What does it do?

Selegiline is used to treat Parkinson’s disease. It increases the amount of dopamine in your brain.

Before you start

• Tell your doctor if you have heart, blood pressure, or mental health problems.
• Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you take it?

Take selegiline regularly as directed with a glass of water.

What if you forget a dose?

If it is nearly time for your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take the missed dose as soon as you remember. Do not take two doses at the same time.

Can you take other medicines?

Some medicines available without a prescription may react with selegiline including:

• cold and flu medicines containing oxymetazoline (e.g. Drixine®), phenylephrine (e.g. Sudafed PE®) or xylometazoline (e.g. Otrivin®)
• some migraine medicines, such as sumatriptan (e.g. Sumagran Active®)

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products (e.g. St John's wort) or recreational drugs (e.g. ecstasy).
