Timoptic

Generic name: Timolol
Brand names: Timoptic-XE, Timoptic, Betimol

Why is Timoptic prescribed?

Timoptic is a topical medication (applied directly in the eye) that effectively reduces internal pressure in the eye. Timoptic is used in the treatment of glaucoma to lower elevated eye pressure that could damage vision and, with other glaucoma medications, to further reduce pressure in the eye.

Most important fact about Timoptic

Although Timoptic eyedrops are applied only to the eye, the medication is absorbed and may have effects in other parts of the body. If you have diabetes, asthma, or other respiratory disease, or decreased heart function, make sure your doctor is aware of the problem.

How should you use Timoptic?

Timoptic should be used exactly as prescribed by your doctor.

If you are using Timoptic in Ocudose, use the medication as soon as you open the individual unit and throw out any leftover solution.

If you are using Timoptic-XE, invert the closed container and shake it once--and only once--before each use.

If you need to use other eye medications along with Timoptic, use them at least 10 minutes before you instill Timoptic. Allow 5 minutes with Betimol.

If you wear contact lenses, remove them before using Timoptic and wait 15 minutes before reinserting them.

Handle the Timoptic solution carefully to avoid contamination. Do not let the tip of the dispenser actually touch the eye. Do not enlarge the hole in the dispenser tip; it is designed to provide just 1 drop. Do not wash the dispenser tip with water, soap, or any other cleaner.

To administer Timoptic, follow these steps:

1. Wash your hands thoroughly.
2. Tilt your head back and gently pull your lower eyelid down to form a pocket.
3. Turn the bottle upside down, holding it with your thumb or index finger over the Finger Push Area.
4. Press the bottle lightly until a single drop falls into the eye.
5. Repeat steps 3 and 4 with the other eye if necessary.
6. Replace the cap firmly.

--If you miss a dose...

If you use Timoptic once a day, apply it as soon as you remember. If you do not remember until the next day, skip the dose you missed and go back to your regular schedule. Do not take 2 doses at once. If you use it more than once a day, apply it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Do not take 2 doses at once.

--Storage instructions...

Store at room temperature, protected from light. Keep from freezing.

What side effects may occur?

Side effects cannot be anticipated. If any side effects develop or change in intensity, tell your doctor immediately. Only your doctor can determine whether it is safe to continue using Timoptic. If Timoptic is absorbed into the bloodstream, it can cause additional side effects.

• More common side effects may include:
  Burning and stinging on instillation of the drug

Why should Timoptic not be prescribed?

Do not use Timoptic if you have bronchial asthma, a history of bronchial asthma, or other serious breathing disorders such as emphysema, slow heartbeat, heart block (conduction disorder), active heart failure, or inadequate blood supply to the circulatory system (cardiogenic shock), or if you have ever had an allergic reaction or are sensitive to Timoptic or any of its ingredients.

Special warnings about Timoptic

Use Timoptic cautiously if you have a history of heart failure or poor circulation to the brain.

Tell your doctor if you have any type of allergy. The frequency and severity of allergic reactions may increase while you are using Timoptic.

Timoptic may mask the symptoms of low blood sugar. If you are diabetic, discuss this possibility with your doctor.

Tell your doctor or dentist that you are using Timoptic if you have a medical emergency or before you have surgery or dental treatment.

Timoptic may mask symptoms of an overactive thyroid. If your doctor suspects you have excessive thyroid function, he or she will manage your case carefully to avoid such symptoms as rapid heartbeat, which can occur when the drug is withdrawn too abruptly.

Timoptic"s antiglaucoma effects may decrease if you use the medication for a long time.

Some older individuals may be more sensitive to this product than younger people. If you develop an eye infection, suffer an eye injury, or have eye surgery, check with your doctor. You may need to stop using Timoptic.

Possible food and drug interactions when taking Timoptic

If Timoptic is used with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining Timoptic with the following:

Epinephrine (EpiPen)
Catecholamine-depleting drugs, such as blood pressure drugs that contain reserpine (Serpasil)
Calcium antagonists such as Cardizem and Isoptin
Clonidine (Catapres, Clorpres, Combipres)
Digitalis (Lanoxin)
Quinidine (Quinaglute, Quinidex)

Timoptic should not be used with other topical beta blockers and should be used with caution if you are taking oral beta blockers such as Inderal and Tenormin.

Special information if you are pregnant or breastfeeding

If you are pregnant or plan to become pregnant, inform your doctor immediately. No information is available about the safety of using Timoptic during pregnancy.

Timolol appears in breast milk and may harm a nursing infant. If using Timoptic is essential to your health, your doctor may advise you to stop breastfeeding until your treatment is finished.
