ABOUT THIS MEDICATION

What Mylan-Latanoprost/Timolol is used for:

Mylan-Latanoprost/Timolol is a combination of an ophthalmic prostaglandin drug (latanoprost) and an ophthalmic beta-blocking drug (timolol), both of which lower the pressure within the eye in different ways. The prostaglandin drug works by increasing the natural outflow of fluid from inside the eye. The beta- blocking drug works by decreasing the fluid production in the eye.

• if you have known hypersensitivity to latanoprost, timolol, benzalkonium chloride or any other ingredient in the product. (See What the medicinal ingredients are).

Each millilitre (mL) contains 50 micrograms of latanoprost and 5 milligrams of timolol as timolol maleate

PROPER USE OF THIS MEDICATION

Always use Mylan-Latanoprost/Timolol exactly as your doctor has told you.

Usual adult dose:

One drop of Mylan-Latanoprost/Timolol should be dropped into the affected eye(s) once daily.

Do not allow the dropper tip of the bottle to touch the eye or other surrounding structures, because this could contaminate the tip with common bacteria known to cause eye infections. Serious damage to the eye with subsequent loss of vision may result if you use eye drop solutions that have become contaminated. If you experience any type of eye condition or have surgery, immediately seek your doctor's advice concerning the continued use of the bottle you are using.

If you forget to use your eye drops at the usual time, wait until it is time for your next dose. If you put too many drops in your eye(s), you may feel some slight irritation.

Follow these steps to help you use Mylan-Latanoprost/Timolol properly:

1. 1. Wash your hands and sit or stand comfortably. If you wear contact lenses, remove them before using your eye drops.

1. 2. Twist off the outer protective cap from the bottle.

1. 3. Unscrew the inner cap of the bottle.

1. 4. Once the bottle is opened, hold it in one hand and steady your thumb against your brow or the bridge of your nose.
2. 5. Use your index finger to gently pull down the lower eyelid of the affected eye(s) to create a pocket for the drop.
3. 6.

   Gently press, or lightly tap, the side of the bottle to allow only a single drop to fall into the pocket. Do not let the tip of the bottle touch your eye. 7. Close your eye for 2 to 3 minutes.

   1. 8. If your doctor has told you to use drops in both eyes, repeat the process for the other eye. Mylan-Latanoprost/Timolol should be used until your doctor tells you to stop.

Mylan-Latanoprost/Timolol is not recommended for use in children.

Missed Dose:

If you forget one dose of Mylan-Latanoprost/Timolol, continue with the next dose as normal. Do not double dose.

SIDE EFFECTS AND WHAT TO DO ABOUT THEM

In some patients, Mylan-Latanoprost/Timolol may cause a gradual change in eye color by increasing the amount of brown pigment in the iris (the colored part of the eye). This change may not be noticeable for several months to years. This effect may be more noticeable in patients with eye colors that are mixtures of green and brown, blue/gray and brown, or yellow and brown. The brown pigment may gradually spread outward toward the outside edge of the iris. However, the entire iris or parts of it may become more brownish in appearance. This change may be more noticeable if you are only treating one eye. Therefore, there is the potential for permanent difference in the colour between the treated and the untreated eyes. Your doctor will examine you regularly to make sure that your medication is working and look for changes in eye color. If you should experience any changes in eye color, your doctor can stop treatment. However, any color change that has already occurred may be permanent, even after the medication is stopped.

Mylan-Latanoprost/Timolol may also cause your eye lashes to darken, appear thicker and longer than they usually do. A very small number of people may notice their eye lid skin looks darker after using Mylan-Latanoprost/Timolol for sometime. These changes may be more noticeable if you are only treating one eye.

When using Mylan-Latanoprost/Timolol, you might feel as if there is something in your eye(s). Your eye(s) might water and become red. As with other eye drops, if your vision is blurred when you first put your drops in, wait until this wears off before you drive or operate machinery. A few people using Mylan-Latanoprost/Timolol have developed a skin rash.

A few people may experience changes in their vision, sometimes in combination with a red and sore/painful eye. These changes do not always occur right after administering the drops, and if they occur, you may find that reading and seeing fine details more difficult. Although unlikely, if you experience any of these changes, stop using Mylan-Latanoprost/Timolol and contact your doctor immediately.

Mylan-Latanoprost/Timolol may cause the following side effects as well.

Common side effects: eye irritation, including burning and stinging, inflammation of the eye lid and eye pain, upper respiratory tract infection.

Effects on the body: headache and skin rash, loss of appetite, sore muscles, low blood sugar in diabetics, dry eyes, nervous system effects including anxiety, nervousness, dizziness, confusion, disorientation, insomnia, hallucinations.

Be sure to tell your doctor (or pharmacist) if you notice any other unwanted side effects.
