Everyday use and best practices

For glaucoma, dosing in the evening is generally recommended. Taking the medicine at the same time each day is essential for maintaining stable intraocular pressure.

Bimatoprost is an eye drop, so meals do not matter. Establishing a routine, perhaps using a phone reminder, can help ensure regular use.

Safety priorities

Those with known allergies to bimatoprost or any of its components should not use it. Individuals with active eye infections should avoid these eye drops until the infection has been treated.

If you experience any vision changes following application, avoid driving or operating machinery until your vision is clear.

Dosage and adjustments

The dose of bimatoprost is typically one drop in the affected eye(s) once daily, in the evening. Do not exceed this dose. For elderly users or those with liver and kidney impairments, caution is warranted and monitoring for adverse effects is especially important.

What’s inside and how it works

Bimatoprost is a prostaglandin analogue that lowers intraocular pressure (IOP). It imitates the action of natural prostaglandins, enhancing uveoscleral outflow, which improves the drainage of fluid in the eye and helps reduce the risk of damage to the optic nerve from elevated pressure. An overview of the ingredients:

Main indications

Approved uses

Bimatoprost (Lumigan) is licensed in the UK for lowering raised intraocular pressure in open-angle glaucoma and ocular hypertension, preventing irreversible optic nerve damage.

Off-label uses in UK clinics

In some clinics bimatoprost is used to enhance eyelash growth; this is outside the UK licence of bimatoprost eye drops.

Interaction warnings

No significant food interactions are known for bimatoprost eye drops.

Patients using other eye preparations should consult their healthcare provider to avoid adverse effects. Suspected side effects can be reported through the Yellow Card scheme. Points to note:

• Concurrent use of multiple glaucoma therapies may increase local side effects.
• Historical reactions with other prostaglandin analogues can occur.
