When should I call my doctor if I am taking fosinopril?

While taking the blood pressure medication fosinopril, call your doctor if you experience:
  • swelling under the skin, sometimes involving the lips, tongue, throat, hands or feet. This condition, called angioedema, is rare but can be dangerous or even life-threatening.
  • trouble breathing or swallowing
  • hoarseness
  • an irregular heartbeat
  • yellowing of the skin or eyes
  • lightheadedness or fainting
  • fever or chills
Other serious side effects are also possible -- ask your doctor about other symptoms that should be a red flag. You should also call your doctor if less serious side effects don't go away or are bothersome. These include:
  • dizziness
  • cough
  • headache
  • fatigue
  • upset stomach
You should also contact your doctor if you have a severe attack of diarrhea or vomiting, or if you have sweated excessively or become dehydrated for any reason. Dehydration makes it more likely that your blood pressure will fall too low.

If you learn that you are pregnant, or suspect that you are pregnant, call your doctor immediately. Fosinopril can cause serious harm or be fatal to a developing fetus.
