  • tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.

Dosage Of Uridine Triacetate

Uridine triacetate comes as granules to take by mouth. It is usually taken with or without meals four times a day (every 6 hours) for 20 doses. Take uridine triacetate at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take uridine triacetate exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Mix the granules into 3 to 4 ounces (9 to 120 grams) of soft food such as applesauce, pudding, or yogurt. Take the mixture right away (within 30 minutes of mixing the granules with food) without chewing the granules and then drink at least 4 ounces (120 mL) of water to make sure that you swallow all of the medication.

If you are preparing a dose for a child, measure the dose using measuring teaspoons (accurate to 1/4 teaspoon) or a scale (accurate to at least 0.1 gram). Dispose of any remaining granules; do not use granules left in the packet for your next doses.

If you vomit within 2 hours of taking a dose, take another full dose as soon as possible after the vomiting episode, and then take your next dose at the regularly scheduled time.

Uridine triacetate granules can be given through certain types of feeding tubes. If you have a feeding tube, ask your doctor how you should take the medication. Follow the directions carefully.

It is important that you take all 20 doses of uridine triacetate, even if you feel well. Do not stop taking uridine triacetate without talking to your doctor.

Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.


Keep all appointments with your doctor.

Do not let anyone else take your medication.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
