Warnings & Precautions
Before taking amoxapine:
- tell your doctor and pharmacist if you are allergic to amoxapine, doxepin (Sinequan), any other medications, or any of the inactive ingredients in amoxapine tablets. Ask your doctor or pharmacist for a list of the inactive ingredients.
- tell your doctor if you are taking a monoamine oxidase (MAO) inhibitor such as isocarboxazid (Marplan), phenelzine (Nardil), selegiline (Eldepryl, Emsam, Zelapar), and tranylcypromine (Parnate), or if you have stopped taking an MAO inhibitor within the past 14 days. Your doctor will probably tell you not to take amoxapine. If you stop taking amoxapine, you should wait at least 14 days before you start to take an MAO inhibitor.
- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: anticoagulants (blood thinners) such as warfarin (Coumadin); antihistamines; cimetidine (Tagamet); flecainide (Tambocor); levodopa (Sinemet, Larodopa); lithium (Eskalith, Lithobid); medications for high blood pressure, seizures, Parkinson’s disease, asthma, colds, or allergies; methylphenidate (Ritalin); muscle relaxants; propafenone (Rhythmol); quinidine; sedatives; selective serotonin reuptake inhibitors (SSRIs) such as citalopram (Celexa), escitalopram (Lexapro), fluoxetine (Prozac, Sarafem), fluvoxamine (Luvox), paroxetine (Paxil), and sertraline (Zoloft); sleeping pills; thyroid medications; and tranquilizers. Your doctor may need to change the doses of your medications or monitor you more carefully for side effects.
- tell your doctor if you are being treated with electroshock therapy (a procedure in which small electric shocks are administered to the brain to treat certain mental illnesses) and if you have or have ever had a heart attack, glaucoma (an eye disease), an enlarged prostate (a male reproductive organ), difficulty urinating, seizures, an overactive thyroid gland, or liver, kidney, or heart disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while taking amoxapine, call your doctor immediately.
- talk to your doctor about the risks and benefits of taking amoxapine if you are 65 years of age or older. Older adults should not usually take amoxapine because it is not as safe or effective as other medications that can be used to treat the same condition.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking amoxapine.
- you should know that this medication may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
- remember that alcohol can add to the drowsiness caused by this medication.
Amoxapine comes as a tablet to take by mouth. It is usually taken one or more times a day. If you take amoxapine once a day, you should take it at bedtime. Try to take amoxapine 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 amoxapine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
It may take several weeks or longer for you to feel the full effect of amoxapine. Continue to take amoxapine even if you feel well. Do not stop taking amoxapine without talking to your doctor. Your doctor probably will want to decrease your dose gradually.
