Blue Tri
Blue Tri Uses, Dosage, Side Effects, Food Interaction and all others data.
Blue Tri is a selective tissue staining agent (dye) which stains anterior lens capsule of the human crystalline lens. The dye does not penetrate the capsule, permitting visualization of the anterior capsule in contrast to the non-stained lens cortex and inner lens material.

Uses
Blue Tri is used for use as an aid in ophthalmic surgery by staining the anterior capsule of the lens.
Dosage
Blue Tri dosage
The first step to administer Blue Tri is to inject an air bubble into the anterior chamber using a 26 gauge needle. It prevents dilution of dye by the aqueous humor. Then Blue Tri is injected into the anterior lens capsule using a tuberculin syringe. Sufficient staining is achieved as soon as the dye has contracted the capsule. If some area is left unstained, inject one more drop till it gets stained.
Side Effects
- Discoloration of high water content hydrogen intraocular lenses.
- Inadvertent staining of the posterior lens capsule and vitreous face.
- It is generally self limited, lasting up to one week.
Precaution
It is recommended that after injection all excess Blue Tri should be immediately removed from the eye by thorough irrigation of the anterior chamber.
Pregnancy & Breastfeeding use
Pregnancy Category C. There are no adequate and well-controlled studies in pregnant women. Blue Tri should be given to a pregnant woman only if the potential benefit justifies the potential risk to the fetus.
Lactation: It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Blue Tri is administered to a nursing woman.
Contraindication
Blue Tri is contraindicated when a non-hydrated (dry state), hydrophilic acrylic intraocular lens (IOL) is planned to be inserted into the eye because the dye may be absorbed by the IOL and stain the IOL.
Special Warning
Pediatric use: The safety and effectiveness of Blue Tri have been established in pediatric patients. Use of Blue Tri is supported by evidence from an adequate and well controlled study in pediatric patients.
Geriatric use: No overall differences in safety and effectiveness have been observed between elderly and younger patients.
Storage Condition
Store below 30° C and keep away from light.

FAQ
What is Blue Tri used for?
Blue Tri is a diazo dye that has been widely used to color dead tissues or cells selectively.The mechanism of trypan blue staining is based on it being negatively charged and not interacting with cells unless the membrane is damaged.
How safe is Blue Tri?
Blue Tri may cause cancer, genetic defects, and damage fertility, or cause harm to an unborn child.Special precautions should be taken to avoid exposing operators to trypan blue whilst working with and disposing of the dye.
What are the common side effects of Blue Tri?
Common side effects of Blue Tri include: temporary blue coloration of the eye, and staining of implanted lenses.
Is Blue Tri safe during pregnancy?
This drug should be used during pregnancy only if the benefit outweighs the risk to the fetus.
Is Blue Tri safe during breastfeeding?
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when trypan blue is administered to a nursing woman.
How does Blue Tri work?
Blue Tri binds to intracellular proteins and render the cells a blue color.
Why is Blue Tri used in cataract surgery?
Blue Tri is the most frequently used in cataract surgery due to its safety, availability and effectiveness.
Is Blue Tri toxic to humans?
Blue Tri is not toxic, in terms of cell viability, over an exposure time of up to 60s; however, further exposure results in a gradual increase in damage of cultured human trabecular meshwork cells.
