What is pregabalin?
Pregabalin is an anti-epileptic drug, also called an anticonvulsant. It works by slowing down impulses in the brain that cause seizures. Pregabalin also affects chemicals in the brain that send pain signals across the nervous system.
Pregabalin is used to control seizures and to treat fibromyalgia. It is also used to treat pain caused by nerve damage in people with diabetes (diabetic neuropathy), herpes zoster (post-herpetic neuralgia), or spinal cord injury.
Pregabalin may also be used for purposes not listed in this medication guide.
Pregabalin can cause a severe allergic reaction. Stop taking this medicine and seek emergency medical help if you have hives or blisters on your skin, trouble breathing, or swelling in your face, mouth, or throat.
Some people have thoughts about suicide while taking pregabalin. Stay alert to changes in your mood or symptoms. Report any new or worsening symptoms to your doctor.
If you have diabetes or heart problems, call your doctor if you have weight gain or swelling in your hands or feet while taking pregabalin.
Do not stop using pregabalin suddenly, even if you feel fine. Stopping suddenly may cause withdrawal symptoms.
Before taking this medicine
You should not use pregabalin if you are allergic to it.
To make sure pregabalin is safe for you, tell your doctor if you have ever had:
heart problems (especially congestive heart failure);
low levels of platelets in your blood;
kidney disease (or if you are on dialysis);
diabetes (unless you are taking pregabalin to treat diabetic neuropathy);
drug or alcohol addiction; or
a severe allergic reaction (angioedema).
Some people have thoughts about suicide while taking pregabalin. Your doctor will need to check your progress at regular visits while you are using topiramate. Your family or other caregivers should also be alert to changes in your mood or symptoms.
Follow your doctor's instructions about taking seizure medication if you are pregnant. Seizure control is very important during pregnancy, and having a seizure could harm both mother and baby. Do not start or stop taking this medicine without your doctor's advice, and tell your doctor right away if you become pregnant.
If you are pregnant, your name may be listed on a pregnancy registry. This is to track the outcome of the pregnancy and to evaluate any effects of pregabalin on the baby.
This medication can decrease sperm count and may affect fertility in men (your ability to have children). In animal studies, pregabalin also caused birth defects in the offspring of males treated with this medicine. However, it is not known whether these effects would occur in humans. Ask your doctor about your risk.
It is not known whether pregabalin passes into breast milk or if it could affect the nursing baby. Tell your doctor if you are breast-feeding.
