Please can someone tell me how many mg of oxybutynin does it take to overdose?

Here are some ...: Its standard dose for adults is 5 mg orally 3 times daily, occasionally, may be up to 10 mg 3 times under close supervision. As to how much an individual can take, it's something to do individual age and health state, especially with liver function; these are similar to the concern of using other drugs. So, following recommended dose is the rule for all drug use. If needed to up or down dose, ask.
