Amitriptyline belongs to a family of medications known as tricyclic antidepressants. It is used to treat Depression. It works in the central nervous system (CNS) to elevate the mood of people with depression. It is believed to work by keeping the balance of natural chemicals (neurotransmitters) in the body, namely serotonin and norepinephrine. It may start to work within 3 to 4 days, but it may take up to 30 days to see the full effects.

Bio Amitriptyline may be available under multiple brand names and/or in several different forms. Any specific brand name of Bio Amitriptyline may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Bio Amitriptyline may not be used for all of the conditions discussed here.

Your doctor may have suggested Bio Amitriptyline for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking Bio Amitriptyline, speak to your doctor. Do not stop taking Bio Amitriptyline without consulting your doctor.

Do not give Bio Amitriptyline to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take Bio Amitriptyline if their doctor has not prescribed it.

The usual starting dose of amitriptyline for depression in adults is 25 mg 3 times a day. The dose of amitriptyline is usually started low and increased slowly as prescribed by the doctor until the medication is at a dose that is appropriate and effective. After symptoms improve, the dose may be reduced to the lowest amount that will relieve symptoms. The usual maintenance dose of amitriptyline for adults ranges from 50 mg to 100 mg per day in divided doses. For some people, the daily dose can be given as a single dose, preferably at bedtime.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take Bio Amitriptyline exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule.
