Can Isonit 30mg Tablet SR 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.

Discuss with your doctor if you have any concerns.

Can I take sildenafil while taking Isonit 30mg Tablet SR?

No, you should not take sildenafil along with Isonit 30mg Tablet SR. Both these medicines lower blood pressure and belong to the same class.
