Modalert 200 and other modafinil products are typically safe, however respiratory issues might occur in rare circumstances. Modafinil may cause shortness of breath, chest tightness, or trouble breathing in rare cases. If these symptoms develop, get medical treatment immediately since they may signal a serious allergic response or breathing difficulties. Modafinil should be used cautiously and under medical supervision by those with respiratory disorders. Before using modafinil or any other medicine, see a doctor about any concerns or pre-existing problems.
