What is allergy tablets do?

Allergy tablets: Most allergy tablets are medications that fall into the category of antihistamines that block the effect of histamine. This treats symptoms such as sneezing, itching, runny nose, etc. Sometimes antihistamines are combined with decongestants to help with stuffy nose. Studies are evaluating "allergy tablets" that may work similar to allergy shots where the tablet contains the pollen, etc. ...Read more

What's the best time of day to take my allergy tablets?

What's the best time of day to take my allergy tablets?

Allergy meds: If your tablet is Allegra and it's non-sedating, you can take it anytime. Ideally, you'd like to take it 30-60 minutes before your allergy exposure, if there's a specific thing you react to. If you take benadryl, (diphenhydramine) best take it at night if it sedates you. If you take sudafed for congestion, avoid taking it at night because it causes insomnia. Prescription sprays, any time you want. Singular --night. ...Read more

What to do if i took 5 allergy tablets the dosage is 1 will i be okay?

What to do if i took 5 allergy tablets the dosage is 1 will i be okay?

Ok but...: As antihistamines have a high safety margin, you may just end up with dry mouth and perhaps drowsiness if you take 5 times the dose in one gulp. The question is why did you take so many at one time? The answer would be different when a decongestant is also present since such a high dose of decongestant can raise your blood pressure and heart rate significantly and potentially causing a stroke. ...Read more

Why do some OTC allergy tablets work for some people but not for others? Which OTC allergy med works best in most people?

Why do some OTC allergy tablets work for some people but not for others?  Which OTC allergy med works best in most people?

Good question!: It is not clear why some persons respond more favorably to some antihistamines and not others. There are theories, but still not completely known. In my experience zyrtec (cetirizine) works very well for most people. Also, the approved doses of antihistamines were determined based on the minimal effective dose for the majority of people. Some persons may just need a higher dose! ...Read more

What other allergy tablets can I take with fexofenadine 180 mg?

What other allergy tablets can I take with fexofenadine 180 mg?

Allergy Meds: Hello, you could add a nasal saline spray to assist your medical plan for allergy. A rx for an intranasal steroid spray and/or singulair (montelukast) may be added to your therapy. These medications must be prescribed by your doctor. An additional dose of fexofenadine is sometimes effective for worsening symptoms. I recommend reviewing this option with your doctor. ...Read more

What is allergy tablets do to stop my rash?

What is allergy tablets do to stop my rash?

Depends: There are different types of allergy tablets. Antihistamines (claritin, zyrtec, allegra) block the effects of histamine so they can decrease itching and redness. The tab singulair (montelukast) is a leukotriene receptor blocker which blocks the effects of leukotrienes--this can also decrease itching and redness. Oral steroid tablets are very potent and have side effects-they decrease inflammation. ...Read more

After how long should we take the allergy tablets after consumption of alcohol?

After how long should we take the allergy tablets after consumption of alcohol?

Varies, with meds!: Good morning, how long you should wait after alcohol depends on the type of antihistamine. For non-sedating antihistamines such as Claritin and allegra, it there should be no additive sedative effect with the combination, while Benadryl (diphenhydramine) and hydroxyzine, you need to be fearful of the added sedation due to alcohol intake and wait at least four hours for the alcohol level to come down. ...Read more

Think was given a vyvanse (lisdexamfetamine) instead of an allergy tablet . How long does it take to get it out of your system if you have never taken it before?

  Think was given a vyvanse (lisdexamfetamine) instead of an allergy tablet .  How long does it take to  get it out of your system if you have never  taken it before?

Not long: I would expect most of the drug to be out of the body after 24 hrs. As for whether one may still detect very minute traces of the drug after that period, it is hard to tell but certainly not more than a week at the maximum. ...Read more

Does piriton allergy tablets cause breathing problems? I've been experiencing breathing difficulties since i've taken them.

No : Piriton is the uk version of chlorpheniramine, an antihistamine which is safe and has been available over the counter in the usa for decades. It can make your secretions dry and thick, so if you has asthma, it could make it worse, but that's true of all antihistamines, not just piriton. If you're short of breath, please seek medical help! ...Read more
