Eucrisa may cause several side effects. Here are some frequently asked questions about the drug’s side effects and their answers.

Does Eucrisa come in cream form? If so, what are its side effects?

No, Eucrisa is available only as an ointment that you apply to your skin. It isn’t made in a cream form.

The difference between a cream and an ointment is the ratio of water and oil they contain. Creams contain more water and ointments contain more oil. Creams easily absorb into the skin while ointments are designed to protect your skin against moisture loss by staying on top of your skin. Since atopic dermatitis commonly causes dry skin, ointments can be beneficial for this condition.

But other atopic dermatitis treatments are available in cream form. A few examples of steroid-free prescription creams include pimectolimus (Elidel), ruxolitinib (Opzelura), and doxepin (Zonalon). Also, several corticosteroids, such as hydrocortisone, are available as creams and may help relieve atopic dermatitis symptoms.

If you’re interested in trying Eucrisa or an atopic dermatitis medication that comes as a cream, talk with your doctor. They can advise you on which treatment options are best for you.

Is cancer a side effect of Eucrisa?

Eucrisa isn’t known to cause cancer. There weren’t any cases of cancer reported in the drug’s clinical trials or since the Food and Drug Administration (FDA) approved it in 2016.

However, other atopic dermatitis treatments, such as pimecrolimus cream (Elidel) and tacrolimus ointment (Protopic), have been linked to cancer. These medications have boxed warnings due to rare reports of skin cancer or lymphoma (a type of blood cancer) with long-term use. A boxed warning is the strongest warning required by FDA.

If you have concerns about Eucrisa or developing cancer, talk with your doctor. They can discuss the risks and benefits of treatment with Eucrisa.

Does Eucrisa cause hair loss?

No, Eucrisa shouldn’t cause hair loss. This side effect did not occur during clinical trials of the drug.

Atopic dermatitis can make your areas of your skin dry and itchy. If atopic dermatitis affects your scalp, it’s possible that excessive scratching can lead to hair loss.

Talk with your doctor for ways to relieve scalp itching or to check for other causes of hair loss.

Burning or stinging sensation

Eucrisa may cause pain or discomfort at the areas where the ointment is applied. Symptoms include a temporary stinging or burning sensation.

This was the most common side effect reported in the drug’s clinical trials, and it only affected a small percentage of people. In most cases, the pain, stinging, or burning from using Eucrisa went away within 1 day.

What you can do

Any pain, stinging, or burning that occurs after applying Eucrisa should be temporary.

It’s important to apply Eucrisa ointment only to the areas of your skin affected by atopic dermatitis. You should not apply the ointment to your eyes or mouth. Eucrisa should also not be applied to the vagina.

If these feelings of pain, stinging, or burning become severe, wash Eucrisa off the area right away and talk with your doctor. They may recommend stopping your use of the medication until the discomfort goes away. They may also recommend switching to a different atopic dermatitis treatment.

Allergic reaction

As with most drugs, Eucrisa can cause an allergic reaction in some people.

Symptoms of an allergic reaction to Eucrisa can appear at the application sites (areas where the ointment is put on the skin). Or they can occur at other skin areas, distant from applications sites.

Symptoms can be mild or serious and can include:

  • skin rash
  • hives
  • severe itchiness
  • flushing
  • swelling under your skin, typically in your lips, eyelids, feet, or hands
  • swelling of your mouth, tongue, or throat, which can make it hard to breathe

What you can do

For mild symptoms of an allergic reaction, call your doctor right away. They may recommend ways to ease your symptoms and determine whether you should keep taking Eucrisa. But if your symptoms are serious and you think you’re having a medical emergency, immediately call 911 or your local emergency number.

Be sure to talk with your doctor about your health history before you take Eucrisa. This drug may not be the right treatment for you if you have certain medical conditions or other factors that affect your health. The conditions and factors to consider include:

Allergic reaction. If you’ve had an allergic reaction to Eucrisa or any of its ingredients, including petrolatum (Vaseline), your doctor will likely not prescribe Eucrisa. Ask your doctor what other medications may be better options for you.

Alcohol use with Eucrisa

Eucrisa is a medicated ointment that you’ll apply to your skin. Drinking alcohol doesn’t affect it.
