DOPEZIL-10

# DONEPEZIL 10 MG ## SHORT DESCRIPTION **Donepezil 10 mg** is a prescription medicine used to help manage symptoms of **Alzheimer's disease**. It belongs to a group of medicines called **acetylcholinesterase inhibitors**. Donepezil increases the availability of acetylcholine in the brain, which may help support memory, thinking, concentration, and the ability to perform daily activities. Donepezil **does not cure Alzheimer's disease or stop its underlying progression**, but it may temporarily improve or stabilize symptoms in some patients. --- # KEY BENEFITS * Helps improve or maintain **memory and thinking abilities** in some people with Alzheimer's disease. * May support concentration and cognitive function. * Can help with certain difficulties performing everyday activities. * May slow the rate of symptomatic decline in some patients. * Can be used in **mild, moderate, and severe Alzheimer's disease**, depending on clinical assessment. * Once-daily dosing can make treatment convenient. --- # USES / INDICATIONS Donepezil may be prescribed for: * **Alzheimer's disease** * Mild Alzheimer's dementia * Moderate Alzheimer's dementia * Severe Alzheimer's dementia It is primarily intended to manage cognitive and functional symptoms associated with Alzheimer's disease. > Donepezil does not cure dementia and is not effective for every cause of memory loss. --- # HOW IT WORKS Donepezil is a **reversible acetylcholinesterase inhibitor**. Acetylcholine is a chemical messenger involved in: * Memory * Learning * Attention * Thinking In Alzheimer's disease, cholinergic nerve activity can become reduced. Donepezil inhibits the enzyme **acetylcholinesterase**, which normally breaks down acetylcholine. This increases acetylcholine availability in the brain and may improve communication between nerve cells. ### In simple terms: **Donepezil → reduces breakdown of acetylcholine → increases acetylcholine activity → may support memory and cognitive function.** The medicine does not reverse the underlying brain changes caused by Alzheimer's disease. --- # DOSAGE & ADMINISTRATION The dose should be individualized by a healthcare professional. ### Typical Adult Dosing Treatment is commonly started at: **5 mg once daily** After an appropriate period of treatment and assessment of tolerability, the dose may be increased to: **10 mg once daily** The **10 mg dose should only be taken when prescribed**. ### How to Take * Take once daily, usually at approximately the same time each day. * It can generally be taken with or without food. * Swallow the tablet with water. * Do not take more than the prescribed dose. ### If You Miss a Dose Take the missed dose when remembered unless it is close to the next scheduled dose. **Do not take two doses together.** If donepezil has been stopped for several days, contact your healthcare professional before restarting because the dose may need to be reintroduced gradually. --- # SIDE EFFECTS ## Common Side Effects Possible side effects include: * Nausea * Diarrhea * Vomiting * Loss of appetite * Weight loss * Headache * Dizziness * Fatigue * Muscle cramps * Insomnia * Abnormal dreams These effects may be more noticeable when treatment is started or the dose is increased. ## Cardiovascular Effects Donepezil can sometimes slow the heart rate and may cause: * Slow heartbeat * Dizziness * Fainting Seek medical evaluation if unexplained fainting occurs. ## Serious Side Effects Seek urgent medical attention for: * Fainting or severe dizziness * Very slow or irregular heartbeat * Seizures * Severe abdominal pain * Black or bloody stools * Vomiting blood * Severe allergic reaction * Severe or persistent vomiting Rarely, gastrointestinal bleeding or heart rhythm abnormalities may occur. --- # PRECAUTIONS & WARNINGS ## Heart Problems Donepezil can slow the heart rate. Tell your doctor if you have: * Slow heartbeat * Heart conduction problems * Sick sinus syndrome * Unexplained fainting * Certain heart rhythm disorders ## Stomach Ulcers and GI Bleeding Donepezil may increase gastric acid secretion and may increase the risk of gastrointestinal problems. Tell your healthcare professional if you have a history of: * Stomach ulcers * Gastrointestinal bleeding * Severe gastritis Extra caution may be required if you take NSAIDs such as ibuprofen, naproxen, or aspirin. ## Asthma and Lung Disease Cholinesterase inhibitors can potentially increase bronchial activity. Tell your doctor if you have: * Asthma * Chronic obstructive pulmonary disease (COPD) * Other significant respiratory disease ## Seizures Donepezil may potentially lower the seizure threshold. Tell your doctor if you have a history of seizures or epilepsy. ## Urinary Problems Donepezil may increase bladder activity and should be used cautiously in people with urinary obstruction. ## Surgery and Anesthesia Tell your surgeon or anesthetist that you take donepezil before undergoing surgery. Donepezil can interact with certain **neuromuscular blocking medicines** used during anesthesia. ## Liver Disease Tell your healthcare professional if you have significant liver disease. ## Kidney Disease Dose adjustment is not generally required solely because of mild-to-moderate kidney impairment, but medical supervision remains important. ## Pregnancy and Breastfeeding Donepezil is generally used in older adults with Alzheimer's disease, and there is limited information regarding pregnancy. Tell your healthcare professional if you are pregnant, planning pregnancy, or breastfeeding. --- # DRUG INTERACTIONS ### Other Cholinergic Medicines Combining donepezil with other medicines that increase cholinergic activity may increase adverse effects. ### Anticholinergic Medicines Medicines with strong anticholinergic effects may reduce the effectiveness of donepezil. Examples include certain medicines used for: * Bladder problems * Motion sickness * Allergies * Certain psychiatric conditions ### NSAIDs Medicines such as: * Ibuprofen * Naproxen * Aspirin may increase gastrointestinal irritation or bleeding risk when used with donepezil. ### Beta-Blockers Medicines such as propranolol, atenolol, or metoprolol can also slow the heart rate. Combined use may increase the risk of **bradycardia or fainting** in susceptible individuals. ### Other Medicines Affecting Heart Rhythm Some medicines that prolong the QT interval may increase the risk of cardiac rhythm problems when combined with donepezil. ### CYP Enzyme Inhibitors/Inducers Some medicines can alter donepezil levels by affecting liver enzymes involved in its metabolism. Tell your doctor if you take: * Ketoconazole * Erythromycin * Rifampicin * Phenytoin * Carbamazepine * Other medicines that affect CYP enzymes Always provide your healthcare professional with a complete list of prescription medicines, OTC products, supplements, and herbal medicines. --- # STORAGE INFORMATION * Store according to the manufacturer's instructions. * Keep at the recommended room temperature. * Protect from excessive heat, moisture, and direct sunlight. * Keep the tablets in their original packaging. * Keep out of reach of children. * Do not use after the expiry date. * Do not use tablets that are damaged or significantly changed in appearance. --- # PRESCRIPTION STATUS **Donepezil 10 mg is generally a prescription medicine.** It should be started and monitored by a qualified healthcare professional experienced in treating dementia or cognitive disorders. --- # GENUINE MEDICINE ASSURANCE When purchasing **Donepezil 10 mg**, obtain it from a **licensed pharmacy or authorized medicine supplier**.
