Hydroxychloroquine (HCQ) is a common initial treatment for Sjögren's syndrome, often used to manage symptoms like joint pain, fatigue, and rashes. However, it may not be effective for all patients, and some may experience side effects or need a stronger therapy. When HCQ proves insufficient, a healthcare provider may explore other medication classes to control the autoimmune response and alleviate symptoms.
Systemic Disease-Modifying Agents
Beyond hydroxychloroquine, several other disease-modifying antirheumatic drugs (DMARDs) and biologics can target the underlying inflammation and overactive immune system in Sjögren's syndrome.
Conventional DMARDs
For patients with significant joint or muscle pain who do not respond to HCQ, other conventional DMARDs may be considered.
- Methotrexate (Trexall®, Rheumatrex®): This immunosuppressant is used to treat inflammatory joint pain associated with Sjögren's syndrome. It is often prescribed when HCQ is ineffective. However, it is a potent medication with a different side effect profile than HCQ and requires regular monitoring by a rheumatologist.
- Leflunomide (Arava®): This DMARD can be an option if HCQ or methotrexate alone are not effective for inflammatory musculoskeletal pain. It modifies immune system activity and is also used for other autoimmune conditions.
- Azathioprine (Imuran®) and Mycophenolate Mofetil (Cellcept®): These more potent immunosuppressants are reserved for more severe cases of Sjögren's, particularly those with major organ involvement such as the lungs or kidneys.
Biologics
Biologic therapies target specific components of the immune system and are typically reserved for patients with severe systemic complications.
- Rituximab (Rituxan®): This medication targets and depletes B-cells, which are overactive in Sjögren's. It is used for specific severe manifestations, including vasculitis, lymphoma, and severe parotid swelling. It is administered via intravenous (IV) infusion.
- Belimumab (Benlysta®): Another B-cell modulating therapy, belimumab has shown promise for certain autoimmune conditions and is sometimes used in Sjögren's, although it is not specifically FDA-approved for this condition. It can be administered as an IV infusion or a subcutaneous self-injection.
Symptom-Specific Medications
For many patients, especially those who primarily experience dryness, treatment focuses on managing the specific symptoms of dry eyes and dry mouth.
Dry Eye Treatment
- Prescription Eye Drops: For moderate to severe cases, ophthalmologists can prescribe anti-inflammatory drops like cyclosporine (Restasis®, Cequa™) or lifitegrast (Xiidra®), which help decrease inflammation in the tear glands to increase tear production.
- Punctal Plugs: These tiny, dissolvable or permanent plugs are inserted into the tear ducts to block drainage and keep natural tears on the eye's surface longer.
- Other Options: In severe cases, autologous serum eye drops (made from a patient's own blood) can help heal surface damage.
Dry Mouth Treatment
- Cholinergic Agonists: Oral medications like pilocarpine (Salagen®) and cevimeline (Evoxac®) stimulate the salivary glands to produce more saliva and can also benefit dry eyes. Side effects can include increased sweating and nausea.
- Artificial Saliva: Numerous over-the-counter products are available to help moisten and lubricate the mouth.
Corticosteroids and NSAIDs
- Corticosteroids (e.g., prednisone): These powerful anti-inflammatory drugs are used for short-term management of severe flare-ups, such as significant joint pain or inflammation. Due to significant side effects with long-term use, doctors aim to use them for the shortest possible duration at the lowest effective dose.
- Non-steroidal Anti-inflammatory Drugs (NSAIDs): Over-the-counter NSAIDs like ibuprofen or naproxen can help manage mild joint pain. They can be combined with other therapies for greater effect.
Comparison of Sjögren's Medications
Medication Type | Examples | Primary Target Symptoms | Administration | Key Considerations |
---|---|---|---|---|
DMARDs | Methotrexate, Leflunomide | Joint pain, systemic inflammation | Oral | Require regular monitoring; different side effect profiles |
Biologics | Rituximab, Belimumab | Severe systemic manifestations (e.g., vasculitis) | IV Infusion, Subcutaneous | Potent immune suppression; reserved for severe cases |
Cholinergic Agonists | Pilocarpine, Cevimeline | Dry mouth, dry eyes | Oral | Stimulate secretions; common side effect is sweating |
Prescription Eye Drops | Cyclosporine, Lifitegrast | Moderate to severe dry eyes | Ophthalmic drops | Anti-inflammatory; can take weeks to months for full effect |
Corticosteroids | Prednisone | Acute flares, severe inflammation | Oral | Quick-acting; used short-term due to side effects |
Investigational Treatments
Ongoing research continues to develop new targeted therapies for Sjögren's. One promising investigational drug is nipocalimab, an FcRn blocker that reduces levels of inflammatory IgG autoantibodies. It has been granted FDA Breakthrough Therapy designation for moderate-to-severe Sjögren's disease. While not yet available, such developments offer hope for future treatment options.
Conclusion
For individuals with Sjögren's syndrome who need to find an alternative to hydroxychloroquine, a wide array of options exist. The appropriate medication depends on the specific symptoms, disease severity, and individual patient factors. Whether exploring a different DMARD like methotrexate, a biologic such as rituximab for systemic issues, or symptom-specific treatments like pilocarpine or cyclosporine eye drops, effective management is possible. The most crucial step is to work closely with a rheumatologist to develop a personalized treatment plan.
