Amitrip (Amitriptyline) 25 mg
Why is Amitriptyline medication prescribed?
Amitriptyline is used to treat symptoms of depression. Amitriptyline is in a class of medications called tricyclic antidepressants. It works by increasing the amounts of certain natural substances in the brain that are needed to maintain mental balance.
How should Amitriptyline medicine be used?
Amitriptyline comes as a tablet to take by mouth. It is usually taken one to four times a day. Take amitriptyline at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take amitriptyline exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will probably start you on a low dose of amitriptyline and gradually increase your dose.
It may take a few weeks or longer before you feel the full benefit of amitriptyline. Continue to take amitriptyline even if you feel well. Do not stop taking amitriptyline without talking to your doctor. If you suddenly stop taking amitriptyline, you may experience withdrawal symptoms such as nausea, headache, and lack of energy. Your doctor will probably decrease your dose gradually.
Other uses for Amitriptyline medicine

Talk to your doctor about the possible risks of using this medication for your condition.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
