Narlox is used in the following conditions:

  • Opioid overdose reversal: Narlox is commonly used in emergency situations to rapidly reverse the effects of opioid overdose. Opioids, such as heroin or prescription pain medications, can cause respiratory depression, which can be life-threatening. Narlox works by binding to opioid receptors in the brain, blocking the effects of opioids and restoring normal breathing.
  • First aid response: Narlox is often carried by emergency personnel, first responders, and individuals at risk of opioid overdose, such as friends or family members of opioid users. Administering Narlox in a timely manner can be crucial in saving lives in emergency situations.
  • Harm reduction programs: Narlox is a key component of harm reduction programs, which aim to reduce the negative consequences associated with drug use. These programs provide Narlox kits and training to individuals who use opioids, as well as their friends and family members. This empowers them to respond effectively to opioid overdose emergencies.
  • Healthcare settings: Narlox may also be used in healthcare settings, such as hospitals or clinics, where opioid-related emergencies can occur. It is often available in emergency departments and is used in cases where opioid overdose is suspected or confirmed.

This medicine may be recommended for different uses. Approach your physician or pharmacist for more information.

Do not use Narlox in people with the following conditions:

  • Hypersensitivity: Narlox should not be administered to individuals who have a known hypersensitivity or allergic reaction to Narlox or any of its components. Signs of hypersensitivity may include rash, itching, swelling, difficulty breathing, or dizziness. If you have experienced an allergic reaction to Narlox in the past, it is important to inform healthcare professionals.
  • Non-opioid overdose: Narlox is specifically used to reverse the effects of opioid overdose. It does not have any effect on other types of drug overdoses, such as benzodiazepines or stimulants. In cases of non-opioid drug overdose, Narlox will not be effective and alternative treatments should be considered.
  • Neonatal use: Narlox is generally safe for use in neonates born to mothers who have used opioids during pregnancy. However, the dosing and administration of Narlox in neonates should be carefully determined by a healthcare professional with experience in neonatal medicine.

Narlox may have the following side effects:

  • Withdrawal symptoms: Narlox rapidly reverses the effects of opioids, which can lead to the onset of withdrawal symptoms. These symptoms may include sweating, shivering, nausea, vomiting, abdominal cramps, increased heart rate, increased blood pressure, and restlessness. It is important to be aware that these symptoms are temporary and typically resolve within a short period of time.
  • Injection site reactions: Narlox is commonly administered via injection, either intramuscularly or intranasally. Some individuals may experience mild local reactions at the injection site, such as redness, swelling, or pain. These reactions are usually short-lived.
  • Rebound opioid overdose: Narlox’s effects are temporary, and in some cases, the effects of opioids may outlast the effects of Narlox. This can result in a potential “rebound” opioid overdose, where the opioid effects return after the Narlox wears off. It is important to closely monitor individuals who have been administered Narlox and seek further medical attention if necessary.

Keep in mind that your physician has recommended this drug since he or she has known that the advantage to you is more noteworthy than the risk of adverse reactions. Many individuals utilizing this medicine don’t have serious side effects.

A serious allergy to this medication is uncommon. In any case, seek emergency medical help if you see any manifestations of a serious allergic response, including a rash, tingling or swelling particularly of the face or tongue or throat, dizziness or difficulty in breathing.

This is not a complete list of side effects. If you see other effects not recorded above, contact your physician or pharmacist.


Take extra caution in patients with the following medical conditions:

  • Proper training: It is important to receive proper training on how to administer Narlox, whether it is in the form of injection or nasal spray. This will ensure that you know how to use it effectively and safely in an emergency situation.
  • Opioid-dependent individuals: Narlox is safe to use in individuals who are opioid-dependent, including those who are taking prescribed opioids for pain management or those with opioid use disorder. However, it is important to understand that Narlox may precipitate withdrawal symptoms in these individuals. Therefore, it is crucial to have medical support available during and after Narlox administration to manage any potential withdrawal symptoms.
  • Underlying medical conditions: Narlox is generally safe for use in individuals with underlying medical conditions. However, it is important to inform healthcare professionals about any existing medical conditions, such as heart disease or respiratory disorders, as they may require specific considerations during Narlox administration.
  • Pregnancy and breastfeeding: Narlox is generally considered safe for use during pregnancy and while breastfeeding. It is important to consult with a healthcare professional for personalized advice, as they can assess the potential risks and benefits based on individual circumstances.
  • Multiple doses: In some cases, a single dose of Narlox may not be sufficient to reverse the effects of an opioid overdose. Multiple doses or continuous infusion may be required, especially if the individual has taken a long-acting opioid. It is important to follow the guidance of healthcare professionals in these situations.

Prior to taking this medicine, tell your physician or pharmacist if you are allergic to it, or if you have some other hypersensitivities. This drug may contain inert ingredients which can cause unfavorable side effects or different issues. Talk with your pharmacist for more information.


Narlox may interact with the following medicines:

  • Opioid medications: Narlox is specifically used to reverse the effects of opioids. It does not usually interact with other types of medications. In fact, Narlox can be safely administered alongside opioids to counteract their effects.
  • Benzodiazepines and sedatives: While Narlox does not directly interact with benzodiazepines or sedatives, it is important to exercise caution when administering Narlox to individuals who have taken these medications. Benzodiazepines and sedatives can cause respiratory depression, and the sudden reversal of opioid effects with Narlox can potentially lead to a rapid onset of withdrawal symptoms or an increase in anxiety. It is advisable to closely monitor such individuals and seek further medical attention if necessary.
  • Prescription medications and over-the-counter drugs: Narlox generally does not have significant interactions with other prescription medications or over-the-counter drugs. However, it is always important to inform healthcare professionals about all medications being taken, including any herbal supplements or vitamins, to ensure there are no potential interactions.

Inform your physician about the drugs you take including over-the-counter medications, prescribed drugs, supplements and vitamins.

This is not a complete list of drug interactions. Approach your physician or pharmacist for more details.

The effects of certain medications can change if you consume different medications or herbal products simultaneously. This can build your risk for side effects or may cause your drugs not to work effectively. These interactions are conceivable, yet don’t generally happen. Your physician or pharmacist can prevent or oversee interactions by changing how you utilize your prescriptions or by close checking.

While utilizing this drug, don’t start, stop, or change the dose of other medicines you are using without your physician’s advice.

If you suspect an overdose, contact your doctor right away.
