Chlorpheniramine for Allergic Rhinitis "Have returned repeatedly to Chlor-Trimeton after taking Zyrtec or Claritin off and on. I get relief for hay fever symptoms without drowsiness, and the cost is lower. I feel sleepy on the other two meds, and the 24-hour dose is not consistent over that period of time. My hay fever is not a severe case, with a runny nose, itchy eyes, and sneezing from mid-March to May, seemingly getting less with age. I'm 69. Have tried the 12-hour dose and find it works consistently for me, but I prefer the 4-hour tablet."

For Allergic Rhinitis "Chlorpheniramine is a very effective drug. I tried all the antihistamines and medicines like cetirizine, loratadine, fexofenadine, etc. I spent a lot of money, but just chlorpheniramine worked for me, and chlorpheniramine is very cheap! A few minutes after taking this, I get complete relief, and my allergies have gone, especially eye allergy. Chlorpheniramine has 2 side effects for me: 1 - makes me very sleepy, 2 - need to take this every 4 hours, at least 4 times a day."

For Allergic Rhinitis "These little yellow pills work for regular seasonal allergies better than any other. I take only if needed and seldom more than 1 in a 24-hour period. They have never made me sleepy, but I usually take at least 2 Anacins every day-headache. I gave my teenage granddaughter one, and they work better for her than prescription meds, but my daughter flipped out when she took one and it made her very sleepy. I have been ordered to never give her children, my precious grandchildren, anything."

For Allergic Rhinitis "I love this allergy medicine! It works like a charm, and it rarely makes me sleepy, unlike Benadryl. Once in a while it's not effective, but this doesn't happen often. I agree with previous reviewers-it's sometimes hard to find on the shelf."

For Allergic Reactions "I took only one tablet, then, after 2 hours, I started to feel dizzy, sleepy, numb face, my heartbeat started to go faster, difficulty in coordinating my hands, and uncontrollable shaking of my body, headache, muscle twitching, and muscle weakness! After 24 hours, I am still feeling dizzy and have a numb face sensation!"
