What is pregabalin?
Pregabalin is used for the relief of nerve pain (also called neuropathy). Nerve pain occurs when damage or changes to your nerves through injury or disease such as diabetes or shingles, causes them to misfire and send pain signals to the brain. Read more about nerve pain.
Pregabalin is also used to treat epilepsy, by preventing some types of seizures, and can also be helpful in treating the symptoms of generalised anxiety disorder, if other medicines are not suitable.
In New Zealand, pregabalin is available as capsules (25 mg, 75 mg, 150 mg and 300 mg).
- The usual dose of pregabalin is 150 mg two times a day.
- Your doctor will start you on a low dose of 75 mg two times a day and increase the dose after a few days. This allows your body to get used to the medicine and reduces the chances of side effects.
- Always take your pregabalin exactly as your doctor has told you. The pharmacy label on your medicine will tell you how much pregabalin to take, how often to take it, and any special instructions.

How to take pregabalin
- Take pregabalin at the same times each day. You need to take pregabalin regularly and not just when your nerve pain gets bad.
- Swallow the capsules with a glass of water.
- You can take pregabalin with or without food. Try taking pregabalin with food if it makes you feel sick (nausea).
- Limit or avoid alcohol while taking pregabalin. Taking pregabalin and alcohol can make your more sleepy, drowsy or dizzy.
- There are many strengths of pregabalin capsules available. Check the strength of the capsules each time you get a new prescription to make sure they are what you are expecting.
- If you forget to take your dose, take it as soon as you remember that day. But, if it is nearly time for your next dose, just take the next dose at the right time. Do not take double the amount.
- If you are taking pregabalin for pain, it does not relieve pain immediately – it may take a few days before you start noticing a reduction in pain.
- If you think pregabalin is not working for you, do not stop taking it suddenly; speak to your doctor or nurse before stopping. It is usually best to stop taking pregabalin slowly to avoid side effects.
Precautions – before starting pregabalin
- Do you have kidney problems?
- Do you have problems with your heart?
- Do you have diabetes?
- Are you pregnant or breastfeeding?
- Are you taking any other medicines? This includes any medicines you buy without a prescription, such as herbal and complementary medicines.
If so, it’s important that you tell your doctor or pharmacist before you start pregabalin. Sometimes a medicine isn’t suitable for a person with certain conditions, or it can only be used with extra care.
Possible side effects
Like all medicines, pregabalin can cause side effects, although not everyone gets them. Often side effects improve as your body gets used to the new medicine.
Problems with balance and drowsiness
This is quite common when you start taking pregabalin. Up to 1 in 3 people experience dizziness or drowsiness.
- Be careful when driving or using tools until you know how this medicine affects you.
- Also be careful when getting up from either lying down or sitting – the loss of balance and dizziness can put you at risk of falls and injuries, especially if you are elderly.
- Avoid drinking alcohol while you are taking pregabalin. This can make dizziness and drowsiness worse.
Tell your doctor if these side effects are troublesome – you may need a lower dose.
Risk of dependence
Pregabalin can cause feelings of excitement and exaggerated happiness (often described as a high or euphoria). Therefore, it has the potential to become habit forming. The risk of dependence may be higher if you have a history of misuse of alcohol and recreational drugs. To avoid pregabalin dependence, do not take it in higher doses, more frequent doses or for longer than you were prescribed by a doctor. Let your doctor know if you have any history of drug abuse or start to feel any sense of high or desire for your next dose.
