[BAHAYA!] Obat Tetes Mata Bila Terminum - FATAL!

Belakangan ini beredar isu tak bertanggungjawab bahwa obat tetes mata dapat digunakan untuk membuat orang diare, pingsan atau malah dapat digunakan sebagai obat perangsang. Apakah anda tahu hal ini sama sekali tidak benar?

Beberapa tetes mata hanya berisi larutan garam steril, yang tidak berbahaya jika tertelan. Namun, tetes mata lainnya dapat berbahaya jika dikonsumsi.
Penting untuk diketahui mengenai obat tetes mata ada yang mengandung Tetrahydrozoline HCL. (misalnya: Vis*ne, In*to)

Tetrahydrozoline HCL merupakan suatu agen vasokonstriktor yang dapat mempengaruhi sistem saraf pusat dan pembuluh darah.

Dalam pengunaannya dimata dapat terlihat mata yang merah - pembuluh darah sedang dalam keadaan vasodilatasi- sehingga beberapa saat setelah diteteskan menjadi tidak merah lagi - pembuluh darah dalam keadaan vasokonstriksi.

Namun apabila dikonsumsi secara oral, tetrahydrozoline mempunyai potensi yang berakibat fatal, terutama untuk anak kecil, penderita penyakit jantung dan orang yang mengkonsumsi MAO inhibitor.

Inilah yang dapat terjadi apabila meminum obat tetes mata yang mengandung Tetrahydrozoline:
1.penurunan suhu tubuh secara extrim
2.penurunan pandangan (pandangan jadi kabur)
3.tekanan darah meningkat, lalu menurun secara ektrim
4.berhalusinasi
5.kesulitan bernafas
6.muntah
7.kejang atau tremor
8.koma
9.penurunan fungsi jantung

Dan secara jelas pada belakang obat tetes mata sudah diperingatkan pengunaannya hanya untuk bagian luar.


Kasus yang pernah terjadi di US::
The active ingredient in Visine eye drops is Tetrahydrozoline HCl 0.05%. Swallowing this substance can result in a number of nasty effects, including:

* Lowering body temperature to dangerous levels
* Making breathing difficult, or even halting it entirely
* Blurring vision
* Causing nausea and vomiting
* Elevating and then dropping blood pressure
* Causing seizures or tremors
* Sending the ingester into a coma

Pfizer's cautions to users of Visine include, "If swallowed, get medical help or contact a Poison Control Center right away." In view of the above list, that advice should not be taken lightly.

Yet if Visine doesn't cause diarrhea, it has done things far more terrible. Drinking it can (and has) caused severe depression of the central nervous system. In 1996, a two-year-old child who ingested at most 2 to 3 mL of Visine eye drops became dangerously lethargic and unresponsive to every stimulus except deep pain. Thanks to prompt medical attention the child recovered, but not before enduring intubation and two days' worth of mechanically-assisted breathing.

Medical literature reports other cases of small children brought to the brink of crisis by ingestion of tiny amounts of over-the-counter eye drops. The danger is real, and parents are well advised to keep eye drops away from children.

Yet it is not only toddlers who risk central nervous system shutdown or other dire results if they swallow Visine. In 1995 an adult customer at a Whole Foods Market (a retail chain of natural and organic foods) had his wheat-grass smoothie spiked with a bottle of Visine by a clerk intent upon playing a practical joke. The victim, Rudy Trabanino of Houston, became violently ill and had to be hospitalized for several days with acute pain and a variety of serious medical problems. The clerk responsible for the act was dismissed, and Whole Foods Market settled out of court with Trabanino for an undisclosed sum after he brought a $1 million suit against the store.

Visine poisoning has also featured in a murder. In 2001, Damien Kawai, a member of the U.S. Air Force, killed his roommate and fellow airman by strangling the young man, then attempted to conceal the crime by slitting the wrists of the corpse to make the death appear to be suicide. Kawai admitted to earlier spiking the roommate's beer with Visine, under the belief this would render the doomed man unconscious. (It actually caused him to vomit and suffer labored breathing).

In May 2002, 19-year-old Damien Kawai was sentenced to life in prison for the 17 November 2001 murder of Charles Eskew.

In June 2006, five Wisconsin high school students trying to pull the Visine prank poured about a quarter of a bottle of the eyedrops into a classmate's water. The victim spent several days in the hospital recovering from reactions to the poisoning that included a dangerously low heart rate and blood pressure. Each of the five "pranksters" pleaded no contest to misdemeanor counts of battery and disorderly conduct and received sentences of 18 months' probation and 60 hours of community service.

Revenge seekers should consider 1 final fact: the act of secreting noxious substances in ingestibles for the purpose of bringing harm to others is called poisoning. It matters not if actual harm results from the attempt — the act itself is enough to land one in the hoosegow.
