What is Pregabalin?
Pregabalin belongs to a group of medicines that are thought to control pain by working on brain chemicals which send signals to nerves. These chemical are called gamma-aminobutyric acid or GABA. Pregabalin is best known as an anti-epileptic medicine.
Pregabalin may be used alone, or in combination with other medicines, to treat nerve (neuropathic) pain or fibromyalgia.
Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.
What benefit can you expect from your treatment?
Pregabalin is used to reduce neuropathic (nerve) pain. This means it is especially good at reducing sensations such as hot, burning, throbbing, shooting, stabbing, sharp, cramping, aching, tingling, numbness, pins and needles pain and for pain that keeps you awake at night.
How is Pregabalin taken?
As the drugs to treat neuropathic pain can have unpleasant side effects your doctor will usually recommend that you start with a low dose of Pregabalin and slowly increase the dose to the lowest amount needed to control your pain.
Your doctor or pharmacist will tell you how many capsules you need to take each day. This may depend on your age, your condition and whether or not you are taking any other medicines.
Swallow the capsules whole with a full glass of water.
When should it be taken?
Pregabalin is usually taken in two divided doses, so morning and evening, it can sometimes also be as three diced doses, with a dose in the middle of the day.
It does not matter if you take this medicine before or after food.
Take your medicine at about the same time each day. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
What is the dosage?
Pregabalin comes in different strength capsules. The initial dose may be 25 to 75mg a day increasing every three to seven days. The lowest possible to control your pain will be used. The usual maintenance daily dose range is 150 mg per day to 600 mg per day given in two or three divided doses.
Can other medicines be taken with Pregabalin?
The absorption of Pregabalin is affected by certain indigestion/antacid mixtures.
Tell your doctor if you are taking any other medicines, including medicines that you buy at the chemist, supermarket or health food shop.
Your doctor or pharmacist can tell you what to do if you are taking any other medicines.
Pregabalin is sometimes used with other pain relieving medications.
How long is the treatment continued?
Treatment with Pregabalin is continued indefinitely as long as it is effective and as long as no serious side effects occur.
If you stop Pregabalin treatment for more than a few weeks there is a risk that your condition may worsen. Continue with your treatment unless advised by your doctor or unless side effects develop.
If you have an illness that makes you unwell enough to change plans for the day (e.g. gastroenteritis or fever), it is reasonable to miss the weekly dose until you have recovered.
Are there any side effects?
You might experience side effects with your treatment. Tell your doctor if you are concerned about possible side effects.
A reduction in dose may minimise side effects so that you can continue to take the treatment. Your doctor will advise on any dose changes that are necessary.
