Dosage for Zetia: What You Need to Know

If you have high cholesterol, your doctor might suggest Zetia as a treatment option. It’s a prescription drug used in adults and some children along with dietary changes to treat:

homozygous familial hypercholesterolemia
mixed hyperlipidemia
primary hyperlipidemia

Zetia may be used alone or in combination with other medications to lower different kinds of high cholesterol. It’s also used alone to lower the blood level of fats called plant sterols in people with homozygous sitosterolemia.

Zetia comes as a tablet you swallow. It contains the active ingredient ezetimibe. (An active ingredient is what makes a drug work.) It belongs to a group of drugs called cholesterol blockers.

This article describes the dosage of Zetia, as well as its strength and how to take it. To learn more about the drug, see this in-depth article.

Note: This article covers Zetia’s usual dosage, which is provided by the drugmaker. But when using Zetia, always take the dosage your doctor prescribes.

* With off-label use, a drug is prescribed in a way or for a condition it’s not been approved for.

Accessible drug containers and labels

Some pharmacies provide medication labels that:

have large print
use braille
feature a code you can scan with a smartphone to change the text to audio

Your doctor or pharmacist may be able to recommend pharmacies that offer these accessibility features if your current pharmacy doesn’t.

If you have trouble opening medication bottles, let your pharmacist know. They may have tips to help make it easier or may be able to supply Zetia in an easy-open container.

If you miss your regular daily dose of Zetia, take it as soon as you remember. If it’s close to your next dose, skip the missed dose and continue with your normal daily dosing schedule. Do not take two doses at once, as this could increase your risk of side effects.

If you need help remembering to take your dose of Zetia on time, try using a medication reminder. This can include setting an alarm or downloading a reminder app on your phone.

Do not take more Zetia than your doctor prescribes, as this can lead to serious side effects.
