These are the most common mistakes when taking antihistamines

We are not taking the right medicine, not at the prescribed dose or for too short a time. We now turn to the common problems associated with taking antihistamines.

We are not taking the good active ingredient

Antihistamines can be used to relieve allergic symptoms. A wide variety of formulations are available, many of which can be obtained by patients without a prescription. However, it should be noted that these products differ not only in their packaging but also in their active ingredient. Thus, one that works well for nosebleeds, itchy noses, is not the best choice for itchy allergic skin symptoms.

We don’t pay attention to drug interactions

“A For the full list of all side effects reported with this medicine, see the Package Leaflet. Always consult this medicine before prescribing or, in the case of over-the-counter medicines.” – says dr. Monika Augusztinovicz otolaryngologist, allergist, doctor of the Buda Allergy Center.

Some medicines, such as antidepressants and certain antifungal medicines, may interact with antihistamines. Therefore, always inform your doctor about other medicines you take regularly, because otherwise the medicines you take together may change the breakdown of the other medicine, their absorption and effects may change, or the effect may be prolonged.

We are taking less than prescribed

A common pitfall of taking antihistamines is that if taking the drug, for example, has a hypnotic effect, patients tend to reduce the prescribed amount. Thus, although their performance will improve, due to the reduced amount of active ingredient, their allergic symptoms will intensify again.

Avoid side effects

Indeed, first-generation antihistamines are more likely to cause side effects such as dry mouth, double vision, or urinary retention. However, newer formulations have significantly fewer side effects. However, concomitant use of alcohol should be considered because the mild somnolence side effect of certain types of second-generation antihistamines may be increased when consumed with alcohol.

We are taking it for too short

The duration of taking antihistamines always depends on the cause. Symptoms of pollen allergy can be taken throughout the pollen season. When used in the long run, they are more effective than when used only at high pollen concentrations. The effect of the drugs can be felt as early as half an hour after ingestion, but it usually takes 1-2 hours to get the best effect.

It is important to keep in mind that allergic symptoms may not be eliminated by the antihistamine alone. In most cases, it is used in combination, and other medications may be needed based on personalized symptoms.
