Torsemide-oral

Torsemide comes as a tablet to take by mouth. It usually is taken once a day. To help you remember to take torsemide, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take torsemide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Torsemide controls high blood pressure and edema but does not cure these conditions. Continue to take torsemide even if you feel well. Do not stop taking torsemide without talking to your doctor.

This medicine is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Before taking torsemide,

• tell your doctor and pharmacist if you are allergic to torsemide, sulfonamide medications, any other medications, or any of the ingredients in torsemide tablets. Ask your pharmacist or check the patient information for a list of the ingredients.
• tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: aminoglycoside antibiotics such as amikacin, gentamicin (Garamycin), or tobramycin (Bethkis, Tobi), aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil, Motrin, others) and naproxen (Aleve, Naprosyn, others); corticosteroids such as betamethasone (Celestone), budesonide (Entocort), cortisone (Cortone), dexamethasone (Decadron, Dexpak, Dexasone, others), fludrocortisone (Floriner), hydrocortisone (Cortef, Hydrocortone), methylprednisolone (Medrol, Meprolone, others), prednisolone (Prelone, others), prednisone (Rayos), and triamcinolone (Aristocort, Azmacort); corticotropin (ACTH, H.P., Acthar Gel); digoxin (Lanoxin), ethacrynic acid (Edecrin), indomethacin (Indocin), lithium (Lithobid), medications for high blood pressure or pain, and probenecid (Probalan, Probenemid). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
• if you are taking cholestyramine (Questran), take it 4 hours before or 1 hour after toresemide.
• tell your doctor if you have or have ever had kidney disease. Your doctor may tell you not to take toresemide.
• tell your doctor if you have or have ever had diabetes, gout, heart, or liver disease.
• tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. Do not breastfeed while taking this medicine. If you become pregnant while taking torsemide, call your doctor.
• you should know that torsemide may cause dizziness, lightheadedness, and fainting when you get up too quickly from a lying position. This is more common when you first start taking torsemide. To avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up. Alcohol can add to these side effects.

Take the missed dose as soon as you remember it. However, if it is almost time for your next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

Tell your doctor if any of these symptoms are severe or do not go away:

• frequent urination
• cough
• constipation
• diarrhea
• hearing loss
• ringing in ears
• sore throat
• headache
• upset stomach

Some side effects can be serious. If you have any of these symptoms, call your doctor immediately or get emergency medical treatment:

• dry mouth; thirst; nausea; vomiting; weakness, tiredness; drowsiness; restlessness; confusion; muscle weakness, pain, or cramps; fast heartbeat and other signs of dehydration and electrolyte imbalance
• rapid, excessive weight loss
• vomiting blood
• chest pain
• difficulty breathing or swallowing
• blisters or peeling skin
• hives
• rash
• itching
• ongoing pain that begins in the stomach area, but may spread to the back

If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).

Keep this medicine in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

• Keep this drug stored at room temperature, 15 C to 30 C (59 F to 86 F).
• The FDA approved torsemide in August, 1993.
