1. What Alzain is and what it is used for

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

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

Generalised Anxiety Disorder: Alzain 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 Alzain

Do not take Alzain

  • 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 Alzain.

  • Some patients taking Alzain 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.
  • Alzain has been associated with dizziness and somnolence, 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.
  • Alzain 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 Alzain; 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 Alzain. If while taking Alzain 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 Alzain have had thoughts of harming or killing themselves. If at any time you have these thoughts, immediately contact your doctor.
  • When Alzain 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 Alzain or shortly after stopping Alzain. If you experience a convulsion, contact your doctor immediately.
  • There have been reports of reduction in brain function (encephalopathy) in some patients taking Alzain 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.

Other medicines and Alzain

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Alzain and certain other medicines may influence each other (interaction). When taken with certain other medicines, Alzain may potentiate the side effects seen with these medicines, including respiratory failure and coma. The degree of dizziness, sleepiness and decreased concentration may be increased if Alzain is taken together with medicinal products containing:

Oxycodone – (used as a pain killer)

Lorazepam – (used for treating anxiety)

Alcohol

Alzain may be taken with oral contraceptives.

Alzain with food, drink and alcohol

Alzain capsules may be taken with or without food.

It is advised not to drink alcohol while taking Alzain.

Pregnancy and breast-feeding

Alzain should not be taken during pregnancy or when breast-feeding, unless you are told otherwise by your doctor. Effective contraception must be used by women of child bearing potential. If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Driving and using machines

Alzain may produce dizziness, sleepiness and decreased concentration. You should not drive, operate complex machinery or engage in other potentially hazardous activities until you know whether this medicine affects your ability to perform these activities.

3. How to take Alzain

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

Your doctor will determine what dose is appropriate for you.

Alzain is for oral use only.

Peripheral and central neuropathic pain, epilepsy or Generalised Anxiety Disorder:

  • Take the number of capsules as instructed by your doctor.
  • The dose, which has been adjusted for you and your condition, will generally be between 150 mg and 600 mg each day.
  • Your doctor will tell you to take Alzain either twice or three times a day. For twice a day take Alzain once in the morning and once in the evening, at about the same time each day. For three times a day take Alzain once in the morning, once in the afternoon and once in the evening, at about the same time each day.

If you have the impression that the effect of Alzain is too strong or too weak, talk to your doctor or pharmacist.

If you are an elderly patient (over 65 years of age), you should take Alzain normally except if you have problems with your kidneys.

Your doctor may prescribe a different dosing schedule and/or dose if you have problems with your kidneys.

Swallow the capsule whole with water.

Continue taking Alzain until your doctor tells you to stop.

If you take more Alzain than you should

Call your doctor or go to the nearest hospital emergency unit immediately. Take your box of Alzain capsules with you. You may feel sleepy, confused, agitated, or restless as a result of taking more Alzain than you should. Fits have also been reported.

If you forget to take Alzain

It is important to take your Alzain capsules regularly at the same time each day. If you forget to take a dose, take it as soon as you remember unless it is time for your next dose. 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 Alzain

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

These include, trouble sleeping, headache, nausea, feeling anxious, diarrhoea, flu like symptoms, convulsions, nervousness, depression, pain, sweating, and dizziness.
