Using timolol eye drops with other medicines and herbal supplements - Brand names: Eysano, Timoptol, Timoptol LA, Tiopex

Cautions with other medicines

If you are using other eye drops, they may work in a similar way to timolol. Tell your doctor if you are using:

• betaxolol
• levobunolol

Timolol eye drops are less likely to affect or be affected by other medicines than timolol tablets, but you should still tell your doctor if you’re taking any of the following medicines:

• medicines that can lower your blood pressure - these include, some antidepressants, nitrates (for chest pain), baclofen (a muscle relaxant), medicines for an enlarged prostate gland like tamsulosin, or Parkinson's disease medicines such as co-careldopa or levodopa
• medicines for an irregular heartbeat such as amiodarone or verapamil
• medicines for diabetes, particularly insulin – timolol eye drops may make it more difficult to recognise the warning signs of low blood sugar (hypoglycaemia)

Mixing timolol eye drops with herbal remedies and supplements

There's not enough information to say that herbal remedies and supplements are safe to take with timolol eye drops. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
