1. What Galantamine Viatris is and what it is used for

Galantamine Viatris contains galantamine, a medication for dementia, used to treat the symptoms of mild to moderate Alzheimer-type dementia, a disease that impairs brain function.

Symptoms of Alzheimer's disease include progressive memory loss, confusion, and behavioral disturbances. As a result, it becomes increasingly difficult to carry out daily activities.

These symptoms are thought to be due to a lack of acetylcholine, a substance responsible for communication between brain cells. Galantamine increases the amount of acetylcholine in the brain, which may help alleviate the symptoms of the disease.

The capsules are manufactured as "prolonged-release", meaning they allow the medication to be released slowly.

2. What you need to know before taking Galantamina Viatris

Do not take Galantamina Viatris:

• If you are allergic to galantamine or to any of the other ingredients of this medicine (listed in section 6).
• If you have severe liver and/or kidney disease.

Warnings and precautions

Talk to your doctor or pharmacist before starting Galantamina Viatris. This medicine should only be used for Alzheimer's disease and is not recommended for other types of memory loss or confusion.

Before starting treatment with this medicine, your doctor should know if you have or have had any of the following conditions:

• Other liver or kidney problems.
• Heart disorders (such as chest discomfort, usually caused by physical activity (angina), heart attack, heart failure, slow or irregular heartbeat, prolonged QTc interval).
• Reduced blood flow to the brain, stroke, or mini-stroke (also known as transient ischemic attack or 'TIA').
• Changes in electrolyte levels (if your blood potassium levels are low or high).
• Peptic ulcer (stomach).
• Blockage in the stomach or intestine (which may cause severe abdominal pain or acute constipation).
• Nervous system disorders [such as epilepsy or problems controlling body or limb movements (extrapyramidal disorder)].
• Respiratory disease or infection affecting breathing (such as asthma, obstructive lung disease, or pneumonia).
• Difficulty urinating.

Your doctor will decide whether galantamine is suitable for you or whether your dose needs to be adjusted.

Also tell your doctor if you have recently had surgery on your stomach, intestine, or bladder. Your doctor will determine whether this medicine is suitable for you.

If you need to undergo surgery requiring general anaesthesia, inform your doctor or healthcare professional that you are taking galantamine.

This medicine may cause weight loss. Your doctor will regularly monitor your weight while you are taking this medicine.

Other medicines and Galantamina Viatris

Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines, including those obtained without a prescription.

Galantamine should not be used with medicines that have a similar mode of action. These include:

• Donepezil or rivastigmine (for Alzheimer's disease).
• Ambenonium, neostigmine, or pyridostigmine (for severe muscle weakness).
• Pilocarpine (for dry mouth or dry eyes) when administered orally.

Some medicines may affect how galantamine works, or galantamine may reduce the effectiveness of other medicines taken at the same time. Your doctor may prescribe a lower dose of galantamine if you are taking any of the following medicines, for example:

• Paroxetine or fluoxetine (antidepressants).
• Quinidine (used for heart rhythm problems).
• Ketoconazole (antifungal).
• Erythromycin (antibiotic).
• Ritonavir (antiviral, HIV protease inhibitor).

Some medicines may be more likely to cause adverse effects in people taking galantamine. These include:

• Non-steroidal anti-inflammatory analgesics (e.g., ibuprofen), which may increase the risk of ulcers.
• Medicines for heart disorders or high blood pressure (such as digoxin, amiodarone, atropine, beta-blockers, or calcium channel blockers). If you are taking medicines for irregular heartbeat, your doctor may consider performing an electrocardiogram (ECG).
• Medicines that affect the QTc interval.

If you have any doubts, consult your doctor or pharmacist.
