What is Neurexal (Pregabalin)?
Neurexal is a brand name medication containing the active ingredient pregabalin. Pregabalin is a prescription-only drug that works within the central nervous system to calm overactive nerves. It is indicated for the treatment of several conditions in adults, including:
- Peripheral and central neuropathic pain, which is pain caused by damaged nerves resulting from conditions like diabetes, shingles, or spinal cord injury.
- Epilepsy, as an adjunctive therapy for partial onset seizures.
- Generalized Anxiety Disorder (GAD).
- Fibromyalgia, a condition characterized by widespread pain and stiffness.
How to Take Neurexal: Administration and Guidelines
Proper administration is key to Neurexal's effectiveness and your safety. Always follow your doctor's specific instructions, as the administration can vary based on your condition, weight, and kidney function.
General administration guidelines
- Dosage schedule: Your doctor will likely determine a specific schedule for taking Neurexal to minimize side effects and maintain a steady level of the medicine in your body.
- With or without food: Immediate-release Neurexal (capsules and oral solution) can be taken with or without food. However, extended-release tablets should be taken once daily after an evening meal.
- Swallowing capsules: Swallow the capsules whole with a drink of water. Do not crush, chew, or split them.
- Measuring liquid: If you are using the oral solution, use the provided measuring spoon or syringe. A household teaspoon will not measure accurately.
- Avoid alcohol: Do not drink alcohol while taking Neurexal. Combining them can increase side effects like sleepiness and dizziness and increase the risk of respiratory failure.
What to do for a missed dose
If you forget a dose, how you proceed depends on your dosing schedule:
- If you take Neurexal regularly throughout the day: Take the missed dose as soon as you remember. However, if it is almost time for your next dose, skip the missed one entirely. Do not take a double dose to make up for the missed one.
- If you take an extended-release tablet: Follow specific instructions provided by your doctor or in the medication guide, which may involve taking it with a meal later in the day.
Key Precautions and Warnings
Before and during treatment with Neurexal, certain precautions must be taken to ensure your safety and well-being. Always keep your doctor informed of any changes in your health or other medications you are taking.
Monitoring for mental health changes
A small number of patients taking anticonvulsants like pregabalin have experienced suicidal thoughts or behavior. It is crucial for patients, families, and caregivers to monitor for unusual changes in mood or behavior. Report any signs of panic attacks, agitation, depression, or suicidal ideation to your doctor immediately.
Risk of swelling and weight gain
Some patients may experience swelling of the hands, feet, and ankles (peripheral edema), as well as weight gain. This is particularly concerning for elderly patients or those with pre-existing heart conditions, like congestive heart failure, as Neurexal can worsen their condition.
Other important precautions
- Drowsiness and dizziness: Neurexal can cause tiredness, dizziness, and blurred vision, especially when you first start taking it. Do not drive or operate heavy machinery until you know how this medication affects you.
- Allergic reactions: Serious allergic reactions, such as angioedema (swelling of the face, lips, tongue, or throat), have been reported. Seek immediate medical help if you experience signs of a serious allergic reaction.
- Kidney problems: If you have kidney problems, your doctor will adjust your treatment plan accordingly.
Neurexal vs. Other Pregabalin Formulations
While Neurexal itself is a specific brand, its active ingredient, pregabalin, is available in various formulations. Below is a comparison of standard release (like Neurexal capsules) and extended-release tablets.
| Feature | Neurexal (Standard/Immediate-Release) Capsules | Extended-Release Tablets |
|---|---|---|
| Administration Frequency | Typically taken multiple times a day | Taken once a day |
| Food Interaction | Can be taken with or without food | Should be taken after an evening meal |

| Suitability for Renal Impairment | Treatment can be adjusted for renal impairment | Generally not recommended for severe renal impairment or dialysis patients |
Safely Discontinuing Neurexal
It is vital that you never stop taking Neurexal abruptly, even if you feel well. Suddenly discontinuing the medication can trigger withdrawal symptoms, including:
- Insomnia
- Headaches
- Nausea
- Anxiety
- Seizures (especially in epilepsy patients)
Your doctor will provide a tapering schedule to reduce your intake gradually, typically over at least a week, to prevent these withdrawal effects. Always follow this schedule carefully and consult your doctor if you experience any issues.
Conclusion
Taking Neurexal requires careful adherence to your doctor's instructions to ensure its effectiveness and your safety. By understanding the correct administration schedule, potential side effects, and the risks associated with sudden discontinuation, you can manage your treatment responsibly. Communication with your healthcare provider is the most critical step throughout your therapy with Neurexal.
