If someone was given Monit GTN 6.4 mg instead of 2.6 mg for more than 10 days and now feels weak, heavy headed, and dizzy, what should be done? Will he get better if switched back to 2.6 mg?
Monit GTN is a nitrate, and taking a higher dose than needed can commonly cause weakness, headache, heaviness in the head, and dizziness due to low blood pressure. These symptoms are dose-related and usually improve when the dose is reduced. If the dose is corrected back to 2.6 mg as prescribed, the person often feels better gradually. However, blood pressure should be checked, and a doctor should be informed to rule out ongoing hypotension and to decide whether dose adjustment or temporary stoppage is needed. Do not continue or change the dose without medical advice, especially if dizziness persists or worsens.
