8Vitamin B11 Toxicity
While vitamin B11 toxicity is quite rare, it would happen after a topical application. To lower the risk, you should:
– Avoid applying it under a plastic wrap or air-tight dressings
– Avoid using it for an extended period
– Avoid applying it to a large body area
Stop applying vitamin B11 immediately and visit your healthcare provider as soon as you notice one of these signs: hearing loss, buzzing or ringing sounds in the ears, confusion, headache, nausea, vomiting, hyperpnea, or diarrhea. [8]
