FAQs

Q. Is New GTN harmful?

New GTN is safe if taken for prescribed duration in prescribed doses advised by your doctor.

Q. Is New GTN a vasodilator?

New GTN belongs to a group of medicines called nitrate vasodilators. It works by relaxing the blood vessels of the heart, reducing the strain on the heart and making it easier to pump blood.

Q. Why does New GTN cause a headache?

Headache is a side effect of New GTN. The headache could be due to the dilation of cerebral arteries (those arteries supplying different parts of the brain). It usually disappears within several days of continued treatment.

Q. How does New GTN relieve angina pectoris?

New GTN belongs to a group of medicines called nitrate vasodilators. It acts by the release of nitric oxide which causes the dilatation (widening) of the blood vessels and relaxes the muscles. This reduces the strain on the heart by making it easier to pump blood. In this manner, New GTN relieves pain in angina pectoris.

Q. How does New GTN reduce blood pressure?

New GTN reduces the blood pressure by dilating the blood vessels and decreasing the workload of the heart. However, it is not used for the treatment of high blood pressure.

Q. Is New GTN a strong antibiotic? Which infections does it treat?

New GTN is a broad-spectrum antibiotic. This means that it is used to treat a variety of bacterial infections. It is used to treat infection affecting the lungs (pneumonia) and complicated infections of the urinary tract, abdomen, and skin and soft tissue infections. It also treats bacterial infection of the membranes that surround the brain and spinal cord (meningitis) and infections that occur during or after delivery.

Q. Is New GTN effective against bacteria only? Can it be used for any type of bacterial infection?

Yes, New GTN is effective against bacteria only but not all bacteria. It is not effective against virus or fungi. New GTN is effective against some bacteria which include Staphylococcus aureus, Streptococcus pneumoniae, S. pyogenes, S. viridans group, etc. New GTN should only be used to treat or prevent infections against which it is effective.

Q. My cousin was receiving New GTN for severe skin infection when she had a fit and New GTN was stopped. Was the fit due to New GTN?

Seizures or fits have been reported with the use of New GTN. However, fits are more likely to occur in patients with a history of seizures or a brain lesion (wound, ulcer, abscess, or tumor) or patients having bacterial meningitis or compromised kidney function.

Q. My friend has a history of epilepsy and she was on valproic acid while receiving treatment with New GTN, still she had an episode of seizure. Why?

Your friend should have communicated to the doctor that she was receiving valproic acid for epilepsy. New GTN interferes with the working of valproic acid, making it less effective. It is because of this that she had an episode of seizure. Generally, in cases like these, the doctor prescribes a different medicine.

Q. For how long will I need to take New GTN?

The length of the treatment will be decided by your doctor, depending on your general health, the type of infection you have and how well you respond to New GTN.

Q. What if New GTN does not suit me?

It is common to have minor side effects such as nausea, vomiting, diarrhea and headache but generally these settle down. If the side effects bother you, tell your doctor immediately. The doctor will give you an alternative medicine. Serious side effects are very rare. In case you develop serious side effects, seek immediate medical advice.

Q. Does it matter if I miss or stop New GTN?

It is important that you do not stop the treatment without consulting your doctor. Stopping the treatment may bring back the infection or you may develop resistance to New GTN. The same applies if you are forgetful in taking the suggested doses. It is recommended that you do not miss doses. If you do, take the missed dose as soon as you can and take the next dose as planned so that you stick to the same overall daily dose.

Q. Even though New GTN is used for skin infections, can it cause any skin-related problems?

Serious skin reactions are rare, but these have been reported with the use of New GTN. Inform your doctor before starting New GTN if you are allergic to a medicine or any antibiotic. These serious skin reactions are type of allergic reactions, but they can endanger life. So, if you notice any rash along with fever or peeling of skin, you should alert your doctor who will immediately discontinue New GTN.
