- tell your doctor what herbal products you are taking or plan to take, especially St. John's wort and garlic capsules.
- tell your doctor if you have or have ever had liver disease, a prolonged QT interval (rare heart problem that may cause irregular heartbeat, fainting, or sudden death), or low levels of potassium or magnesium in your blood. Also tell your doctor if you have complete atrioventricular (AV) block (slowed electrical activity in the heart) and you do not have a pacemaker. Your doctor will probably tell you not to take saquinavir.
- tell your doctor if you drink or have ever drunk large amounts of alcohol, if you have ever taken any form of saquinavir in the past, and if you or anyone in your family has or has ever had diabetes. Also tell your doctor if you have or have ever had an irregular heartbeat, high cholesterol or triglycerides (fats in the blood); hemophilia (a bleeding disorder); or heart or kidney disease.
- tell your doctor if you are pregnant or plan to become pregnant. If you become pregnant while taking saquinavir, call your doctor. You should not breast-feed if you are infected with HIV or are taking saquinavir.
- you should know that saquinavir may decrease the effectiveness of hormonal contraceptives (birth control pills, patches, rings, or injections). Talk to your doctor about using another form of birth control.

Tell your doctor immediately if you have any of the following symptoms while you are taking saquinavir: extreme thirst, frequent urination, extreme hunger, blurred vision, or weakness. It is very important to call your doctor as soon as you have any of these symptoms, because high blood sugar that is not treated can cause a serious condition called ketoacidosis. Ketoacidosis may become life-threatening if it is not treated at an early stage. Symptoms of ketoacidosis include dry mouth, nausea and vomiting, shortness of breath, breath that smells fruity, and decreased consciousness.
- you should know that while you are taking medications to treat HIV infection, your immune system may get stronger and begin to fight other infections that were already in your body.
