💡 KEY INSIGHT: Repatha (evolocumab) is an injectable PCSK9 inhibitor that can lower “bad” LDL cholesterol by roughly half — on top of a statin. It’s mainly for people at high cardiovascular risk or who can’t tolerate statins, and in Singapore it costs more than statins, so subsidy eligibility matters.
Updated 2026 · GaiaGuides · 9 min read
If statins alone haven’t brought your cholesterol down far enough — or if side effects mean you can’t take them — your doctor may have mentioned an injectable option called Repatha. It belongs to a newer class of cholesterol medicines, the PCSK9 inhibitors, that work very differently from statins and can dramatically lower LDL (“bad”) cholesterol.
This guide explains what Repatha (evolocumab) is, how PCSK9 inhibitors work, who actually needs them in Singapore, what they cost in 2026 and how subsidies fit in, the side effects to know, and how they compare with statins and the newer option inclisiran. Cholesterol treatment is a medical decision — this is background to discuss with your doctor, not a substitute for their advice.

Doctor-led review of your lipid profile and cardiovascular risk to see whether a PCSK9 inhibitor like Repatha is appropriate.
What Is Repatha (Evolocumab)?
Repatha is the brand name for evolocumab, a medicine given as an injection under the skin (usually once or twice a month). It treats high cholesterol in adults — and certain children with an inherited form — and is used to reduce the risk of heart attack and stroke in people with established cardiovascular disease. In Singapore, two PCSK9 inhibitors are registered for use: evolocumab (Repatha) and alirocumab.
Unlike statins, which you swallow daily, Repatha is a self-administered injection using a pre-filled pen. It’s almost always used in addition to a statin (and a healthy diet), not instead of one — unless statins aren’t tolerated.
How Do PCSK9 Inhibitors Work?
Your liver clears LDL cholesterol from the blood using LDL receptors. A protein called PCSK9 destroys those receptors, so the more PCSK9 you have, the fewer receptors survive and the higher your LDL stays. PCSK9 inhibitors like Repatha block that protein, so more receptors remain active, and the liver pulls more LDL out of the bloodstream.
The effect is powerful: PCSK9 inhibitors can lower LDL by around 50–60%, even on top of a statin. The U.S. National Heart, Lung, and Blood Institute and major cardiology guidelines recognise them as a key option for patients who remain high-risk despite maximal statin therapy.
Who Needs Repatha in Singapore?
PCSK9 inhibitors aren’t a first-line treatment — statins remain the foundation. Repatha is typically considered when:
- Statins aren’t enough. Your LDL stays above target despite the maximum tolerated statin dose (often combined with ezetimibe).
- You can’t tolerate statins. Genuine statin intolerance (e.g. significant muscle symptoms) leaves few oral options.
- You have familial hypercholesterolaemia (FH). This inherited condition causes very high LDL from a young age and often needs aggressive treatment.
- You’re at very high cardiovascular risk. For example, existing heart disease or a prior heart attack or stroke, where driving LDL much lower meaningfully reduces future events.
[Speak to a doctor first]
Whether Repatha is right for you depends on your LDL level, your overall cardiovascular risk, and what you’ve already tried. A lipid panel and a risk assessment — not a web article — should drive that decision.
Repatha vs. Statins vs. Inclisiran
| Feature | Statins | PCSK9 inhibitors (Repatha) |
| Form | Daily tablet | Injection, every 2–4 weeks |
| LDL reduction | ~30–50% | ~50–60% (added on top) |
| Cost | Low (often generic) | Higher; subsidy may apply |
| Best for | First-line for most | High-risk / statin-intolerant / FH |
A newer injectable, inclisiran, also targets PCSK9 but is dosed far less often (after the first two doses, roughly twice a year). Repatha has a longer track record and large outcome studies behind it; inclisiran offers convenience. Your doctor will weigh evidence, dosing, and cost for your situation.
Cost & Subsidies in Singapore (2026)
PCSK9 inhibitors remain considerably more expensive than statins. In Singapore, out-of-pocket costs typically run from several hundred to over S$1,000 per month, depending on the exact medicine and dosing schedule. Subsidies are available through national schemes for patients who meet specific clinical criteria, which can substantially reduce what you pay.
Because pricing and subsidy rules change, confirm the current figures and your eligibility with your treating doctor or clinic before starting. (US list-price news doesn’t reflect Singapore pricing, so be wary of overseas cost articles.)
How It’s Given & What to Expect
Repatha comes as a pre-filled pen or syringe that you inject into the abdomen, thigh, or upper arm — most people self-administer at home after a quick demonstration. Depending on the dose, that’s roughly once every two weeks or once a month. It’s stored refrigerated. Your doctor will recheck your lipids a few weeks after starting to confirm it’s working.
Side Effects & Safety
PCSK9 inhibitors are generally well tolerated. The most common side effects are mild injection-site reactions (redness, soreness), and cold-like or flu-like symptoms. Serious reactions are uncommon. As with any new medication, tell your doctor about all other medicines and any history of allergic reactions, and don’t stop or change your statin without medical advice.

Key Takeaway
Repatha (evolocumab) is a powerful, well-tolerated way to lower LDL cholesterol for people who need more than statins can deliver — those at high cardiovascular risk, with familial hypercholesterolaemia, or who can’t tolerate statins. The main trade-offs are cost and the need for injections, both of which are manageable with the right plan and subsidy support. The first step is a proper lipid and risk assessment with your doctor.

FAQs — REPATHA SINGAPORE
1. What is Repatha used for?
It lowers LDL (“bad”) cholesterol and reduces heart-attack and stroke risk in high-risk adults, usually alongside a statin. It’s also used in familial hypercholesterolaemia.
2. How much does Repatha cost in Singapore?
Out-of-pocket costs typically run from several hundred to over S$1,000 a month, depending on the medicine and dosing. Subsidies may apply if you meet clinical criteria — confirm current pricing with your clinic.
3. Is Repatha better than statins?
It’s not a replacement — statins remain first-line. Repatha is added when statins alone aren’t enough or aren’t tolerated, and it can lower LDL by a further 50–60%.
4. How often do you inject Repatha?
Depending on the dose, roughly once every two weeks or once a month, self-administered with a pre-filled pen.
5. What’s the difference between Repatha and inclisiran?
Both target the PCSK9 protein. Repatha is injected every 2–4 weeks and has extensive outcome data; inclisiran is dosed about twice a year after the initial doses. Your doctor will advise which suits you.
6. Does Repatha have serious side effects?
Most people tolerate it well; the commonest effects are mild injection-site reactions and cold-like symptoms. Discuss your full medical history with your doctor before starting.
A NOTE FROM GAIA GUIDES
Cholesterol care is deeply individual. Repatha is a genuinely effective tool for the right patient, but it sits on top of the basics — diet, exercise, and a statin where tolerated. Treat this guide as a conversation-starter for your next appointment, not a self-prescription.
