• You are planning or want to plan a pregnancy.
• You have an upcoming surgery.
• Avoid taking hot baths, lying in the sun, or using heat sources.
• Avoid strenuous exercise while taking this medicine, since it may result in an overdose due to an increase in body temperature.
• Avoid in debilitated patients.
• Do not consume if you are experiencing minor pain.
• Inform your doctor about your current prescriptions, over-the-counter items (e.g. vitamins, herbal supplements, etc. ), allergies, pre-existing disorders, and current health problems before using Verfen Injection.

• Only people who have been specifically trained in the use of intravenous anaesthetics and the management of the respiratory effects of powerful opioids should deliver Verfen Injection. The following points are kept in mind before administering Verfen injection:
• Make sure you have an opioid antagonist on hand, as well as resuscitation and intubation equipment and oxygen.
• Individualise dosage based on age, body weight, physical status, underlying pathological condition, other medications used, kind of anaesthesia utilised, and surgical procedure.
• Keep an eye on vital indicators on a regular basis.
• When the solution and container allow, visually inspect parenteral medication products for particulate matter and discolouration prior to delivery.

Overdose

• Respiratory depression, drowsiness progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and in some cases, pulmonary oedema, bradycardia (reduced heart rate), hypotension (reduced blood pressure), partial or complete airway obstruction, atypical snoring and death can all be signs of an acute overdose with Verfen Injection.
• In the event of an overdose, the reestablishment of a patent and protected airway, as well as the initiation of aided or regulated ventilation, are the top objectives. Other supportive measures (such as oxygen and vasopressors) should be used as needed to manage circulatory shock and pulmonary oedema. Advanced life-support techniques will be required in the event of cardiac arrest or arrhythmias (altered heart rate).
• Naloxone or nalmefene, opioid antagonists, are particular antidotes to respiratory depression caused by opioid overdose. Administer an opioid antagonist if you have clinically significant respiratory or circulatory depression due to fentanyl overdose.
