Furosemide is a loop diuretic prescribed to reduce swelling and water retention in our body. This drug is usually used for congestive heart failure, edema associated with other conditions, and even hypertension. This is marketed under the brand name of Lasix
Furosemide 40mg is used to control hypertension, but, this is not a cure for this condition. This is oftentimes used in conjunction with other hypertensive drugs. The recommended dose for treating hypertension is furosemide 40 mg twice daily.
How can furosemide 40mg help in controlling hypertension? Furosemide 40mg decreases water retention in our body. Through this, our blood volume decreases resulting to a lessened pressure in our blood vessels. Imagine a water hose where there is a strong flow of water. The pressure will be increased if the faucet will be turned on to the fullest allowing a more supply of water. This is what happens to our blood vessels also. The more blood volume, the higher the pressure. But, again this is not a cure for hypertension. We need to treat the underlying cause.
Furosemide 40mg comes in a tablet form and is taken orally. Usually, it is taken once daily in the morning. But, it could also be taken twice a day. Take your Lasix dosage as prescribed by your doctor.
After administration of furosemide 40mg, the onset of action is within one hour, and the increased urine output usually lasts for about 6-8 hours. The diuretic effect of furosemide 40mg can cause electrolyte imbalance, such as reduction of sodium and chloride. Therefore, it should be used cautiously under medical supervision. Visit your doctor regularly and keep your appointments with him. Your blood pressure should be checked habitually, and blood tests should be completed sometimes.
Always follow your doctor’s instructions in taking your Lasix dosage. The usual beginning oral dose as a treatment for edema in adult clients is 20-80 mg. An increased dose or the same dose may be given 6-8 hours after. Lasix dosage may be increased 20-40 mg every 6-8 hours until the anticipated outcome occurs. The effective Lasix dosage may be administered once or twice daily. Doses more than 6 mg/kg are not suggested
Patients taking furosemide 40mg tablets should be instructed that they may experience symptoms due to excessive fluid and electrolyte losses. This may include muscle cramps, weakness, dizziness, confusion, thirst, blurred vision, and headache. If this becomes severe while taking your Lasix dosage, be sure to seek medical attention right away. Postural hypotension could also occur especially when there is an abrupt change in position. This can be managed usually by slowly getting up and changing your position. Allow yourself to sit for a while after getting up from bed before standing.
With your Lasix dosage, hypokalemia may also occur. This is decreased potassium levels in our blood. This can be fatal. Therefore, potassium supplements are given. It is recommended for patients taking furosemide 40mg that they should increase their intake of potassium rich foods such as banana, prunes, raisins, and orange juice.
