Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Bleeding: The use of pentoxifylline has been associated with bleeding and prolonged clotting time. The risk of bleeding may be increased by combined treatment with blood-thinning medications such as warfarin. Your doctor will monitor you while you are taking pentoxifylline. If you experience any abnormal bleeding (e.g., bleeding around your eyes or blood in your stool), seek immediate medical attention.
Blood pressure: People with low blood pressure may be more sensitive to side effects with the use of this medication. Your doctor will monitor you while you are taking pentoxifylline.
Liver or kidney disease: People with liver or kidney disease should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Pentoxifylline is not recommended for people with severely reduced kidney or liver function.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: Pentoxifylline passes into breast milk. If you are breast-feeding and are taking pentoxifylline, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children below the age of 18 years.
Seniors: Seniors may be more sensitive to the side effects of this medication. Your doctor will monitor you while you are taking this medication.
