Lifestyle & Tips
- Avoid alcohol and other CNS depressants (e.g., opioids, benzodiazepines) as they can increase side effects like dizziness and drowsiness.
- Do not drive or operate heavy machinery until you know how pregabalin affects you, as it can cause dizziness and somnolence.
- Do not stop taking pregabalin suddenly, especially if you have been taking it for a long time, as this can lead to withdrawal symptoms (e.g., insomnia, nausea, headache, anxiety, diarrhea, flu-like symptoms, nervousness, depression, pain, convulsions). Your doctor will guide you on how to slowly reduce the dose.

Precautions & Cautions
Before operating a vehicle or engaging in activities that require alertness and clear vision, wait until you understand how this medication affects you.
If you experience changes in your seizure patterns or if they worsen after starting this medication, consult your doctor promptly.
Do not abruptly discontinue this medication without first consulting your doctor, as this may increase your risk of side effects. If you need to stop taking this medication, your doctor will guide you on how to gradually taper off the dosage.
Avoid consuming alcohol while taking this medication.
Before using marijuana, cannabis products, or prescription and over-the-counter medications that may impair your physical or mental abilities, discuss the potential risks with your doctor.
A rare but potentially life-threatening reaction called angioedema has been associated with this medication. Symptoms may include swelling of the hands, face, lips, eyes, tongue, or throat, difficulty breathing, swallowing problems, or unusual hoarseness. Seek immediate medical attention if you experience any of these symptoms.
Severe respiratory problems have occurred in individuals taking this medication, particularly when combined with opioid pain medications or in those with pre-existing lung or breathing issues. The risk is higher in people over 65 years old, and in some cases, these breathing problems have been fatal. If you have concerns, consult your doctor.
If you are 65 years or older, use this medication with caution, as you may be more susceptible to side effects.
Men planning to father a child should discuss the potential risks with their doctor, as this medication has been shown to decrease fertility and cause sperm changes in male animals, and birth defects have occurred in the offspring of male animals treated with this medication. Although it is unknown whether these effects occur in humans, it is crucial to have this conversation.
If you are pregnant or plan to become pregnant, inform your doctor to discuss the benefits and risks of using this medication during pregnancy.
Overdose Information
Overdose Symptoms:
- Somnolence
- Confusion
- Agitation
- Restlessness
- Seizures (rare)
- Coma
What to Do:
In case of overdose, seek immediate medical attention or call a poison control center. In the US, call 1-800-222-1222. There is no specific antidote; treatment is supportive.
Drug Interactions
Major Interactions
- CNS depressants (e.g., opioids, benzodiazepines, alcohol): Increased risk of additive CNS depression, somnolence, respiratory depression, and sedation. Concomitant use should be approached with caution, and dose reduction of one or both agents may be necessary.
- Thiazolidinediones (e.g., pioglitazone, rosiglitazone): Increased risk of peripheral edema and weight gain when co-administered with pregabalin.
Moderate Interactions
- Angiotensin-converting enzyme (ACE) inhibitors: May increase risk of angioedema when co-administered with pregabalin.
Monitoring
Baseline Monitoring
Rationale: Pregabalin is primarily renally excreted; dose adjustment is necessary in renal impairment.
Timing: Prior to initiation of therapy.
Rationale: Pregabalin has abuse potential and is a Schedule V controlled substance.
Timing: Prior to initiation of therapy.
Rationale: Antiepileptic drugs, including pregabalin, may increase the risk of suicidal thoughts or behavior.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Regularly during titration and maintenance.
Target: Individualized based on patient response and tolerability.
Action Threshold: Lack of efficacy or intolerable side effects may warrant dose adjustment or discontinuation.
Frequency: Regularly, especially during dose titration.
Target: Absence or minimal severity of side effects.
Action Threshold: Significant or persistent adverse effects may require dose reduction or discontinuation.
Frequency: Periodically, especially in elderly patients or those with pre-existing renal impairment.
Target: Stable renal function.
Action Threshold: Decline in renal function necessitates dose adjustment.
Frequency: Regularly, especially in patients with a history of substance abuse.
Target: Not applicable.
Action Threshold: Signs of abuse or dependence require re-evaluation of therapy.
Symptom Monitoring
- Dizziness
- Somnolence
- Peripheral edema (swelling of hands, feet, ankles)
- Weight gain
- Blurred vision or other visual disturbances
- Suicidal thoughts or behavior (new or worsening depression, anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia, hypomania, mania)
- Signs of hypersensitivity reactions (e.g., angioedema, rash, hives)
- Muscle pain, tenderness, or weakness (rare, but could indicate rhabdomyolysis)
- Respiratory depression (especially with concomitant opioid use)
Special Patient Groups
Pregnancy
Pregabalin is Pregnancy Category C. There are no adequate and well-controlled studies in pregnant women. Animal studies have shown developmental toxicity (e.g., skeletal abnormalities, growth retardation) at doses higher than human therapeutic doses. Pregabalin should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Patients should be enrolled in the North American Antiepileptic Drug (NAAED) Pregnancy Registry.
Trimester-Specific Risks:
Lactation
Pregabalin is excreted into human milk. The relative infant dose is estimated to be low (around 7% of the maternal weight-adjusted dose). Monitor breastfed infants for sedation, poor feeding, and adequate weight gain. Use with caution, weighing the benefits of breastfeeding against potential infant exposure.
Pediatric Use
Safety and efficacy have not been established for all indications in pediatric patients. Approved for partial-onset seizures in children 1 month of age and older, with weight-based dosing. The 200mg capsule strength is generally not suitable for initial pediatric dosing. Increased risk of suicidal thoughts/behavior in children and adolescents.
Geriatric Use
Dose adjustment is often necessary in elderly patients due to age-related decline in renal function. Elderly patients may be more susceptible to adverse effects such as dizziness, somnolence, and peripheral edema, increasing the risk of falls. Start with lower doses and titrate slowly.
Clinical Information
Clinical Pearls
- Pregabalin is a Schedule V controlled substance due to potential for abuse and dependence. Prescribers should assess patients for a history of drug abuse and observe for signs of pregabalin misuse or abuse.
- Withdrawal symptoms can occur if pregabalin is discontinued abruptly, especially after long-term use. Taper the dose gradually over at least 1 week.
- Patients should be advised about the potential for dizziness, somnolence, and blurred vision, and cautioned against driving or operating machinery until they know how the drug affects them.
- Peripheral edema and weight gain are common side effects, particularly when co-administered with thiazolidinediones.
- Monitor for signs of angioedema, especially in patients taking ACE inhibitors concurrently.
- Counsel patients and caregivers about the risk of suicidal thoughts and behaviors and the need for immediate reporting of any new or worsening symptoms.
Alternative Therapies
- For Neuropathic Pain: Gabapentin, Duloxetine, Venlafaxine, Amitriptyline, Nortriptyline, Carbamazepine (for trigeminal neuralgia)
- For Fibromyalgia: Duloxetine, Milnacipran
- For Partial-Onset Seizures: Levetiracetam, Lamotrigine, Carbamazepine, Oxcarbazepine, Topiramate, Valproic acid
