What is the most important information I should know about saquinavir (Invirase)?
Saquinavir must be taken together with another medication called ritonavir (Norvir).
You should not take this medication if you are allergic to saquinavir or ritonavir (Norvir, Kaletra).
Before you take saquinavir, tell your doctor if you have liver disease, diabetes; hemophilia, or high cholesterol, heart disease, heart rhythm disorder, or a history of Long QT syndrome.
Life-threatening side effects may occur if you take saquinavir with alfuzosin (Uroxatral), amiodarone (Cordarone, Pacerone), cisapride (Propulsid), dofetilide (Tikosyn), flecainide (Tambocor), lidocaine, lovastatin (Mevacor, Altoprev, Advicor), midazolam (Versed), pimozide (Orap), propafenone (Rythmol), quinidine (Quin-G), rifampin (Rifater, Rifadin, Rifamate), sildenafil (Revatio, for treating pulmonary arterial hypertension), simvastatin (Zocor, Simcor, Vytorin, Juvisync), trazodone (Desyrel), triazolam (Halcion), or an ergot medicine such as Ergomar, Cafergot, Ergotrate, Migranal, or Methergine.
Many other drugs can interact with saquinavir. Tell your doctor about all medications you use. Do not start a new medication without telling your doctor. Keep a list of all your medicines and show it to any healthcare provider who treats you.
HIV/AIDS is usually treated with a combination of drugs. Use all medications as directed by your doctor. Do not change your doses or medication schedule without your doctor's advice. Every person with HIV or AIDS should remain under the care of a doctor.
Taking this medication will not prevent you from passing HIV to other people. Avoid having unprotected sex or sharing razors or toothbrushes. Talk with your doctor about safe ways to prevent HIV transmission during sex. Sharing drug or medicine needles is never safe, even for a healthy person.
