Zetia is a brand-name medication that contains ezetimibe as its sole active ingredient. It belongs to the cholesterol-lowering class of drugs and is approved in Hong Kong for the treatment of high cholesterol (hypercholesterolemia). Zetia is supplied as a 10 mg pill that can be taken with or without food. The product is available only by prescription and is regulated by the Hong Kong Department of Health.
Ezetimibe reduces the amount of cholesterol that enters the bloodstream from the diet and bile. It does this by selectively inhibiting the NPC1L1 (Niemann-Pick C1-like 1) transporter located on the brush-border of intestinal cells. When NPC1L1 is blocked, the absorption of dietary and biliary cholesterol declines by about 50 %. The lowered influx of cholesterol leads to a reduction in circulating low-density lipoprotein cholesterol (LDL-C), the primary “bad” cholesterol linked to cardiovascular disease. Onset of action typically occurs within a few days, with peak effect seen after 2 weeks of consistent dosing.
The medication is indicated for patients who require a further decrease in LDL-C after maximally tolerated statin therapy or for those who cannot tolerate high-intensity statins.
Note: Patients should always provide a complete medication list, including over-the-counter products and herbal supplements, to their healthcare provider before starting Zetax.

Yes. Ezetimibe’s absorption is not significantly affected by food, so the pill can be taken with or without meals.
Zetia is often prescribed as add-on therapy when a statin alone does not achieve LDL-C targets. The combination should be monitored for liver enzymes and muscle symptoms.
A meaningful decrease in LDL-C is usually observed within 2 weeks, with maximal effect reached after about 4-6 weeks of consistent use.
Report the symptom to your healthcare provider. Persistent gastrointestinal discomfort may warrant evaluation for alternative therapy or dose adjustment.
St John’s Wort is a strong CYP3A4 inducer and may lower ezetimibe levels, potentially reducing its effectiveness. Discuss all supplements with your prescriber.
Yes, but keep the medication in its original packaging with a copy of the prescription. Some countries may require a letter from your doctor for controlled medications, although Zetia is not controlled.
Zetia is contraindicated in active, clinically significant liver disease. Patients with mild, stable liver conditions should be evaluated individually.
Statins inhibit cholesterol synthesis in the liver, whereas Zetia blocks dietary and biliary cholesterol absorption in the intestine. Their mechanisms are complementary, which is why they are often combined.
Coverage varies by provider and plan. It is advisable to check directly with your health insurance scheme or the Hospital Authority for formulary status.
