Drowsiness, dizziness, difficulty urinating, dry mouth, constipation, headache, weakness, blurred vision, or changes in appetite/weight may occur as your body gets used to the medication. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
To relieve dry mouth, suck on (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water or use a saliva substitute. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
To prevent constipation, maintain a diet adequate in fiber, drink plenty of water, and exercise. If you become constipated while using this drug, consult your pharmacist for help in selecting a laxative (e.g., stimulant-type with stool softener).
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor immediately if any of these unlikely but serious side effects occur: dizziness/fainting, feelings of restlessness, mental/mood changes (e.g., confusion, depression, hallucinations, nervousness), numbness/tingling of the hands/feet, ringing in the ears, shakiness (tremors), stomach/abdominal pain, severe vomiting/constipation.
Get medical help right away if you have any very serious side effects, including: chest pain, jaw/left arm pain, slow/fast/irregular heartbeat, pain/redness/swelling of arms/legs, seizures, severe headache, weakness on one side of the body, eye pain/swelling/redness, vision changes (such as seeing rainbows around lights at night), slurred speech.
In rare instances, this medication may increase your level of a certain natural chemical made by the body (prolactin). For females, this increase in prolactin may result in unwanted breast milk, missing/stopped periods, or difficulty becoming pregnant. For males, it may result in decreased sexual ability, inability to produce sperm, or enlarged breasts. If you develop any of these symptoms, tell your doctor immediately.
This drug may rarely cause a condition known as tardive dyskinesia. In some cases, this condition may be permanent. Tell your doctor immediately if you develop any unusual/uncontrolled movements (especially of the face, mouth, tongue, arms or legs).
Amoxapine may rarely cause a serious condition called neuroleptic malignant syndrome. Seek immediate medical attention if you develop the following: fever, muscle stiffness, increased sweating, fast/irregular heartbeat, severe confusion.
This medication may rarely cause serious blood problems (e.g., agranulocytosis, thrombocytopenia) or liver problems. Seek immediate medical attention if you notice any of the following rare but very serious side effects: easy bleeding/bruising, signs of infection (e.g., fever, persistent sore throat), severe stomach/abdominal pain, dark urine, yellowing of the eyes/skin.
A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
