For Vertigo "First, let me say that from the moment I was prescribed meclizine for vertigo, I didn’t feel it was necessary. I had a few short dizzy spells and brought it up to my doctor. He put me on 25 mg of meclizine, three times a day. Although weary, I took it as prescribed for 4 days before I had to stop. I felt such a heavy mental fog, I must have fallen asleep about 3-5 times each day that I took it, and I was completely spaced out. I felt absolutely exhausted from the minute I woke up. On the last day I took it, I had fallen asleep at 8 pm the night before, woke up at 7:30 am, went back to bed at 10 am, and didn’t get up until I had to at 5:30 pm because I had to go to work. I felt numb and “shut off.” The side effects were far worse than the brief dizzy spells I experienced."

For Vertigo "I am 47 going to be 48 this month. I've always been healthy with no issues. This past month/year I was at work and felt dizzy, sat down and threw up, and then passed out. They called EMTs for me. Rushed to the ER and was told possible extreme vertigo. I went to my PCP and she concurred and put me on 12.5 mg Meclizine 3 times a day. It's been 2 days and I feel like I'm drunk. I am having a bad earache and can't focus well. I drove to work fine, once I sat still for 30-45 minutes, the feeling of dizziness came back. I can't walk more than a few feet without looking and feeling drunk. I've been on Meclizine for 4-5 days now. I cannot live feeling drunk all day... Is there any other meds that don't do this? Thank you for your advice."

For Vertigo "I went to the ER for extreme vertigo a little over a week ago. This was drop me to my knees, room spinning, vomiting vertigo. The ER first gave me Valium, but the results weren't that great, so they then gave me meclizine and wrote me an RX for some to have at home. It didn't work that great the first day because my symptoms were so extreme, but over time, everything is starting to go back to normal. It's just going very slowly. My balance is back, and I'm not dizzy anymore, but I still feel foggy. I'm weaning myself off and only taking 1/2 a pill at night. When taking the 3 pills a day, it was very tiring and loopy, and I couldn't remember anything. Also, driving is out of the question! I felt like I was drunk."

For Vertigo "I have been taking this medicine now for 3 days, however, I still suffer from the dizziness and have noticed it makes me sleepy. I don't know if this is a side effect or not, but I have been very irritable since starting it. I'm not going to be able to take it due to working with clients all day and on the computer. My mind is so foggy."

For Vertigo "I have acute attacks of vertigo and always keep this medication on hand. I have found that it works better if you take it before the episode occurs. For example, I always have an attack when I go swimming, but if I take it before I go to the beach, I am fine. If I wait until the attack occurs, it doesn't work as well. That being said, the drug will sometimes cause heart palpitations, gives me a headache, and causes a strange mental fog that makes it hard to concentrate or carry on a conversation with anyone, it also makes me irritable."

For Motion Sickness "I took it 3 hours before bed. I slept for 10 hours, which is way longer than normal, and I felt exhausted when I woke up. I also had mental fog for the next 4 hours after I woke up. I then went back to bed for 3 hours. I woke up exhausted again and with mental fog. I literally just spaced out/nodded off for 3 min while writing this. So hazy. Other people made similar comments. It seems to hit a certain group of people like this. It seems to have dried out my inner ear like the doctor wanted, though."
