Selective Co-Stimulation Modulators: Autoimmune Treatment Options
Introduction: Key Points on Selective Co-stimulation Modulators
Selective co-stimulation modulators are medications used to treat autoimmune conditions such as rheumatoid arthritis. These drugs target specific components of the immune system to reduce inflammation and prevent joint damage. They are often prescribed when other treatments have not been effective. If you have an autoimmune condition, selective co-stimulation modulators may help manage your symptoms. Consult one of our telemedicine providers to explore your treatment options.
Medications in the Selective Co-stimulation Modulators Drug Class
Abatacept (Abatacept)
Orencia (Abatacept)
The generic name is the official medical name of the drug, while the brand name is given by the manufacturer. The generic name is listed in parentheses.
How Do Selective Co-stimulation Modulators Work? Mechanism of Action
Selective co-stimulation modulators disrupt the communication between immune cells that contribute to inflammation. Specifically, they block the interaction between T-cells (a type of white blood cell) and other immune cells. Normally, T-cells require a “second signal” to become fully activated and trigger inflammation. These modulators prevent that second signal, reducing the immune system’s attack on the body’s tissues.
Abatacept, the primary medication in this class, binds to proteins on the surface of T-cells, preventing them from receiving the co-stimulatory signal. This action helps reduce inflammation and slow the progression of autoimmune diseases like rheumatoid arthritis.
Benefits of Co-stimulation Modulators in Autoimmune Diseases
Selective co-stimulation modulators are often used when other treatments, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or disease-modifying antirheumatic drugs (DMARDs), are not sufficient in controlling autoimmune conditions. These medications are particularly beneficial for patients with moderate to severe rheumatoid arthritis, helping to reduce pain, swelling, and long-term joint damage.
Compared to other drug classes, selective co-stimulation modulators offer a more targeted approach to treating autoimmune diseases. By focusing on specific immune pathways, they provide relief with fewer side effects than broader immune-suppressing drugs.

Potential Side Effects of Selective Co-stimulation Modulators
Like all medications, selective co-stimulation modulators can cause side effects. While not everyone will experience them, it’s important to be aware of the potential risks. Below is a list of side effects, starting with the most common and moving to less frequent ones. If you experience any side effects, especially severe ones, contact your healthcare provider immediately. You can also schedule a telemedicine appointment with one of our providers for guidance.
Common Side Effects (Greater than 1%)
Headache: Occurs in approximately 10-15% of patients. This is the most common side effect and is usually mild. If headaches persist or worsen, consult your doctor.
Upper respiratory tract infections: Occurs in about 9-12% of patients. Symptoms may include a runny nose, sore throat, or cough. Patients with a history of frequent infections may be at higher risk.
Nausea: Reported in 5-7% of patients. This side effect is generally mild and may improve over time. Eating smaller meals or avoiding spicy foods may help.
Fatigue: Affects around 3-5% of patients. If you feel unusually tired, it’s important to rest and stay hydrated. If fatigue becomes severe, contact your healthcare provider.
Fever: Occurs in about 2-4% of patients. Fever may indicate an infection or immune response. If you develop a fever, especially if it’s high or persistent, seek medical advice.
Joint pain (arthralgia): Affects 2-3% of patients. This can be managed with over-the-counter pain relievers, but if the pain is severe, consult your doctor.
Less Common Side Effects (Less than 1%)
These side effects are rare but can still occur. If you experience any of the following, contact your healthcare provider:
- Allergic reactions (rash, itching, swelling)
- Shortness of breath
- Chest pain
- Dizziness or fainting
- Increased risk of serious infections (e.g., pneumonia, tuberculosis)
- Autoimmune reactions (e.g., lupus-like syndrome)
- Liver enzyme abnormalities
Severe Side Effects
Although rare, some side effects can be serious. These include:
Severe infections: Selective co-stimulation modulators can suppress the immune system, increasing the risk of serious infections such as pneumonia or tuberculosis. If you develop a high fever, persistent cough, or difficulty breathing, seek medical attention immediately.
Allergic reactions: In rare cases, patients may experience severe allergic reactions, including swelling of the face, lips, or throat, difficulty breathing, or hives. This requires immediate medical attention.
Liver problems: Symptoms of liver issues include yellowing of the skin or eyes (jaundice), dark urine, or severe abdominal pain. If you notice any of these symptoms, contact your doctor right away.
Before starting treatment with selective co-stimulation modulators, it’s crucial to discuss your medical history with your healthcare provider. This will help identify any potential risks and ensure the medication is safe for you. If you have any concerns, schedule a telemedicine appointment with one of our providers to discuss your options.
Drug to Drug Interactions with Selective Co-Stimulation Modulators
Selective co-stimulation modulators can interact with other medications, potentially altering their effectiveness or increasing the likelihood of side effects. It’s important to inform your healthcare provider about all the medications you are taking, including over-the-counter drugs, supplements, and herbal products. Some known drug interactions include:
Immunosuppressants: Taking other immunosuppressive medications (e.g., methotrexate, corticosteroids) alongside selective co-stimulation modulators can raise the risk of infections. Your doctor may need to adjust your dosage or monitor you more closely to manage this risk.
Live vaccines: Because selective co-stimulation modulators suppress the immune system, live vaccines (e.g., measles, mumps, rubella, or yellow fever vaccines) should be avoided. These vaccines could lead to infections in individuals with weakened immune systems.
TNF inhibitors: Combining selective co-stimulation modulators with tumor necrosis factor (TNF) inhibitors (e.g., adalimumab, infliximab) significantly increases the risk of serious infections. This combination is generally not recommended.
Antibiotics: Certain antibiotics, such as rifampin, may reduce the effectiveness of selective co-stimulation modulators. If antibiotics are necessary, your doctor may need to adjust your treatment plan accordingly.
Precautions and Contraindications for Co-Stimulation Modulators
Before starting selective co-stimulation modulators, it’s essential to review your complete medical history with your healthcare provider. Certain conditions may increase the risk of side effects or make this medication unsuitable for you.
Precautions When Using Selective Co-Stimulation Modulators
Infections: Since selective co-stimulation modulators suppress the immune system, patients with a history of frequent or chronic infections should use this medication with caution. Your doctor may recommend additional monitoring or preventive measures to reduce the risk of infection.
Vaccinations: It’s important to ensure you are up to date on all vaccinations before starting treatment. Live vaccines should be avoided during treatment, as they can cause infections in individuals with suppressed immune systems.
Pregnancy and breastfeeding: The safety of selective co-stimulation modulators during pregnancy and breastfeeding is not well established. If you are pregnant, planning to become pregnant, or breastfeeding, discuss the potential risks and benefits with your healthcare provider.
Contraindications for Selective Co-Stimulation Modulators
Severe infections: Patients with active, severe infections should not begin treatment with selective co-stimulation modulators until the infection has been fully treated.
Allergic reactions: If you have a known allergy to selective co-stimulation modulators or any of their components, you should not take this medication.
Uncontrolled liver disease: Patients with severe liver disease may not be able to safely use selective co-stimulation modulators, as these medications can impact liver function.
Conclusion: Discussing Selective Co-Stimulation Modulators with Your Doctor
Selective co-stimulation modulators offer an effective treatment option for patients with autoimmune conditions, helping to reduce inflammation and manage symptoms.
