-
- TYPE OF DRUG
-
- Penicillin antibiotic
-
- INGREDIENT
-
- nafcillin
-
- DOSAGE FORMS
-
- Tablets (500 mg)
- Capsules (250 mg)
- Oral solution (250 mg per 5-ml spoonful)
-
- STORAGE
-
- Nafcillin tablets and capsules should be stored at room temperature in
- tightly closed containers. The oral solution should be stored in the
- refrigerator in a tightly closed container. Any unused portion of the
- solution should be discarded after 14 days because the drug loses its potency
- after that time. This medication should never be frozen.
-
- USES
-
- Nafcillin is used to treat a wide variety of bacterial infections,
- especially those caused by Staphylococcus bacteria. It acts by severely
- injuring the cell membranes of the infecting bacteria, thereby preventing them
- from growing and multiplying. Nafcillin kills susceptible bacteria, but it is
- not effective against viruses, parasites, or fungi.
-
- TREATMENT
-
- Nafcillin should be taken on an empty stomach or with a glass of water
- one hour before or two hours after a meal. This medication should never be
- taken with fruit juices or carbonated beverages because the acidity of these
- drinks destroys the drug in the stomach.
- The oral solution should be measured carefully with a specially designed
- 5-ml measuring spoon. An ordinary kitchen teaspoon is not accurate enough.
- Nafcillin works best when the level of medicine in your bloodstream is
- kept constant. It is best, therefore, to take the doses at evenly spaced
- intervals day and night. For example, if you are taking four doses a day, the
- doses should be spaced six hours apart.
- If you miss a dose of this medication, take the missed dose immediately.
- However, if you do not remember to take the missed dose until it is almost
- time for your next dose, take it; space the following dose about halfway
- through the regular interval between doses; and then return to your regular
- dosing schedule. Try not to skip any doses.
- Take this drug for the entire time prescribed by your doctor (usually
- seven to 14 days), even if your symptoms disappear before the end of that
- period. If you stop taking the drug too soon, resistant bacteria are given a
- chance to continue growing, and the infection could recur.
-
- SIDE EFFECTS
-
- Minor.
-
- Diarrhea, heartburn, nausea, or vomiting. These side effects should
- disappear as your body adjusts to the medication.
-
- Major.
-
- Tell your doctor about any side effects that are persistent or
- particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about
- bloating, chills, cough, darkened tongue, difficult or painful urination,
- difficulty in breathing, fever, irritation of the mouth, muscle aches, rash,
- rectal or vaginal itching, severe diarrhea, sore throat, or yellowing of the
- skin or eyes. Also, if your symptoms of infection seem to be getting worse
- rather than improving, you should contact your doctor.
-
- INTERACTIONS
-
- Nafcillin interacts with several other types of medications:
- 1. Probenecid can increase the blood concentrations of this medication.
- 2. Nafcillin may decrease the effectiveness of oral contraceptives (birth
- control pills), and pregnancy could result. You should, therefore, use
- another form of birth control while taking this medication. Discuss this with
- your doctor.
- BE SURE TO TELL YOUR DOCTOR about any medications you are currently
- taking, especially those listed above.
-
- WARNINGS
-
- * Tell your doctor about unusual or allergic reactions you have had to
- any medications, especially to nafcillin, penicillins, cephalosporin
- antibiotics, penicillamine, or griseofulvin.
- * Tell your doctor if you now have or if you have ever had kidney
- disease, asthma, or allergies.
- * This medication has been prescribed for your current infection only.
- Another infection later on, or one that someone else has, may require a
- different medicine. You should not give your medicine to other people or use
- it for other infections, unless your doctor specifically directs you to do so.
- * Diabetics taking nafcillin should know that this drug can cause a
- false-positive sugar reaction with a Clinitest urine glucose test. To avoid
- this problem while taking nafcillin, you should switch to Clinistix or
- Tes-Tape to test your urine for sugar.
- * Be sure to tell your doctor if you are pregnant. Although nafcillin
- appears to be safe during pregnancy, extensive studies in humans have not been
- conducted. Also, tell your doctor if you are breast-feeding an infant. Small
- amounts of this medication pass into breast milk and may temporarily alter the
- bacterial balance in the intestinal tract of the nursing infant, resulting in
- diarrhea.
