This may affect the dose you are given, or your doctor may want you to take other medicines at the same time.

• Taking this medicine may increase your risk of getting an infection. It may also mask the symptoms of an existing or developing infection and make it harder to find out what is wrong. If you develop an infection whilst on this medicine, you should talk to your doctor.
• If you have an accident, are ill, require surgery (even at the dentists) or you require a vaccination (particularly with ‘live virus’ vaccines) whilst taking or when you have finished taking Dexamethasone, you should inform the person treating you that you are taking or have taken steroids.
• If you have an allergy test, a suppression test (test for hormone levels) or a test for an infection, you should inform the person performing the test that you are taking Dexamethasone as it may interfere with the results.
• If you need a vaccination tell your doctor as it may not be effective or you may have a greater chance of getting an infection from a ‘live’ vaccine such as MMR, tuberculosis (TB), yellow fever or oral typhoid.
• If you have a doping test when taking this medicine, you may get a positive result.
• Your doctor may want to perform regular check ups on you while you are taking Dexamethasone:
  • They may be more frequent if you have other health problems (such as diabetes or kidney problems) or if you are elderly as any side effects may be more serious for you.
  • If a child is taking this medicine, it is important that their growth and development is checked at frequent intervals as Dexamethasone can cause children to grow more slowly.
  • If you are taking this medicine for a long time, regular (every 3 months) checks of your vision are recommended.
  • If you are taking high doses your doctor may monitor the levels of potassium in your blood. You may also find that your doctor will reduce the amount of salt in your diet and give you a potassium supplement whilst you are taking this medicine.
• If you take this medicine for more than 3 weeks, you should always carry a ‘steroid card’ which gives clear guidance on the special care to be taken when you are taking this medicine.

• Chickenpox, shingles and measles. It is important that whilst you are taking this medicine you avoid contact with anybody who has chickenpox, shingles or measles. If you think you may have had exposure to any of these diseases, you should consult your doctor immediately.
  • You should also inform your doctor if you have ever had infectious diseases such as measles or chickenpox and if you have had any vaccinations for these diseases in the past.

Some of the side effects of Dexamethasone may be more serious in older people. Your doctor may need to monitor you more closely for the following:

• diabetes
• getting infections
• thinning of the skin
• high blood pressure
• thinning of the bones (osteoporosis)
• low potassium levels in the blood (hypokalaemia).

If a child is taking this medicine, it is important that the doctor monitors their growth and development at frequent intervals. Dexamethasone should not be used routinely in preterm neonates with respiratory problems.

Please tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines you buy without a prescription, including herbal medicines. This is because some medicines may increase the effects of Dexamethasone and your doctor may wish to monitor you carefully if you are taking these medicines (including some medicines for HIV: ritonavir, cobicistat).

In particular, tell your doctor if you are taking any of the following:

• anticoagulant medicines which thin the blood (e.g. warfarin, coumarin)
• medicines that control pain or lower inflammation, such as aspirin (acetylsalicylic acid) or similar non-steroidal anti-inflammatory drugs (NSAIDs), such as indomethacin, hydrocortisone, cortisone and other corticosteroids. You should be carefully monitored if you are taking NSAIDs at the same time as taking Dexamethasone because you are more likely to get stomach or gut ulcers
• medicines used to treat diabetes such as insulin, metformin or sulfonylureas such as chlorpropamide
• medicines used to treat high blood pressure such as captopril or verapamil diuretics (water tablets)
• amphotericin B injection (used to treat infections)

You must read the package leaflet of all medicinal products to be taken in combination with Dexamethasone for information related to these medicines before starting treatment with Dexamethasone. When thalidomide, lenalidomide or pomalidomide is used, particular attention to pregnancy testing and prevention requirement is needed.

If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before taking Dexamethasone Soluble Tablets.

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.

Dexamethasone should only be prescribed during pregnancy, particularly in the first trimester, if the benefit outweighs the risks for the mother and child.

If you become pregnant during the use of the product, do not stop using it, but tell your doctor immediately that you are pregnant.

Dexamethasone is excreted in breast milk. It may influence the growth of your baby or cause other unwanted effects. Tell your doctor if you intend to breast-feed while taking this medicine.

You may experience dizziness when taking this medicine (see section 4: ‘Possible side effects’). This may affect your ability to drive. If this happens, do not drive or use tools or machinery.

Dexamethasone 10mg Soluble Tablets contain 32.8mg of sodium per tablet (main component of cooking/table salt). This is equivalent to 1.6% of the recommended maximum daily dietary intake of sodium for an adult.

Dexamethasone 10mg Soluble Tablets contain 9mg of benzoate salt per tablet.

Benzoate salt may increase jaundice (yellowing of the skin and eyes) in newborn babies (up to 4 weeks old).

The usual dose of Dexamethasone is 0.5mg to 10mg daily, depending on the disease being treated. In more severe disease conditions, doses above 10mg per day may be required. The dose should be titrated to the individual patient response and disease severity. In order to minimise side effects, the lowest effective possible dose should be used. Your doctor will decide your exact dose based on how serious your illness is.

The below mentioned dosing recommendations are given for guidance only. The initial and daily doses should always be determined based on individual patient response and disease severity.

• Cerebral oedema: Initial dose and duration of treatment depending on the cause and severity, 6-16mg (up to 24mg)/day orally, divided into 3-4 individual doses.
• Acute asthma: adults: 16mg /day for two days. Children: 0.6mg/kg body weight for one or two days.
• Croup: children: 0.15-0.6mg/kg in a single dose.
• Active skin diseases: depending on the nature and extent of the disease daily doses of 8-40mg, in some cases up to 100mg, which should be followed by down titration according to clinical need.
• Active phase of rheumatic system disorders: systemic lupus erythematosus 6-16mg/day.
• Active rheumatoid arthritis with severe progressive course form: running at fast destructive forms 12-16mg/day, with extra-articular manifestations 6-12mg/day.
• Idiopathic thrombocytopenic purpura: 40mg for 4 days in cycles.
• Tuberculous meningitis: Patients with grade II or III disease received intravenous treatment for four weeks (0.4mg/kg/day for week 1, 0.3mg/kg/day for week 2, 0.2mg/kg/day for week 3, and 0.1mg/kg/day for week 4) and then oral treatment for four weeks, starting at a total of 4mg per day and decreasing by 1mg each week. Patients with grade I disease received two weeks of intravenous therapy (0.3mg/kg/day for week 1 and 0.2mg/kg/day for week 2) and then four weeks of oral therapy (0.1mg/kg/day for week 3, then a total of 3mg/day, decreasing by 1mg each week).
• Palliative treatment of neoplastic diseases: initial dose and duration of treatment depending on the cause and severity, 3-20mg/day. Very high doses up to 96mg may also be used for palliative treatment. For optimal dosing and reduction of the number of tablets the combination of lower dose strengths (4 and 8 mg) and higher dose strengths (20mg or 40mg) can be used.
• Prophylaxis and treatment of emesis induced by cytostatic, emetogenic chemotherapy within antiemetic treatment: 8-20mg dexamethasone prior to chemotherapy treatment, then 4-16mg/day on day 2 and 3.
• Prevention and treatment of postoperative vomiting, within antiemetic treatment: single dose of 8mg before the surgery.
• Treatment of symptomatic multiple myeloma, acute lymphocytic leukaemia, acute lymphoblastic leukaemia, Hodgkin’s disease and non-Hodgkin’s lymphoma in combination with other medicinal products: the usual posology is 40mg or 20mg once per day.

The dose and administration frequency varies with the therapeutic protocol and the associated treatment(s). Dexamethasone administration should follow instructions for dexamethasone administration when described in the Summary of Product Characteristics of the associated treatment(s). If this is not the case, local or international treatment protocols and guidelines should be followed. Prescribing physicians should carefully evaluate which dose of dexamethasone to use, taking into account the condition and disease status of the patient.

For the long-term treatment of several conditions, after initial therapy, glucocorticoid treatment should be switched from dexamethasone to prednisone/prednisolone to reduce suppression on the function of the adrenal cortex.

Use in children: a single dose on alternate days.

Important: if a child is taking this medicine, it is important that the doctor monitors their growth and development at frequent intervals.
