In allergy season, many times we are forced to use the first-aid kit to avoid some of the most bothersome symptoms. In this case, we will most likely opt for antihistamines, a family of drugs that reduce the intensity of allergic reactions and that in many cases can be obtained without the need for a prescription.
What side effects can they have?
The group of antihistamines, to which drugs such as ebastine or loratadine belong, it is usually a very safe one. They are a good option to combat signs such as congestion, runny nose, sneezing, itching, or allergic conjunctivitis.
However, and as with any medication, antihistamines can cause a number of adverse reactions of variable severity and frequency that should always be taken into account, to stop the consumption of the compound or seek medical help if necessary.
According to the US National Library of Medicine, antihistamines may cause certain vision changes (such as blurred vision), decreased appetite, dizziness, drowsiness, dry mouth, and mood changes (feeling nervous, excited, or irritable).
In general, these side effects are not serious and disappear with the cessation of taking the drug. If they persist, are severe or are accompanied by other worrisome symptoms, it is necessary to see an emergency doctor.
In addition, it is convenient take extra precautions in certain particular cases. For example, adults should be aware of how antihistamines affect them before driving under their influence or operating heavy machinery (especially since drowsiness is an especially common side effect of these drugs). Also, their use in pregnant women should be consulted with a specialist, and when they are used recurrently in young children they should be monitored so that they do not affect their ability to learn.
Finally, the people with certain pathologies (diabetes, enlarged prostate, epilepsy, heart disease, glaucoma, or overactive thyroid) should consult their doctor before using these drugs.
