"I took the first Imdur in early morning, within 2 hours, I had a horrible headache, neck pain, and shoulder pain. 60 mg dose. After 18 hrs, I still have severe neck pain and a horrible migraine. I haven’t slept and feel anxious."

"I do get a slight headache every morning, nothing dramatic, and it does lower my blood pressure, but I have severe joint pain throughout my body. I am only taking 10 mg once a day and I will have to go to 5 mg to see if that will help or eliminate them."

For Angina "I am a 76-year-old with angina or chest pain and blood pressure. I have been taking 30 mg of this medication for about a month. I experienced a tension headache in the back of my head, but cut the pill in half and take it morning and night together with losartan 50 mg and feel much better."

Isosorbide mononitrate for Angina "Two stents and a blockage they couldn’t fix because it was small. Constant chest pain/pressure after exercise. Cardiologist prescribed this. Dull headache on day one, very similar to a Nitro pill. If you’ve taken Nitro, you know what I mean. Cardiologist said to stick with it for several weeks and take Tylenol for the headache. It’s been 9 days, and I can barely detect a headache. I don’t have any chest pain/pressure, which has been nice! I do wake up with tightness in the morning, but it goes away with another dose. I feel much better. Just power through it."
