HS Biologics: 2026 Choices for Better Comfort

If you have hidradenitis suppurativa (HS), you know the path to getting it under control means trying a lot of different things. Biologic therapies are a huge step forward because they target the specific inflammation that causes HS. Figuring out which biologic is right for you, and what goes into that decision, can completely change your day-to-day comfort and how the disease progresses. To work through the options, you have to understand how they work, what they can do for you, and if they fit your specific health situation. We’re aiming for sustained remission and a life that isn’t dictated by your HS.

1. Understand Your HS Severity and Phenotype

First thing’s first: you and your doctor have to get a really accurate picture of your hidradenitis suppurativa (HS) severity and its specific type, or phenotype. HS isn’t the same for everyone. It looks and feels different from person to person, which changes how well treatments work. Dermatologists use the Hurley Staging system (I, II, and III) to get a handle on severity. Stage I is just isolated abscesses, no tunnels or scars. Stage II means you’re getting recurrent abscesses with some sinus tracts and scarring. Stage III is the most severe, with widespread, interconnected tunnels and scarring across large areas. Your doc will also look at where your lesions are (armpits, groin, butt), how often you flare, and how much pain or drainage you have. Someone with Stage III everywhere is obviously going to need a different, more aggressive biologic plan than someone with Stage II in just one spot.

We’re also learning that just looking at the stage isn’t enough. Your specific HS “phenotype” matters a lot. Do you have mostly big, angry inflammatory nodules, or is your disease more about deep tunnels and scarring? These details help point to the right biologic. For instance, if you’re dealing with a ton of inflammation, a tumor necrosis factor-alpha (TNF-alpha) inhibitor might be the ticket. But if you have more of the hard, fibrotic scarring, a different drug targeting another pathway might be better. There was even a 2024 study in the Journal of the American Academy of Dermatology that confirmed this, showing that matching the drug to the patient’s dominant inflammatory type could really boost how well people respond.

2. Review Prior Treatment Responses and Failures

What you’ve already tried is a goldmine of information for picking a biologic. Think about it: have you been on oral antibiotics? Topicals? Steroid injections? And what happened? Did you get a little better, or did nothing change at all? It’s so important to write all this down, what you took, for how long, and any side effects. If you’ve already been through several rounds of different antibiotics and maybe even oral retinoids with no luck, that’s a huge sign that the inflammation is deep and it’s time to bring in a biologic.

We need to be clear about what “failing” a treatment means. It doesn’t have to mean it did absolutely nothing. It could mean the improvement wasn’t good enough, or the side effects were just too much to handle. Maybe doxycycline cut down your flares a bit, but you’re still in pain and getting new spots. That’s a perfect case for adding or switching to a biologic. On the other hand, if you had a bad allergic reaction to a systemic drug, your doctor knows to avoid that whole class of medication. Your dermatologist is looking at this entire track record. The American Academy of Dermatology guidelines even say that if first-line systemic antibiotics don’t get moderate HS under control after a few months, it’s time to start talking about biologics.

3. Assess Comorbidities and Contraindications

HS rarely travels alone. It often shows up with other health problems (comorbidities) that will definitely affect which biologic is right for you. We’re talking about things like metabolic syndrome, inflammatory bowel disease (like Crohn’s), arthritis, depression, and anxiety. There’s an upside here: some biologics, especially TNF-alpha inhibitors, are also used for IBD. If you’re unlucky enough to have both HS and Crohn’s, you can sometimes kill two birds with one stone by picking a drug that treats both. But the reverse is also true, some biologics are a bad idea if you have other issues, like a history of bad infections or a neurological disorder, and would need extra-careful monitoring.

Expect a full workup from your doctor before you start. They’ll take a deep dive into your medical history and order some screening tests. This will almost certainly include a test for tuberculosis, since some biologics can wake up a latent TB infection, along with hepatitis B/C screening. If you have a history of congestive heart failure, a demyelinating disease like multiple sclerosis, or certain cancers, that’s going to heavily influence which biologic is safe for you, or if any are safe at all. It’s all about getting the most good out of the drug with the least possible risk. The National Institutes of Health has a ton of info on the safety records of these drugs if you want to dig in yourself.

4. Discuss Biologic Mechanisms and Target Pathways

So how do these drugs actually work? Biologics go after the specific inflammatory signals that drive HS. You don’t need a PhD in immunology, but knowing the basics will help you have a much better conversation with your dermatologist. Right now, the main biologics for HS go after one of two things: either TNF-alpha or the IL-17/IL-23 pathways.

• TNF-alpha Inhibitors: Adalimumab (Humira) is the old guard for HS biologics. It specifically blocks TNF-alpha, which is a major inflammatory protein that basically fuels the fire in HS lesions. For a lot of patients, especially those whose HS is very red and angry (inflammatory), a TNF-alpha inhibitor works wonders to bring down the number of spots and the pain.
• IL-17/IL-23 Inhibitors: Then you have other options like secukinumab (Cosentyx) and guselkumab (Tremfya) that hit different targets. Secukinumab blocks a cytokine called IL-17A, another bad actor in chronic inflammation. Guselkumab goes after the p19 subunit of IL-23. These are completely different pathways from TNF-alpha, so they give us great alternatives for people who didn’t get better on a TNF-alpha blocker or who have other health issues. For instance, if a TNF-alpha drug did nothing for you, or if you also have psoriatic arthritis (which responds well to IL-17 drugs), one of these might be a much better fit.

Every biologic is different in terms of its side effect profile and how you take it. Some are shots you give yourself at home every week, or every two weeks, or once a month. Others are IV infusions at a clinic. Your doctor will walk you through all of this so you can weigh the pros and cons for your own life. It’s about more than just what works best on paper, it’s about what you can actually stick with for the long haul.

5. Discuss Potential Side Effects and Monitoring

All drugs have potential side effects, and biologics are no different. They’re usually well-tolerated, but you absolutely need to have a frank talk with your doctor about what you might experience and what to watch out for. The common stuff is usually minor: some redness, swelling, or itching where you do the injection, and maybe you’ll catch more colds (upper respiratory infections). The more serious risks are rare, but you need to know about them: things like reactivating an old infection (like TB), triggering a new autoimmune problem, or a slight increase in risk for certain cancers.

Before your first dose, your doctor will lay out a monitoring schedule. You’ll have regular blood work to keep an eye on your liver, kidneys, and blood counts. They’ll also give you a list of “call me immediately” symptoms, things like a fever that won’t go away, losing weight without trying, or any new nerve symptoms. You have to tell your doctor about anything new or weird that pops up. It’s the most important part of staying safe on these meds. The U.S. Food and Drug Administration (FDA) has all the detailed safety info for every biologic if you want to read the fine print.

6. Set Realistic Expectations and Plan for Follow-Up

A biologic isn’t a magic bullet for HS. You’re going to need patience and you have to be consistent with your doses. It’s really important to have a realistic timeline in your head. A few people might feel better in a few weeks, but for most, it takes several months to really see a big difference, and you might continue to improve for a year or even longer. Your doctor should work with you to set concrete goals, like getting the number of lesions down, lowering your pain score, and being able to do more of the things you enjoy, and you’ll check in on those goals at every follow-up.

You have to go to your follow-up appointments. This is non-negotiable. Your dermatologist needs to see you to track how you’re responding, check for side effects, and tweak the plan if needed. That could mean upping your dose, changing how often you take it, or switching to a new biologic altogether if the first one isn’t cutting it. HS is a long-term game, and managing it is a process that changes as you go. Keeping an open line of communication with your medical team about how you’re doing is the only way to succeed in the long run. Once you’re stable, you’ll probably have appointments every three to six months, but they’ll be more frequent at the start.

Choosing the right biologic for hidradenitis suppurativa is a team effort between you and your dermatologist. It’s based on a solid understanding of your specific disease, your health history, and what drugs are out there. If you jump in, ask questions, and keep talking to your doctor, you give yourself the best shot at finally getting some lasting relief and control over your HS.
