What Factors Affect Lasix® Dosage?

Factors affecting a Lasix® dosage include the condition it is being used to treat, a patient's response to Lasix®, his existing medical conditions, and any other medication he's taking. For people with high blood pressure, the usual starting Lasix® dosage is 40 mg two times a day. Starting Lasix® dosage for those diagnosed with water retention varies from 20 mg to 600 mg. Lasix&reg is a medication classified as a diuretic and is used to treat fluid retention and high blood pressure.

Although Lasix® is generally well tolerated, side effects even at a low Lasix® dosage can occur. In most cases, side effects from this medication are typically mild and can be treated effectively by the healthcare provider. Side effects may include constipation or diarrhea, headaches, sensitivity to the sun, vertigo, and visual changes. Diuretics, or water pills, help the body rid itself of excess fluid, which decreases edema, or swelling.

More serious side effects of Lasix® include jaundice, decrease urination, lightheadedness, and a rapid heart rate. When side effects occur, the healthcare provider can adjust the Lasix® dosage so that side effects will be minimized. Rarely, severe allergic reactions can occur, including wheezing, difficulty breathing, chest pain, and swelling of the throat. If these symptoms occur, emergency medical treatment needs to be started to avoid the risk of multiple organ failure.

Since Lasix® is classified as a Category C medication, it has the potential to harm an unborn child. If, however, the healthcare provider believes the benefits outweigh the potential risks, he may still recommend it to the pregnant woman. It is important to note, however, that this medication should only be given to pregnant women if absolutely necessary. Other medications may be safer when treating high blood pressure and fluid retention.

High blood pressure, although typically asymptomatic, can cause heart disease, stroke, and kidney failure. Although medication can be an integral part of a hypertension treatment plan, other remedies may be similarly important. These include maintaining a healthy weight, eating a diet rich in fruits, vegetables and fiber, quitting smoking, and getting enough exercise.

Depending upon the Lasix® dosage, the doctor may consider augmenting treatment with minerals such as magnesium and potassium. These minerals may work in conjunction with the diuretic to further lower blood pressure without increasing the Lasix® dosage. People who are taking diuretics or other prescription medications should not take nutritional supplements without first consulting with their healthcare providers.
