Based on long-term experience, no effects on male and female fertility are expected.

NEOMAG contains Aspartame (E951)

This medicine contains 10 mg aspartame in each tablet which is equivalent to 6.3 mg/g.

Aspartame is a source of phenylalanine. It may be harmful if you have phenylketonuria (PKU), a rare genetic disorder in which phenylalanine builds up because the body cannot remove it properly.

How to take it

Always take NEOMAG exactly as your doctor or nurse has told you. Check with your doctor, pharmacist or nurse if you are not sure.

The amount of Neomag that you will be prescribed will depend on your particular needs. Neomag tablets can be divided into quarters and chewed or swallowed with water.

Adults, including the elderly The recommended dose is 1-2 tablets three times a

day. Your doctor may decide to monitor your magnesium levels at regular intervals.

Children and Adolescents

NEOMAG should only be used if a doctor has decided that the benefit of treatment outweighs any potential tisk. Children need to be monitored regularly and have their dose adjusted.

The recommended doses for children and adolescents aged 4 years to 18 years are shown below:

Age range Recommended dose 12 to 18 years 1 tablet three times daily 4 to 12 years 1 tablet twice daily

NEOMAG is not recommended for children under 4 years of age because there is not enough information about the use of NEOMAG in this age group.

Patients with poor kidney function may need to be monitored regularly and have their dose adjusted

If you take more NEOMAG than you should

Technical information intended for healthcare professionals (doctors and pharmacists). The Summary of Product Characteristics (SmPC) is the official document approved by the MHRA/EMA. It does not replace the patient leaflet or a doctor’s advice.

4.1. Therapeutic indications

Neomag 4mmol Chewable Tablets are indicated as oral magnesium supplements for the treatment of patients with chronic magnesium loss or hypomagnesaemia as diagnosed by a doctor.

Neomag 4mmol Chewable Tablets are also indicated for adult patients with hypomagnesaemia due to the concomitant administration of loop and thiazide diuretics or other drugs which cause hypomagnesaemia.

4.2. Posology and method of administration

Posology

Patients with severe, symptomatic hypomagnesaemia should receive intravenous magnesium repletion for acute recovery of magnesium levels prior to receiving Neomag.

It is recommended that serum magnesium levels should be monitored at regular intervals (e.g. every 3-6 months), particularly in children and in patients with renal impairment.

Adults (> 18 years): The dosage regimen should be adjusted according to the serum total magnesium level of the individual patient. Starting doses for adult patients are recommended as 4-8 mmol (1-2 tablets) administered 3 times a day. This equates to a total dose of 12 to 24 mmol per day taken in divided doses.

Elderly: No dose adjustment is necessary.

Paediatric population: Neomag tablets should only be used if the benefits of treatment outweigh any potential risks and under the supervision of physicians experienced in the management of children with hypomagnesaemia.

Children: below 4 years: Not recommended as there is insufficient information regarding the use of Neomag tablets in this age group.

Children: 4 to 12 years: The dosage regimen should be adjusted according to the serum total magnesium level of the individual patient. A starting dose for children 4 to 12 years is recommended as 4 mmol (1 tablet) administered 2 times a day. This equates to a total dose of 8 mmol per day taken in divided doses.

Children: 12 to 18 years: The dosage regimen should be adjusted according to the serum total magnesium level of the individual patient. A starting dose for children 12 to 18 years is recommended as 4 mmol (1 tablet) administered 3 times a day. This equates to a total dose of 12 mmol per day taken in divided doses.

Patients with Renal Impairment: Neomag is contraindicated in patients with severe renal impairment (see Section 4.3). There is no dose adjustment necessary in patients with mild to moderate renal impairment.

Method of administration

The tablet may be broken into quarters and chewed or swallowed with water.

Co-Administration of Potassium and Calcium Supplements: Administration of potassium and calcium together with magnesium may be necessary since associated loss of these cations is common in severe magnesium deficiency.

4.3. Contraindications

Do not administer Neomag tablets if there is evidence of hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

Neomag is contraindicated in patients with severe renal impairment (glomerularfiltration rate < 30 ml/min).

Neomag should not be administered to patients with phenylketonuria as Neomag tablets contain Aspartame.

Neomag should not be administered to patients with hyperphosphataemia as Neomag tablets contain phosphate.

4.5. Interaction with other medicinal products and other forms of interaction

Cardiovascular drugs: Digoxin and loop diuretics are magnesiuretic drugs and may affect magnesium balance. Magnesium deficiency may enhance digoxin toxicity.

As magnesium and other medicinal products may mutually influence each other's absorption, a time interval of 2 to 3 hours should generally be respected if possible.

This specifically applies to:

• Cellulose sodium phosphate; edetate disodium: concurrent use with magnesium supplements may result in binding of magnesium; patients should be advised not to take magnesium supplements within 1 hour of cellulose sodium phosphate or edentate disodium.

• Fluorides and tetracycline: if they must be used, the doses must be separated by 2 to 3 hours or more to prevent their admixture in the gut.

• Aminoquinolines, quinidine and quinidine derivatives, nitrofurantoin, penicillamine, iron, bisphosphonates (such as alendronate and risedronate), eltrombopag, nitroxoline: to avoid impairment of absorption, magnesium preparations should be taken 3 to 4 hours before or after the administration of those drugs.

Because of increased magnesium losses, a dose adjustment of magnesium may be necessary when taking the following substances:

• Aminoglycoside antibiotics, cisplatin and ciclosporin A

• Diuretics (such as thiazide and furosemide),

• EGF-receptor antagonists (such as cetuximab and erlotinib),

• proton pump inhibitors (such as omeprazole and pantoprazole) and

• viral DNA polymerases-inhibiting foscarnet, pentamidine, rapamycin and amphotericin B

In addition, other electrolyte disturbances, such as hypokalaemia and hypocalcaemia, should be looked for in these patients with hypomagnesaemia.

For further information on mechanisms of drug interactions see section 5.2.

4.6. Fertility, pregnancy and lactation

Fertility

Based on long-term experience, no effects of magnesium on male and female fertility are anticipated.

Pregnancy

The effectiveness and safety of Neomag has not been established in pregnant women. Neomag tablets should only be used in pregnancy if the benefits of the treatment outweigh any potential risks. However, long-term data available from treatment of pre-eclampsia do not indicate malformative or feto/neonatal toxicity of magnesium.

Administration of aminoglycoside antibiotics should be avoided during this period, as there are indications of interactions (see Section 4.5).

Lactation

Neomag can be used during breast-feeding. Magnesium glycerophosphate /its metabolites are excreted in human milk, but at therapeutic doses of Neomag no effects on the breastfed newborns/infants are anticipated.

4.7. Effects on ability to drive and use machines

Neomag has no or negligible influence on the ability to drive and use machines.

4.9. Overdose

Symptoms: Hypermagnesaemia characterised by flushing, thirst, hypotension, drowsiness, nausea, vomiting, confusion, loss of tendon reflexes due to neuromuscular blockade, muscle weakness, respiratory depression, cardiac arrhythmias, coma and cardiac arrest.

Treatment of Iatrogenic Hypermagnesaemia and Overdose: When hypermagnesaemia is found, magnesium therapy should be withdrawn and this is all that is needed in most patients with mild to moderate hypermagnesaemia. In patients with symptomatic hypermagnesaemia, serum magnesium should be lowered and the effects of hypermagnesaemia antagonised. Calcium antagonises the toxic effects of magnesium and therefore patients with severe magnesium intoxication should be given intravenous calcium gluconate as a bolus followed by an infusion. Administration of glucose and insulin may also help to promote magnesium entry into cells. If renal function is normal adequate fluids should be given to assist removal of magnesium from the body. If the patient is in renal failure, peritoneal or haemodialysis against a low magnesium dialysis fluid will rapidly and effectively lower the serum magnesium concentration.
