USES
Sulfonamide antibiotics are a family of related drugs that have activity
against many types of bacteria. This group of medications is often used to
treat urinary tract infections, as well as other infections. These
medications kill the bacteria responsible for the infection.
TREATMENT
Sulfonamide antibiotics should be taken with a full glass of water on an
empty stomach (either one hour before or two hours after a meal). Several
additional glasses of water should also be taken every day (unless your doctor
directs you to do otherwise). Sulfonamide antibiotics work best when the
level of the 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 to take four doses a day, the doses should be spaced about
six hours apart.
If the liquid suspension or emulsion form of the sulfonamides has been
prescribed for you, be sure to shake the bottle well. The contents tend to
settle on the bottom of the bottle, so it is necessary to shake the container
to distribute the ingredients evenly and equalize the doses. Be sure to use
specially marked droppers or spoons to accurately measure the correct amount
of liquid. Household teaspoons vary in size and may not give you the correct
dosage.
If you miss a dose, take the missed dose as soon as possible, unless it
is almost time for your next dose. In that case, if you are taking two doses
a day, space the missed dose and the following dose five to six hours apart;
if you are taking three or more doses a day, space the missed dose and the
following dose two to four hours apart, or double the next dose. Then return
to your regular dosing schedule.
It is very important to continue to take these medications for the entire
time prescribed by your doctor (usually ten days), even if the 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 your
infection could recur.
SIDE EFFECTS
Minor.
Diarrhea, dizziness, headache, loss of appetite, nausea, or vomiting. As
your body adjusts to the medication, these side effects should disappear.
These drugs can increase your sensitivity to sunlight. You should,
therefore, avoid prolonged exposure to sunlight and sunlamps. Wear protective
clothing and sunglasses; and use an effective sunscreen, but not one that
contains para-aminobenzoic acid (PABA). PABA interferes with the
antibacterial activity of this medication.
Major.
Tell your doctor about any side effects that are persistent or
particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about
aching of joints and muscles; blood in the urine; difficulty in swallowing;
itching; lower back pain; pain while urinating; pale skin; redness,
blistering, or peeling of the skin; skin rash; sore throat and fever; swelling
of the front part of the neck; unusual bleeding or bruising; unusual
tiredness; or yellowing of the eyes or skin. Also, if your symptoms of
infection seem to be getting worse rather than improving, you should contact
your doctor.
INTERACTIONS
Sulfonamides interact with several types of drugs:
1. Para-aminobenzoic acid products (sunscreens) can decrease the
effectiveness of the sulfonamides.
2. The activity and side effects of anticoagulants (blood thinners, such
as warfarin), oral antidiabetic medications, methotrexate, aspirin, phenytoin,
and thiopental may be increased when sulfonamides are also taken.
3. Oxyphenbutazone, phenylbutazone, methenamine, probenecid, and
sulfinpyrazone can increase the toxicity of the sulfonamides.
BE SURE TO TELL YOUR DOCTOR about any medications you are currently
taking, especially any of those listed above.
WARNINGS
* Before starting to take this medication, tell your doctor about any
unusual or allergic reactions you have had to any medications, especially to
sulfonamide antibiotics or other sulfa drugs, including diuretics (water
pills), dapsone, sulfoxone, oral antidiabetics, and oral antiglaucoma
medication.
* Tell your doctor if you now have or if you have ever had
glucose-6-phosphate dehydrogenase (G6PD) deficiency, liver disease, porphyria,
or kidney disease.
* Before having surgery or any other medical or dental treatment, be sure
to tell your doctor or dentist that you are taking a sulfonamide antibiotic.
* 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, and
you should not use it for other infections, unless your doctor specifically
directs you to do so.
* Be sure to tell your doctor if you are pregnant. These medications, if
given to a woman late in pregnancy, can be toxic to the fetus. Also, tell
your doctor if you are breast-feeding an infant. Sulfonamides can pass into
breast milk and may cause side effects in a small number of nursing
infants--those who have glucose-6-phosphate dehydrogenase (G6PD) deficiency.
In addition, you should not give sulfonamides to an infant less than one month
of age, unless your doctor specifically directs you to do so.
