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 already 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 Zofran Zydis, as Zofran Zydis may harm the fetus. 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 will check if you are pregnant and will perform a pregnancy test before you start treatment with Zofran Zydis.

Women of childbearing age must use an effective method of contraception during treatment with Zofran Zydis. Ask your doctor about the options for contraceptive methods.

If you become pregnant during treatment with Zofran Zydis, tell your doctor.

Driving and using machines

Zofran Zydis is unlikely to affect your ability to drive or use machines.

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

This medicine contains 1.25 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 cannot be eliminated properly).

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 0.00005 mg of benzyl alcohol in each oral lyophilisate.

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