Modalert 200mg is a good drug for encouraging alertness, not everyone can use it. There is insufficient evidence to support Modalert's safety during these times. Unless a doctor certifies that the advantages exceed the hazards, it should be avoided. Because modalert might raise blood pressure and heart rate, it is not recommended for those who have heart issues such arrhythmias, angina, or uncontrolled hypertension. Modalert might worsen psychiatric symptoms, such as agitation or mania, thus those with disorders like anxiety, depression, or psychosis should stay away from it. Modalert's metabolism may be impacted by reduced organ function, which might raise the possibility of adverse effects. Modafinil should not be used by anybody who has a known allergy to the drug or any of its constituents. Rashes, edema, and more serious symptoms like Stevens-Johnson syndrome are examples of allergic responses.
