What is pregabalin?
Pregabalin is used to relieve 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 your 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 2 times a day, but some people may need a higher dose.
- 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
- Timing: You can take pregabalin with or without food. Try taking pregabalin with food if it makes you feel sick (nausea). 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 whole, with a glass of water: Do not open the capsules. If you have problems swallowing pregabalin capsules, talk to your doctor or pharmacist. Read more about tips for swallowing tablets and capsules.
- Limit or avoid alcohol while taking pregabalin: Taking pregabalin and alcohol can make you more sleepy, drowsy or dizzy and increase your risk of falls.
- Missed dose: If you forget to take your dose, take it as soon as you remember that day. But if it is nearly time (within 4 hours) for your next dose, just take the next dose at the right time. Do not take double the dose.
- Pain relief is not immediate: If you are taking pregabalin for pain, it does not relieve pain immediately. It may take a few days before you feel less pain.
- Keep taking pregabalin regularly: If you think pregabalin is not working for you, do not stop taking it suddenly. Stopping treatment suddenly can cause side effects. Speak to your doctor or nurse before stopping. It is usually best to stop pregabalin slowly.
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 and medicines for pain relief.
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.
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 causing you problems. 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). For some people, it can become habit forming. The risk of dependence may be higher if you have a history of misuse of alcohol and recreational drugs and if you are taking pregabalin in combination with certain other medicines.
To avoid pregabalin dependence, do not take 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 or if you start taking any new medicines for pain relief.
Always keep pregabalin in a safe place away from children, and do not share this medicine with others.
