How is dimethyl sulfoxide given?
Dimethyl sulfoxide is injected directly into the bladder using a catheter or syringe inserted into the urethra (the tube for passing urine out of your bladder). A healthcare provider will give you this medicine in a clinic setting.
After dimethyl sulfoxide is placed into the bladder, you will need to hold the medicine in for 15 minutes before emptying your bladder.
If you have severe cystitis, you may be given an anesthesia to numb your pelvic area before you are treated with dimethyl sulfoxide.
Dimethyl sulfate is usually given once every 2 weeks until your symptoms are relieved. Follow your doctor's dosing instructions very carefully.
Your doctor may also want you to take other medicines to treat pain or bladder spasm. Read the medication guide or patient instructions provided with each of your medicines.
While using dimethyl sulfoxide, you may need frequent blood and urine tests.
Because dimethyl sulfoxide can affect your eyes, you may also need to have eye exams before and during treatment.
What happens if I miss a dose?
Call your doctor for instructions if you miss an appointment for your dimethyl sulfoxide treatment.
What happens if I overdose?
Since this medicine is injected into the bladder and not into the bloodstream, an overdose is unlikely to occur.
What should I avoid while receiving dimethyl sulfoxide?
Follow your doctor's instructions about any restrictions on food, beverages, or activity.
Dimethyl sulfoxide side effects
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Tell your caregivers if you feel severe discomfort or irritation when the medicine is inserted, or while you are holding it in your bladder. This discomfort may become less noticeable over time with repeat treatments.
You may notice a garlic- or onion-like taste in your mouth while you are receiving dimethyl sulfoxide. This effect may last for several hours after you receive the medicine, and you may also sense these odors on your breath or skin. This is a normal side effect of dimethyl sulfoxide and is not cause for concern.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
