Dosage of Prednizone was only 40 mg once a day for 3 days, and tappered off everly 3 days down to one tablet. This was prescribed for needed LUNG EXPANSION DUE TO BREATHING PROBLEMS. The following side effects manifested; I felt like superwomen the second day, thought this stuff is magic...however, by the third morning, Thrush infection appeared in my throat and mouth, had extreme, sharp pains when swallowing, dizziness, general weakness from the Thrush like early flu - this Thrush looks like white spots or white coating & SPREADS WITHOUT THE AIDE OF anti-fungal mouth tablet to irradicate. IMMUNE SYSTEMS WEAKENED BY PREDNIZONE. Insomnia also experienced to the point of only three hrs. sleep a night. I stopped taking the predizone immediately and continued the anti-fungal mouth table of clotrimazole (10 mg) to clear up the Thrush infection and finally got back to normal. No more for me!!!!
