Dosage Of Papaverine
Papaverine comes as a tablet and extended-release (long-acting) capsule to take by mouth. The tablet usually is taken three to five times a day at evenly spaced intervals. The extended-release capsule usually is taken every 8-12 hours. Do not crush, chew, or divide the extended-release capsules. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take papaverine exactly as directed.
Papaverine may be habit-forming. Do not take larger doses, take it more often, or for a longer period than your doctor tells you to.
Papaverine controls high blood pressure but does not cure it. Continue to take papaverine even if you feel well. Do not stop taking papaverine without talking to your doctor.
Other
Keep all appointments with your doctor and the laboratory. Your doctor may order certain tests to monitor your liver function.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
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.
