Ablysinol (Dehydrated Alcohol) – Injection: Uses, Side Effects, Dosages, Interactions


What Is Ablysinol?

Ablysinol (dehydrated alcohol) injection is a prescription medication. It is a sterile, preservative-free solution of greater than 99% by volume of ethyl alcohol.

Ablysinol is used during a septal ablation procedure. It is injected into the heart to target the area that is thickened. Dehydrated alcohol causes cells to die, allowing the thickened area to shrink to a more normal size. This allows for improved blood flow in and from the heart.

Ablysinol is administered under the supervision of a qualified cardiologist, usually in a hospital setting.

What is Ablysinol Used For?

Ablysinol improves exercise capacity in adults with symptomatic hypertrophic obstructive cardiomyopathy who are not candidates for open heart surgery.

Hypertrophic obstructive cardiomyopathy is a genetic condition where the wall (septum) between the two bottom chambers of the heart thickens. This can block or reduce the blood flow from the left ventricle to the aorta.

How to Take Ablysinol

Ablysinol should only be administered under the supervision of a qualified cardiologist who is experienced in this type of procedure.


Your healthcare provider will manage the storage of Ablysinol. Ablysinol comes in a single-dose glass ampule. It must be stored at room temperature—between 68 and 77 degrees Fahrenheit. Do not refrigerate or freeze the medication. It is also highly flammable and needs to be kept away from any heat sources.

How Long Does Ablysinol Take to Work?

Responses to Ablysinol vary for each patient. Ask your healthcare provider how long they think it will take for Ablysinol to work for you.

Dosage: How Much Ablysinol Should I Take?

The amount of Ablysinol to be administered depends on several factors. Your healthcare provider will determine the correct dosage of this medication for you.


The following changes (modifications) should be kept in mind when using Ablysinol:

Severe allergic reaction: Avoid using Ablysinol if you have a known allergy to it or its ingredients. Ask your healthcare provider for a complete list of the ingredients if you’re unsure.

Pregnancy: It might be safe to take Ablysinol while you’re pregnant. Tell your healthcare provider if you are or plan to become pregnant. You can discuss the benefits and risks of having Ablysinol administered during your pregnancy.

Adults over 60: Adults over the age of 60 may have an increased risk of experiencing a heart block during the procedure or needing a permanent pacemaker.

Children: This drug is not prescribed for use in children.

Missed Dose

Do your best to keep your appointments with your healthcare provider before, during, and after Ablysinol administration.

Overdose: What Happens If I Take Too Much Ablysinol?

If too much Ablysinol injection is used, there is a risk of a heart attack. There is a direct relationship between the amount of dehydrated alcohol used and the size of the iatrogenic myocardial infarction (heart attack).

The procedure should be stopped at the maximum dose of 5 milliliters (mL)—even if the optimal outcome is not reached.

What Happens If I Overdose on Ablysinol?

If you think you or someone else may have overdosed on Ablysinol, call a healthcare provider or the Poison Control Center (1-800-222-1222).
