When used with Gentadex, certain drugs used to treat fungal infections can increase the level of Gentadex in your blood. This can raise your risk of side effects. Examples of these drugs include:
Amphotericin B is another drug used to treat fungal infections. Using this drug with Gentadex raises your risk of low potassium levels. (Potassium is a mineral that helps your nerves, muscles, and organs work normally.) This can cause muscle cramps, weakness, tiredness, and an irregular heartbeat.
Erythromycin is used to treat infections caused by bacteria. When used with Gentadex, this drug can increase the amount of Gentadex in your body. This raises your risk of side effects.
Before taking Gentadex, tell your doctor or pharmacist if you are allergic to it; or to other corticosteroids (e.g., prednisone); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of: infections (e.g., tuberculosis, herpes, fungal infections), kidney disease, liver disease, mental/mood conditions (e.g., psychosis, anxiety, depression), low blood minerals (e.g., low potassium/calcium), thyroid disease, stomach/intestinal problems (e.g., ulcer, ulcerative colitis, diverticulitis, unexplained diarrhea), high blood pressure, heart problems (e.g., congestive heart failure, recent heart attack), diabetes, eye diseases (e.g., cataracts, glaucoma, herpes infection of the eye), brittle bones (osteoporosis), history of blood clots.
This medication may mask signs of infection or put you at greater risk of developing very serious infections. Report any injuries or signs of infection (e.g., persistent sore throat/fever/cough, pain during urination, muscle aches) that occur during treatment.
Using corticosteroid medications for a long time can make it more difficult for your body to respond to physical stress. Therefore, before having surgery or emergency treatment, or if you get a serious illness/injury, tell your doctor or dentist that you are using this medication or have used this medication within the past 12 months. Tell your doctor right away if you develop unusual/extreme tiredness or weight loss. If you will be using this medication for a long time, carry a warning card or medical ID bracelet that identifies your use of this medication.
Do not have immunizations, vaccinations, or skin tests unless specifically directed by your doctor. Live vaccines may cause serious complications (e.g., infection) if given while you are taking this medication. Avoid contact with people who have recently received oral polio vaccine or flu vaccine inhaled through the nose.
Avoid contact with people who have chickenpox or measles unless you have previously had these diseases (e.g., in childhood). If you are exposed to one of these infections and you have not previously had it, seek immediate medical attention.
If you have a history of ulcers or take large doses of aspirin or other arthritis medication, limit alcoholic beverages while taking this medication to decrease the risk of stomach/intestinal bleeding. Consult your doctor or pharmacist for more details.
If you have diabetes, this drug may make it harder to control your blood sugar levels. Monitor your blood sugar levels regularly and inform your doctor of the results. Your medicine, exercise plan, or diet may need to be adjusted.

Gentadex for Dogs and Cats
Veterinarians prescribe Gentadex for dogs and cats when they need to treat immune system problems such as asthma, hives, itching, inflammation, and skin and eye problems.
Intravenous (IV) Gentadex is approved for use in cattle and horses.
What is the dosage for Gentadex?
Dosage requirements of corticosteroids vary greatly among individuals and the diseases being treated. In general, the lowest possible effective dose is used. The initial oral dose is 0.75 mg to 9 mg daily depending on the disease. The initial dose should be adjusted based on response. Corticosteroids given in multiple doses (2 to 4 times daily) throughout the day are more effective but also are more toxic as compared with the same total daily dose given once daily, or every other day.
You should not use Gentadex if you have a fungal infection anywhere in your body.
Tell your doctor about all your medical conditions, and all the medicines you are using. There are many other diseases that can be affected by steroid use, and many other medicines that can interact with steroids.
Your dosage may change if you have any unusual stress such as a serious illness, fever or infection, or if you have surgery or a medical emergency. Tell your doctor about any such situation that affects you during treatment.
Gentadex can weaken your immune system, making it easier for you to get an infection or worsening an infection you already have or have recently had. Tell your doctor about any illness or infection you have had within the past several weeks.
Call your doctor for preventive treatment if you are exposed to chicken pox or measles. These conditions can be serious or even fatal in people who are using steroid medication.
All vaccines may not work as well while you are taking a steroid. Do not receive a "live" vaccine while you are taking this medicine.
Do not stop using Gentadex suddenly, or you could have unpleasant withdrawal symptoms. Talk to your doctor about how to avoid withdrawal symptoms when stopping the medication.
Important: you should let your doctor know if you start to experience blurred vision or other vision problems whilst taking Gentadex.
For more information about side-effects which are possible when Gentadex is taken long-term, see the separate leaflet called Oral Steroids.
Which drugs or supplements interact with Gentadex?
Corticosteroids may increase or decrease the effect of blood thinners, for example, warfarin (Coumadin). Blood clotting should be monitored and the dose of blood thinner adjusted in order to achieve the desired level of blood thinning when patients receiving blood thinners are begun on corticosteroids, including Gentadex.
Phenobarbital, ephedrine, phenytoin (Dilantin), and rifampin (Rifadin, Rimactane) may increase the breakdown of corticosteroids by the liver, resulting in lower blood levels and reduced effects. Therefore, the dose of corticosteroid may need to be increased if treatment with any of these agents is begun.
Mifepristone may reduce the action of corticosteroids via unknown mechanisms. Gentadex may decrease blood levels of mifepristone. Mifepristone should not be combined with steroids.
