begin using a medication, be sure to inform your doctor of any medical conditions
or allergies you may have, any medications you are taking, whether you are pregnant
or breast-feeding, and any other significant facts about your health. These factors
may affect how you should use this medication.
Allergy: Some people who are allergic to sulfonamide antibiotics also experience allergic reactions to triamterene - hydrochlorothiazide because of the hydrochlorothiazide component. Before you take this medication, inform your doctor about any previous adverse reactions you have had to medications, especially sulfonamide (sulfa) antibiotics.
Contact your doctor at once if you experience signs of an allergic reaction such as skin rash, itching, difficulty breathing, or swelling of the face and throat.
Diabetes: People with diabetes may find that their blood sugar level is less controlled when taking triamterene - hydrochlorothiazide. If you have diabetes, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Gout: This medication may cause a flare-up of gout symptoms. If you have gout or a history of gouty arthritis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Kidney stones: Triamterene has been found in kidney stones. If you have kidney stones or a history of kidney stones, discuss with your doctor
how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Potassium levels: Increased blood levels of potassium, though uncommon, are potentially the most severe side effect with this medication. This is more likely to occur if you are 60 years and older.
Warning signs or symptoms of high potassium include numbness, muscular weakness, fatigue, paralysis of the extremities, and slow heart rate. If this condition occurs, stop taking the medication.
Potassium supplements: Potassium supplementation, either in the form of medication or as a potassium-rich diet, should not be used at the same time as triamterene - hydrochlorothiazide. Triamterene helps recycle potassium from the urine, back into the body. When it is combined with potassium supplements, high levels of potassium in the blood may result.
Low levels of potassium may also occur for some of the people taking this medication because of the potassium-lowering effect of hydrochlorothiazide.
Pregnancy: Hydrochlorothiazide crosses the placenta and may affect an unborn baby. Triamterene - hydrochlorothiazide should
not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: Hydrochlorothiazide passes into breast milk, and triamterene may pass into breast milk. If you are a breast-feeding mother and are taking triamterene - hydrochlorothiazide, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children.
