Amitriptyline for Fibromyalgia. An Excellent Research

Amitriptyline for fibromyalgia

A small dose of amitriptyline seems to help fibromyalgia patients rather than a high dose

Fibromyalgia is a chronic condition that causes severe wide-spread musculoskeletal pain. The causes of fibromyalgia are still not known but the symptoms include depression, sleep disorders, painful tender points and much more.

There are different types of medication for treating fibromyalgia. Tricyclic anti-depressants which include Amitriptyline, Nortriptyline and Doxepin are commonly used in the treatment of fibromyalgia.

Out of these three Tricyclic anti-depressants, Amitriptyline is the most common as it was found to be more effective compared to the other two.

What is amitriptyline?

Amitriptyline is a tricyclic antidepressant that is used to treat symptoms of depression. It is also used widely to treat fibromyalgia and chronic neuropathic pain. Amitriptyline is commonly sold under the brand name “Elavil”.

Amitriptyline works by increasing the amount of natural substance in the brain that is necessary for the brain to maintain mental balance. It is considered to be one of the most common medications prescribed for fibromyalgia patients.

Does Amitriptyline work on fibromyalgia patients?

Many studies have shown that tricyclic anti-depressants are effective compared with placebo in the treatment of fibromyalgia. Amitriptyline’s efficacy has been demonstrated in controlled studies and it reported to improve stage three and stage four sleep.

According to a study, the use of Amitriptyline in people suffering from fibromyalgia has provided pain relief.

In the study 70 fibromyalgia patients were evaluated. Fibromyalgia patients who were given 50 mg of Amitriptyline reported significant improvement in the quality of sleep, morning stiffness, pain analog and global assessment. However, it was also reported that tender point score did not improve.

The study also revealed some common side effects of Amitriptyline which included morning sedation, dry mouth, confusion and urinary retention. It was found that fibromyalgia patients were more sensitive to these side effects.

The study concluded that the dose should be individualized and generally begun at the lowest possible dose (such as 5 to 10 mg) at nighttime.

Taking the drug 1 to 2 hours prior to sleep can minimize difficulties with morning sedation or “hangover”. If there is no response, the dose can increase after 2 to 3 weeks.

Amitriptyline Dosage

Many experts recommend that the dosage of amitriptyline should be individualized or initially start with a low dosage.

A study published in the Oxford Journals assessed the efficacy and safety of amitriptyline as a treatment of fibromyalgia. It evaluated several randomized controlled trials.

The study found that 25 mg a day of amitriptyline in six randomized controlled trials demonstrated a therapeutic response compared with placebo in the domains of pain, sleep, fatigue and overall patient and investigator impression. This benefit was generally seen at 6–8 weeks of treatment but no effect was noted at 12 weeks.

Whereas 50 mg of amitriptyline a day in four randomized controlled trials did not demonstrate any therapeutic effect compared with placebo.

It was also revealed that neither dose of amitriptyline (25 mg and 50 mg) had an effect on tender points count.

Although a definitive clinical recommendation regarding the efficacy of amitriptyline for FM symptoms couldn’t be made, the study concluded that there is some evidence supporting the efficacy of amitriptyline 25 mg for the short-term treatment of fibromyalgia symptoms whereas there is no evidence supporting the use of higher doses of amitriptyline or using it for periods longer than 8 weeks.
