What is Zetia?
Zetia is a brand-name prescription medication used to manage various types of high cholesterol in adults and some children. It is typically prescribed alongside a low-cholesterol diet.
Specifically, Zetia is indicated for treating primary hyperlipidemia, mixed hyperlipidemia, homozygous familial hypercholesterolemia, and homozygous sitosterolemia. It can be used alone or in combination with other cholesterol-lowering drugs.
Zetia is an oral tablet that belongs to a class of drugs known as intestinal cholesterol blockers. Its active ingredient is ezetimibe, which is also available in a generic form.
Zetia Side Effects
Like most medications, Zetia can cause side effects, which may be mild or serious. The occurrence and severity of side effects can depend on factors such as age, existing health conditions, and other medications being taken.
Mild Side Effects
When taken alone, mild side effects of Zetia may include infections (such as respiratory or sinus infections), diarrhea, pain in the arms or legs, and joint pain.
When taken with a statin (another type of cholesterol-lowering drug), mild side effects may include infections (such as respiratory infection or cold), diarrhea, headache, muscle cramps or pain, and joint pain.
Many mild side effects typically resolve within a few days to a couple of weeks. If they persist or become bothersome, medical consultation is advised.
Serious Side Effects
Serious side effects from Zetia are less common but can occur. These include muscle damage, potentially leading to rhabdomyolysis (breakdown of muscle tissue), liver damage (especially when taken with a statin), and allergic reactions. Immediate medical attention is necessary if serious side effects are experienced.
Side Effect Details
Liver Damage: Taking Zetia with a statin medication can lead to increased liver enzyme levels, which may indicate liver damage. Symptoms can include yellowing of the eyes or skin, nausea or vomiting, dark urine, and abdominal pain. Liver function is typically monitored before and during treatment when Zetia is combined with a statin.
Joint Pain: Joint pain is a commonly reported side effect, whether Zetia is taken alone or with a statin. If joint pain is severe or bothersome, treatment options or alternative medications may be discussed with a doctor.
Muscle Problems: Muscle problems, ranging from mild pain or cramping to severe conditions like rhabdomyolysis, can occur with Zetia, particularly when combined with a statin. The risk of serious muscle problems may be higher with high-dose statins, in individuals aged 65 or older, those with hypothyroidism or kidney problems, or when taking other muscle-problem-inducing medications. Muscle health is monitored during treatment, and any muscle symptoms should be reported to a doctor.
Frequently Asked Questions About Zetia
How Does Zetia Work and How Long Does It Stay in the System?
Zetia works by blocking the intestines from absorbing cholesterol. This mechanism helps the body eliminate excess cholesterol from the blood, thereby lowering cholesterol levels. Most of a Zetia dose is cleared from the body within 22 hours, with complete elimination potentially taking up to 5 days.
Are There Foods to Avoid While Taking Zetia?
A low-cholesterol diet is generally recommended during Zetia treatment to help maintain low cholesterol levels. Food does not appear to affect Zetia’s absorption or efficacy. However, if Zetia is taken with a statin, grapefruit and grapefruit juice should be avoided, as grapefruit can interfere with the statin’s breakdown, potentially increasing drug levels and side effect risk.
Does Zetia Cause Memory Loss, Weight Gain, Hair Loss, or Constipation?
Zetia is not known to cause memory loss, weight gain, hair loss, or constipation. These side effects were not reported in studies. If such symptoms occur, a doctor should be consulted to determine the underlying cause.
How Does Zetia Compare with Statins?
Both Zetia and statins are prescribed to lower cholesterol, and they can be taken together. They work through different mechanisms. Statins, such as atorvastatin (Lipitor), simvastatin (Zocor), pravastatin, lovastatin (Altoprev), and rosuvastatin (Crestor), are typically taken once daily, similar to Zetia.
Are There Side Effects from Stopping Zetia?
Discontinuing Zetia will likely lead to an increase in cholesterol levels, as the medication actively works to lower them. While immediate physical changes may not be noticeable, stopping cholesterol medication can elevate the risk of serious cardiovascular events like heart attack and stroke. Any concerns about stopping treatment should be discussed with a doctor.
Does Zetia Cause High Blood Pressure, Raised Blood Sugar, or Erectile Dysfunction?
Zetia is not known to cause high blood pressure, high blood sugar, or erectile dysfunction. These were not reported as side effects in studies. Individuals with these conditions should discuss appropriate treatment options with their doctor.
Is Zetia a Blood Thinner?
No, Zetia is not a blood thinner. While it helps reduce high cholesterol in the blood, it does not affect blood clotting. If taking Zetia with a blood thinner like warfarin, blood clotting ability may be monitored more frequently, and warfarin dosage might be adjusted.
Zetia Dosage
The prescribed dosage of Zetia is determined by a doctor. Zetia is available as a 10 mg oral tablet, typically taken once daily, with or without food.
Missed Dose
If a dose is missed, it should be taken as soon as remembered. However, no more than one dose of Zetia should be taken per day.
Long-Term Use
If Zetia proves effective, long-term use is generally recommended. It may take approximately 2 weeks for Zetia to begin lowering cholesterol. Regular blood tests will monitor its effectiveness, even if no immediate physical changes are felt.
What is Zetia Used For?
Zetia is prescribed to treat specific types of high cholesterol in adults and children aged 10 years and older, in conjunction with a low-cholesterol diet. High cholesterol increases the risk of heart disease, potentially leading to serious issues like heart attack or stroke.
For children, Zetia is not prescribed with other cholesterol drugs. For adults, it may be prescribed alongside other cholesterol-lowering medications.
Specific Conditions Treated by Zetia:
-
Primary Hyperlipidemia: A genetic condition causing high cholesterol. Zetia may be prescribed alone or with a statin to lower total cholesterol, LDL cholesterol (bad cholesterol), apolipoprotein-B (Apo-B), and non-HDL cholesterol.
-
Mixed Hyperlipidemia: A genetic condition characterized by high cholesterol and high triglycerides. Zetia is taken with fenofibrate (Antara) for this condition, working to lower total cholesterol, LDL cholesterol, Apo-B, non-HDL cholesterol, and triglycerides.
-
Homozygous Familial Hypercholesterolemia (HoFH): A genetic condition resulting in very high LDL cholesterol levels. Zetia is prescribed with either simvastatin or atorvastatin to lower total cholesterol and LDL cholesterol.
-
Homozygous Sitosterolemia: A condition where the body cannot break down plant sterols, leading to their buildup and increased risk of heart disease. Zetia lowers levels of sitosterol and campesterol.
Zetia’s action of blocking intestinal cholesterol absorption helps the body remove excess cholesterol, thereby reducing cholesterol levels and the risk of heart disease.
It is not currently known if Zetia affects the likelihood of cardiovascular disease or related illnesses, nor if it is effective for rare forms of high cholesterol such as Fredrickson Type I, III, IV, and V dyslipidemias.
What Does Zetia Cost?
The cost of prescription drugs can vary based on insurance coverage and pharmacy. Zetia is available as a generic drug, ezetimibe, which typically costs less than the brand-name version. Patients with questions about prescription costs or payment assistance options can consult their doctor or pharmacist.
How is Zetia Taken?
Zetia is an oral tablet taken once daily, with or without food. If also taking a bile acid sequestrant (e.g., cholestyramine, colesevelam), Zetia should be taken either 2 hours before or 4 hours after the sequestrant.
Accessible Medication
Pharmacies may offer medication labels with large print, Braille, or scannable codes for audio conversion. Easy-open containers or tools to assist with opening bottles may also be available for those with difficulty.
Taking Zetia with Other Drugs
In some cases, Zetia may be prescribed with other cholesterol-lowering medications in addition to a low-cholesterol diet. For primary hyperlipidemia, it may be taken alone or with a statin. For homozygous familial hypercholesterolemia, it may be prescribed with atorvastatin or simvastatin. For mixed hyperlipidemia, it is taken with fenofibrate.
Chewing, Crushing, or Splitting Tablets
It is recommended to swallow Zetia tablets whole, as it is not known if chewing, crushing, or splitting them is safe. If swallowing difficulties arise, a doctor or pharmacist should be consulted.
What to Consider Before Taking Zetia
Before starting Zetia, a comprehensive discussion with a doctor about health history, existing medical conditions, and all current medications (including over-the-counter drugs, vitamins, herbs, and supplements) is crucial to determine if Zetia is a safe and appropriate treatment option.
Interactions
Zetia can interact with several types of drugs, including fibrate drugs (e.g., fenofibrate), bile acid sequestrants (e.g., cholestyramine, colesevelam), and cyclosporine. If taking any of these, a doctor will likely recommend spacing out the doses from Zetia.
Warnings
-
Liver Problems: Individuals with liver problems should discuss this with their doctor before taking Zetia, especially if combined with a statin, as this can worsen existing liver conditions or cause new ones. Blood tests may be performed to assess safety.
-
Allergic Reaction: Zetia is not prescribed to individuals with a history of allergic reaction to the drug or its ingredients.
-
Kidney Problems: If kidney problems are present and Zetia is taken with a statin, there is an increased risk of muscle problems. Monitoring for muscle issues may be more frequent, and alternative treatments might be considered if symptoms develop.
-
Hypothyroidism (Underactive Thyroid Gland): Individuals with hypothyroidism taking Zetia with a statin may also have an increased risk of muscle problems, which can be serious. Close monitoring for muscle symptoms is advised, and a different treatment option may be recommended if symptoms occur.
Zetia and Alcohol
Zetia is not known to interact with alcohol. However, alcohol can cause liver problems. If Zetia is taken with a statin, the risk of liver problems is already increased, and alcohol consumption may further elevate this risk. Discuss safe alcohol consumption levels with a doctor.
Pregnancy and Breastfeeding
The safety of Zetia during pregnancy or breastfeeding is not established. Statins, often prescribed with Zetia, should not be taken during pregnancy or breastfeeding. Individuals who are pregnant, breastfeeding, or planning either should consult their doctor before starting Zetia to determine its safety.
What to Do in Case of Overdose
Taking more Zetia than prescribed can lead to serious side effects. In one reported instance of a significantly higher dose, no side effects were noted, but it is crucial to adhere strictly to the prescribed dosage. If an overdose is suspected, medical advice should be sought immediately.
Questions to Ask Your Doctor
Before starting Zetia, consider asking your doctor about managing potential side effects, how other medical conditions might affect side effect risk, what to do if pregnancy occurs during treatment, whether the dose can be lowered if side effects are experienced, and what medical tests will be needed during treatment.
