The Consumer’s Guide to Biologics for Hidradenitis Suppurativa
T reating hidradenitis suppurativa (HS) isn’t always easy, especially for people with moderate-to-severe cases. Currently, there’s only one type of medication — a class of drugs called biologics — that’s approved by the U.S. Food and Drug Administration (FDA) to treat HS.
Biologics have been used to treat other inflammatory conditions, such as rheumatoid arthritis and psoriasis, for decades. Even so, they can still feel new to people with HS who are considering biologics for the first time.
Use this guide to learn more about how the drugs work, how they can treat the condition, and whether they’re right for you.
How Biologics Work for HS
How Biologics Are Transforming HS Treatment
Prior to 2014 there were no FDA-approved medications to treat HS. Since then, four biologics have been approved for treating HS specifically.
These drugs already have long track records for treating other chronic inflammatory autoimmune conditions, such as psoriasis, rheumatoid arthritis, and ulcerative colitis. But adding HS to the indication list has been groundbreaking for the treatment of this skin disease.
That said, many other types of treatment have been and continue to be used to control skin lesions and reduce the discomfort of HS. These include NSAIDs, antibiotics, corticosteroids, retinoids, and surgery to drain or remove abscesses.
But biologics work differently: They block the underlying inflammatory process before it even begins.
“Biologics have really become one of the best ways to target the immune system to improve disease states and also to minimize complications of oversuppressing your immune system,” says Iltefat Hamzavi, MD, a physician at Hamzavi Dermatology and Henry Ford Hospital in Detroit.
7 Essential Facts About Biologics for HS
Learning more about biologics can help you feel more comfortable with them as a treatment option for hidradenitis suppurativa.
1. Four biologics have been approved to treat HS.
These medications include:
- adalimumab (Humira)
- bimekizumab-bkzx (Bimzelx)
- infliximab (Remicade)
- secukinumab (Cosentyx)
More approvals may be coming down the pike.
Each type of biologic targets a specific protein thought to play a role in triggering the inflammation that contributes to HS.

2. Biologic drugs are typically prescribed for moderate-to-severe HS.
Your treatment options will depend on the severity of HS, which is classified by stage, called Hurley stages:
- Stage 1 (mild): You have one or a few lesions in one area of your body.
- Stage 2 (moderate): Nodules get bigger and may appear in more than one area of your body. You may experience some scarring or tunneling.
- Stage 3 (severe): You have widespread abscesses with extensive scarring or tunneling and chronic pain.
Stage 1 HS may be managed with warm compresses, antibacterial or antiseptic washes, or NSAIDs. For stages 2 and 3, your doctor may prescribe antibiotics, corticosteroids, retinoids, hormone therapy, or biologics. “When you have a lot of new nodules and have tried other treatments, that’s when you should consider a biologic,” says Dr. Hamzavi.

3. Biologics are administered by injection or infusion.
Adalimumab, bimekizumab-bkzx, and secukinumab are self-injected at home. Infliximab is administered as an infusion at a hospital or clinic.
“Different options are given at different intervals,” says Maria Aleshin, MD, a clinical associate professor of dermatology and the director of the HS clinic at Stanford Medicine in Emeryville, California. Depending on the drug, you may need to take it weekly, every other week, monthly, or once every two months.

4. Most people can expect to see some improvement in three months.
You may start to notice some improvement in symptoms after three months. “But we really want to stick it out to about the six-month mark to make sure we understand the maximum benefits that you’re able to get from this medication,” says Haley Naik, MD, vice president of the Hidradenitis Suppurativa Foundation and a dermatologist at the University of California in San Francisco.
Because biologics can take a bit of time to start kicking in, “Some dermatologists will prescribe additional therapy, like an antibiotic, to help bridge the gap until the biologic starts working,” says Dr. Aleshin.

5. Biologics are effective but may not work for everyone.
Biologics are pioneers when it comes to HS treatment. “This is a disease for which really no good treatments existed for many decades,” says Dr. Naik. “Biologics have completely changed the way we treat HS and are more effective than any previous treatment we’ve used to treat this disease.”
The caveat is that they don’t work for everyone. “For some, a biologic can be incredibly effective. For others, it can be partially effective,” she adds. “The main takeaway is that it’s hard to predict how you’re going to respond to biologics unless you try them.”

6. Biologics are considered safe but come with potential side effects.
Each type of biologic has its own unique set of risks and side effects. The most common are pain and redness at the injection site and cold or flu-like symptoms. Because biologics work by suppressing the immune system, they may increase your risk of infection. They also come with a very low risk of certain types of cancer. And biologics may reactivate latent tuberculosis or hepatitis B or C infections, so you’ll need to be tested for those before starting a biologic.
That said, studies have shown that these biologics are safe, effective, and well tolerated and provide meaningful results for people with HS.

7. They’re expensive, but you have options for coverage and financial assistance.
Biologics can cost $10,000 to $30,000 a year — and potentially in excess of $500,000 a year for the most expensive ones. The good news: Those that have been approved by the FDA for HS are usually covered by insurance, says Aleshin.
You may still have out-of-pocket costs, but how much you’ll need to pay depends on your insurance plan. If you have trouble getting insurance approval or are concerned about paying for a biologic, talk to your doctor, who can help you find a solution that meets your insurance and treatment needs. They can also discuss your financial assistance options, such as patient assistance programs that some pharmaceutical companies offer to help lower the cost of medication.

Is It Time to Try a Biologic for HS?
Your dermatologist will likely recommend trying other treatment options before starting you on a biologic. These may include:
- Topical or systemic antibiotics, which can help treat infected lesions. “These are considered to be first-line therapy for HS,” says Naik.
- Topical cleansing products, combined with warm baths or compresses and good hygiene, which can help heal wounds and reduce the risk of infection
- NSAIDs, which can help alleviate pain
- Hormone therapy, to address the possibility that HS may be caused by a hormonal imbalance
- Corticosteroids, which can help reduce inflammation and relieve symptoms
- Retinoids, or acne medications, to clear up the skin
“Biologics are intended for people who have more moderate-to-severe HS that has not been responsive to first-line treatment,” Naik explains.
If you’re having trouble controlling your HS, talk to your dermatologist. Together, you can come up with the right treatment — or combination of treatments — that can help. “It’s important to have a good relationship with a dermatologist who knows about you and your overall health in order to help you make good decisions about biologic treatment,” she adds.
