PRECAUTIONS: Visit your prescriber or health care professional for regular checks on your progress. It can take several days before you feel the full effect of amitriptyline.
If you have been taking amitriptyline regularly for some time, do not suddenly stop taking it. You must gradually reduce the dose or you may get severe side effects. Ask your prescriber or health care professional for advice. Even after you stop taking amitriptyline it can still affect your body for several days.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how amitriptyline 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 prescriber 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.
Amitripyline may cause dry eyes and blurred vision. If you wear contact lenses you may feel some discomfort. Lubricating drops may help. See your ophthalmologist if the problem does not go away or is severe.
Amitriptyline may make your skin more sensitive to the sun. Keep out of the sun, or wear protective clothing outdoors and use a sunscreen. Do not use sun lamps or sun tanning beds or booths.
If you are diabetic, check your blood sugar more often than usual, especially during the first few weeks of treatment with amitriptyline. Amitriptyline can affect blood glucose (sugar) levels. Call your prescriber or health care professional for advice if you notice a change in the results of blood or urine glucose tests.
If you are going to have surgery or will need an x-ray procedure that uses contrast agents, tell your prescriber or health care professional that you are taking this medicine.
