Medical guidance required: Dosing information here is for educational purposes. Your healthcare provider will determine the appropriate dose based on your specific condition, kidney function, other medications, and medical history. Never adjust your dose without consulting your doctor or pharmacist.
DOSAGE AND ADMINISTRATION The usual dosage of pentoxifylline in extended-release tablet form is one tablet (400 mg) three times a day with meals. While the effect of pentoxifylline may be seen within 2 to 4 weeks, it is recommended that treatment be continued for at least 8 weeks. Efficacy has been demonstrated in double-blind clinical studies of 6 months duration. Digestive and central nervous system side effects are dose related. If patients develop these effects it is recommended that the dosage be lowered to one tablet twice a day (800 mg/day). If side effects persist at this lower dosage, the administration of pentoxifylline should be discontinued. In patients with severe renal impairment (creatinine clearance below 30 mL/min) reduce dose to 400 mg once a day. Dosing information cannot be provided for patients with hepatic impairment.
