Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using this medicine, tell your doctor right away.

You should not use this medicine together with sacubitril. Do not use this medicine and sacubitril/valsartan (Entresto®) within 36 hours of each other.

Do not use this medicine at least 2 weeks before or 2 days after using flibanserin. Using these medicines together may cause serious unwanted effects.

This medicine may worsen the condition of patients with heart disease or heart rhythm problems. Check with your doctor right away if you have chest pain or tightness, decreased urine output, dilated neck veins, extreme fatigue, irregular heartbeat, swelling of the face, fingers, feet, or lower legs, troubled breathing, or weight gain. You might also feel dizzy or faint, or you might have a fast, pounding, or uneven heartbeat.

Dizziness, lightheadedness, or fainting may also occur, especially when you get up from a lying or sitting position or if you have been taking a diuretic (water pill). Do not drive or do anything else that could be dangerous until you know how this medicine affects you. If you feel dizzy, lie down so you do not faint. Then sit for a few moments before standing to prevent the dizziness from returning. If you faint, stop using this medicine and call your doctor right away.

Check with your doctor right away if you become sick while taking this medicine, especially with severe or continuing nausea, vomiting, or diarrhea. These conditions may cause you to lose too much water or salt and may lead to low blood pressure. You can also lose water by sweating, so drink plenty of water during exercise or in hot weather.

Check with your doctor right away if you have pain or tenderness in the upper stomach, dark urine, pale stools, nausea, vomiting, loss of appetite, or yellow skin or eyes. These could be symptoms of a serious liver problem.

This medicine may cause serious allergic reactions, including anaphylaxis. This can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.

Check with your doctor if you have a fever, chills, or sore throat. These may be symptoms of an infection resulting from low white blood cells.

Check with your doctor right away if you have bloody urine, a decrease in frequency or amount of urine, an increase in blood pressure, increased thirst, loss of appetite, lower back or side pain, nausea, swelling of the face, fingers, or lower legs, troubled breathing, unusual tiredness or weakness, vomiting, or weight gain. These could be symptoms of a serious kidney problem.

Hyperkalemia (high potassium in the blood) may occur while you are using this medicine. Check with your doctor right away if you have the following symptoms: abdominal or stomach pain, confusion, difficulty with breathing, irregular heartbeat, nausea or vomiting, nervousness, numbness or tingling in the hands, feet, or lips, shortness of breath, or weakness or heaviness of the legs. Ask your doctor before you use any medicine, supplement, or salt substitute containing potassium.

Make sure any doctor or dentist who treats you knows that you are using this medicine. This medicine could affect surgery or medical procedures.

Do not take other medicines unless they have been discussed with your doctor. This especially includes prescription or nonprescription (over-the-counter [OTC]) medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, and herbal or vitamin supplements, since they may increase your blood pressure.
