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

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

It contains the pregabalin which belongs to a class of medicines called Gabapentinoids.

Peripheral and central neuropathic pain:

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

Do not take Pregabalin Relonchem

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, pharmacist or nurse before taking Pregabalin Relonchem.

  • Some patients taking Pregabalin Relonchem 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 Relonchem 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.
  • Pregabalin Relonchem 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 Relonchem; 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 Relonchem. If while taking Pregabalin Relonchem 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 Pregabalin Relonchem have had thoughts of harming or killing themselves or shown suicidal behaviour. If at any time you have these thoughts or shown such behaviour, immediately contact your doctor.
  • When Pregabalin Relonchem 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 are or have ever been addicted to opioids, alcohol, prescription medicines, or illegal drugs, or if you have ever had a history of struggling to control your alcohol or drug intake.

  • There have been reports of convulsions when taking Pregabalin Relonchem or shortly after stopping Pregabalin Relonchem. If you experience a convulsion, contact your doctor immediately.
  • There have been reports of reduction in brain function

    (encephalopathy) in some patients taking Pregabalin Relonchem 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 years of age, your doctor may prescribe you a different dosing regimen. Contact your doctor if you experience trouble breathing or shallow breaths.
  • Serious skin rashes including Stevens-Johnson syndrome and toxic epidermal necrolysis have been reported in association with pregabalin. Stop using Pregabalin Relonchem and seek medical attention immediately if you notice any of the symptoms related to these serious skin reactions described in section 4.

    • If you have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating, when you have stopped taking alcohol or drugs.

Dependence

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

If you notice any of the following signs whilst taking Pregabalin Relonchem, 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 safety. Gabapentinoids should only be used by those they are prescribed for. Do not give your medicine to anyone else. Taking higher doses or more frequent doses of gabapentinoids, may increase the risk of addiction. Overuse and misuse can lead to overdose and/or death.

Children and adolescents

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

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Pregabalin Relonchem and certain other medicines may influence each other (interaction). When taken with certain other medicines, which have sedative effects (including

opioids), Pregabalin

Relonchem 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

Pregabalin Relonchem is

taken together with

medicinal products

containing:

  • Oxycodone - (used as a

    pain-killer)

  • Lorazepam - (used for treating anxiety)
  • Alcohol

Pregabalin Relonchem may be taken with oral contraceptives. Pregabalin Relonchem with food, drink and alcohol

Pregabalin Relonchem capsules may be taken with or without food. It is advised not to drink alcohol while taking Pregabalin.

Pregnancy and breast-feeding

If you are pregnant, or think you may be pregnant, you must tell your doctor straight away and discuss possible risks the medicine you are taking might pose to your unborn baby. If you are planning to become pregnant you should discuss your treatment with your doctor as early as possible before you become pregnant. You should not stop your treatment without discussing this with your doctor.

Pregnancy

Pregabalin Relonchem 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. There has been limited research specifically looking at the use of pregabalin in pregnant women. A recent study suggested that women who took pregabalin while they were pregnant might have a slightly higher chance of having a baby born with physical birth abnormalities.

More research is needed to better understand and inform on the safety of use of pregabalin during pregnancy and whether it is associated with an increased risk of harm to the unborn child.

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. Driving and using machines

Pregabalin Relonchem 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.

Pregabalin Relonchem contains lactose monohydrate

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product. Pregabalin Relonchem contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per dosage unit, that is to say essentially 'sodium-free'.

3. How to take Pregabalin Relonchem

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure. Your doctor will determine what dose is appropriate for you. Pregabalin Relonchem is for oral use only.

Your doctor should have discussed with you how long the course of Pregabalin Relonchem capsules will last. They will arrange a plan for stopping treatment. This will outline how to gradually reduce the dose and stop taking the medicine. Your doctor will ensure that your plan for stopping treatment is tailored to you and can be adapted according to your needs and experience of any withdrawal symptoms.

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 Pregabalin Relonchem either twice or three times a day. For twice a day take Pregabalin Relonchem once in the morning and once in the evening, at about the same time each day. For three times a day take Pregabalin Relonchem 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 Pregabalin Relonchem 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 Pregabalin Relonchem 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 Pregabalin Relonchem until your doctor tells you to stop.

If you take more Pregabalin Relonchem than you should

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

unconsciousness, have also been reported.

If you forget to take Pregabalin Relonchem

It is important to take your Pregabalin Relonchem 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 Pregabalin Relonchem

Do not suddenly stop taking this medicine. If you want to stop taking this medicine, discuss this with your doctor first. They will tell you how to do this, usually by reducing the dose gradually so that any unpleasant withdrawal effects are kept to a minimum. This may occur over a period of weeks to months. Your doctor will ensure that your plan for stopping treatment is tailored to you and can be adapted according to your needs and experience of any withdrawal symptoms.

After stopping long and short-term Pregabalin Relonchem treatment, 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 Pregabalin Relonchem 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, pharmacist or nurse.
