| Italics | For the most part, italics indicate an FDA comment such as:
Additions and/or revisions underlined These italics usually appear at the beginning of the section. In some cases, italics may be an inherent part of the label, and will most often appear in the body of the section. |
| Underlines | Any text that is underlined indicates text that has been added or revised. There are exceptions where underlining occurs in a section subtitle or heading. This is the case when there is just one word underlined in the body of the text. |
Sections
| BW | Box Warning |
| WP | Warnings and Precautions all in one section (PLR-format) Warnings as one section (pre-PLR format) Precautions as one section (pre-PLR format) |
| AR | Adverse Reactions (in pre-PLR format, this may be a subheading under precautions). |

| USP | Use in Specific Populations (Inclusive on one or more of the following: Pregnancy; Lactation (PLLR- format); Nursing Mothers (pre-PLLR format); Females and Males of Reproductive Potential (PLLR format only); Pediatric Use, Geriatric Use, Renal Impairment, Hepatic Impairment, Sex, Race (these last six may be a subheading of precautions if label in pre-PLLR format. |
| PCI/PI/MG | Patient Counseling Information (PLR format only) - summarizes the information that a health care provider should convey to a patient (or caregiver when applicable) when a counseling discussion is taking place (e.g., a physician prescribing a drug during an office visit, a nurse providing discharge instructions at a hospital, or a pharmacist conveying information at a pharmacy). Patient Information - FDA approved patient labeling. Medication Guide - paper handouts that come with many prescription medicines. The guides address issues that are specific to particular drugs and drug classes, and they contain FDA-approved information that can help patients avoid serious adverse events. |
Only NDAs and CDER regulated BLAs are included in this database. ANDAs are not included.
Applications that remain active, even if the product has been discontinued, undergo safety-related labeling changes.
QUELICIN (NDA-008845)
(SUCCINYLCHOLINE CHLORIDE)
Safety-related Labeling Changes Approved by FDA Center for Drug Evaluation and Research (CDER)
11/01/2022 (SUPPL-80)
4 Contraindications
Additions and/or revisions underlined
QUELICIN is contraindicated:
in patients with skeletal muscle myopathies [see Warnings and Precautions (5.1)]
in patients with known hypersensitivity to succinylcholine. Severe anaphylactic reactions to succinylcholine have been reported [see Warnings and Precautions (5.2)]
after the acute phase of injury following major burns, multiple trauma, extensive denervation of skeletal muscle, or upper motor neuron injury, which may result in severe hyperkalemia and cardiac arrest [see Warnings and Precautions (5.4)]
in patients with known or suspected genetic susceptibility to malignant hyperthermia [see Warnings and Precautions (5.5), Clinical Pharmacology (12.5)]
5 Warnings and Precautions
5.5 Malignant HyperthermiaAdditions and/or revisions underlined
In susceptible individuals, succinylcholine may trigger malignant hyperthermia, a skeletal muscle hypermetabolic state leading to high oxygen demand. Fatal outcomes of malignant hyperthermia have been reported.
The risk of developing malignant hyperthermia increases with the concomitant administration of succinylcholine and volatile anesthetic agents. QUELICIN can induce malignant hyperthermia in patients with known or suspected susceptibility based on genetic factors or family history, including those with certain inherited ryanodine receptor (RYR1) or dihydropyridine receptor (CACNA1S) variants. [see Contraindications (4), Clinical Pharmacology (12.5)].
Signs consistent with malignant hyperthermia may include hyperthermia, hypoxia, hypercapnia, muscle rigidity (e.g., jaw muscle spasm), tachycardia (e.g., particularly that unresponsive to deepening anesthesia or analgesic medication administration), tachypnea, cyanosis, arrhythmias, hypovolemia, and hemodynamic instability. Skin mottling, coagulopathies, and renal failure may occur later in the course of the hypermetabolic process.
Successful treatment of malignant hyperthermia depends on early recognition of the clinical signs. If malignant hyperthermia is suspected, discontinue all triggering agents (i.e., volatile anesthetic agents and succinylcholine), administer intravenous dantrolene sodium, and initiate supportive therapies. Consult prescribing information for intravenous dantrolene sodium for additional information on patient management. Supportive therapies include administration of supplemental oxygen and respiratory support based on clinical need, maintenance of hemodynamic stability and adequate urinary output, management of fluid and electrolyte balance, correction of acid base derangements, and institution of measures to control rising temperature.
