The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. The patient may receive:

• Breathing support
• Fluids by IV
• Laxative
• Medicine, called a narcotic antagonist, to counteract the effects of the heroin (multiple doses, if needed)

If an antidote can be given, recovery from an acute overdose occurs within 24-48 hours.

Because heroin is commonly injected into a vein, there are health concerns related to sharing contaminated needles. Sharing contaminated needles can lead to hepatitis, HIV infection, and AIDs.
