Next Steps & Follow-up

After a person has recovered from a benzo overdose, it is important for them to seek help. This can include screening for intentional benzo overdose as well as medical detox and rehab. Doctors and loved ones need to be on the lookout for additional risks, like suicidal ideation and relapse risk.

Suicidal Intentions

Benzos canincrease a person’s risk of suicide, especially if they have a history of anxiety and take benzos as their only treatment. Many instances of suicide by benzo overdose have occurred, especially inolder adults. For these reasons, doctors should closely monitor a person with a history of mental health problems who is on a benzo.

Relapse & Tolerance Considerations

When a person has been taking a benzo for a long time, their body gets used to the dose, leading to tolerance. When a person is tolerant to a drug, they require higher doses to obtain the same effects. When a person stops the drug, their tolerance decreases.

This means that if a person stops taking the benzo and then relapses, a dose they would have previously been able to take without a problem now puts them at risk of overdose. The risk is especially pronounced in those who take relatively high benzo doses and those who use multiple substances.
