1. What Pregabalin Ascend is and what it is used for

Pregabalin Ascend belongs to a group of medicines used to treat epilepsy, neuropathic pain and Generalised Anxiety Disorder (GAD) in adults.

Peripheral and central neuropathic pain: This medicine is used to treat long lasting pain caused by damage to the nerves. A variety of diseases can cause peripheral neuropathic pain, such as diabetes or shingles. Pain sensations may be described as hot, burning, throbbing, shooting, stabbing, sharp, cramping, aching, tingling, numbness, pins and needles. Peripheral and central neuropathic pain may also be associated with mood changes, sleep disturbance, fatigue (tiredness), and can have an impact on physical and social functioning and overall quality of life.

Epilepsy:

This medicine is used to treat a certain form of epilepsy (partial seizures with or without secondary generalisation) in adults. Your doctor will prescribe Pregabalin for you to help treat your epilepsy when your current treatment is not controlling your condition. You should take Pregabalin in addition to your current treatment. Pregabalin is not intended to be used alone, but should always be used in combination with other anti-epileptic treatment.

Generalised Anxiety Disorder:

This medicine is used to treat Generalised Anxiety Disorder (GAD). The symptoms of GAD are prolonged excessive anxiety and worry that are difficult to control. GAD can also cause restlessness or feeling keyed up or on edge, being easily fatigued (tired), having difficulty concentrating or mind going blank, feeling irritable, having muscle tension or sleep disturbance. This is different to the stresses and strains of everyday life.

2. What you need to know before you take Pregabalin Ascend

Do not take Pregabalin Ascend

  • if you are allergic to pregabalin or any of the other ingredients of this medicine (listed in

    section 6).

Warnings and Precautions

Talk to your doctor or pharmacist before taking Pregabalin.

  • Some patients taking Pregabalin have reported symptoms suggesting an allergic reaction.

    These symptoms include swelling of the face, lips, tongue, and throat, as well as diffuse skin rash. Should you experience any of these reactions, you should contact your physician immediately.

  • Pregabalin has been associated with dizziness and sleepiness, which could increase the

    occurrence of accidental injury (fall) in elderly patients. Therefore, you should be careful until you are used to any effect the medicine might have.

  • Pregabalin may cause blurring or loss of vision, or other changes in eyesight, many of which

    are temporary. You should immediately tell your doctor if you experience any changes in your vision.

  • Some patients with diabetes who gain weight while taking pregabalin may need an alteration

    in their diabetic medicines.

  • Certain side effects may be more common, such as sleepiness, because patients with spinal

    cord injury may be taking other medicines to treat, for example, pain or spasticity, that have similar side effects to Pregabalin and the severity of these effects may be increased when taken together.

  • There have been reports of heart failure in some patients when taking Pregabalin; these

    patients were mostly elderly with cardiovascular conditions. Before taking this medicine you should tell your doctor if you have a history of heart disease.

  • There have been reports of kidney failure in some patients when taking Pregabalin. If while

    taking Pregabalin you notice decreased urination, you should tell your doctor as stopping the medicine may improve this.

  • A small number of people being treated with anti-epileptics such as Pregabalin have had

    thoughts of harming or killing themselves. If at any time you have these thoughts, immediately contact your doctor.

  • When Pregabalin is taken with other medicines that may cause constipation (such as some

    types of pain medicines) it is possible that gastrointestinal problems may occur (e.g. constipation, blocked or paralysed bowel). Tell your doctor if you experience constipation, especially if you are prone to this problem.

  • Before taking this medicine you should tell your doctor if you have a history of alcoholism or

    any drug abuse or dependence. Do not take more medicine than prescribed.

  • There have been reports of convulsions when taking Pregabalin or shortly after stopping

    Pregabalin. If you experience a convulsion, contact your doctor immediately.

  • There have been reports of reduction in brain function (encephalopathy) in some patients

    taking Pregabalin when they have other conditions. Tell your doctor if you have a history of any serious medical conditions, including liver or kidney disease.

Children and adolescents

The safety and efficacy in children and adolescents (under 18 years of age) has not been established and therefore, pregabalin should not be used in this age group.

Pregabalin Ascend and certain other medicines may influence each other (interaction).

  • Alcohol

Pregabalin may be taken with oral contraceptives.

Use in elderly patients

Use in patients with kidney problems

In that case, just carry on with the next dose as normal. Do not take a double dose to make up for a forgotten dose.

If you stop taking Pregabalin Ascend

Do not stop taking Pregabalin unless your doctor tells you to. If your treatment is stopped it should be done gradually over a minimum of 1 week.
