Administration of other calcium channel blockers to patients with wide complex tachycardia (QRS 0.12 seconds) has resulted in hemodynamic deterioration and ventricular fibrillation. It is anticipated that these guidelines would help health professionals to prevent extravasation during IV and central vein injection and to promote patient safety should extravasation occur in any case. Special drug management for care of the extravasation. Avoid taking herbal supplements containing St. John's wort at the same time you are taking diltiazem. The patient must be informed of the scope of the problem (Supplement 5). 512 0 obj <> endobj Hypotension - Decreases in blood pressure associated with diltiazem hydrochloride injection therapy may occasionally result in symptomatic hypotension (3.2%). Venous shock can occur when injecting very cold medication or when medication is injected at a rapid pace. You should not stop using diltiazem suddenly. Diltiazem | RxWiki Accessibility Metoprolol Cold Hydrocortisone 50-200 mg Give via 5-10 SQ or TD injections into area of extravasation Medication Thermal Therapy Antidote Dose Treatment Nitroglycerin Cold Hydrocortisone 50-200 mg Give via 5-10 SQ or TD injections into area of extravasation Norepinephrine Heat Nitroglycerin 2% paste n/a Apply thin layer to area of extravasation q 6 hr x 24 hr Reduction in mean arterial pressure correlated linearly with diltiazem plasma concentration in a group of hypertensive patients. For Direct Intravenous Bolus The use of local warming is recommended for the extravasation of nonDNA-binding vesicants. Patients taking other drugs that are substrates of CYP450 3A4, especially patients with renal and/or hepatic impairment, may require dosage adjustment when starting or stopping concomitantly administered diltiazem in order to maintain optimum therapeutic blood levels. National Library of Medicine Clipboard, Search History, and several other advanced features are temporarily unavailable. If response is inadequate, a second dose may be administered after 15 minutes. In severe cases, extravasation may cause tissue dysfunction or physical defects, resulting in a delay of attempted treatment, patients distrust, and numerous other issues. 0000001694 00000 n <<893FCAAD4A261745BEDEB8B64953C410>]/Prev 46654/XRefStm 1178>> Guideline for the management of extravasation of a cytotoxic agent or a monoclonal antibody used in the treatment of malignant disease: version 4.2. pounding heartbeats or fluttering in your chest; a light-headed feeling, like you might pass out; shortness of breath (even with mild activity), swelling, rapid weight gain; nausea, upper stomach pain, itching, tired feeling, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes); or. Competitive in vitro ligand binding studies have shown that diltiazem binding is not altered by therapeutic concentrations of digoxin, phenytoin, hydrochlorothiazide, indomethacin, phenylbutazone, propranolol, salicylic acid, tolbutamide, or warfarin. Diltiazem hydrochloride injection is for direct intravenous bolus injection and continuous intravenous infusion. Treatment depends on the nature of the offending substance; one approach is to localise and neutralise the substance whereas another is to spread and dilute it. Calcium channel blockers - Mayo Clinic Vesicants are inherently toxic and can cause pain, inflammation, and burn-like injury including blistering, sloughing, deep tissue damage, and necrosis. Diltiazem prolongs the sinus cycle length. Proceedings of the Infusion Nurses Society Annual Meeting; 1997 May; Salt Lake City, USA. - Check for blood backflow before injection to ensure that the catheter is positioned in the vein.

Total radioactivity measurement following short intravenous administration in healthy volunteers suggests the presence of other unidentified metabolites which attain higher concentrations than those of diltiazem and are more slowly eliminated; half-life of total radioactivity is about 20 hours compared to 2 to 5 hours for diltiazem.

Dosage: The dose is 150 units (1 mL) given as five 0.2 mL injections into the extravasation site at the leading edge; change the needle after each injection. 0000003340 00000 n Antidotes for the care of the extravasation.
