It was a nose spray Dr Marinkovich makes up at his clinic in Redwood City, Ca. He is one of the best mold doctors in the country. 85% of his patients are mold victims from around the country. It was 15% Nizoral and the rest Chromolyn Sodium. It's one of the mildest antifungals. It worked well for me. Once it kicked the mold in the ass, I have moved over to natural remedies like chlorophllin. At one point he prescribed me Nizoral in tablet form, which I crushed 50 mg into powder and mixed with 2ml of Chromolyn Sodium Inhalation Solution. Then I used my nebulizer to deep breath it into my lungs. Within an hour I was coughing little black goober mold colonies up out of my lungs.
