Medrone tablets 100 mg – patient leaflet, side effects, dosage

1. What Medrone is and what it is used for

This medicine contains methylprednisolone, which belongs to a group of medicines called steroids. Their full name is corticosteroids. Corticosteroids are produced naturally in your body and are important for many body functions. Boosting your body with extra corticosteroid such as Medrone can help following surgery (e.g. organ transplants), injuries or other stressful conditions. These include inflammatory or allergic conditions affecting the:

• brain (e.g., tuberculous meningitis)
• bowel and gut (e.g., Crohn’s disease and ulcerative colitis)

• blood or blood vessels (e.g., leukaemia or arteritis, inflammation of the arteries)

  • joints (e.g., rheumatic fever)
  • lungs (e.g., asthma, tuberculosis)
  • muscle (e.g., dermatomyositis and polymyositis)

  • skin (e.g., pemphigus vulgaris, an auto-immune disorder in which the body’s

    immune system is overactive causing the skin to blister)

Medrone may be prescribed to treat conditions other than those listed above. You must talk to a doctor if you are unsure why you have been given this medicine, if you do not feel better or if you feel worse.

2. What you need to know before you take Medrone

Do not take Medrone

• If you think you have ever suffered an allergic reaction, or any other

  type of reaction after being given Medrone or any of the other ingredients of this medicine (listed in section 6). An allergic reaction may cause a skin rash or reddening, swollen face or lips or shortness of breath.

• If you have any serious fungal infection such as a serious fungal infection in

  your lungs or oesophagus (the tube that connects your mouth with your stomach) or any other infection which is not being treated with an antibiotic or antiviral medicine.

• If you have recently had or are about to have any vaccination. If you get a rash or another symptom of an infection tell your doctor immediately.

Warnings and precautions

Talk to your doctor or pharmacist before taking this medicine if you have any of the following conditions.

Your doctor may have to monitor your treatment more closely, alter your dose or give you another medicine.

• Chickenpox, measles or shingles. If you think you have been in contact with

  someone with chickenpox, measles or shingles and you have not already had these illnesses, or if you are unsure if you have had them.

• Worm infestation (e.g., threadworm).

• Severe depression or manic depression (bipolar disorder). This includes having

  had depression before while taking steroid medicines like Medrone, or having a family history of these illnesses.

• Diabetes (or if there is a family history of diabetes).
• Fits or seizures.

• Glaucoma (increased pressure in the eye) or if there is a family history of

  glaucoma, or if you have cataracts.

  • Contact your doctor if you experience blurred vision or other

    visual disturbances.

  • Viral (e.g., herpes) or fungal eye infection.
  • You recently suffered a heart attack.
  • Heart problems, including heart failure.
  • Hypertension (high blood pressure).
  • Hypothyroidism (an under-active thyroid).
  • Hyperthyroidism (an over-active thyroid gland).

  • Pancreatitis (inflammation of the pancreas which causes severe

    pain in the abdomen and back).

  • Peritonitis (inflammation of the thin lining (peritoneum) around the

    gut and stomach).

  • Kidney or liver disease.

  • Scleroderma (also known as systemic sclerosis, an autoimmune

    disorder), because the risk of a serious complication called scleroderma renal crisis may be increased. Signs of scleroderma renal crisis include increased blood pressure and decreased urine production.

  • Kaposi’s sarcoma (a type of skin cancer).

  • Muscle problems (pain or weakness) have happened while taking

    steroid medicines like Medrone in the past.

  • Myasthenia gravis (muscle disease with muscle fatigue), or if

    during treatment you develop muscular disorders. • Osteoporosis (brittle bones).

  • Pheochromocytoma (a rare tumour of adrenal gland tissue. The

    adrenal glands are located above the kidneys).

  • Skin abscess.

  • Stomach ulcer or other serious stomach or intestinal problems. • Thrombophlebitis - vein problems due to thrombosis (clots in the

    veins) resulting in phlebitis (red, swollen and tender veins). • Tuberculosis (TB) or if you have suffered tuberculosis in the past. • Cushing’s disease (condition caused by an excess of cortisol

    hormone in your body).

  • Brain injury due to trauma (injury).
  • Unusual stress.

Contact your doctor promptly if you experience muscle weakness, muscle aches, cramps and stiffness while using methylprednisolone. These can be symptoms of a condition called Thyrotoxic Periodic

Paralysis which may occur in patients with an over-active thyroid gland (hyperthyroidism) who are treated with methylprednisolone. You may need additional treatment to alleviate this condition. Tumour lysis syndrome (TLS) can occur after treatment of a fast-growing cancer, such as blood cancers or solid tumours. Symptoms of TLS include muscle cramping, muscle weakness, confusion, irregular heartbeat, visual loss or visual disturbances, and shortness of breath. Your doctor will monitor you closely, especially if you are at high risk of developing tumour lysis syndrome. Contact your doctor immediately, if you experience any muscle pain, muscle weakness, and /or red-brown change in the colour of your urine as this might be a sign of rhabdomyolysis which is a severe condition involving breakdown of your muscles.

Other medicines and Medrone

  • Rifampicin and rifabutin - antibiotics used to treat tuberculosis

    (TB).

  • Tacrolimus - used following an organ transplant to prevent

    rejection of the organ.

  • Vaccines - tell your doctor or nurse if you have recently had, or are

    about to have any vaccination. You must not have ‘live’ vaccines while using this medicine. Other vaccines may be less effective. If you are taking long term medication(s)

If you are being treated for diabetes, high blood pressure or water retention (oedema) tell your doctor as he/she may need to adjust the dose of the medicines used to treat these conditions. Before you have any operation tell your doctor, dentist or anesthetist that you are taking Medrone.

If you require a test to be carried out by your doctor or in hospital it is important that you tell the doctor or nurse that you are taking Medrone. This medicine can affect the results of some tests. Pregnancy and breast-feeding

If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine, as it could slow the baby’s growth.

There is a risk of low birth weight of a baby; this risk can be minimised by taking the lowest effective dose of the corticosteroids. Cataracts have been observed in infants born to mothers treated with long-term corticosteroids during pregnancy.

If you are breast-feeding, ask your doctor or pharmacist for advice, as small amounts of corticosteroid medicines may get into breast milk.

Driving and using machines

Undesirable effects, such as dizziness, vertigo, visual disturbances and fatigue are possible after treatment with corticosteroids. If you are affected do not drive or operate machinery.

Medrone contains sodium

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

3. How to take Medrone

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

Steroid Cards

Remember to always carry a Steroid Treatment Card. Make sure your doctor or pharmacist has filled out the details of your medicine, including the dose and how long you will require steroid treatment.

You should show your steroid card to anyone who gives you treatment (such as a doctor, nurse or dentist) while you are taking Medrone, and for 3 months after you stop taking the tablets.

If you are admitted to hospital for any reason always tell your doctor or nurse that you are taking Medrone. You can also wear a medic-alert bracelet or pendant to let medical staff know that you are taking a steroid if you have an accident or become unconscious.

Adults

The normal daily dose is between 4 mg and 360 mg per day, depending on your condition and how severe it is. Your doctor will prescribe the lowest dose possible.

Your doctor may tell you to take your daily dose all in one go, split your daily dose throughout the day, or take it every other day at 8.00 am.

Swallow the tablets whole with a drink of water. The score line is not intended for breaking the tablet.

Do not eat grapefruit or drink grapefruit juice while taking Medrone. If you are being given Medrone because your body cannot make its own corticosteroids, your doctor may also want you to take a second type of steroid to help your salt balance.

Your doctor may prescribe a higher dose at the start of your treatment to bring your condition under control.

When your doctor is happy that your condition has improved your dose will be reduced gradually. Normally the dose will be reduced by not more than 2 mg every 7 to 10 days.

Elderly:

Your doctor may want to see you more regularly to check how you are getting on with your tablets.

Children and adolescents:

Corticosteroids can affect growth in children so your doctor will prescribe the lowest dose that will be effective for your child. Your doctor may tell you to give your child this medicine on every other day. If you take more Medrone than you should

It is important that you do not take more tablets than you are told to take. If you accidentally take too many tablets, seek medical attention straight away.

If you forget to take your Medrone

Wait and take the next dose as normal. Do not take a dose to make up for the forgotten one but tell your doctor or pharmacist what had happened.

Stopping/reducing the dose of your Medrone

Your doctor will decide when it is time to stop your dose. You must not stop taking Medrone suddenly, especially if you: • have had more than 6 mg Medrone daily for more than 3 weeks • have been given high doses of Medrone (more than 32 mg daily)

even if it was only for 3 weeks or less

• have already had a course of corticosteroid tablets or injections in the last year

  PAA246816

• already had problems with your adrenal glands (adrenocortical insufficiency)

  before you started this treatment

• take repeat doses in the evening.

You will need to come off Medrone slowly to avoid withdrawal symptoms. These symptoms may include itchy skin, fever, muscle and joint pains, runny nose, sticky eyes, loss of appetite, nausea, vomiting, headache, feeling tired, peeling skin and weight loss.

If your symptoms seem to return or get worse as your dose of Medrone is reduced tell your doctor immediately.

Mental problems while taking Medrone

Mental health problems can happen while taking steroids like Medrone (see section 4).

• These illnesses can be serious.
• Usually they start within a few days or weeks of starting the medicine. • They are more likely to happen at high doses.

• Most of these problems go away if the dose is lowered or the medicine is stopped.

  However if the problems do happen they might need treatment. Talk to a doctor if you (or someone using this medicine) shows any signs of mental problems. This is particularly important if you are depressed, or might be thinking about suicide. In a few cases mental problems have happened when doses are being lowered or stopped.

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

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them. Your doctor will have given you this medicine for a condition which if not treated properly could become serious.

These side effects may occur with certain frequencies, which are defined as follows:

• common: may affect up to 1 in 10 people.
• rare: may affect up to 1 in 1,000 people.
• not known: frequency cannot be estimated from the available data.

In certain medical conditions medicines like Medrone (steroids) should not be stopped abruptly. If you suffer from any of the following symptoms, seek
