Miostat

Carbachol helps lower eye pressure by increasing the flow of fluid that drains from the eye.

Miostat (for the eye) is used to lower pressure in the eye after cataract surgery.

Miostat may also be used for other reasons not mentioned in this medication guide.

Before you receive treatment with Miostat, inform your doctor about all your medical conditions or allergies, as well as all the medicines you are taking. Also, let your doctor know if you are pregnant or breast-feeding. In some situations, you may not be able to use this medicine, or you may require a dose adjustment or special precautions.

You should not be treated with Miostat if you are allergic to it.

To make sure Miostat is safe for you, tell your doctor if you have any of these other conditions:

• swelling of your iris (the colored part of your eye);
• a detached retina;
• heart failure;
• asthma;
• a stomach ulcer;
• an overactive thyroid;
• urination problems;
• Parkinson's disease; or
• an allergy to latex.

It is not known whether Miostat will harm an unborn baby. Tell your doctor if you are pregnant.

It is not known whether carbachol ophthalmic passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Miostat may cause serious side effects. Call your doctor right away if you have:

• new or sudden vision problems;
• seeing "floaters" in your vision; or
• problems urinating.

Common side effects of Miostat may include:

• blurred vision;
• flushing (warmth, redness, or a tingly feeling);
• stomach pain or upset;
• headache; or
• a tight feeling in your bladder.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.

Miostat is given as an injection into your eye. Your doctor will use a medicine to numb your eye before giving you the injection. You will receive this injection in your doctor's office or other clinic setting.

Since Miostat is administered by a healthcare professional during surgery, it does not have a daily dosing schedule.

Since Miostat is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.

This medicine may cause blurred vision and may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly.

It is not likely that other drugs you take by mouth or inject will affect carbachol used in the eyes. However, many drugs can interact with each other. Inform all of your healthcare providers about all the medicines you use, including prescription and over-the-counter medicines, vitamins, and herbal products.
