Endep is a tricyclic antidepressant used to treat depression and chronic pain. Endep improves the symptoms of depression by correcting the balance of the chemicals in your brain such as norephinephrine and serotonin. These chemicals help improve the mood of the patient and cope with depression.
Use Endep as directed by your doctor.
- Endep may be taken with food or on an empty stomach.
- Do not take the medication in larger amounts, or take it for longer than recommended by your doctor.
- Avoid eating grapefruit or drinking grapefruit juice while taking Endep.
- Do not stop using Endep without first talking to your doctor. You may need to use less and less before you stop the medication completely. Stopping this medication suddenly could cause you to have unpleasant side effects.
- Endep may take up to 30 days to control symptoms of depression. Continue to use Endep even if you feel well. Do not miss any doses.
- Talk with your doctor if your symptoms do not improve after 4 weeks of treatment.
- If you need to have any type of surgery, tell the surgeon ahead of time that you are taking Endep. You may need to stop using the medicine for a short time.
- If you miss a dose of Endep, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
The dosage for Endep depends on the condition of the patient. Only the doctors can decide on how much the dosage should be given to a patient. Usually a low dose of Endep is given at a certain period and will gradually increase depending on the tolerance and improvement of the patient.
Initial dosage usually starts at 75 milligrams up to 159 milligrams a day which is divided in smaller doses. For confined patients in hospitals, doctors usually administer 100 to 200 milligrams a day.
Elderly patients are usually provided with low dosage since they are not capable of the tolerance because of their age. Doctors usually reduce the dosage as the patient improves. Constant monitoring of the patient’s condition is required so as to determine if the dosage should be increased or decreased.
Ask your health care provider any questions you may have about how to use Endep.

Important safety information:
- Endep may cause dizziness, drowsiness, or blurred vision. Do not drive, operate machinery, or do anything else that could be dangerous until you know how you react to Endep. Using Endep alone, with other medicines, or with alcohol may lessen your ability to drive or perform other potentially dangerous tasks.

- Endep may cause dizziness, lightheadedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.
- Involuntary and uncontrollable movements may develop in patients taking Endep. Occurrence is highest among the elderly, especially women. The risk of developing these involuntary movements and the likelihood they will become permanent are increased with long-term use and with high doses. However, it is possible to develop these symptoms after short-term use at low doses. Contact your health care provider at once if any of the following occur: involuntary movements of the tongue, face, mouth, or jaw (eg, protrusion of tongue, puffing of cheeks, puckering of mouth, chewing movements), sometimes accompanied by involuntary movements of the arms and legs.
- Endep may cause sensitivity to sunlight. Avoid prolonged exposure to the sun and other ultraviolet light (eg, tanning beds). Use sunscreens and wear protective clothing until tolerance is determined.
