Uses for Tri-Nasal

Triamcinolone nasal spray is used to treat an itchy or runny nose, sneezing, and other symptoms caused by seasonal and perennial hay fever (allergic rhinitis).

Triamcinolone is a steroid (cortisone-like medicine). It works by stopping the inflammation that happens during allergic reactions.

Precautions while using Tri-Nasal

It is very important that your doctor checks the progress of you or your child during regular visits. This will help your doctor see if the medicine is working well and decide if you or your child should keep using it.

If your or your child's symptoms do not improve within 3 weeks or if they get worse, check with your doctor.

This medicine may raise your risk of having some unwanted effects in the nose. Check with your doctor right away if you or your child have bloody mucus, sores inside the nose, unexplained nosebleeds, or a whistling sound when breathing while using this medicine.

This medicine may cause thrush (a type of fungus infection) in the nose or throat. Tell your doctor right away if you or your child have white patches in the throat or pain when eating or swallowing.

Check with your doctor immediately if you have changes in vision, such as blurred vision, difficulty reading, or eye pain during or after treatment. Your doctor may want your eyes checked by an eye doctor.

You may get infections more easily while using this medicine. Avoid being around people who are sick or have infections such as chickenpox or measles, especially if you have never had these infections or been immunized. This is especially important for children. Tell your doctor right away if you think you have been exposed to chickenpox or measles.

This medicine may increase your risk of having an adrenal gland that is less active than normal. The adrenal gland makes steroids for your body. This is more likely for people who use steroids for a long time or at high doses. Check with your doctor right away if you or your child have any of the following symptoms: darkening of the skin, diarrhea, dizziness, fainting, loss of appetite, mental depression, nausea, skin rash, unusual tiredness or weakness, or vomiting.

This medicine may cause children to grow more slowly than normal. This could result in a child not gaining weight or getting taller. Talk with your doctor if you think your child is not growing properly or if you have any questions about this.
