How does this medication work? What will it do for me?

Galantamine belongs to the family of medications called cholinesterase inhibitors. It is used to treat symptoms of mild-to-moderate Alzheimer's disease.

Alzheimer's disease is caused by the constant degeneration of certain nerve cells in the brain that make a chemical called acetylcholine. This chemical is thought to be important for the processes of learning and memory. Galantamine prevents the breakdown of acetylcholine, thereby increasing its levels in the brain. Galantamine is of the most benefit in mild-to-moderate disease and is of little benefit when the disease becomes severe.

Galantamine may improve cognitive function (memory, orientation, and language) and general ability to perform activities of daily living.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

How should I use this medication?

The usual recommended starting dose of galantamine is 8 mg once daily. After at least 4 weeks of treatment, the dose may be increased to 16 mg once daily. After at least 4 more weeks of treatment, the dose may be increased further to 24 mg once daily.

Galantamine capsules should be taken once daily in the morning with food. Swallow the capsules whole. Do not open, divide, crush, or chew them.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

People with Alzheimer's disease and their caregivers should be aware that if treatment has been interrupted for several days or longer, this medication should be restarted at the lowest dose and then increased to the most current dose. If several doses are missed, do not restart galantamine on your own. It will be necessary to start at a lower dose and gradually increase to your previous dose. Consult your doctor if you miss several doses in a row.

Store this medication at room temperature and keep it out of the reach of children.

Are there any other precautions or warnings for this medication?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Bladder problems: Galantamine can make it more difficult to empty the bladder and may contribute to urinary tract problems. If you have bladder problems or a history of urinary tract problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Drowsiness/reduced alertness: Galantamine may affect the mental or physical abilities needed to drive or operate machinery. Avoid driving, operating machinery, or performing other hazardous tasks until you have determined how this medication affects you.

Gender: Women are more likely to experience side effects such as nausea and vomiting. This is also more likely to happen for women who are underweight.

Heart disease: Galantamine can cause slowed heart rate, affecting people with congestive heart failure (CHF) or coronary artery disease (CAD). If you have a heart condition, including blood pressure problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Kidney function: If you have kidney disease or decreased kidney function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Galantamine is not recommended for people with severely reduced kidney function.

Liver function: If you have liver disease or reduced liver function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Galantamine is not recommended for people with severely reduced liver function.

Lung disease: Galantamine can worsen the symptoms of breathing problems, such as asthma or chronic obstructive pulmonary disease (COPD) emphysema, and bronchitis. If you have asthma, COPD, or any other breathing problem, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Movement disorders: Galantamine may cause movement problems such as slow movements, stiffness, tremor, and other symptoms similar to Parkinson's disease such as restlessness, tremor, muscle spasms, or uncontrolled movements of the face, arms or legs. Contact your doctor if you experience any of these effects.

Seizures: An increase in seizures has been reported by people taking galantamine. It is unclear whether this is because of the medication or the Alzheimer's disease. If you have or have had a seizure disorder, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Stomach ulcers: Galantamine can cause an increase in the amount of acid produced by the stomach, increasing the risk for stomach ulcers. If you have or have had stomach problems, or take nonsteroidal anti-inflammatory (NSAIDs) medications, you are at increased risk of stomach problems with this medication. If you have any of these conditions, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Surgery: Galantamine can cause changes in how some medications used in surgery affect the body. If you are scheduled for surgery, let your medical team know that you are taking this medication.
