What should I watch for while using this medicine?

Patients and their families should watch out for worsening depression or thoughts of suicide. Also watch out for sudden or severe changes in feelings such as feeling anxious, agitated, panicky, irritable, hostile, aggressive, impulsive, severely restless, overly excited and hyperactive, or not being able to sleep. If this happens, especially at the beginning of antidepressant treatment or after a change in dose, call your health care professional.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol may increase dizziness and drowsiness. Avoid alcoholic drinks.
Do not treat yourself for coughs, colds, or allergies without asking your doctor or health care professional for advice. Some ingredients can increase possible side effects.
Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water will help.
This medicine may cause dry eyes and blurred vision. If you wear contact lenses you may feel some discomfort. Lubricating drops may help. See your eye doctor if the problem does not go away or is severe.
This medicine can make you more sensitive to the sun. Keep out of the sun. If you cannot avoid being in the sun, wear protective clothing and use sunscreen. Do not use sun lamps or tanning beds/booths.
If you are diabetic, check your blood sugar more often than usual, especially during the first few weeks of treatment with this medicine. This medicine can affect blood sugar levels. Call your doctor or health care professional for advice if you notice a change in the results of blood or urine glucose tests.
Where should I keep this medicine?
Keep out of the reach of children.
Store at room temperature between 20 and 25 degrees C (68 and 77 degrees F). Throw away any unused medicine after the expiration date.
Amitriptyline is used for a number of medical conditions including: depressive disorders, anxiety disorders, attention deficit hyperactivity disorder, migraine prophylaxis, eating disorders, bipolar disorder, post-herpetic neuralgia, and insomnia.
It is also used as a preventive for patients with recurring biliary dyskinesia (sphincter of Oddi dysfunction).
Amitriptyline is also used in the treatment of nocturnal enuresis (bedwetting) in children.
Amitriptyline may be prescribed for other conditions such as cyclic vomiting syndrome, post-traumatic stress disorder (PTSD), chronic pain, tinnitus, chronic cough, carpal tunnel syndrome (CTS), fibromyalgia, vulvodynia, interstitial cystitis, male chronic pelvic pain syndrome, irritable bowel syndrome (IBS), diabetic peripheral neuropathy, neurological pain, laryngeal sensory neuropathy, chronic fatigue syndrome and painful paresthesias related to multiple sclerosis. Typically lower dosages are required for pain modification of 10 to 50 mg daily.
A randomized controlled trial published in June 2005 found that amitriptyline was effective in functional dyspepsia that did not respond to a first-line treatment (famotidine or mosapride).
The main two side effects that occur from taking amitriptyline are drowsiness and a dry mouth. Other common side effects of using amitriptyline are mostly due to its anticholinergic activity, including: weight gain, changes in appetite, muscle stiffness, nausea, constipation, nervousness, dizziness, tremor, blurred vision, urinary retention, and changes in sexual function. Some rare side effects include seizures, tinnitus, hypotension, mania, psychosis, sleep paralysis, hypnagogic or hypnopompic hallucinations related to sleep paralysis, heart block, arrhythmias, lip and mouth ulcers, extrapyramidal symptoms, depression, tingling pain or numbness in the feet or hands, yellowing of the eyes or skin, pain or difficulty passing urine, confusion, abnormal production of milk in females, breast enlargement in both males and females, fever with increased sweating, and suicidal thoughts. The Indianapolis Discovery Network for Dementia (IDND) rates amitriptyline as having definite anticholinergic effects. A side effect of many commonly used drugs with such effects appears to be to increase the risks of both cognitive impairment and death in older people, according to research led by the University of East Anglia (UEA). Amitriptyline can induce hepatotoxicity.
