Evrysdi (Generic Risdiplam): Complete Medication Guide
Key Takeaways
Evrysdi is a liquid medication that treats spinal muscular atrophy (SMA) by helping the body make more survival motor neuron (SMN) protein.
It's taken by mouth once daily and can be mixed into food or drinks for easier administration.
Common side effects include upper respiratory infections, fever, and rash; serious side effects are rare but require immediate medical attention.
The generic version works the same way as the brand-name drug but costs significantly less.
Always take Evrysdi exactly as prescribed and discuss any concerns with your healthcare provider.
Evrysdi Overview
Evrysdi (generic risdiplam) is an oral medication used to treat spinal muscular atrophy (SMA) in patients of all ages, including infants. SMA is a genetic disorder that weakens muscles over time by affecting nerve cells that control movement. This medication works by helping your body produce more survival motor neuron (SMN) protein, which supports the health of motor neurons—the nerve cells responsible for muscle control.
The generic version of Evrysdi contains the same active ingredient as the brand-name medication and works identically in your body. Generic vs Brand Name Drugs are regulated by the FDA to ensure they're equally safe and effective. Since it's approved for all age groups, Evrysdi can be prescribed from infancy through adulthood, making it an important treatment option for families managing SMA.

Side Effects
Most people tolerate Evrysdi well, though some experience mild side effects. Your body may adjust to the medication over time, and many side effects improve with continued use.
Common Side Effects
Upper respiratory infections — Common viral or bacterial infections of the nose, throat, and upper airways; may cause cough, congestion, or sore throat.
Fever — Temporary increase in body temperature, often mild and occurring shortly after starting the medication.
Rash — Skin irritation or bumps that may appear on various parts of the body; usually mild and resolve without treatment.
Constipation — Difficulty having bowel movements or infrequent stools; staying hydrated and eating fiber-rich foods may help.
Vomiting or nausea — Stomach upset or urge to vomit; taking the medication with food may reduce these symptoms.
Diarrhea — Loose or watery stools; staying hydrated is important during this side effect.
Serious Side Effects
Severe allergic reaction — Difficulty breathing, swelling of the face or throat, or severe rash; requires immediate emergency care.
Signs of infection — High fever, chills, severe fatigue, or persistent cough may indicate a serious infection requiring medical evaluation.
Liver problems — Yellowing of skin or eyes, dark urine, or severe abdominal pain; these are rare but serious and need urgent attention.
Abnormal bleeding or bruising — Unexplained bruises, nosebleeds, or bleeding from gums may signal a blood-related concern.
Severe skin reactions — Blistering rash, peeling skin, or widespread skin irritation; stop the medication and seek immediate care.
When to Seek Medical Attention
Contact your doctor right away if you develop signs of a serious allergic reaction, such as difficulty breathing, severe swelling, or a widespread rash. If you notice symptoms of infection—including high fever, chills, or severe fatigue—call your healthcare provider, especially since SMA patients may be more vulnerable to infections.
Seek emergency care if you experience yellowing of the skin or eyes, dark urine, severe abdominal pain, or unexplained bleeding. These symptoms may indicate serious side effects that need urgent evaluation. Don't wait to report any new or worsening symptoms to your medical team.

Drug Interactions
Evrysdi may interact with certain medications and substances, potentially reducing its effectiveness or increasing side effects. Always inform your healthcare provider about all medications, supplements, and herbal products you're taking.
Strong CYP3A4 Inhibitors (Ketoconazole, Itraconazole)
These medications can increase Evrysdi levels in your body, potentially causing stronger side effects. Your doctor may need to adjust your Evrysdi dose or monitor you more closely if you take these antifungal medications.
Strong CYP3A4 Inducers (Rifampin, Phenytoin)
These drugs can decrease Evrysdi effectiveness by lowering its levels in your blood. Your healthcare provider may increase your Evrysdi dose or choose an alternative medication if you need these inducers.
Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)
Regular use of NSAIDs like ibuprofen or naproxen may increase stomach irritation when combined with Evrysdi. Use the lowest effective dose and take NSAIDs with food, or ask your doctor about safer pain relief options.
Live Vaccines
Evrysdi may affect how well live vaccines work in your body. Discuss any planned vaccinations with your healthcare provider before starting or continuing Evrysdi treatment.
Anticoagulants (Blood Thinners)
Evrysdi may increase bleeding risk when taken with anticoagulants like warfarin. Your doctor will monitor blood clotting and may adjust medication doses as needed.
Aspirin and Salicylates
Regular aspirin use may increase the risk of bleeding or stomach problems. Talk to your doctor about safe pain relief options while taking Evrysdi.
