About Verfen Injection

FENTANYL belongs to a class of drugs known as 'opioid analgesics,' primarily used to relieve pain. It is used to treat breakthrough pain (sudden episodes of pain occurring despite treatment with pain medication) in cancer patients. Pain can be temporary (acute) or long-lasting (chronic) in nature. Acute pain is caused by damage to the tissues of the muscle, bone, or other organs for a short time. Chronic pain lasts for a long duration and is caused due to pathologies like nerve damage and osteoarthritis.
