-
- STORAGE
-
- Procainamide tablets and capsules should be stored in tightly closed
- containers in a cool, dry place. Exposure to moisture causes deterioration of
- this medication.
-
- USES
-
- Procainamide is used to treat heart arrhythmias. It corrects irregular
- heartbeats to achieve a more normal rhythm.
-
- TREATMENT
-
- To increase absorption, take procainamide with a full glass of water on
- an empty stomach one hour before or two hours after a meal. However, if it
- upsets your stomach, ask your doctor if you can take it with food or milk.
- Try to take it at the same time(s) each day. Procainamide works best
- when the amount of drug in your bloodstream is kept at a constant level. This
- medication should, therefore, be taken at evenly spaced intervals day and
- night. For example, if you are to take this medication four times per day,
- the doses should be spaced six hours apart.
- The sustained-release tablets should be swallowed whole. Breaking,
- chewing, or crushing these tablets destroys their sustained-release activity
- and possibly increases the side effects.
- If you miss a dose of this medication and remember within two hours, take
- the missed dose immediately. If more than two hours have passed (four hours
- for the sustained-release tablets), do not take the missed dose; just return
- to your regular dosing schedule. Do not double the next dose.
-
- SIDE EFFECTS
-
- Minor.
-
- Bitter taste in the mouth, diarrhea, dizziness, dry mouth, loss of
- appetite, nausea, stomach upset, or vomiting. These side effects should
- disappear as your body adjusts to the medication.
- If you feel dizzy, sit or lie down for a while; get up slowly from a
- sitting or reclining position, and be careful on stairs.
- To relieve mouth dryness, chew sugarless gum or suck on ice chips or a
- piece of hard candy.
-
- Major.
-
- Tell your doctor about any side effects that are persistent or
- particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about
- chest pain, chills, confusion, depression, fainting, fatigue, fever,
- giddiness, hallucinations, itching, joint pain, palpitations, rash, sore
- throat, unusual bleeding or bruising, or weakness.
-
- INTERACTIONS
-
- Procainamide interacts with several other types of medications:
- 1. The combination of digoxin and procainamide can lead to an increase in
- side effects to the heart.
- 2. Procainamide can block the effectiveness of neostigmine,
- pyridostigmine, and prostigmine.
- 3. Cimetidine, ranitidine, and amiodarone can increase the blood levels
- of procainamide, which can lead to an increase in side effects.
- Before starting to take procainamide, TELL YOUR DOCTOR about any
- medications you are currently taking.
-
- WARNINGS
-
- * Tell your doctor about unusual or allergic reactions you have had to
- any medications, especially to procainamide, procaine, lidocaine, benzocaine,
- or tetracaine.
- * Before starting this medication, be sure to tell your doctor if you now
- have or if you have ever had asthma, heart block, kidney disease, liver
- disease, myasthenia gravis, or systemic lupus erythematosus.
- * If this drug makes you dizzy, do not take part in any activity that
- requires alertness, such as driving a car or operating potentially dangerous
- machinery.
- * Before having surgery or any other medical or dental treatment, be sure
- to tell your doctor or dentist that you are taking this medication.
- * Do not stop taking this drug without first consulting your doctor.
- Stopping procainamide abruptly may cause a serious change in the activity of
- your heart. Your doctor may therefore want to reduce your dosage gradually.
- * If you are taking Procan-SR and you occasionally notice something in
- your stool that looks like a tablet, it does not mean that the drug is not
- being absorbed. The drug is "held" in a wax core designed to release the
- medication slowly. The wax core is eliminated in the stool after the drug has
- been absorbed.
- * Some of these products contain the color additive FD&C Yellow No. 5
- (tartrazine), which can cause allergic-type symptoms (rash, shortness of
- breath, fainting) in certain susceptible individuals.
- * Be sure to tell your doctor if you are pregnant. Although this drug
- appears to be safe, extensive studies in pregnant women have not been
- conducted. Also, tell your doctor if you are breast-feeding an infant. It is
- not known whether procainamide passes into breast milk.
