Product introduction

Isonorm 20 Tablet is used to prevent heart-related chest pain (angina). It works by relaxing and widening blood vessels so blood can flow more easily to the heart. This medicine will not treat an angina attack that has already begun.

Isonorm 20 Tablet may be taken with or without food. Your doctor will decide the dose and how often you should take them. This may change from time to time depending on how well they are working. You should take this medicine as it has been prescribed and keep taking it, even if you feel well. This medicine helps to prevent chest pain in the future. If you stop taking it, your risk of chest pain will increase, especially if you stop taking them suddenly. Lifestyle changes such as diet, exercise, and not smoking may help this medication work better.

You can develop tolerance to this medicine over time, which means that the same dose becomes less effective. You have to stick to a really specific dosing schedule to prevent this from happening.

The most common side effects include headache, flushing, upper respiratory tract infection, abdominal pain, allergic reaction, chest pain, and diarrhea. If these symptoms bother you or do not go away, your doctor may suggest ways of preventing or reducing them. Some can be reduced by taking painkillers, drinking plenty of fluids, and avoiding alcohol. 

Before taking this medicine tell your doctor if you have low blood pressure, increased pressure in the eye (glaucoma), kidney disease, or heart failure. Also let your doctor know if you are taking any other medicines as some may affect, or be affected by, this medicine and some may be dangerous to take with it. You should not take any medicine for erectile dysfunction with this medicine. If you are pregnant or breastfeeding, ask your doctor if this medicine is suitable. Your doctor may regularly monitor your blood pressure and heart rate during the treatment with this medicine.

Yes, Isonorm 20 Tablet may affect the heart rate. Isonorm 20 Tablet causes a decrease in blood pressure. This decrease in blood pressure further causes a decrease in the heart rate (bradycardia).

Consult your doctor in case you do not feel well after taking this medicine or if you notice a change in your heart rate.

What if I forget to take a dose of Isonorm 20 Tablet?

You can take the forgotten dose of Isonorm 20 Tablet if you remember it within 12 hours. However, if you remember it after 12 hours of the scheduled time, then skip the missed dose and continue with the next dose.

Can I stop taking Isonorm 20 Tablet after sometime?

No, do not stop taking this medicine without talking to your doctor. Stopping it suddenly may increase your chances of having an anginal attack. If you have any concerns regarding Isonorm 20 Tablet consult your doctor.

What are the symptoms of an overdose of Isonorm 20 Tablet?

Taking more than the recommended dose of Isonorm 20 Tablet may cause throbbing headache, reddening of the skin, chills along with sweating, nausea, vomiting, and a fast heartbeat. Seek emergency help and consult your doctor immediately if you take more than the recommended dose of this medicine.

Can Isonorm 20 Tablet be taken at night?

Depending upon the dose, your doctor may recommend you to take this medicine once or twice daily. When a single dose is recommended, then it is preferred to be taken in the morning. If taking it twice a day, maintain a gap of 7 hours between the two doses. This helps decrease the chances of Isonorm 20 Tablet becoming ineffective (tolerance) after some time.

Does Isonorm 20 Tablet lower BP?

Yes, Isonorm 20 Tablet can cause a fall in blood pressure. This medicine widens the blood vessels and decreases the resistance in them, causing a fall in blood pressure. This fall in blood pressure may in turn decrease the heartbeat which can lead to angina. This medicine should be avoided in people who already have low blood pressure. Discuss with your doctor if you have any concerns.

Can I take sildenafil while taking Isonorm 20 Tablet?

No, you should not take sildenafil along with Isonorm 20 Tablet. Both these medicines lower blood pressure and belong to the same class.
