Pregnancy, breast-feeding and fertility

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.

Zofran Zydis should not be used during the first trimester of pregnancy. This is because Zofran Zydis may slightly increase the risk of a baby being born with a cleft lip and/or cleft palate.

If you are a woman of childbearing age, you are advised to use an effective method of contraception.

If you are a woman of childbearing age, your doctor or nurse should check if you are pregnant and perform a pregnancy test before you start treatment with Zofran Zydis.

Zofran Zydis contains aspartame (E951), sodium methyl parahydroxybenzoate (E219), sodium propyl parahydroxybenzoate and benzyl alcohol (E1519)

This medicine contains 0.625 mg of aspartame per oral lyophilisate. Aspartame is a source of phenylalanine, which may be harmful for people with phenylketonuria (a rare genetic disorder in which phenylalanine accumulates in the body because it is not properly broken down).

This medicine may cause allergic reactions (which may be delayed) because it contains sodium methyl parahydroxybenzoate and sodium propyl parahydroxybenzoate.

This medicine contains less than 1 mmol of sodium (23 mg) per oral lyophilisate, which is essentially "sodium-free".

This medicine contains 0.000025 mg of benzyl alcohol in each oral lyophilisate.

Benzyl alcohol may cause allergic reactions. Benzyl alcohol has been linked to a risk of serious side effects, including breathing problems ("gasping syndrome") in children. Do not give this medicine to your newborn (up to 4 weeks of age) unless your doctor has recommended it. This product should not be used for more than one week in children under 3 years of age unless your doctor or pharmacist has indicated it. Ask your doctor or pharmacist if you are pregnant or breast-feeding or if you have liver or kidney disease. This is because large amounts of benzyl alcohol can build up in your body and cause side effects (metabolic acidosis).
