Pregnancy, breastfeeding and fertility

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before this medicine is given.

Pregnancy

Treatment with Melphalan is not recommended during pregnancy because it may cause permanent damage to a foetus. If you are already pregnant, it is important to talk to your doctor before being given Melphalan. Your doctor will consider the risks and benefits to you and your baby of treatment with Melphalan.

Reliable contraceptive precautions must be taken to avoid pregnancy whilst you or your partner are having this injection/infusion.

Breastfeeding

It is unknown whether Melphalan is excreted in human breast milk. Do not breastfeed while being given Melphalan.

Fertility

Melphalan can affect ovaries or sperm, which may cause infertility (inability to have a baby). In women, menstruation can stop (amenorrhoea) and in men, a complete lack of sperm can be observed (azoospermia) as a result of Melphalan treatment. Therefore men are advised to have a consultation on sperm preservation before treatment.

Male and female contraception

It is recommended that men who are receiving Melphalan do not father a child during treatment and up to 3 months afterwards. Talk to your doctor if you would like to use effective and reliable contraceptives.

Driving and using machines

Effects on the ability to drive and operate machinery in patients taking this medicine have not been studied. It is not expected that this medicine will affect the ability to drive or operate machines.

Melphalan contains sodium

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

Melphalan contains ethanol (alcohol)

This medicine contains 5% ethanol (alcohol), equivalent to 10 ml beer or 2.4 ml wine per dose. Harmful for those suffering from alcoholism.

Method of administration

Melphalan can be given

• as an infusion (drip) into your vein
• into an artery, administered to a certain body part (perfusion).

How much Melphalan is given

Your doctor will decide how much Melphalan you will be given. The amount of Melphalan depends on

• your body weight or body surface area (a specific measurement taking into account your weight and your size)
• other drugs you are having
• your disease
• your age
• whether or not you have kidney problems.

When you are given Melphalan, your doctor will take regular blood tests. This is to check the number of cells in your blood. Your doctor may change your dose as a result of these tests.

Risk of blood clots(thromboembolic events)

Your doctor will decide if you should receive a preventive treatment for blood clots in the veins. This applies during the first 5 months of treatment, or if you have an increased risk for developing a blood clot in the veins.

Use in children

Melphalan is only rarely used in children. Dosing guidelines for children are not available.

Use in elderly

There are no specific dosage adjustments for the elderly.

Use in patients with impaired renal function

If you have a kidney problem, your doctor will usually give you a lower dose than other adults.

If you are given more Melphalan than you should

Your doctor will give you Melphalan so it is unlikely that you will receive too much. If you think you have been given too much or have missed a dose, tell your doctor or nurse.

If you forget to use Melphalan

Your doctor will give you Melphalan so it is unlikely that you will miss a dose of this medicine. If you think you have missed a dose, skip that dose and you will be given next dose at the next prescribed time. Do not use a double dose to make up for a forgotten dose.

If you stop using Melphalan

If you feel you should stop using this medicine, consult your doctor first.
