Has anyone used vagisil long term? i've been using it several times a day for several weeks now and am concerned I might be overdosing on it. The doc told me to stop using it but that's impossible. I'd be scratching raw if I stopped and wouldn't be able to function at all. I've a chronic itch that the doc's are still tryiing to figure out what's causing it. I only use small amounts, every 2-3 hours. Is this safe?
