Global Patient Feedback for Claritin (Loratadine) ( Post a comment )
Question/Comment:
I take loratidine year round with no apparent side effects. I do have a real problem with inner-ear infections,(which can cause vertigo) so I take guifenisen as well to thin the mucus. Be sure to take evening dose early, as it can keep you awake. This combination has worked for me for years!! Be sure you check with your Dr. first, because guifenisen can increase heart rate if taken in large doses. I had some BAD bouts of vertigo a couple of years ago, went through all the usual tests & ENT stuff. Was diagnosed with Menere's disease. Turned out not to be so, went to chiropractor & turned out I had a pinched nerve in my neck. It took about three weeks of treatments, but it worked!! I get a "tune up" once a year and if I feel it coming on. I have fibromyalgia, so am prone to muscle & nerve problems.

Question/Comment:
I had a severe case of vertigo. The ENT physician performed a hearing test, gave me exercises and said come back in six weeks. A few days later, my hairdresser advised me to take one Claritin (not D) tablet daily plus motion sickness pills; vertigo cleared up in two days and I discontinued the motion sickness pills. At my six-week visit to the ENT, he recommended that I take Claritin and motion sickness pills. I've continued the Claritin.

Answer/Reply:
Fluid in the ear and sinus areas can cause vertigo. If Claritin clears it up... well then why take additional medicine that is not needed. Also be aware that it may be seasonal for you. You may not even need the Claritin all year... Good Luck.

Answer/Reply:
The drug in the motion sickness pills acts as a decongestant as well, so if your vertigo was due to allergies or sinuses being clogged, that may be why it helped. I, too, have allergies and occasionally have bouts with vertigo. Whether my vertigo is genetically linked or allergies or both, an OTC motion sickness pill or two always seems to help. I keep them around for flare-ups of the vertigo, but do not take them daily.

Answer/Reply:
I don't have MVP but I have hyperthyroidism and it does not affect my heart rate. I take it daily 9 months out of the year here in NorthEast TX. If your Doctor knows your conditions and prescribed it...it is probably alright. I have not heard of anyone having tacycardia with it or I wouldn't be taking it either. I'm an RN by education and I did read the complete insert.

I also suffer from tachycardiaand have found that the only med that does NOT get my heart racing is loratadine or claritin. A blessing during allergy season which here in Portland, OR is nearly 8 months a year!

Answer/Reply:
Your doctor should be well aware of your medical history and should not prescribe anything that will cause you trouble; HOWEVER, mistakes are made all the time. You need to talk with the pharmacist before filling the prescription. He or she will be able to advise you regarding any side effects. If you are given the go ahead to take the medication, I would suggest going to Sam's Club and buy the Loratadine there. At my club it is less than $13.00 for 300 tablets. That's nearly a year's supply if you take it daily!

Answer/Reply:
My mother has MVP and uses loratadine (generic Claritin) twice a day. She has no complications from it. I have an arrythmia (sp?) and also take loratadine (10mg, btw) twice daily. It has not increased or interrupted my heart rate at all. I've been taking it for about 10 years. Recently (past 6 months), I started taking Zyrtec at the direction of my dermatologist. I have pretty severe allergies and he swears this is still better than Claritin. Just food for thought. I think I still like Claritin better.
