No, Eptoin does not cause TB infection.
Isoniazid is a drug used to treat TB infection. Seizures are a potential side effect. So, TB patients may sometimes experience seizures while taking isoniazid. These are completely reversible with medical intervention, which may involve using Eptoin for treating seizures. People may confuse the conditions and presume that TB, seizures, and eptoin usage are related. Whereas, seizures are a potential side effect of the TB treatment with isoniazid.
