Understanding the Interaction: Savella and Buspirone
Taking Savella (milnacipran) and busPIRone together can lead to a significant drug interaction. Both medications affect serotonin levels in the brain. When combined, they can elevate serotonin to a potentially dangerous degree, increasing the risk of a rare but serious condition known as serotonin syndrome.
Savella is a serotonin and norepinephrine reuptake inhibitor (SNRI) approved by the FDA for the management of fibromyalgia. Buspirone is an anxiolytic (anti-anxiety) medication used for generalized anxiety disorder. Both drugs have serotonergic effects, making their concurrent use a known risk factor for serotonin syndrome. A healthcare provider may determine that the therapeutic benefits of using both drugs outweigh the risks for a specific patient, in which case they will take appropriate precautions and monitor the patient closely for any complications.
The Risk of Serotonin Syndrome
Serotonin syndrome occurs when there is an excessive amount of serotonin in the body. The risk is significantly higher when multiple serotonergic drugs are taken together. Symptoms can range from mild to life-threatening and often appear within hours of taking the combination.
Common symptoms include:
- Mental status changes like agitation or confusion.
- Autonomic instability, such as fast heart rate or changes in blood pressure.
- Neuromuscular symptoms like muscle spasms or tremors.
- Gastrointestinal issues, including nausea or diarrhea.
If you experience any of these symptoms while taking Savella and buspirone, seek immediate medical attention. Severe cases can be life-threatening.
Overview of Each Medication
Savella (Milnacipran)
- Primary Use: Management of fibromyalgia.
- Drug Class: SNRI.
- Common Side Effects: Nausea, headache, constipation, dizziness.
- Key Warnings: Boxed warning about increased risk of suicidal thoughts and behaviors in young adults. Can also increase blood pressure and heart rate.
Buspirone
- Primary Use: Management of anxiety disorders.
- Drug Class: Anxiolytic.
- Common Side Effects: Dizziness, nausea, headache, nervousness.
- Key Considerations: Lower potential for sedation and dependence than benzodiazepines. Grapefruit juice should be avoided.
| Feature | Savella (Milnacipran) | Buspirone |
|---|---|---|
| Primary Indication | Management of Fibromyalgia | Management of Anxiety Disorders |
| Drug Class | SNRI (Serotonin-Norepinephrine Reuptake Inhibitor) | Anxiolytic |
| Mechanism | Inhibits reuptake of serotonin and norepinephrine | High affinity for serotonin 5-HT1A receptors |
| Serotonergic Activity | Yes | Yes |
| Common Side Effects | Nausea, headache, constipation, increased heart rate, hypertension | Dizziness, nausea, headache, nervousness |
| Food Interaction | Can be taken with or without food; food may improve tolerability | Should be taken consistently, either always with or always without food |
Managing Fibromyalgia and Co-occurring Anxiety
Individuals with fibromyalgia often experience anxiety. An integrated treatment approach, combining pharmacology and non-pharmacological strategies, is often effective.
Non-Pharmacological Approaches:
- Cognitive Behavioral Therapy (CBT): Helps change negative thought patterns and is effective for chronic pain and anxiety.
- Exercise: Gentle exercise can reduce pain, improve sleep, and lessen stress and depression.
- Stress Management: Techniques like mindfulness and deep-breathing exercises can help manage stress.
- Sleep Hygiene: Establishing a regular sleep schedule is important for improving sleep quality.
Conclusion: Prioritize a Doctor's Guidance
Combining Savella and buspirone carries a significant risk of serotonin syndrome. This combination should only be used under close medical supervision if a doctor determines the benefits outweigh the risks. Always inform your healthcare provider of all medications and supplements you are taking to prevent dangerous interactions. Open communication with your doctor is crucial for a safe and effective treatment plan.
