Leqvio Hair and Skin Changes: What the Evidence Can Show

Hair shedding after a Leqvio (inclisiran) injection deserves attention, even when the cause is uncertain. The available studies describe injection-site reactions more clearly than hair changes. They do not provide a dependable rate of hair loss caused by inclisiran or establish whether its risk matches the background rate.

What the studies establish

In the prescribing information’s pooled adult trials, injection-site reactions occurred in about 8% of inclisiran recipients and 2% of placebo recipients. This category includes pain, redness and rash where the injection was given. Those figures describe local reactions, not every possible skin problem.[1]

ORION-10 and ORION-11 followed 3,178 randomized participants for 540 days. Injection-site adverse events were generally mild, with none described as severe or persistent. These findings cannot promise a particular recovery time for every patient.[2]

Longer follow-up adds useful safety information. ORION-3 followed participants for four years, while ORION-8 reported a mean cumulative exposure of 3.7 years, including parent studies. Both were open-label extensions. They did not establish a quantified alopecia risk or exclude very rare reactions.[3][4]

Read the pattern before assigning a cause

Diffuse shedding, a discrete bald patch and redness at an injection site need different assessments. The table below connects an observable pattern with the limits of the evidence; it cannot identify the cause on its own.

Symptom patternUseful next stepWhat the evidence cannot settle
Redness, soreness or swelling confined to the injection areaPhotograph the area and note whether it is improving, spreading or becoming more painful; contact the treating team if worseningTrial descriptions do not set a universal number of days for recovery
Increased shedding across the scalpRecord onset, recent illness and medication changes for a prescriber or dermatology reviewTiming after an injection alone cannot establish a medication cause
A new smooth patch, broken hairs or inflamed scalpArrange an examination rather than assuming a specific type of alopeciaInclisiran studies do not quantify alopecia areata risk
Hives away from the injection site, facial swelling or breathing difficultySeek immediate medical help; breathing or swallowing difficulty requires emergency careA local injection-reaction percentage cannot estimate systemic allergy risk

Serious hypersensitivity reactions have been reported after marketing. Voluntary reports cannot establish how often they occur.[1] MedlinePlus identifies rash, hives, swelling and breathing or swallowing difficulty as symptoms requiring immediate attention.[7]

Evaluating hair changes

Hair loss can have overlapping causes, including hereditary thinning, illness, major stress, thyroid disease, nutritional problems and medications.[6] A dermatologist may examine the scalp, nails and other body hair, and ask how quickly the change developed. Blood tests or a scalp biopsy may be appropriate when the history and examination suggest a particular condition; there is no automatic test panel for everyone.[5] Avoid assuming a deficiency and starting supplements without an assessment.

Keep a record that helps the appointment

Write down each injection date and the date you first noticed a change. Describe whether hair is shedding diffusely or disappearing in patches, and note scalp itching, scale, tenderness or redness. Include recent illnesses, significant stress and medication or supplement changes.

Keep injection-site photographs separate from scalp photographs. Label both with dates; repeat scalp pictures using similar lighting, hair parting and distance. This gives the clinician a clearer timeline without turning photographs into a diagnostic test.

Discuss the symptoms before deciding about another dose. The decision should account for their severity, the suspected cause and your individual cholesterol-lowering benefit. Suspected medication-related shedding is a reason to contact the prescriber, rather than stop treatment on your own.[6]

Frequently asked questions

Does Leqvio (inclisiran) cause hair loss?

The cited evidence does not quantify a causal hair-loss rate. Its absence from the common-reaction table cannot rule out an association.[1]

What skin reactions does inclisiran cause?

Local pain, redness or swelling can occur. Rash, itching, hives or swelling away from the site need immediate medical attention; breathing or swallowing difficulty requires emergency care.[7]

How long do Leqvio injection-site reactions last?

There is no reliable universal duration. ORION-10 and ORION-11 described these reactions as generally mild, with none severe or persistent, but did not establish a recovery deadline for everyone. Ask the treating team about a reaction that worsens or is not improving.[2]

Is inclisiran associated with alopecia areata?

The cited trial evidence does not quantify an alopecia areata association. A new bald patch needs examination because several conditions can cause patchy loss.[2][5]

Can I continue Leqvio if I am experiencing hair thinning?

Discuss this with your prescriber before the next dose rather than making an automatic decision to continue or stop. The assessment should consider the hair-loss pattern, other possible causes, symptom severity and your expected cholesterol-lowering benefit. Do not stop a suspected medication on your own.[6]

Does inclisiran affect skin differently in women versus men?

The cited trial report does not establish separate hair-loss or skin-reaction risks for women and men. An individual change needs its own evaluation.[2]

How does the injection-site reaction rate for Leqvio compare to evolocumab or alirocumab?

The cited inclisiran trials were placebo-controlled, not head-to-head comparisons with evolocumab or alirocumab. Percentages from separate trials may reflect different populations, follow-up and reporting methods, so they cannot reliably rank these medicines by injection-site risk.[2]

Does Leqvio cause photosensitivity?

Photosensitivity is not quantified in this label. Report a new sun-associated rash, its timing, and other medication exposures.[1]

Can patients with psoriasis or eczema take inclisiran?

Ask your clinician about the affected skin and allergy history. The injection should avoid active rash, inflamed or infected skin.[1]

What should I tell my doctor if I notice hair changes on Leqvio?

Bring injection and symptom dates, dated photographs, and a description of diffuse shedding versus patches. Mention scalp symptoms, recent illness, stress and medication changes. The examination determines whether targeted blood tests or a biopsy would help; everyone does not need the same tests.[5][6]

Is Leqvio self-injected like other PCSK9 inhibitors?

Leqvio is given by a healthcare professional.[1]
