Product introduction

Megalis 20 Tablet is used to treat erectile dysfunction (ED) in men and pulmonary arterial hypertension (PAH). It increases blood flow to the penis to help men get an erection. In PAH, it relaxes or widens the blood vessels inside the lungs, which reduces blood pressure in the lungs.

Megalis 20 Tablet may be taken on an empty stomach or with a meal. It should be strictly taken as advised by your doctor. The medicine when taken for ED will only help you to get an erection if you are sexually stimulated. You should take it about one hour before you plan to have sex. The amount of time it takes to work varies from person to person, but it normally takes between 30 minutes and one hour. Only take it if you need it and it has been prescribed to you by a doctor.

The most common side effects of this medicine are flushing, headache, blurred vision, muscle pain, stomach upset, nausea, back pain, and respiratory tract infection. Talk to your doctor if the side effects bother you or will not go away.

Megalis 20 Tablet can be dangerous to take it along with medicines called nitrates (often given for chest pain). Do not take this medicine if you have severe heart or liver problems, if you have recently had a stroke or heart attack or if you have low blood pressure. Let your doctor know if you suffer from these or any other health problems before taking it. You should not drive if this medicine makes you feel dizzy. Avoid drinking alcohol while taking this medicine as it can lead to side effects.


Benefits of Megalis Tablet

In Treatment of Pulmonary arterial hypertension (PAH)

Pulmonary arterial hypertension can cause shortness of breath, tiredness, dizziness, chest pain and swelling in your ankles and legs. It is caused by thickening of walls of the arteries that supply your lungs making it hard for blood to get through. Megalis 20 Tablet belongs to a group of medicines called PDE5 inhibitors. It works by relaxing blood vessels and can help lower the blood pressure in the arteries of your lungs. You will be able to carry out your daily activities more easily and feel less tired or dizzy. Take it regularly, as prescribed even if you think it is not working or if you feel better.

In Treatment of Erectile dysfunction

Megalis 20 Tablet belongs to a group of medicines called PDE5 inhibitors. It works by relaxing the blood vessels in your penis. This allows blood to flow into the penis and produce an erection when sexually aroused. This medicine will only help get an erection if you are sexually stimulated. It is very effective but needs to be taken at least 30 minutes before sexual activity.

Do not take this medicine if you also take medicines called nitrates (often given for chest pain).

How Megalis Tablet works
