Signs and Symptoms of Lyrica (Pregabalin) Withdrawal
Abrupt discontinuation of Lyrica (pregabalin) can cause significant withdrawal symptoms including insomnia, nausea, headache, anxiety, hyperhidrosis, and diarrhea, which can be prevented by gradually tapering the medication over at least one week. 1
Common Withdrawal Symptoms
Pregabalin withdrawal manifests through several distinct symptom categories:
Neuropsychiatric Symptoms
- Insomnia
- Anxiety
- Headache
- Irritability
- Restlessness
- Visual hallucinations (in severe cases)
- Confusion
Gastrointestinal Symptoms
- Nausea
- Diarrhea
- Vomiting
- Decreased appetite
Autonomic Symptoms
- Hyperhidrosis (excessive sweating)
- Tachycardia
- Hypertension
- Fever
Other Physical Symptoms
- Tremors
- Muscle pain/aches
- Piloerection (goosebumps)
- Seizures (in severe cases)
Risk Factors for Withdrawal
The severity of pregabalin withdrawal depends on several factors:
- Duration of use: Patients using pregabalin for more than 14 days are at higher risk for withdrawal symptoms 2
- Dosage: Higher doses create greater risk for withdrawal severity
- Abrupt discontinuation: Stopping suddenly rather than tapering increases risk significantly
- Individual factors: Patient metabolism and physiology affect withdrawal intensity
Important Clinical Considerations
Timing of Withdrawal Onset
Withdrawal symptoms typically begin within 24-48 hours after the last dose and may persist for up to 7 days in most cases. However, some patients experience a protracted withdrawal syndrome that can last longer 3.
Severity Assessment
The Clinical Opiate Withdrawal Scale (COWS) can be adapted to monitor pregabalin withdrawal severity, though it's not specifically designed for pregabalin 2. Monitoring vital signs and patient-reported symptoms is essential.
High-Risk Scenarios
- Patients with history of substance use disorders
- Concurrent discontinuation of other CNS depressants
- Patients with seizure disorders (increased seizure risk during withdrawal)
Prevention and Management
Tapering Protocol
- Gradually reduce pregabalin by 10-20% of the original dose every 24-48 hours 2
- For patients on long-term therapy, slower tapering (10% per month or slower) may be necessary 2
- Never discontinue pregabalin abruptly in patients who have been taking it regularly, even at prescribed doses 3
Supportive Care
- Symptomatic management of specific withdrawal symptoms
- Adequate hydration
- Close monitoring for seizures or severe psychiatric symptoms
Clinical Pitfalls to Avoid
- Misattribution of symptoms: Withdrawal symptoms can be mistaken for worsening of the original condition being treated
- Inadequate tapering: Even patients on regular prescribed doses for as little as 2 months can experience withdrawal 3
- Failure to recognize withdrawal: Pregabalin withdrawal can occur even in patients without psychiatric disorders or history of substance abuse 3
- Underestimating severity: Severe cases can lead to seizures, confusion, and significant distress
Pregabalin withdrawal is a significant clinical concern that requires careful management through proper tapering and symptom monitoring, even in patients taking regular prescribed doses without a history of substance abuse.
