Ace inhibs are pretty potent and can be harsh
The most common side effects are cough, elevated blood potassium levels, low blood pressure, dizziness, headache, drowsiness, weakness, abnormal taste (metallic or salty taste), and rash. It may take up to a month for coughing to subside, and if one ACE inhibitor causes cough it is likely that the others will too. The most serious, but rare, side effects of ACE inhibitors are kidney failure, allergic reactions, a decrease in white blood cells, and swelling of tissues (angioedema).
Use Atacand while you are on. It's one of the safest out there, especially since your young and your cycling.
