Before taking loxapine,
tell your doctor and pharmacist if you are allergic to loxapine or any other medications.
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: antidepressants; antihistamines; atropine (in Motofen, in Lomotil, in Lonox); barbiturates such as pentobarbital (Nembutal), phenobarbital (Luminal), and secobarbital (Seconal); epinephrine (Epipen); ipratropium (Atrovent); lorazepam (Ativan); medications for anxiety, irritable bowel disease, mental illness, motion sickness, Parkinson's disease, seizures, ulcers, or urinary problems; narcotic medications for pain; sedatives; sleeping pills; and tranquilizers. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
tell your doctor if you have or have ever had seizures, difficulty urinating, glaucoma (condition in which increased pressure in the eye can lead to gradual loss of vision), trouble keeping your balance, breast cancer, or heart disease. Also tell your doctor if you have ever had to stop taking any medication for mental illness due to severe side effects.
tell your doctor if you are pregnant, especially if you are in the last few months of your pregnancy, or if you plan to become pregnant or are breast-feeding. If you become pregnant while taking loxapine, call your doctor. Loxapine may cause problems in newborns following delivery if it is taken during the last months of pregnancy.
if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking loxapine.
you should know that this medication may make you drowsy and may affect your thinking and movements. Do not drive a car or operate machinery until you know how this medication affects you.
ask your doctor about the safe use of alcohol during your treatment with loxapine. Alcohol can make the side effects of loxapine worse.
you should know that loxapine may cause dizziness, fainting, and lightheadedness, especially when you get up from a lying position. To avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up.
