Precautions

Drug information provided by: IBM Micromedex

The effects of the opioid medicine may last longer than the effects of the naloxone. This means the breathing problems and sleepiness could come back. Always call for emergency help after the first dose of naloxone.

Severe opioid withdrawal symptoms may happen suddenly after receiving this medicine. These include body aches, a fever, sweating, runny nose, sneezing, goose bumps, yawning, weakness, shivering or trembling, nervousness, restlessness or irritability, diarrhea, nausea or vomiting, stomach cramps, fast heartbeat, and increased blood pressure.

Some types of opioid medications (eg, buprenorphine) may require larger or repeat doses of naloxone to reverse the opioid effects.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
