Is there any other antihistamines that have as strong of or stronger anti allergic properties than benadryl (diphenhydramine)?
Depressants: Most general anesthetic agents (both those given intravenously and those that are inhaled) are strong respiratory depressants because they decrease the body's urge to breathe. Specifically, they eliminate the ventilatory drive in response to hypoxia (low oxygen) and reduce the ventilatory drive in response to hypercarbia (high carbon dioxide). There are, of course, exceptions. ...Read more
Nausea treatment: Phenergan (promethazine) is a pretty good medication for symptomatic treatment of nausea. Meclizine seems to work better in motion sickness. If you are still symptomatic with those medications, you should be seen and evaluated by your physician to find out what causes it. Many serious health problems can cause nausea and vomitting. ...Read more
Can i take expectorant+antihistamine combi cough syrup? aren't the actions contradictory? expectorant increasing & anti-histamine drying secretions?
Need alternative to zirtec for allergy-induced asthma. Allegra and Benadryl (diphenhydramine) don't work, nor albuterol asthma inhalars. Claritin gives me nasal pain.
Allergic help: You will definitely need to speak with your physician about this. Other alternatives include the short acting chlorphenamine (chlortrimetron), sold over the counter. There are prescription medications - xyzal, singulair, xopenex, (levalbuterol) Flonase and more. Ultimately - make sure you speak with your physician about this, since the medications you have tried so far are not providing relief for you. ...Read moreSee 2 more doctor answers

Is pseudoephedrine safe for asthma as well as loratadine both in Claritin D because I know Benadryl (diphenhydramine) as an antihistamine is contraindicated ?
No longer used in US: This medication is not in the U.S. but remains throughout the rest of the world as an analgesic mostly associated with postoperative or perioperative pain relief. It comes as an IV so is considered a resonably potent type of drug for pain relief though less than narcotics since it is not a narcotic. I would agree that it would be considered to have more analgesic power than straight paracetamol ...Read more
Yes: Claritin is a second generation antihistamine which causes much less drowsiness than first generation antihistamine, like benadryl (diphenhydramine). The number of people who feel drowsy on Claritin is so low that it is labeled "non-drowsy". But each of us is unique. I have plenty of patients who feel drowsy on claritin, especially petite women. ...Read moreSee 1 more doctor answer
Yes: Claritin (loratadine) and zyrtec are both oral antihistamine agents that block the effects of histamine on what is called the h1 receptor. By doing this, they reduce the release of histamine, a substance that causes itching, runny nose, and sneezing. Zyrtec blocks the receptor a bit better, but the clinical effect of the medications is roughly the same. Zyrtec may cause some drowsiness, but may last longer. ...Read moreSee 1 more doctor answer
