It is very important that your doctor check you at regular visits.
Tell your doctor if your symptoms get worse, or if you notice any new symptoms.
Do not take other medicines unless they have been discussed with your doctor. This especially includes nonprescription medicines, such as aspirin, and medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems.
Galantamine causes a large number of patients to have problems with their stomachs and intestines. Tell your doctor about any nausea, vomiting, diarrhea, stomach pain or loss of appetite.
If you think you or someone else may have taken an overdose of galantamine, get emergency help at once. Taking an overdose of galantamine may lead to convulsions (seizures) or shock. Some signs of shock are large pupils, irregular breathing, and fast weak pulse. Other signs of an overdose are severe nausea and vomiting, increasing muscle weakness, greatly increased sweating, and greatly increased watering of the mouth.
