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.
  • Serious skin rashes including Stevens-Johnson syndrome, toxic epidermal necrolysis have been reported in association with pregabalin. Stop using pregabalin and seek medical attention immediately if you notice any of the symptoms related to these serious skin reactions described in section 4.
  • 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.
  • Some patients being treated with anti-epileptics such as Alzain have had thoughts of harming or killing themselves or show suicidal behaviour. If at any time you have these thoughts or show such behaviour, 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, tell your doctor if you have ever abused or been dependent on alcohol, prescription medicines or illegal drugs; it may mean you have a greater risk of becoming dependent on Alzain.
  • 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.
  • There have been reports of breathing difficulties. If you have nervous system disorders, respiratory disorders, renal impairment, or you are older than 65, your doctor may prescribe you a different dosing regimen. Contact your doctor if you experience trouble breathing or shallow breaths.

Dependence

Some people may become dependent on Alzain (a need to keep taking the medicine). They may have withdrawal effects when they stop using Alzain (see section 3, “How to take Alzain” and “If you stop taking Alzain”). If you have concerns that you may become dependent on Alzain, it is important that you consult your doctor.

If you notice any of the following signs whilst taking Alzain, it could be a sign that you have become dependent:

  • You need to take the medicine for longer than advised by your prescriber
  • You feel you need to take more than the recommended dose
  • You are using the medicine for reasons other than prescribed
  • You have made repeated, unsuccessful attempts to quit or control the use of the medicine
  • When you stop taking the medicine you feel unwell, and you feel better once taking the medicine again

If you notice any of these, speak to your doctor to discuss the best treatment pathway for you, including when it is appropriate to stop and how to do this safely.

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 which have sedative effects (including opioids), Alzain may potentiate these effects and could lead to respiratory failure, coma and death. The degree of dizziness, sleepiness and decreased concentration may be increased if Alzain is taken together with medicines 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. Pregabalin use during the first 3 months of pregnancy may cause birth defects in the unborn child that require medical treatment. In a study reviewing data from women in Nordic countries who took pregabalin in the first 3 months of pregnancy, 6 babies in every 100 had such birth defects. This compares to 4 babies in every 100 born to women not treated with pregabalin in the study. Abnormalities of the face (orofacial clefts), the eyes, the nervous system (including the brain), kidneys and genitals have been reported.

Effective contraception must be used by women of childbearing 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.

Lyrica contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per hard capsule, that is to say essentially ‘sodium-free’.

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. Do not take more medicines than prescribed.

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 and unconsciousness (coma) 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 suddenly stop taking Alzain. If you want to stop taking Alzain, discuss this with your doctor first. They will tell you how to do this. If your treatment is stopped it should be done gradually over a minimum of 1 week.

After stopping short- or long term treatment with Alzain, you need to know that you may experience certain side effects, so called withdrawal effects. These effects include, trouble sleeping, headache, nausea, feeling anxious, diarrhoea, flu-like symptoms, convulsions, nervousness, depression, thoughts of harming or killing yourself, pain, sweating, and dizziness. These effects may occur more commonly or severely if you have been taking Alzain for a longer period of time. If you experience withdrawal effects, you should contact your doctor.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
