Frequently asked questions for Losartan


Q. Can I feel dizzy after taking Losartan?

Yes, the use of Losartan can make you feel dizzy. This may occur when you suddenly get up from a lying or sitting position. To lower the chance of feeling dizzy or passing out, rise slowly if you have been sitting or lying down.

Q. Is Losartan a good blood pressure medicine?

Losartan is used by many people for reducing blood pressure levels. This medicine generally has very few side effects. In addition to lowering blood pressure, it also protects kidney function in high blood pressure patients having diabetes and impaired kidney function (diabetic nephropathy). It is also used to treat chronic heart failure when treatment with other medicines fails to prove effective. It also helps to decrease the risk of stroke in patients who are hypertensive and have thicker left ventricle (heart chamber).

Q. What are some of the lifestyle changes I should make while using Losartan?

Lifestyle changes play a major role in keeping you healthy if you are taking Losartan. Avoid taking excess salt in your diet and find ways to reduce or manage stress in your life. Practice yoga or meditation or take up a hobby. Ensure that you have a sound sleep every night as this also helps to reduce stress levels and helps to keep your blood pressure normal. Stop smoking and alcohol consumption as this helps in lowering your blood pressure and preventing heart problems. Exercise regularly and take a balanced diet that includes whole grains, fresh fruits, vegetables, and fat-free products. Consult your doctor if you need any further guidance to get the maximum benefit of Losartan and to keep yourself healthy.

Q. For how long do I need to take Losartan?

You may have to take Losartan for a long term, even life long. Losartan only controls blood pressure but does not cure it. Talk to your doctor in case you have any concerns regarding Losartan, but do not stop taking it without consulting the doctor.

Q. Does Losartan cause weight gain?

No, Losartan does not cause weight gain. However, if the medicine starts affecting your kidney function then your body may swell due to the accumulation of water, resulting in weight gain. Call your doctor if you experience unexplained weight gain or swelling in your feet, ankles, or hands.

Q. How long does Losartan take to work?

The blood pressure-lowering effect of Losartan can be seen after about 6 hours of taking it. The effect of the medicine lasts for about 24 hours. However, you may have to take the medicine for about 3-6 weeks to see the full benefits.

Q. When and how should Losartan be taken?

Take Losartan exactly as per your doctor’s advice. Losartan tablets are meant for oral intake. Swallow the tablet with water. You can take it with or without food. The dose will depend on the condition you are being treated for. It is recommended that you take your first dose before bedtime, as it can make you dizzy. After taking the first dose, you can take it at any time of the day but try to take it at the same time each day.

Q. Is Losartan bad for the kidneys?

Yes, Losartan may impair the kidney function of patients, especially those who have severe heart failure, chronic kidney disease, or narrow or blocked blood vessels that lead to the kidneys (renal artery stenosis). It may also affect kidney function in patients who have experienced severe fluid loss or dehydration due to vomiting, diarrhea, or excessive use of diuretics. Therefore, Losartan should be used cautiously in these patients and their kidney function should be regularly monitored.

Q. What is the most important information that I need to know about Losartan?

Taking Losartan during the last 6 months of pregnancy can cause serious harm or even endanger the life of the unborn baby. Hence, it is important to inform the doctor if you are pregnant or plan to become pregnant. If you become pregnant while taking Losartan, stop taking Losartan and call your doctor immediately.

Q. What are the long-term side effects of Losartan?

Long-term use of Losartan is generally considered to be safe. However, in some cases, long-term use of Losartan may adversely affect the functioning of the kidneys. Therefore, the doctor may prescribe regular blood tests to keep a track of how well the kidneys are working.
