Zaditor Reviews

For Conjunctivitis, Allergic "I had continuous allergic conjunctivitis, I thought it was mascara... kept switching brands and types of mascara. After a year of three month intervals of conjuctivitis... Went to eye doctor, gave me Pazeo (olopatadine hydrochloride ophthalmic solution 0.2% ) . He said I just started having bad reactions to the contacts themselves rubbing up against my eyelids. That Pazeo That stuff worked instantly, didn't wake up with crusty or swollen eyes. He told me after the Pazeo drops continue with 2x day Zatidor drops. OMG they were awful. As soon as they went in my eyes were burning.. The intense burning sensation did subside after 5 min. But it was awful burning. . At 30 min still stinging. I had scratchy feeling eyeballs ( they were totally dried out) the rest of the day. I had awful taste in my mouth also. Tried it again in the EVENING. same thing.. Next morning I woke up and my eyes were really puffy like above my eyes I had the puffy upper eyelids setting over my eyeball."


For Conjunctivitis, Allergic "Very helpful. I am mostly allergic to tree pollen (oak, birch). Stings a bit and causes lots of tears after application, but it goes away within minutes. Took a day or so to become really effective - I started at the peak of the allergy season. I feel like a new person!"


For Conjunctivitis, Allergic "I woke up today with severe stinging in my eyes and tears rolling down my face. I knew it was allergies, but I rarely get allergy eyes this bad. In fact, I've only had allergy eyes twice in the past 10 years (and today was the second occurrence). Dad went out and bought Zaditor for me (after I researched eye drops to buy, which was after I flushed my eyes with a lubricant drop), and I put them in, and within 5 minutes, my eyes were perfect! I started noticing stinging again about 10:40 PM tonight and put them in again, and now my eyes are great again. I love this eye drop! I did not feel any burning or stinging or any other side effects when using these drops. This was the first day of using any allergy eye drop, so I didn't know what to expect."


For Conjunctivitis, Allergic "My eyes were so itchy and uncomfortable! I tried Zaditor and immediately felt relief. After several days' use, dosing once in the morning and once at night, my eyes feel normal again. Even though Zaditor only contains an antihistamine (unlike Visine Allergy), my eyes are no longer red and scratchy feeling. It's so nice to find something OTC that works!"


For Conjunctivitis, Allergic "Started using it first day it helped had a little burning, second day eyes were red eye lids upper and lower itched, burned, redness and swelling around both eyes. Runny nose along with a cough came on day 3. Went to eye doctor and told to stop using, he prescribed another drop that had steroid in it."


For Conjunctivitis, Allergic "I developed red, swollen eyes as a result of using Zaditor, an apparent allergic reaction to its ingredients. I later tried a similar and cheaper store brand, and had the very same reaction. Comparing both "active ingredients" both listed Ketotifin Fumarate as such. I do not react to Opcon which does not contain this ingredient (but my store stopped carrying it)."


For Conjunctivitis, Allergic "Zaditor works extremely well for me. Immediately stops my eyes from itching. I’ve been using it for years even before it became approved the OTC. LOVE THE STUFF and take it with me ABSOLUTELY EVERYWHERE!! A bottle lasts a long time, too."


For Conjunctivitis, Allergic "Eye doc recommended. Have used on/off for two years. No issues or negative effects. Works pretty well for me wirh relieving itching from allergies, particularly cat dander. As a pet sitter who is allergic to cats I’m glad to have found zaditor!"


For Conjunctivitis, Allergic "Works when my eyes aren't too bad, but when my lids are swollen, it stings and doesn't work. I got Bepreve instead and that helps without stinging."
