Patient leaflet - Ralnea XL 2 mg prolonged-release tablets

1. What Ropinirole Krka is and what it is used for

The active ingredient in Ropinirole Krka is ropinirole, which belongs to a group of medicines called dopamine agonists. Dopamine agonists affect the brain in a similar way to a natural substance called dopamine.

Ropinirole Krka prolonged-release tablets are used to treat Parkinson’s disease.

People with Parkinson’s disease have low levels of dopamine in some parts of their brains.

Ropinirole has effects similar to those of natural dopamine, so it helps to reduce the symptoms of

Parkinson’s disease.

2. What you need to know before you take Ropinirole Krka

Do NOT TAKE Ropinirole Krka:

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

    6)

  • if you have serious kidney disease
  • if you have liver disease

Tell your doctor if you think any of these may apply to you.

Warnings and precautions

Talk to your doctor or pharmacist before taking Ropinirole Krka:

  • if you are pregnant or think you may be pregnant
  • if you are breast feeding
  • if you are under 18 years old
  • if you have a serious heart complaint
  • if you have a serious mental health problem

    • if you have experienced any unusual urges and/or behaviours (see section 4)
    • if you have an intolerance to some sugars (such as lactose).

Tell your doctor if you think any of these may apply to you. Your doctor may decide that Ropinirole Krka is not suitable for you, or that you need extra check-ups while you are taking it.

Tell your doctor if you or your family/carer notices that you are developing urges or cravings to behave in ways that are unusual for you and you cannot resist the impulse, drive or temptation to carry out certain activities that could harm yourself or others. These are called impulse control disorders and can include behaviours such as addictive gambling, excessive eating or spending, an abnormally high sex drive or an increase in sexual thoughts or feelings, or aggressive behaviours. Your doctor may need to adjust or stop your dose.

Tell your doctor if you experience symptoms such as depression, apathy, anxiety, fatigue, sweating or pain after stopping or reducing your ropinirole treatment (called dopamine agonist withdrawal syndrome or DAWS). If the problems persist more than a few weeks, your doctor may need to adjust your treatment.

Tell your doctor if you or your family/carer notices that you are developing episodes of overactivity, elation or irritability (symptoms of mania). These may occur with or without the symptoms of impulse control disorders (see above). Your doctor may need to adjust or stop your dose.

While you are taking Ropinirole Krka

Tell your doctor if you or your family notices that you are developing any unusual behaviours (such as an unusual urge to gamble or increased sexual urges and/or behaviours) while you are taking Ropinirole Krka. Your doctor may need to adjust or stop your dose.

Smoking and Ropinirole Krka

Tell your doctor if you start smoking, or give up smoking, while you are taking Ropinirole Krka. Your doctor may need to adjust your dose.

Other medicines and Ropinirole Krka

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including any herbal medicines or other medicines you obtained without a prescription.

Remember to tell your doctor or pharmacist if you begin taking a new medicine while you are taking Ropinirole Krka.

Some medicines can affect the way Ropinirole Krka works, or make it more likely that you will have side effects. Ropinirole Krka can also affect the way some other medicines work.

These include:

  • the anti-depressant fluvoxamine;
  • medication for other mental health problems, for example sulpiride;
  • HRT (hormone replacement therapy);
  • metoclopramide, which is used to treat nausea and heartburn;
  • the antibiotics ciprofloxacin or enoxacin;
  • any other medicine for Parkinson’s disease.

Tell your doctor if you are taking or have recently taken any of these.

You will require additional blood tests if you are taking these medicines with Ropinirole Krka:

  • Vitamin K antagonists (used to reduce blood clotting) such as Warfarin (coumadin).

Ropinirole Krka with food and drink

You can take Ropinirole Krka with or without food.

Pregnancy and breast-feeding

Ropinirole Krka is not recommended if you are pregnant, unless your doctor advises that the benefit to you of taking Ropinirole Krka is greater than the risk to the unborn baby. Ropinirole Krka is not recommended if you are breast-feeding, as it can affect your milk production.

Tell your doctor immediately if you are pregnant, think you may be pregnant or if you are planning to become pregnant. Your doctor will also advise you if you are breast feeding or planning to do so. Your doctor may advise you to stop taking Ropinirole Krka.

Driving and using machines

Ropinirole Krka can make you feel drowsy. It can make people feel extremely sleepy, and it sometimes makes people fall asleep very suddenly without warning. Ropinirole can cause hallucinations (seeing, hearing or feeling things that are not there). If affected, do not drive or use machines.

If you could be affected: do not drive, do not operate machines and do not put yourself in any situation where feeling sleepy or falling asleep could put you (or other people) at risk of serious injury or death. Do not take part in these activities until you are no longer affected.

Talk to your doctor if this causes problems for you.

Ropinirole Krka contains lactose

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

3. How to take Ropinirole Krka

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

Use in children and adolescents

Do not give Ropinirole Krka to children. Ropinirole Krka is not normally prescribed for people under 18.

You may be given Ropinirole Krka on its own to treat the symptoms of your Parkinson’s disease. Or you may be given Ropinirole Krka as well as another medicine called L-dopa (also called levodopa). If you are taking L-dopa you may experience some uncontrollable movements (dyskinesias) when you first start taking Ropinirole Krka. Tell your doctor if this happens, as your doctor may need to adjust the doses of the medicines you are taking.

Ropinirole Krka tablet(s) are designed to release drug over a 24hr period. If you have a condition where your medicine passes through your body too quickly, e.g., diarrhoea, the tablet(s) may not dissolve completely and may not work properly. You may see tablet(s) in your stool. If this happens, let your doctor know as soon as possible.

How much Ropinirole Krka will you need to take?

It may take a while to find out the best dose of Ropinirole Krka for you.

The recommended starting dose of Ropinirole Krka prolonged-release tablets is 2

mg once daily for the first week. Your doctor may increase your dose to 4

mg of

Ropinirole Krka prolonged-release tablets once daily, from the second week of treatment. If you are very elderly, your doctor may increase your dose more slowly. After that, the doctor may adjust your dose until you are taking the dose that is best for you. Some people take up to 24 mg of Ropinirole Krka prolonged-release tablets each day.

If at the start of your treatment, you experience side effects that you find difficult to tolerate, speak to your doctor. Your doctor may advise you to switch to a lower dose of ropinirole immediate-release tablets which you will take three times a day.

Do not take any more Ropinirole Krka than your doctor has recommended.

It may take a few weeks for Ropinirole Krka to work for you.

Taking your dose of Ropinirole Krka

Take Ropinirole Krka once a day, at the same time each day.

Swallow your Ropinirole Krka prolonged-release tablet(s) whole, with a glass of water.

DO NOT break, chew or crush the prolonged-release tablet(s). If you do, there is a danger you could overdose, because the medicine will be released into your body too quickly.
