Pharmacist tips for Donepezil (Aricept)

pharmacist
  • Take donepezil (Aricept) in the evening around bedtime. Taking it right before bedtime can help you sleep through some side effects like dizziness.
  • You can take donepezil (Aricept) with or without food. If you have nausea from the medication, taking it with food might help ease this side effect.
  • For the orally disintegrating tablet (ODT): Don't swallow the tablet whole. Place it on your tongue, and let the tablet dissolve. Drink a glass of water after the tablet dissolves to make sure you take your full dose.
  • Donepezil (Aricept) often causes diarrhea. If this happens, make sure to stay hydrated. Staying away from spicy, greasy, and high-fiber foods can also help with mild diarrhea. Watch for signs of dehydration and know when to get help. Ask a healthcare professional for more ways to manage diarrhea.
  • Try to avoid taking nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen (Advil). Taking them with donepezil (Aricept) can raise your risk of stomach ulcers and bleeding.
  • If you miss a dose of donepezil (Aricept), skip your missed dose. Wait to take your usual dose the next day. Don't take two doses at the same time to make up for a missed dose because this can raise your risk of side effects.

Common questions about Donepezil (Aricept)

It's recommended to take donepezil (Aricept) at night so you can sleep through some side effects like dizziness and stomach upset. But some people can have abnormal dreams or trouble sleeping when they take it at night. If this happens to you, talk to your prescriber about the best time for you to take donepezil (Aricept).

No, donepezil (Aricept) isn't an antipsychotic. It's a type of medication called a cholinesterase inhibitor. Donepezil (Aricept) helps stop the body from breaking down acetylcholine. This is a chemical in the brain that's important for memory and learning.

For mild-to-moderate Alzheimer's disease, the highest recommended dose of donepezil (Aricept) is 10 mg each day. For moderate-to-severe Alzheimer's disease, the highest recommended dose is 23 mg each day. Talk to your prescriber about what dose is right for you.

It depends on how much donepezil (Aricept) you've actually taken. But taking too high of a dose or too much can lead to more intense side effects like nausea and vomiting. It could also cause more side effects to happen. In severe cases, you could have seizures and breathing problems. If you think you might've taken too much donepezil (Aricept), call a Poison Control Center at 1-800-222-1222 right away.

No, donepezil (Aricept) isn't a controlled substance. It isn't known to cause misuse or dependence.

You might start to notice your memory or thinking get better within a month or so after you start taking donepezil (Aricept). Most studies looked at changes in memory, language, and attention after at least 1 month of treatment. Take the medication every day, even if you don't see a difference right away. Ask a caregiver to help you remember to take donepezil (Aricept), or set a reminder for yourself. Talk to your prescriber if you have questions about how long it's taking for the medication to work.

Sleepiness is a possible side effect of donepezil (Aricept). But it wasn't reported very often during studies. Tell your prescriber if you feel drowsy and it's bothering you or it doesn't go away.

Yes, you can take donepezil (Aricept) and memantine (Namenda) together. They work in different ways to help treat Alzheimer's disease. In fact, people who take memantine (Namenda) often take it together with donepezil (Aricept). There's even a single tablet that combines both medications (called Namzaric). Talk to your prescriber to see if taking both medications is right for you.

Risks and warnings for Donepezil (Aricept)

Donepezil (Aricept) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Slower heartbeat

Medications like donepezil (Aricept) can sometimes slow down your heartbeat. This can make you feel dizzy or out of breath. In some cases, slow heartbeat can lead to fainting. Let your prescriber know if you have any falls or start to feel lightheaded while taking donepezil (Aricept). They might need to lower your dose.

Nausea and vomiting

  • Risk factors: Taking a higher dose of donepezil (Aricept) | People weighing less than 121 lbs

Nausea, vomiting, and diarrhea are common side effects of donepezil (Aricept). These side effects are more common when you first start the medication and when you start a higher dose. They typically go away after a couple weeks of taking the same dose.

Tell your prescriber if you have nausea, vomiting, or diarrhea that bothers you a lot. This is important if the side effects keep you from taking your medication every day. Your prescriber can see how they can help you manage these side effects.

Stomach ulcers and bleeds

  • Risk factors: Taking nonsteroidal anti-inflammatory drugs (NSAIDs) | History of stomach ulcers or bleeds | Taking the 23 mg dose of donepezil (Aricept)

Donepezil (Aricept) can raise the amount of stomach acid your body makes. Although rare, this can put you at risk of stomach ulcers and bleeds.

People who take the 23 mg dose of donepezil (Aricept) might have a higher risk of these stomach issues. NSAIDs can also raise the risk of stomach bleeding. Because of this, you should try to avoid taking NSAIDs, which are common in over-the-counter cold and pain medications, at the same time as donepezil (Aricept).

Talk to a healthcare professional if you have stomach pain, heartburn, or indigestion that gets worse while taking donepezil (Aricept). These could be signs of a stomach ulcer. Also, watch out for possible signs of stomach bleeding like red, black, or tarry stool. The healthcare professional can help figure out what's going on.

Weight loss

  • Risk factors: Taking a higher dose of donepezil (Aricept)

In studies, some people lost weight while taking donepezil (Aricept). In general, more people who took the 23 mg dose lost weight than those who took the 10 mg dose of the medication. Tell your prescriber if this worries you or if you notice unexpected weight loss.

Caution use in people with urinary problems

Medications like donepezil (Aricept) can sometimes make it harder to fully empty your bladder. Tell your prescriber if you have any trouble urinating.

Caution use in people with breathing problems

  • Risk factors: Asthma | Chronic obstructive pulmonary disease (COPD)

Tell your prescriber if you have breathing problems, like asthma or COPD. Medications like donepezil (Aricept) might affect breathing. Your prescriber can talk to you about the risks and benefits of taking donepezil (Aricept).
