Taking Klabax and Telfexo together may cause and worsen the side effects of fexofenadine, the ingredient in Telfexo. The most common are: headaches, drowsiness, nausea, palpitations. If the medications have been prescribed by different doctors, a consultation is advisable to determine whether the medications can be used concomitantly and, if so, whether there is a need to change the dosage.

It is always worth informing your doctor about all medications you are taking, especially those taken chronically. This will allow for the selection of the appropriate therapy without the risk of interactions between the agents used.
