Dangers of long-term Phenergan usage?

[nuclearpowerpants]

Hi, I have severe allergies and the resulting nasal congestion and asthma makes it very hard for me to sleep at night. I have tried dozens of sedatives and sleeping drugs (as well as the whole meditation, therapy angle) and surprisingly, the most effective solution has been 20 - 25mg of phenergan each night. My immunologist expressed concern about me taking phenergan every night, but I have been doing so for about 3 months now will no ill effects.
Does anyone know if there is a danger of taking this strong dose of Phenergan regularly for a long period of time?
Thanks!

Hi
Welcome to the forum!
Long term use of Phenargan can cause drowsiness, blurred vision, dizziness; confusion, disorientation, incoordination, fatigue, insomnia (later on), tremors, convulsive seizures, excitation, mania, hallucination, increase in blood pressure, heart rate, and decrease in the blood cell count. After use for some time, this drug will start causing nasal stuffiness and asthma like symptoms, and your whole purpose of taking the drug would be lost.
Please go through proper medication for your condition. There are many other safer drugs to take care of asthma and nasal congestion. Please take drugs as advised by your doctor. Wearing masks specially designed to filter allergens will help you in a big way. Talk to your specialist about this.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
