Isosorbide Mononitrate Er 30mg Side Effects
(Newest replies first)

Isosorbide MN ER 30 MG - I took this drug - 1 each day - for 1 1/2 months to relieve the steady pain of Esophageal Spasms and developed severe headaches. Thought at first it was from arthritis in my back so went a chiropractor for 1 month - no help there. Stopped taking this drug for 4 nights and "WOW" No headaches. I will NOT take anymore of this medication.

I had every test you can think of, even an angiogram - no sign of an angina and my heart is in very good condition. I was told this drug is also used for Esophageal Spasms. It is not for me and I know that t does help those with anginas.

Your headache indeed was because of the medication, had you needed it for a HEART condition then the headache would most likely eased up or gone away completely after the first week or two. The medication dilates the blood vessels throughout your body - including the brain - causing the headache - but works great for those of us with actual daily, frequent angina.

Who told you to take it to treat that?

Isosorbide Mononitrate is usually used to treat angina pectoris, because it dilates the blood vessels and can reduce the pressure on them.

Thus, it is not a pain reliever, nor a muscle relaxant.

And headaches are a very common side effect of this medication, due to the very nature of how it works.
