Uses for hydroxocobalamin
Hydroxocobalamin injection is an emergency treatment (antidote) used in patients with known or suspected cyanide poisoning. Cyanide poisoning is a life-threatening condition that requires immediate medical attention. It is more likely to occur if you breathe smoke from closed-space household and industrial fires, or you have swallowed or breathe cyanide (a chemical poison), or your skin is exposed to cyanide. Signs and symptoms include chest tightness, confusion, dilated or enlarged pupils, nausea or vomiting, rapid or shallow breathing, trouble breathing, or seizures.
Hydroxocobalamin is to be given only by or under the direct supervision of a doctor.
Before using hydroxocobalamin
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For hydroxocobalamin, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to hydroxocobalamin or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Appropriate studies have not been performed on the relationship of age to the effects of hydroxocobalamin injection in the pediatric population. Safety and efficacy have not been established.
Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of hydroxocobalamin injection in the elderly.
Breastfeeding
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
Interactions with medicines
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Interactions with food/tobacco/alcohol
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
Other medical problems
The presence of other medical problems may affect the use of hydroxocobalamin. Make sure you tell your doctor if you have any other medical problems, especially:
- Allergy to cyanocobalamin or hydroxocobalamin—Use with caution.
- Hypertension (high blood pressure) or
- Hypotension (low blood pressure)—Use with caution. May make these conditions worse.
Proper use of hydroxocobalamin
A doctor or an emergency care provider will give you hydroxocobalamin. Hydroxocobalamin is given through a needle placed in one of your veins for 15 minutes.
Hydroxocobalamin comes with a patient information insert. It is very important that you read and understand this information. Be sure to ask your doctor about anything you do not understand.
Precautions while using hydroxocobalamin
Your doctor will check your progress closely while you are receiving hydroxocobalamin. This will allow your doctor to see if the medicine is working properly. Blood tests will also be needed to check for unwanted effects.
Hydroxocobalamin may cause serious allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have a rash, itching, chest tightness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using hydroxocobalamin.
Hydroxocobalamin may cause high or low blood pressure. Tell your doctor right away if you have fast, slow, pounding, or uneven heartbeats while receiving hydroxocobalamin.
Hydroxocobalamin may cause skin redness and make your skin more sensitive to sunlight. This effect may last for up to 2 weeks after you have received hydroxocobalamin. Avoid being in the sun while your skin is red. Use a sunscreen when you are outdoors. Avoid sunlamps and tanning beds.
