Tiplab 100mg Tablet (also called labetalol hydrochloride) is a prescription medicine used to treat high blood pressure (hypertension). Doctors often use it for high blood pressure during pregnancy, including pre-eclampsia, a pregnancy condition with high blood pressure. In hospitals, an injection form is used to bring very high blood pressure down quickly. Tiplab 100mg Tablet contains one active ingredient, labetalol hydrochloride. It comes as film-coated tablets in several strengths, and as an injection for hospital use only. It blocks two kinds of receptors, alpha and beta, which are signal points in the body. This relaxes blood vessels and stops the heart from beating faster than it needs to. Lowering blood pressure this way reduces strain on the heart, kidneys, brain and blood vessels over time.

Tiplab 100mg Tablet (also called labetalol hydrochloride) is a prescription medicine used to treat high blood pressure (hypertension). Doctors often use it for high blood pressure during pregnancy, including pre-eclampsia, a pregnancy condition with high blood pressure. In hospitals, an injection form is used to bring very high blood pressure down quickly. Tiplab 100mg Tablet contains one active ingredient, labetalol hydrochloride. It comes as film-coated tablets in several strengths, and as an injection for hospital use only. It blocks two kinds of receptors, alpha and beta, which are signal points in the body. This relaxes blood vessels and stops the heart from beating faster than it needs to. Lowering blood pressure this way reduces strain on the heart, kidneys, brain and blood vessels over time.
Tiplab 100mg Tablet lowers blood pressure in two ways at once. Most medicines in the beta-blocker family only slow the heart and reduce how hard it pumps. Tiplab 100mg Tablet also blocks alpha-1 receptors in the walls of blood vessels. This lets the vessels widen, so blood flows with less pressure. Because both actions happen together, blood pressure falls without the strong, fast heartbeat the body sometimes uses to make up for widened vessels.
Doctors prescribe Tiplab 100mg Tablet tablets for long-term control of high blood pressure. They may be used alone or with other blood pressure medicines, such as water tablets (diuretics). The medicine is widely used for high blood pressure in pregnancy because doctors have long experience with it in pregnant women. In hospital, Tiplab 100mg Tablet injection is given slowly into a vein for severe high blood pressure that needs fast control. Only trained staff give it, with close monitoring.
The tablet is taken by mouth, usually twice a day. Food increases how much of the medicine the body absorbs. Taking it with meals in the same way each day keeps its effect steady. The full blood pressure effect of a new dose can take a day to a few days to appear.
Tiplab 100mg Tablet needs medical supervision. The most common problem is dizziness or light-headedness when standing up, especially in the first weeks or after a dose increase. Rarely, the medicine can cause serious liver injury. Report unusual tiredness, dark urine or yellowing of the skin straight away.
Tiplab 100mg Tablet must not be used by people with any of these:
It is generally avoided in other lung conditions that narrow the airways, such as chronic bronchitis or emphysema.
It should not be stopped suddenly. Stopping a beta-blocker all at once can make chest pain worse in people with heart disease. If it needs to be stopped, your doctor will lower the dose slowly over a week or two.
Common Side Effects (Usually Mild and may lessen with continued use)
Serious Side Effects (Seek Urgent Medical Attention)
Your body makes natural "stress chemicals", such as adrenaline and noradrenaline. These attach to receptors, which work like locks on cells. Two kinds of receptors matter most for blood pressure:
Tiplab 100mg Tablet blocks both. It is a "non-selective" beta-blocker. This means it blocks beta receptors in the heart and also in other places, such as the airways. Blocking them slows the heart and reduces how hard it pumps. At the same time, it blocks alpha-1 receptors, so blood vessels relax and widen.
Taken by mouth, its beta-blocking effect is about three times stronger than its alpha-blocking effect. It also gently stimulates beta-2 receptors in blood vessel walls, which helps the vessels widen a little more.
The two main actions support each other. Usually, when blood vessels widen, the body tries to make up for it by speeding up the heart. Because Tiplab 100mg Tablet also blocks the heart's beta receptors, it limits that speeding up. Blood pressure falls mainly because blood flows more easily through the vessels, while the amount of blood the heart pumps stays fairly steady. Because it also blocks beta receptors in the airways, Tiplab 100mg Tablet can tighten the breathing passages in people with asthma.
Taking too much Tiplab 100mg Tablet can cause:
What to do: Get emergency medical help straight away or go to the nearest hospital. Take the medicine pack with you. While waiting, the person should lie flat with their legs raised. Do not try to make them vomit. In hospital, doctors can give treatments that raise the heart rate and blood pressure and support breathing.
Seek medical help urgently if you have:
