Latanoprost

Date: September 2024, Version 1.0

Quick read

Latanoprost can be used in pregnancy if recommended by a doctor.

What is it?

Latanoprost eye drops (Lotacryn®, Monopost®, Xalatan®) are used to treat glaucoma.

Benefits

What are the benefits of using latanoprost?

Use of latanoprost eye drops can help to prevent sight problems (including blindness) in people with glaucoma.

Risks

Are there any risks of using latanoprost during pregnancy?

Latanoprost in eye drop form enters the woman’s bloodstream in small amounts. Only a handful of pregnant women using latanoprost have been studied, but overall there is no concern that its use causes problems.

Alternatives

Are there any alternatives to taking latanoprost?

Possibly. Other medicines can be used to treat glaucoma. You should let your GP, obstetrician or eye specialist know that you are using latanoprost so that they can make sure it is still right for you. If you have any questions about a medicine that you are offered in pregnancy you should discuss them with your doctor or midwife.

No treatment

What if I prefer not to take medicines to treat glaucoma?

It very important that glaucoma continues to be treated during pregnancy as stopping treatment can cause irreversible sight damage. Your doctor will only prescribe medicines when necessary and will be happy to talk to you about any concerns that you might have.

Will my baby need extra monitoring?

You will be offered a detailed scan at around 20 weeks of pregnancy as part of your routine antenatal care. No further monitoring will usually be necessary following use of latanoprost eye drops.

Are there any risks to my baby if the father used latanoprost?

We do not expect any increased risk to your baby if the father uses latanoprost.

Who can I talk to if I have questions?

How can I help to improve drug safety information for pregnant women in the future?

Our online reporting system (MyBump Portal) allows women who are currently pregnant to create a secure record of their pregnancy, collected through a series of questionnaires. You will be asked to enter information about your health, whether or not you take any medicines, your pregnancy outcome and your child's development. You can update your details at any time during pregnancy or afterwards. This information will help us better understand how medicines affect the health of pregnant women and their babies. Please visit the MyBump Portal to register.

General information
Sadly, miscarriage and birth defects can occur in any pregnancy.

Miscarriage occurs in about 1 in every 5 pregnancies, and 1 in every 40 babies are born with a birth defect. This is called the ‘background risk’ and happens whether medication is taken or not.

Most medicines cross the placenta and reach the baby. For many medications this is not a problem. However, some medicines can affect a baby’s growth and development.

If you take regular medication and are planning to conceive, you should discuss whether your medicine is safe to continue with your doctor/health care team before becoming pregnant. If you have an unplanned pregnancy while taking a medicine, you should tell your doctor as soon as possible.

If a new medicine is suggested for you during pregnancy, please make sure that the person prescribing it knows that you are pregnant. If you have any concerns about a medicine, you can check with your doctor, midwife or pharmacist.

Our Bumps information leaflets provide information about the effects of medicines in pregnancy so that you can decide, together with your healthcare provider, what is best for you and your baby.
