    Furosemide contraindication


    Furosemide is a potent loop diuretic with rapid action. The drug inhibits chloride reabsorption in the ascending limb of the Loop of Henle and inhibits tubular sodium transport, causing major loss of sodium and chloride. Furosemide is rapidly absorbed from the gastrointestinal tract (bioavailability 60-70%). Increased urinary losses of potassium, calcium and phosphate (large doses only) also occur. The half life in adults is 2 hours, but this is approximately 8 times greater in neonates. It is approximately 99% bound to plasma proteins, and excreted mainly unchanged by the kidneys. Furosemide belongs to a group of medicines called loop diuretics (also known as water pills). Furosemide is given to help treat fluid retention (edema) and swelling that is caused by congestive heart failure, liver disease, kidney disease, or other medical conditions. It works by acting on the kidneys to increase the flow of urine. Furosemide is also used alone or together with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure.

    The parenteral administration of furosemide is indicated in cases where oral administration is not feasible or not efficient (for example in case of reduced intestinal absorption) or when a quick effect is required. To achieve optimum efficacy and suppress counter-regulation, a continuous furosemide infusion is generally to be preferred to repeated bolus injections. Where continuous furosemide infusion is not feasible for follow-up treatment after one or several acute bolus doses, a follow-up regimen with low doses given at short intervals (approx. 4 hours) is to be preferred to a regimen with higher bolus doses at longer intervals. Generally, Furosemide should be administered intravenously. Intramuscular administration must be restricted to exceptional cases where neither oral nor intravenous administration is feasible. It must be noted that intramuscular injection is not suitable for the treatment of acute conditions such as pulmonary oedema. In the absence of conditions requiring a reduced dose (see below) the initial dose recommended for adults and adolescents over 15 years, is of 20 mg to 40 mg furosemide by intravenous (or in exceptional cases intramuscular) administration; the maximum dose varying according to individual response. In either case, the rate of infusion should not exceed 4mg/minute. • acute hypercalcaemia (dehydration results from vomiting and diuresis - correct before giving furosemide). Treatment of hypercalcaemia with a high dose of furosemide results in fluid and electrolyte depletion - meticulous fluid replacement and correction of electrolyte required.• Symptomatic hypotension leading to dizziness, fainting or loss of consciousness can occur in patients treated with furosemide, particularly in the elderly, patients on other medications which can cause hypotension and patients with other medical conditions that are risks for hypotension The possibility of hypokalaemia should be taken into account, in particular in patients with cirrhosis of the liver, those receiving concomitant treatment with corticosteroids, those with an unbalanced diet and those who abuse laxatives. Regular monitoring of the potassium, and if necessary treatment with a potassium supplement, is recommended in all cases, but is essential at higher doses and in patients with impaired renal function. It is especially important in the event of concomitant treatment with digoxin, as potassium deficiency can trigger or exacerbate the symptoms of digitalis intoxication (see section 4.5). A potassium-rich diet is recommended during long-term use. Frequent checks of the serum potassium are necessary in patients with impaired renal function and creatinine clearance below 60ml/min per 1.73m2 body surface area as well as in cases where furosemide is taken in combination with certain other drugs which may lead to an increase in potassium levels (see section 4.5 & refer to section 4.8 for details of electrolyte and metabolic abnormalities)Frequent BUN in first few months of treatment, periodically thereafter. Long-term/high-dose BUN should regularly be measured. Marked diuresis can cause reversible impairment of kidney function in patients with renal dysfunction.

    I'm taking Prednisone for buzzing in the head/ear and it stops it. The awful buzzing stopped for 3 weeks after I used it for 5 days. So I went to ER and they said I had so much wax in my right ear that it was impacted and covering my ear drum so they cleaned it out. She's been taking it for 5 days and feel sick to her stomach, headaches - the only thing that has left is the pain in her ears. My problems is that I have this feeling like when you drink way too much alcohol and your head is all over the place. I was given this for vertigo, because the PA thought i had fluid in my ears. I've been to an ENT and three doctors, and none saw any fluid in my ear. The ENT said, "Oh, just air not pressurizing properly." I'm assuming (since he did not elaborate or do further tests to see why) that my Eustachian Tube is not opening and closing properly due to inflammation. I had no buzzing for two days; also they prescribed the Prednisone again for 5 days. Each pill was 5mg, the first day I started with 6 pills, THATS 30mg!! the dumb PA in my doctors office gave me prednisone for vertigo!!!!!!! I was on 60mg of prednisone for Graves Disease with eye involvement for 21 days, long enough for the Tapazol (thyroid med) to kick in. My daughter had a severe sinus infection with fluid/ear pressure buildup so painful, the doctor prescribed 20 mg of Prednisone, taken 3 times a day (60 mg) for 7 days, reduce to 2 for 2 days, then 1 for 1 day to keep from 'damaging her ear drum because the fluid buildup was so bad'. I sporadically have fluid/fullness in my ear which I believe is due to allergies, but I am afraid of taking allergy meds because I was recently diagnosed with Subclinical hyperthyroid disorder and have been told that sinus/allergy medications and amplify the effects of the meds. Alot of people on this site under prednisone has said the same. Irritability, night sweats, weak, tired and could not sleep. It all started as you described- a head cold and clogged ears. I take a course of prednisone a couple of times a year to combat vertigo, which accompanies the disease. she thought I had fluid in my ear causing the imbalance. When all was said and done, my dizziness aka VERTIGO, was a result from very low iron, my hemoglobin was 8!!! Anyway, just goes to show you are dumb and lazy PA's and some doctors are. I started noticing the moon face after only 21 days, but at the same time could start tapering off since the thyroid med had kicked in. I have been on 20mg a day and have had a moon face for 3 days. I have been prescribed Prednisone 50 mg for 5 days for. Tinnitus Ringing in the Ears Treatment and Diagnosis Steroids for hearing loss or vertigo - Dizziness-and-

    When it comes to seeing their doctor, many men will figure out a way not to. Men have fewer routine encounters with the medical system as young people. They worry they’ll find out something is wrong and they’re uncomfortable with physical exams, particularly the prostate check. There is one medical problem, however, that tends to send men straight to the doctor: erectile dysfunction (ED). Experts in men’s health say American men who have ED come in seeking prescriptions for one of the three medications available for the condition: Cialis, Levitra, or Viagra. They discover, though, that most health insurers don’t cover the medications, so many men wind up paying as much as to per pill out of pocket for them. That cost has helped create an illegal online market and demand for ED drugs from Canadian pharmacies. ED almost always has an underlying cause relating to a man’s physical or mental health, says David Gremillion, MD, of the University of North Carolina School of Medicine.
