How Losamax 25 works

Losamax H Tablet is a combination of two medicines: Losartan and Hydrochlorothiazide, which lowers the blood pressure effectively. Losartan is an angiotensin receptor blocker (ARB). It works by blocking the hormone angiotensin thereby relaxing blood vessels. This allows the blood to flow more smoothly and the heart to pump more efficiently. Hydrochlorothiazide is a diuretic that removes extra water and certain electrolytes from the body. Over time it also relaxes blood vessels and improves blood flow.

How to take Losamax 25

Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Losamax H Tablet may be taken with or without food, but it is better to take it at a fixed time.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.

Missed dose and overdose

If you miss a dose

Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.

If you take too much

An overdose of this medicine can cause a severe fall in blood pressure, with dizziness, fainting and a fast or slow pulse. It can cause severe dehydration, a sharp fall in blood pressure and dangerous salt imbalances. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.

Side effects of Losamax 25

Warnings and precautions

Stand up slowly for the first few days — dizziness on rising is common when you start or your dose goes up. Stop and seek urgent care if your lips, tongue, face or throat swell, or you have difficulty breathing. A persistent dry, tickly cough can be caused by the ACE inhibitor group; tell your doctor rather than stopping on your own, as an alternative exists. Your doctor will check your kidney function and potassium after starting and after any dose change. Do not use salt substitutes containing potassium without asking your doctor. Take it in the morning so that passing urine does not disturb your sleep. Your doctor will check your salts and kidney function with blood tests — do not skip them. Report muscle cramps, marked weakness, confusion or an irregular heartbeat; these can be signs your potassium or sodium has fallen. In hot weather or during an illness with vomiting or loose motions, tell your doctor — you may become dehydrated quickly.

Do not take Losamax if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Must not be used in pregnancy — it can seriously harm the developing baby. Not for people with narrowing of both kidney arteries, or a history of swelling of the face and throat caused by this group of medicines. Not for people who are unable to pass urine, or who are severely dehydrated.

Interactions with other medicines

Anti-inflammatory painkillers reduce the effect and can harm the kidneys when combined. Potassium supplements, potassium-sparing water tablets and salt substitutes can push potassium too high. Lithium levels rise when taken with these medicines. Anti-inflammatory painkillers blunt the effect and can strain the kidneys. Lithium and digoxin levels are affected; tell your doctor if you take either. Potassium-sparing types must not be combined with potassium supplements without supervision.

How to store Losamax 25

Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
