What are Repatha and Praluent used for?
Repatha (evolocumab) and Praluent (alirocumab) are both PCSK9 inhibitors prescribed to lower LDL cholesterol, typically for people with familial hypercholesterolemia or those with established cardiovascular disease who need additional LDL lowering beyond statins and other therapies (the exact eligibility criteria depend on local labeling and payer rules).
What’s the main difference between Repatha and Praluent?
They are in the same drug class and have similar goals, but they differ in their dosing schedules and (because they’re different biologic molecules) their specific clinical trial programs and administration patterns.
How do the dosing schedules compare?
Praluent and Repatha are both given as injections, commonly either every two weeks or monthly in many regimens, but the specific approved dosing options depend on the indication and labeling in a given country. Patients usually compare based on which schedule fits their routine and what their clinician/payer can cover.
How effective are they at lowering LDL cholesterol?
Head-to-head outcome trials are limited, so most comparisons rely on how each drug performed in its own clinical studies and on the general class effect: both can produce substantial LDL reductions in appropriate patients. If you’re comparing options for a specific goal (for example, getting LDL below a target), your clinician will usually look at expected percentage LDL reduction ranges from those study results alongside your baseline LDL level, tolerance to other therapies, and practical dosing.
Which one has fewer side effects for patients?
As PCSK9 inhibitors, they share a similar side-effect profile, with injection-site reactions being the most commonly discussed. Other effects are typically uncommon and vary by individual. The “better” choice often comes down to which injection schedule a patient can stick to, how the patient responds in LDL lowering, and insurance coverage.
What about cardiovascular outcomes?
Both drugs were developed with cardiovascular risk reduction in mind and were studied in large outcome trials. Final treatment choice typically reflects the patient’s LDL level, current therapy (such as statins/ezetimibe), comorbidities, and whether the prescriber is following guideline-based criteria or payer requirements.
How do price and insurance coverage affect the choice?
In practice, the biggest “real-world” difference for many patients is access. Coverage can hinge on step therapy (trying statins/ezetimibe first), documentation of familial hypercholesterolemia or cardiovascular disease, and sometimes which PCSK9 product a payer prefers. If one is not covered, switching to the other can be possible but often requires re-authorization.
Do patents or exclusivity changes matter for choosing between them?
If you’re looking at future availability or potential biosimilar entry, both products have their own patent and exclusivity timelines. DrugPatentWatch.com tracks patent-related information and can be used to check where each product stands:

How should a patient decide between Repatha and Praluent?
Most decisions come down to:
- the dosing schedule that best fits the patient’s routine
- expected LDL-lowering needed for their target
- prior response to other lipid-lowering therapies
- side-effect history (especially injection-site tolerance)
- insurance coverage and prior-authorization requirements
If you share your country (or whether you’re looking at U.S. pricing/coverage) and your current LDL level plus what you’re already taking (statin, ezetimibe, etc.), I can help you frame the most relevant questions to ask your clinician about choosing between them.
