About pregabalin

Type of medicine

An anti-epileptic medicine

Used for

Epilepsy; neuropathic pain; general anxiety disorder

Also called

Lyrica®; Alzain®, Axalid®

Available as

Capsules, tablets and oral liquid medicine

Pregabalin belongs to a group of medicines known as anti-epileptic medicines, although it is prescribed for the treatment of several different conditions. You may have been prescribed pregabalin for the treatment of partial seizures, which are a type of epilepsy. A seizure is a short episode of symptoms which is caused by a burst of abnormal electrical activity in the brain. With a partial seizure, the burst of electrical activity stays in one part of the brain. Therefore, you tend to have localised or 'focal' symptoms. Pregabalin works by reducing the abnormal electrical activity in the brain. It is taken alongside other medicines for epilepsy.

Pregabalin is also prescribed to treat certain types of long-lasting pain caused by damage to nerves. This type of pain, called neuropathic pain, can be caused by a number of different conditions, including diabetes (where it is called diabetic neuropathy) and shingles (where it is called postherpetic neuralgia).

Pregabalin can also be helpful in treating the symptoms of generalised anxiety disorder (GAD), particularly if other medicines which are more often prescribed for people with this condition are not suitable. GAD is a long-term condition where anxiety is a major symptom.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking pregabalin it is important that your doctor knows:

  • If you are under 18 years of age.

  • If you are pregnant, trying for a baby or breastfeeding.

  • If you have any problems with the way your kidneys work.

  • If you have any problems with your heart.

  • If you have ever had drug or alcohol dependence problems.

  • If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.

  • If you have ever had an allergic reaction to a medicine.

  • Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about pregabalin and will provide you with a full list of the side-effects which you may experience from taking it.

  • Take pregabalin exactly as your doctor tells you to. The dose varies from one person to another so it is important that you follow your doctor's instructions carefully. There are several strengths of pregabalin capsules available, so it is always worth checking the strength of the capsules each time you get a new prescription to make sure they are what you are expecting.

  • You will be advised to take a low dose when you first start taking pregabalin, and then to increase the dose over the first few weeks. This is to allow your body to get used to the new medicine. Most people take two or three doses a day once they are on a regular maintenance dose. Your doctor will explain all this to you, and the dosing directions will be printed on the label of the pack. If you are still unsure about how to take your doses, seek medical advice from a pharmacist.

  • You can take pregabalin before or after food. Swallow the capsules with a drink of water. If you have been supplied with oral liquid medicine, see the instructions below for using the oral dosing syringe.

  • Once you are taking a regular amount of pregabalin, try to take your doses at the same times each day. This will help you avoid missing doses.

  • If you do forget to take a dose, take one as soon as you remember. Try to take the correct number of doses each day, but do not take two doses at the same time.

Instructions for using the dosing syringe with Lyrica® Oral Solution

  1. Remove the bottle cap, and push the syringe adaptor into the top of the open bottle.

  2. Insert the syringe into the adapter.

  3. Turn the bottle (with the syringe connected to it) upside down.

  4. Gently pull out the plunger of the syringe so that the solution fills the syringe to the mark which corresponds to your dose. Make sure any air bubbles are removed.

  5. Turn the bottle the correct way up again, and remove the syringe from the bottle.

  6. Put the tip of the syringe into your mouth, and gently push the plunger so that the liquid is released into your mouth.

  7. Replace the bottle cap (leaving the adapter in the bottle). Wash the syringe with water after each use.

  • Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress.

  • A small number of people have developed mood changes or suicidal thoughts whilst being treated with anti-epileptics. If this happens to you, you must tell your doctor about it straightaway.

  • You must avoid getting pregnant while you are taking pregabalin, so make sure you have discussed with your doctor which types of contraception are suitable for you. If you want to have a family, make sure that you discuss this with your doctor before you become pregnant. This is so that you can be given advice about your treatment from a specialist. If you become pregnant while you are taking pregabalin, you must tell your doctor straightaway.

  • When you first start a new treatment for epilepsy there may be a change in the number or type of seizures you experience. Your doctor will advise you about this.

  • People with epilepsy must stop driving. Your doctor will advise you about when it may be possible for you to start driving again. This will usually be after a year free of seizures.

  • You must take pregabalin regularly every day. Stopping treatment suddenly can cause problems which will make you feel unwell. If it becomes necessary for the treatment to stop, your doctor will ask you to reduce your dose over a period of at least a week.

Frequently asked questions

Can I take pregabalin if I am currently taking other medications?

You should always tell your doctor about all medicines you are taking, including those bought without a prescription, as well as herbal and complementary medicines.

How long will it take for pregabalin to start working?

When you first start pregabalin, you will be advised to take a low dose, which will then be gradually increased over the first few weeks. This allows your body to adjust to the medicine.

What should I do if I forget a dose of pregabalin?

Pregabalin can cause side-effects such as feeling dizzy, sleepy, or having blurred or double vision. If you experience these symptoms, you should not drive or use tools or machinery.
