What is Skyrizi?

Skyrizi® (risankizumab-rzaa) is a prescription biologic medicine used to treat certain inflammatory conditions. It works by targeting inflammation in the immune system.

It is used in moderate to severe plaque psoriasis, psoriatic arthritis, Crohn’s disease, and ulcerative colitis.

Important safety point before treatment

Before starting Skyrizi, patients are typically screened for tuberculosis because the medicine can potentially activate or worsen existing infections.

Anyone with a history of infections or other health concerns should discuss them with their healthcare provider before treatment begins.

How long do Skyrizi side effects last?

The length of side effects can vary from person to person. Mild effects such as injection site reactions or headaches may last a few days to a week.

More serious side effects may last longer and need medical review. If symptoms persist or worsen, a healthcare professional should be contacted.

In clinical studies, many reported side effects improved within about a month of treatment initiation, but monitoring remains important.

Common side effects of Skyrizi

Commonly reported side effects include:

  • Upper respiratory infections
  • Headache
  • Injection site reactions

These effects are generally described as mild and often resolve without additional treatment.

Skyrizi side effects: hair loss

Some patients report hair loss after starting Skyrizi, but this is not experienced by everyone.

If hair thinning or patchy hair loss occurs, it may be temporary. It can also be difficult to know whether the cause is the medicine, the underlying condition, or another factor.

  • Tell your healthcare provider if you notice significant hair changes.
  • Ask whether any other causes should be checked.
  • Keep follow-up appointments so changes can be monitored.

What are the serious side effects of Skyrizi?

Although Skyrizi is generally well tolerated, serious side effects can occur. These may include allergic reactions, liver damage, and severe infections.

Possible warning signs can include difficulty breathing, unusual bruising, bleeding, or other concerning symptoms. Prompt medical attention is important if these occur.

Regular check-ups may be recommended so your healthcare team can monitor your overall health during treatment.

Skyrizi side effects and cancer concerns

Questions about cancer risk sometimes come up with biologic medicines. The current content does not show a definitive link between Skyrizi and increased cancer risk.

People with a history of cancer or other risk factors should discuss their individual situation with a healthcare professional and keep up with recommended screenings.

Skyrizi side effects reviews: what patients say

Patient experiences are mixed. Many people report improvement in skin or joint symptoms, with side effects such as mild fatigue or headaches that are manageable.

Others report more troublesome effects, which is why ongoing communication with a healthcare team matters.

  • Some patients report fewer psoriasis plaques.
  • Some report better day-to-day quality of life.
  • Individual experiences can differ widely.

Skyrizi side effects in Crohn’s disease

For Crohn’s disease, Skyrizi may help reduce inflammation and improve symptoms such as abdominal pain and diarrhea.

Some patients also notice changes in bowel habits or abdominal discomfort. Any new or worsening symptoms should be discussed with a healthcare professional.

Skyrizi side effects and weight gain

Weight gain is not typically described as a direct side effect of Skyrizi in the current content.

However, changes in appetite, activity level, or overall health can affect weight over time. If weight changes are a concern, they should be reviewed with a clinician.

  • Track weight changes over time.
  • Note any changes in appetite or activity.
  • Discuss concerns during routine follow-up.

What to discuss with your doctor or pharmacist

Because Skyrizi is a prescription biologic, it is important to confirm the details of your treatment plan with a healthcare professional or pharmacist.

Useful questions include:

  • What condition is Skyrizi being used to treat in my case?
  • What side effects should I watch for?
  • What infection screening or monitoring is needed?
  • What should I do if I miss a dose or have a reaction?
