Modern Hybrid Approaches to Treatment Modern Hybrid Treatment Instead of strict rotation schedules, dermatologists tend to use more flexible strategies that are tailored to patients’ individual cases and response to therapies: Sequential Therapy With sequential therapy, your dermatologist may start off with a fast-acting treatment to quickly control severe symptoms, then transition you to a safer long-term option. For example, cyclosporine may be prescribed for a short period to stabilize a severe flare, while a biologic is introduced in parallel and takes effect over time, Adigun says.e60dc2a1-f33c-4a05-9b50-8e3e8e597629e7f0fd11-9ea1-491f-8993-58828ec19dca “If someone presents with severe disease, we may use something like cyclosporine because it works fast. Then you start the biologic at the same time and taper off the cyclosporine as the biologic has a chance to work,” she says. Combination Therapy vs Rotation Rather than switching treatments entirely, doctors may combine therapies to boost efficacy and yield better results in treating severe psoriasis.e60dc2a1-f33c-4a05-9b50-8e3e8e5976299b53a2e6-c074-4f4e-bd6e-b38d8033ab43 “We often use more flexible strategies, such as combination or sequential therapy, rather than rotation,” says Garshick. This might include pairing a systemic medication with a topical treatment or phototherapy to maintain control. Historically, combination therapy was used to enhance the effectiveness of older biologics when fewer options were available. “We would add methotrexate or phototherapy because we didn’t have other choices. Now we can switch to other biologics instead,” Adigun says. The “Washout” Period A short break, or “washout period,” between treatments may be recommended to reduce the risk of overlapping side effects.e60dc2a1-f33c-4a05-9b50-8e3e8e597629c289efa7-19b6-4fe1-9217-b92064db1f15 However, this isn’t always necessary and depends on the medications involved and the patient’s clinical situation, Adigun says. Instead, transitions are often more seamless, especially when patients are moving between biologics with different mechanisms of action, she says.
Rotational Therapy in the Age of Biologics Rotation and Biologics Biologics, which are targeted therapies that block specific parts of the immune system, have been game changers for psoriasis treatment, Garshick says. Unlike older drugs, biologics such as TNF inhibitors, IL-17 inhibitors, and IL-23 blockers target specific inflammatory pathways, rather than suppressing the immune system broadly. This makes them safer for continuous use in many patients.e60dc2a1-f33c-4a05-9b50-8e3e8e5976290f464121-5903-49f6-b83e-b3a86e60145d “They don’t carry the same toxicity risks as older systemic medications. While they do affect the immune system, they are generally considered safe for long-term use with appropriate monitoring, and many patients remain on them for years,” Garshick says. They’re also so effective that older therapies — the likes of methotrexate and cyclosporine — are used less, making rotational therapy in the traditional sense outdated, Adigun says. “We don’t do any of that anymore,” she says. “We have these other agents that are so much safer and so effective. Patients can be on them for years and years.” The latest biologics, especially IL-23 inhibitors, tend to work better and last longer than older treatments. People taking these newer biologics were much more likely to have clear or almost clear skin, and those results held up over time, according to research.e60dc2a1-f33c-4a05-9b50-8e3e8e5976290b3be839-56ca-41ed-a2f3-f53ece66c798 That said, treatment changes still happen but for different reasons. In some cases, patients may experience a loss of response over time or develop antibodies that reduce how well a biologic works. When this happens, switching therapies may be necessary, Garshick says. “In some cases, patients may need to switch biologics if they lose response over time or develop antibodies, but this is different from traditional rotational therapy and is more about optimizing efficacy rather than avoiding cumulative toxicity,” she says. One study found that 34 percent of people with psoriasis switched biologics within three years; in 72 percent of the time, loss of efficacy was the reason why, followed by adverse side effects.e60dc2a1-f33c-4a05-9b50-8e3e8e597629e5c14e68-c8db-4bb9-ac6f-d324a1bb9914
Why Rotation Is Used Why Rotation Is Used Before the advent of biologics , dermatologists relied on systemic treatments that had what is often called a “safety ceiling.” Rotational therapy became a tool to manage side effects and potential risks if these drugs were used in the long run, according to Marisa Garshick, MD , a dermatologist in New York and New Jersey and a clinical assistant professor of dermatology at NewYork-Presbyterian Weill Cornell Medicine. “Rotational therapy refers to cycling between different psoriasis treatments over time to help minimize potential risk of side effects from any single medication. It can be thought of as a way to maintain disease control while giving the body a break from certain therapies that may carry certain side effects,” Dr. Garshick says. Some of the most common examples include these drugs: Methotrexate A long-standing systemic therapy that can be highly effective, methotrexate is earmarked for severe, disabling psoriasis that isn’t responsive to topical therapies or phototherapy. Despite its efficacy, it’s associated with cumulative liver toxicity and requires ongoing monitoring and blood tests.e60dc2a1-f33c-4a05-9b50-8e3e8e597629d6b9ecac-84aa-4259-a7f6-616c60ee3a68 Cyclosporine Cyclosporine is a fast-acting immunosuppressant often used for severe flares, but it comes with potential risks, including kidney toxicity and elevated blood pressure when used long term.e60dc2a1-f33c-4a05-9b50-8e3e8e5976298f16600c-3cea-4983-872e-0dd7d421bfae Phototherapy Phototherapy slows rapidly growing skin cells, reduces inflammation, and suppresses an overly active immune system, but it has to be used sparingly. Ongoing UV exposure can increase the risk of skin aging and skin cancer over time.e60dc2a1-f33c-4a05-9b50-8e3e8e5976291888dafa-be29-4cf8-90fa-ff10bc73b4f1 Because of these safety ceilings, dermatologists historically rotated patients off one therapy and onto another, essentially giving one organ system a break while using a different treatment approach, says Chris Adigun, MD , a board-certified dermatologist in private practice in Chapel Hill, North Carolina. “We were monitoring kidney function, limiting duration, or switching [treatments] for a period of time. It was all about mitigating the systemic consequences of these drugs,” Dr. Adigun says. While this type of rotation is less common today, since systemic drugs aren’t used for long durations, a version of it still exists in everyday psoriasis care with topical treatments. “Typically, you’re rotating between topical steroids, which work fast and are effective, and steroid-sparing agents, which are less effective but don’t carry the same risks,” Adigun says. Topical steroids are often used to quickly bring flares under control, but because long-term or excessive use can lead to side effects like skin thinning, they’re not meant to be used continuously. Once symptoms improve, dermatologists transition patients to steroid-sparing treatments, such as vitamin D analogues or calcineurin inhibitors, which are safer for ongoing use.e60dc2a1-f33c-4a05-9b50-8e3e8e5976299ca9eb64-cc39-4ba3-9d81-343806d0578a “If you have a big flare, you’re not going to try and use those steroid-sparing agents, because they won’t be effective enough,” Adigun says. “But as you get that under control, you can switch to a steroid-sparing agent and use that more continuously.”
Navigating Treatment Change With Your Doctor Navigating Treatment Change For people living with psoriasis, open communication with your dermatologist is crucial, especially if your treatment plan isn’t working as expected or you’re unsure about the medication you’re on. Garshick recommends speaking up in these situations: Your current treatment isn’t controlling your symptoms. You’re experiencing side effects or tolerability issues. Lifestyle changes make your treatment difficult to maintain. You have questions or are worried about the long-term safety of your current treatment. “If a patient does not notice improvement, it is always good to check with their board-certified dermatologist to determine if results should be expected or if more time is needed. It’s good for patients to communicate openly. There are many options that can be considered if needed,” she says. Talk to your doctor if your treatment plan is unsustainable, Adigun says. You need a plan you can adhere to and that can fit into your life smoothly. “It really will depend on how diligent people are with their psoriasis. Some people, as soon as they’re flaring, they’re treating it right away, so they aren’t going to need that topical steroid for very long. Others wait until things are bad before they start treating,” she says. “It really can vary with how people are dealing with their chronic disease,” she says. It’s also important to know that if a treatment is working well, there may be no need to change it, especially with newer therapies. “If something is working, we don’t necessarily want to change it. Maintaining a stable, effective regimen is the goal,” she says, noting your doctor will discuss the next steps, such as a rotation, if you’re on systemic medications that have a time stamp to minimize side effects.
The Takeaway Rotational therapy involves switching treatments periodically over time to reduce long-term toxicity from older systemic drugs such as methotrexate and cyclosporine. With the rise of biologics, which are safe for long-term use, treatment changes are now less about limiting the risk of organ damage and more about maintaining effectiveness if a therapy stops working as well. Instead of rotating treatments on a set schedule to manage safety , dermatologists now use more flexible approaches like sequential or combination therapy to manage psoriasis over time. If your treatment isn’t working, is causing side effects, or doesn’t fit your lifestyle, talk to your doctor about adjusting your plan.
If you’re living with psoriasis , you may have noticed that your treatment plan changes over time — sometimes for the sake of safety and side effects, and sometimes because a treatment stops working as well as it used to. One term you might have come across while researching these changes is “rotational therapy.” This older strategy was once key to managing moderate to severe psoriasis. Rotational therapy is the practice of switching between different treatments — usually every 12 to 24 months — to reduce the risk of long-term side effects.e60dc2a1-f33c-4a05-9b50-8e3e8e5976294e8ac837-5f2f-4887-ba54-be1738f93e87 It was widely used before biologic therapies were introduced, when many psoriasis medications , namely older systemic drugs, could not be prescribed indefinitely because of increased risks to the liver, kidney, or other organs. But with biologic therapies in the picture, the landscape looks different. Newer therapies like biologics are designed for long-term use and don’t carry the same toxicity risks.e60dc2a1-f33c-4a05-9b50-8e3e8e597629fa0ed224-1089-4a5c-98d6-491388557597 However, rotating therapies and treatment changes haven’t disappeared entirely; they just happen for different reasons.
