Niphanoid

Tetracaine is a local anesthetic (numbing medicine). It works by blocking nerve signals in your body.

Niphanoid is given as an epidural injection into the spinal column to produce numbness during labor, surgery, or certain medical procedures.

Tetracaine may also be used for purposes not listed in this medication guide.

Tetracaine is injected with a needle into an area of your middle or lower back, close to your spine. You will get this injection in a hospital.

While you are receiving Niphanoid, your breathing, blood pressure, oxygen levels, and other vital signs will be monitored closely.

Spinal numbing medicines can have long-lasting effects on some body processes, including sexual function, bowel or bladder control, and movement or feeling in your legs or feet. Discuss these effects with your doctor.

You should not receive Niphanoid if you are allergic to Niphanoid or any other numbing medicine.

You should not receive this medicine if you are allergic to Niphanoid or any other type of numbing medicine.

Tell your doctor if you have ever had:

• high blood pressure;
• heart disease, heart rhythm disorder;
• any type of infection;
• hereditary angioedema or allergic reactions; or
• a disease or medical condition that affects your brain or spinal cord.

Unless you are receiving this medicine during labor and delivery, tell your doctor if you are pregnant.

It may not be safe to breast-feed while using this medicine. Ask your doctor about any risk.

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

Tell your caregiver right away if you have:

• a light-headed feeling, like you might pass out;
• tremors, severe drowsiness;
• weak or shallow breathing;
• severe headache, neck stiffness, increased sensitivity to light; or
• numbness, tingling, burning pain, or severe shooting pains anywhere in your body.

Common side effects of Niphanoid may include:

• feeling nervous or excited;
• dizziness, drowsiness;
• chills;
• headache;
• blurred vision;
• nausea, vomiting; or
• ringing in your ears.

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 FDA at 1-800-FDA-1088.

Since tetracaine is given as needed before a surgery or other medical procedure, you probably will not follow a dosing schedule.

Since Niphanoid is provided by a healthcare professional in a medical setting, an overdose is unlikely to happen.

Follow your doctor's instructions about any limits on food, drinks, or activities.

Tell your doctor about all your other medicines, especially:

• sulfa drugs (Bactrim, Septra, Sulfatrim, SMX-TMP or SMZ-TMP, and others).

This list does not include everything. Other drugs may impact tetracaine, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are mentioned here.
