia and allow you to re-establish a regular sleep schedule

If your Insomnia is the symptom or side effect of another problem, it's important to treat that problem (if possible).

Mirtazapine Insomnia Reviews

Tue, 21 Sep 2010

The above comment is too stupid, I actually LOLed at you Pete... lol you gave it 2 days and your complaining about the side-effects? and on 15 mgs? LMAO!!! It takes couple weeks at least to cope with the side-effects; just like many other drug. What is this; your first ever prescription medication? Your comment is misleading for others and very stupid.

I was on 45 mgs Mirtazipine for 2 years and even when I stopped abruptly I experienced zero to none of the withdrawal symptoms people are talking about... (but that might just be me, everyone is diff, however I never heard anyone dying from taking this medication. Unless combined with Benzos, pain killers and alcohol at the same time as it will def in that case cause severe CNS Depression and consequently death.

I would take 30 mg at nighttime for anxiety/Insomnia and 15mgs in the mornings or after lunch. It is an excellent antidepressant, however you munch out a lot while on it, and you def put of more weight than before you start the medication. So, if weight gain is an issue for you, stay away from this one. Talk to your physician about alternate choices. Probably the best is Welbutrin if you weight is an issue for you.

Wery tired and sleepy during the day, but suffering from Insomnia at night.

Tue, 07 Jun 2011
Mirtazapine has changed my life. I have experienced no negative side-effects from this drug. It has allowed me to live my life again, sleep, eat, and stress less. Perhaps this drug isn't for everyone... no medication is. BUT.. for some it is a godsend. I suffer from CPTSD, anxiety, loss of appetitie and Insomnia. Along with therapy and determination, this medication has been a useful tool for me to address my anxiety, and stress levels to build a better life. Hopefully, with time this will lead to new habits and new patterns without the anxiety, making this medication no longer necessary. Until then, I definately wont stop taking this Mirtazapine. at pete - the side effects of Mirtazapine are greater at lower doses (It's odd like that), anyway - after an initial settling in period once you have increased to the correct dose, those symptoms usually disappear. 8-)
