What special precautions should I follow?

Before using tetrahydrozoline eye drops,

  • tell your doctor and pharmacist if you are allergic to tetrahydrozoline or any other medications.
  • tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially eye medications, medications for high blood pressure, MAO inhibitors [phenelzine (Nardil) and tranylcypromine (Parnate)], and vitamins.
  • tell your doctor if you have any eye disease or infection, heart disease, high blood pressure, or an overactive thyroid gland.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while using tetrahydrozoline eye drops, call your doctor.
  • if you are having surgery, including dental surgery, tell your doctor or dentist that you are using tetrahydrozoline eye drops. You may have to stop using tetrahydrozoline eye drops for a short time.
  • tell your doctor if you wear soft contact lenses. If the brand of tetrahydrozoline eye drops you are using contains benzalkonium chloride, wait at least 15 minutes after using the medicine to put in soft contact lenses.

What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). If the medication becomes discolored, do not use it; obtain a fresh bottle.

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

What happens if I miss a dose?

Since tetrahydrozoline ophthalmic is used when needed, you may not be on a dosing schedule. If you are on a schedule, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.

What should I avoid while taking Optigene 3 (tetrahydrozoline ophthalmic)?

Do not use this medication while wearing contact lenses. Tetrahydrozoline ophthalmic may contain a preservative that can discolor soft contact lenses. Wait at least 15 minutes after using this medicine before putting in your contact lenses.

What other drugs will affect Optigene 3 (tetrahydrozoline ophthalmic)?

It is not likely that other drugs you take orally or inject will have an effect on tetrahydrozoline used in the eyes. But many drugs can interact with each other. Tell each of your healthcare providers about all medicines you use, including prescription and over-the-counter medicines, vitamins, and herbal products.
