Lyrica contains pregabalin, used mainly for nerve pain — diabetic neuropathy, shingles pain, sciatica and fibromyalgia — and also for epilepsy and generalised anxiety disorder. It works on nerve signalling rather than as an ordinary painkiller, takes time to build up, and must not be stopped abruptly.
What is Lyrica?
Lyrica contains pregabalin, dispensed in South Africa in 25 mg, 75 mg and 150 mg strengths and classified Schedule 5.
Pregabalin belongs to a group sometimes called gabapentinoids. Despite the chemical resemblance in its name, it does not act on GABA receptors. It binds to a subunit of calcium channels on overactive nerve endings, reducing the release of the signalling chemicals that carry pain messages and drive excessive nerve firing.
That mechanism explains its range. Nerve pain, epilepsy and anxiety all involve nerves firing more than they should, in different parts of the system — so one medicine that calms excessive nerve signalling has a role in all three.
It is important to understand that pregabalin is not an ordinary painkiller. It does nothing for a headache or a sprained ankle. It targets pain generated by damaged or oversensitive nerves, which is a different kind of pain and one that responds poorly to paracetamol and anti-inflammatories.
The same ingredient is dispensed in South Africa as Nurika and other generics.
What is Lyrica commonly used for?
Pregabalin is prescribed for:
- Neuropathic pain — the main use. This includes diabetic nerve pain, pain after shingles, sciatica, nerve pain after injury or surgery, and pain from nerve compression.
- Fibromyalgia, where widespread pain and sleep disturbance are features.
- Epilepsy, as add-on treatment for partial seizures.
- Generalised anxiety disorder, in some countries and circumstances.
Nerve pain feels different, which is why people often struggle to describe it: burning, shooting, electric-shock sensations, pins and needles, numbness, or pain from something that should not hurt at all, such as bedsheets on the skin. If that matches your experience, pregabalin is aimed at the right thing.
It builds up gradually. Prescribers usually start low and increase over days or weeks, both to limit side effects and to find the amount that works. Benefit often takes one to two weeks to become clear, sometimes longer. Judging it after a few days is judging it too early.
How Lyrica fits into this medicine category
Within mental health and neurological medicines, Lyrica is an antiepileptic used across pain, seizures and anxiety:
| Group | Examples | Common uses |
|---|---|---|
| Gabapentinoids | Pregabalin (Lyrica, Nurika), gabapentin | Nerve pain, epilepsy, anxiety |
| Tricyclics | Amitriptyline (Trepiline) | Nerve pain, migraine prevention, sleep |
| SSRIs and newer antidepressants | Various | Depression, anxiety |
| Other antiepileptics | Carbamazepine, valproate, lamotrigine | Epilepsy, some nerve pain, mood |
| Benzodiazepines | Diazepam, alprazolam | Short-term anxiety |
Pregabalin and amitriptyline are the two mainstays of nerve pain treatment in ordinary practice, from entirely different classes. Prescribers often try one and then the other, and sometimes combine them. Being switched is normal. See the mental health, nerve and neurological medicines hub.
What to check before using Lyrica
Do not drive until you know how it affects you. Dizziness and drowsiness are the most common effects, particularly while the dose is being increased.
Tell your prescriber or pharmacist if:
- You have kidney disease. Pregabalin is cleared by the kidneys and the amount usually needs reducing — this is one of the more important adjustments with this medicine.
- You have breathing problems, including COPD or sleep apnoea. Regulators including SAHPRA have issued specific warnings about serious breathing difficulty with gabapentinoids, particularly in older people, those with reduced lung function, and when combined with opioids.
- You take opioids such as tramadol or codeine. The combination increases sedation and the risk of suppressed breathing.
- You have a history of substance dependence. Pregabalin has recognised misuse potential and is a Schedule 5 medicine here for that reason.
- You have heart failure, where fluid retention matters.
- You are pregnant, planning pregnancy or breastfeeding.
- You have depression or thoughts of self-harm.
- You take other sedating medicines, or drink alcohol.
Follow the dispensing label — this page does not set doses, and the amount is normally increased in steps.
Possible cautions and when to ask a pharmacist or doctor
Do not stop abruptly. Stopping suddenly after regular use can cause withdrawal — anxiety, difficulty sleeping, nausea, headache, sweating, and in people taking it for epilepsy, an increased risk of seizures. It is tapered over at least a week, usually longer.
Breathing problems are a specific warning. Seek urgent medical attention for slow or shallow breathing, unusual sleepiness, or difficulty waking — particularly if you also take an opioid or have lung disease.
Expect dizziness and drowsiness, especially early on and after each increase. These often ease.
Weight gain and fluid retention are common with longer use. Report significant ankle swelling.
Blurred vision occurs in some people and should be reported.
Misuse and dependence. Pregabalin is misused for its sedative effects, and dependence can develop. Needing more than prescribed, or finding it hard to stop, is worth discussing with a doctor — this is recognised and treatable.
Mood changes. Report worsening depression or thoughts of self-harm promptly. In South Africa the SADAG helpline operates nationally, and any emergency department can help.
Seek urgent attention for breathing difficulty, swelling of the face or throat, a severe rash, or thoughts of harming yourself.

Frequently asked questions
What is Lyrica used for? Mainly nerve pain — diabetic neuropathy, shingles pain, sciatica, fibromyalgia — and also epilepsy and, in some settings, generalised anxiety disorder.
Is it a painkiller? Not an ordinary one. It works on nerve signalling and helps pain generated by damaged or oversensitive nerves. It does nothing for a headache or a sprain.
How long before it works? Often one to two weeks, sometimes longer, and the dose is usually increased gradually. Judging it after a few days is too early.
Is Lyrica the same as Nurika? Both contain pregabalin. Lyrica is the originator brand; Nurika is a South African generic.
Can I stop taking it when the pain settles? Not abruptly. It is tapered to avoid withdrawal, and stopping suddenly can increase seizure risk in people with epilepsy. Ask your prescriber.
Is pregabalin addictive? It has recognised misuse potential and is Schedule 5 in South Africa. Taken as prescribed it has a clear role; discuss any escalating need with your doctor.
