Swallow whole. Do not break, crush, or chew before swallowing.
Ask your health care provider any questions you may have about how to use Trental.
Drug Class and Mechanism
Trental is a xanthine derivative blood flow enhancer. It works by thinning the blood and improving red blood cell flexibility, causing the blood to flow more freely through the veins.
If you miss a dose of Trental and are taking it regularly, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Store Trental at room temperature, between 68 and 77 degrees F (20 and 25 degrees C). Store away from heat, moisture, and light. Do not store in the bathroom. Keep in a tight, light-resistant container. Keep Trental out of the reach of children and away from pets.
Do not use Trental if:
you are allergic to any ingredient in Trental or to methylxanthines (e.g., theophylline, caffeine, theobromine);
you have had recent bleeding in the brain or eye.
Contact your doctor or health care provider right away if any of these apply to you.
Trental may cause dizziness or blurred vision. These effects may be worse if you take it with alcohol or certain medicines. Use Trental with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
Tell your doctor or dentist that you take Trental before you receive any medical or dental care, emergency care, or surgery.
It may take 2 to 4 weeks to notice improvement in your condition, and up to 8 weeks for maximum relief.
Use Trental with caution in the elderly; they may be more sensitive to its effects.
Pregnancy and breast-feeding: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Trental while you are pregnant. Trental is found in breast milk. Do not breast-feed while taking Trental.
