Precautions
Drug information provided by: Merative, Micromedex®
It is very important that your doctor check the progress of you or your child at regular visits to allow for changes in the dose and to check for any unwanted effects.
For some children, teenagers, and young adults, this medicine can increase thoughts of suicide. Tell your doctor or your child's doctor right away if you or your child start to feel more depressed and have thoughts about hurting yourself. Report any unusual thoughts or behaviors that trouble you or your child, especially if they are new or are getting worse quickly. Make sure the doctor knows if you or your child have trouble sleeping, get upset easily, have a big increase in energy, or start to act reckless. Also tell the doctor if you or your child have sudden or strong feelings, such as feeling nervous, angry, restless, violent, or scared. Let the doctor know if you or anyone in your family has bipolar disorder (manic-depressive illness) or has tried to commit suicide.
Do not take doxepin if you have taken a monoamine oxidase (MAO) inhibitor (eg, isocarboxazid [Marplan®], phenelzine [Nardil®], selegiline [Eldepryl®], or tranylcypromine [Parnate®]) in the past 2 weeks. If you do, you may have confusion, agitation, restlessness, stomach or intestinal symptoms, a sudden high body temperature, an extremely high blood pressure, or severe convulsions.
If you or your child are using this medicine for depression or anxiety, do not stop taking it without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help prevent a possible worsening of your condition and reduce the possibility of withdrawal symptoms, such as headache, nausea, or a general feeling of discomfort or illness.
Silenor® tablets may cause sleep-related behaviors such as driving a car (sleep-driving), walking (sleep-walking), having sex, making phone calls, or preparing and eating food while asleep or not fully awake. If any of these reactions occur, tell your doctor right away.
If you think you need to take Silenor® tablets for 7 to 10 days, talk to your doctor.
This medicine may cause some people to become drowsy. Make sure you know how you react to this medicine before you drive, use medicines, or do anything else that could be dangerous if you are drowsy or not alert.
This medicine will add to the effects of alcohol and other CNS depressants (medicines that slow down the nervous system, possibly causing drowsiness). Some examples of CNS depressants are antihistamines or medicine for hay fever, allergies, or colds, sedatives, tranquilizers, or sleeping medicine, prescription pain medicine or narcotics, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics. This effect may last for a few days after you stop taking this medicine. Check with your doctor before taking any of the above while you or your child are using this medicine.
Tell your doctor if you are pregnant or planning to become pregnant during treatment with this medicine. This medicine may cause symptoms of sedation (eg, breathing problems, sluggishness, low muscle tone, feeding problems, or withdrawal symptoms) in the baby during the third trimester.
Talk with your doctor before using this medicine if you plan to have children. Some men and women who use this medicine have become infertile (unable to have children).
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines) and herbal or vitamin supplements.
