What is Lyrica CR?

Lyrica CR is an anti-epileptic drug, also called an anticonvulsant. Pregabalin works by slowing down nerve impulses in the brain and affects chemicals that send pain signals across the nervous system.

Lyrica CR is a prescription medicine used to treat pain caused by damaged nerves in people with diabetes (diabetic neuropathy). Lyrica CR is also used to treat pain caused by damaged nerves (neuropathic pain) that follows healing of shingles (herpes zoster). This condition is called post-herpetic neuralgia.

.

It is not known if Lyrica CR is effective when used for the treatment of fibromyalgia, or when taken with other seizure medicines for adults with partial onset seizures.

Lyrica CR is supplied as extended-release tablets in the following strengths: 82.5 mg, 165 mg, and 330 mg.

How should I take Lyrica CR?

Take Lyrica CR exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

Take the medicine at the same time each day, with or without food.

Swallow an extended-release tablet whole and do not crush, chew, or break it.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

Call your doctor if your symptoms do not improve, or if they get worse.

Do not stop using Lyrica CR suddenly, even if you feel fine. Stopping suddenly may cause unpleasant withdrawal symptoms. Follow your doctor's instructions about tapering your dose for at least 1 week before stopping completely.

Store at room temperature away from moisture, heat, and light.

Warnings

Lyrica CR can cause a severe allergic reaction. Stop taking Lyrica CR 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 Lyrica CR. 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 Lyrica CR.

Do not stop using Lyrica CR suddenly, even if you feel fine. Stopping suddenly may cause withdrawal symptoms.

Before taking this medicine

You should not use Lyrica CR if you are allergic to pregabalin.

To make sure Lyrica CR is safe for you, tell your doctor if you have::

  • lung disease, such as chronic obstructive pulmonary disease (COPD);
  • a mood disorder, depression, or suicidal thoughts;
  • heart problems (especially congestive heart failure);
  • a bleeding disorder, or 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).

Do not give this medicine to a child without medical advice.

  • Lyrica CR is not approved for use by anyone younger than 18 years old to treat nerve pain caused by diabetes or shingles (herpes zoster).

Some people have thoughts about suicide while taking Lyrica CR. Your doctor will need to check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.

It is not known if pregabalin will harm your unborn baby. You and your healthcare provider will have to decide if you should take Lyrica CR while you are pregnant.

If you are pregnant, your name may be listed on a pregnancy registry to track the effects of pregabalin on the baby.

Lyrica CR 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.

You should not breastfeed while using Lyrica CR.

Lyrica vs Gabapentin: What's the difference?
Both Lyrica (pregabalin) and gabapentin (Neurontin) are both anticonvulsants and gabapentinoids used to treat nerve pain and seizures, but they differ significantly in potency, absorption speed, and regulatory status. Lyrica is generally more potent, faster-acting (peaks in approximately 1 hour), and is a Schedule V controlled substance, whereas gabapentin peaks in 3 to 4 hours, is less regulated in most states, and is usually cheaper.

How long does Lyrica (pregabalin) stay in your system?
Lyrica (pregabalin) will stay in your blood (plasma) for about 32 hours, but its clinical effect may wear off before this time. However, clinical studies have shown pregabalin to be detectable in urine drug tests for up to 5 to 6 days. Continue reading
Can you stop Lyrica (pregabalin) cold turkey?
