IMPORTANT: HOW TO USE THIS INFORMATION: This does not encompass all details and information about this product, nor does it guarantee that it is safe, useful, or suitable for you.

TRIAMTERENE - ORAL
COMMON BRAND NAME(S): Dyrenium
WARNING: This medication can raise your body's potassium levels. This effect is more likely to occur in the elderly and in patients with kidney disease, diabetes, or serious illness. Potassium levels must be closely monitored on a regular basis while taking this medication. If not treated, very high potassium levels can sometimes be fatal. If you develop any of the following symptoms, tell your doctor immediately: muscle weakness, slow/irregular heartbeat.
USES: Triamterene is used to reduce surplus fluid in the body (edema) created by ailments including congestive heart failure, liver illness, and kidney disease. Eliminating additional water helps to minimize fluid in the lungs so that breathing is more manageable. In addition, it assists in reducing the swelling of the arms, legs, and abdomen.
Triamterene is a certain kind of "water pill" (potassium-sparing diuretic). It works by increasing the amount of urine you make, allowing your body to get rid of extra salt (sodium) and water while also preventing the kidneys from getting rid of too much potassium.
OTHER USES: This part of the drug label includes uses that have not been approved by the professional labeling for the drug, yet they might be recommended by your healthcare provider. Only utilize this drug for a condition that is specified in this section if it has been prescribed by your healthcare provider.
This drug may also be used with other medications to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.
HOW TO USE: You should take this medication after meals to minimize gastrointestinal distress, usually once or twice a day or as recommended by your doctor. It is advisable not to take this medication within 4 hours prior to going to sleep in order to avoid needing to wake up to urinate. If you have questions regarding your dosage regimen, please consult your doctor or pharmacist.
The dosage is based on your medical condition and response to therapy. For the treatment of edema, do not take more than 300 milligrams daily. For the treatment of high blood pressure in adults, the recommended maximum daily dose is 100 milligrams, especially if taking triamterene with other medications for this condition.
This drug may increase the potassium levels in your blood. Consult your doctor or pharmacist before using any products containing potassium (e.g., potassium supplements such as potassium chloride, salt substitutes). Do not increase the amount of potassium in your diet (e.g., bananas, orange juice) unless approved by your doctor.
Use this medication regularly in order to get the most benefit from it. To help you remember, take it at the same time(s) each day. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. It may take up to several weeks before the full benefit of this drug takes effect.
Do not stop taking this medication without first consulting your doctor. Some conditions may become worse when the drug is abruptly stopped. Your dose may need to be gradually decreased.
Inform your doctor if your condition does not improve or if it worsens (e.g., swelling increases, your routine blood pressure readings increase).
SIDE EFFECTS: See also Warning section.
You may experience lightheadedness, exhaustion, a headache, a stomachache, or loose bowels as your body adjusts to the medicine. You can also be more sensitive to sunlight. If any of these effects linger or become worse, please inform your doctor or pharmacist right away.
Take into account that your doctor prescribed this medicine since the benefit to you is more than the possibility of side effects. Generally, many people who use this medication don't have severe side effects.
Infrequently, triamterene may cause a loss of too much body water (dehydration) and salt (minerals). Tell your doctor immediately if you have any of these unlikely but serious symptoms of dehydration or mineral loss: very dry mouth, thirst, muscle cramps/weakness, fast/irregular heartbeat, nausea, vomiting, severe dizziness, unusual decrease in the amount of urine, fainting, confusion, seizures.
Tell your doctor immediately if any of these unlikely but serious side effects occur: signs of a kidney stone (e.g., pain in the side/back/abdomen, painful urination, blood in the urine, fever, chills), joint pain (e.g., big toe pain).
Tell your doctor immediately if any of these rare but very serious side effects occur: signs of infection (e.g., fever, persistent sore throat), easy bruising/bleeding, stomach/abdominal pain, persistent nausea/vomiting, unusual/persistent tiredness, yellowing eyes/skin, dark urine, unusual change in the amount of urine (not including the normal increase in urine when you first start this drug).
A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: kidney problems (e.g., kidney stones), liver problems, other untreated salt/mineral imbalance (e.g., low sodium blood level), loss of too much body water (dehydration), gout, conditions causing low folic acid blood levels (e.g., alcoholic cirrhosis, pregnancy).
If you have diabetes, triamterene may affect your blood sugar levels. Check your blood sugar levels regularly as directed and share the results with your doctor. Tell your doctor immediately if you have symptoms of high blood sugar such as increased thirst/urination. Your doctor may need to adjust your anti-diabetic medication or diet.
This medication may make you more sensitive to the sun. Avoid prolonged sun exposure, tanning booths, and sunlamps. Use a sunscreen and wear protective clothing when outdoors.

To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position. Significant loss of body water from too much sweating, vomiting, or diarrhea can also lower your blood pressure and worsen dizziness. Drink plenty of fluids to prevent these effects and dehydration. If you are on restricted fluid intake, consult your doctor for further instructions. Contact your doctor if you are unable to drink fluids or if you have persistent diarrhea/vomiting.
