Pro-Triazide

How does this medication work? What will it do for me?

This combination product contains 2 medications: triamterene and hydrochlorothiazide. Both these medications belong to the class of medications called diuretics ("water pills"). They are used in combination to treat edema (fluid retention) that occurs with congestive heart failure and liver or kidney disorders. It is also used to treat mild-to-moderate high blood pressure.

This medication works by making the body lose excess water and salt. Triamterene, called a potassium-sparing diuretic, helps the body to keep potassium in, while hydrochlorothiazide causes the body to lose potassium. Therefore, potassium supplements are usually not required with this medication.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here.

Are there any other precautions or warnings for this medication?

Before you 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.

Driving and using machines: Triamterene - hydrochlorothiazide can cause dizziness or lightheadedness, which may affect your ability to perform tasks that require special attention, such as driving or operating machinery. Avoid performing any potentially hazardous tasks, including driving, until you have determined how this medication affects you.

Glaucoma: Hydrochlorothiazide may cause the symptoms of glaucoma (increased pressure in the eye) to suddenly occur. If you have glaucoma, 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. Report any changes in vision to your doctor as soon as possible while you are taking this medication.

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.

Liver function: If you have decreased liver function or liver disease, 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 old or over.

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.

Sensitivity to sunlight: This medication may increase the sensitivity of the skin to sunlight, increasing the risk of sunburn. Avoid exposure to sunlight for long periods of time, particularly between the hours of 10 am and 2 pm, while you are taking this medication and for 7 days after your last dose. Wear a broad-spectrum sunscreen and lip balm with an SPF of 30 or higher. If you notice any unusual skin rash or peeling, contact your doctor immediately.

Skin cancer: Recent studies of hydrochlorothiazide have connected long-term use of the medication with an increased risk of developing non-melanoma skin cancer. Check your skin regularly for unusual growths or discolouration and report any changes to your doctor as soon as possible.

Systemic lupus erythematosus: This medication can worsen or activate the symptoms of lupus. If you experience swollen and painful joints, fever, fatigue, or rash on the nose and cheeks while taking this medication, contact your doctor.

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 breast-feeding and 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.
