When you begin taking ACE Inhibitors it can take a few months before you notice a good improvement in your symptoms.
Most times ACE Inhibitors do not work immediately and can take a few months to notice results.
So if you don't notice results immediately when taking ACE Inhibitors then there's nothing to worry about.
My mom who started taking ACE Inhibitors didn't really see much results until 3 months after taking the ACE Inhibitors.
Her doctor told her that it could take a few months before she noticed any significant results.
ACE Inhibitors also sometimes work faster on younger people than they do on older people but it can vary.
If you don't notice results within 4 months of taking the ACE Inhibitors then you should speak with your doctor.
