Nelfinavir Mesylate Information
(nel fin' a veer)
Before taking nelfinavir,
- tell your doctor and pharmacist if you are allergic to nelfinavir, any other medications, or any of the ingredients in nelfinavir tablets or powder. Ask your pharmacist for a list of the ingredients.
- tell your doctor if you are taking alfuzosin (Uroxatral); amiodarone (Cordarone, Nexterone, Pacerone); cisapride (Propulsid; not available in the U.S.); ergot-type medications such as bromocriptine (Cycloset, Parlodel), dihydroergotamine (D.H.E. 45, Migranal), ergoloid mesylates (Hydergine), ergotamine (Ergomar, in Cafergot, in Migergot), and methylergonovine (Methergine); lovastatin (Altoprev); lurasidone (Latuda); midazolam (Versed) by mouth; pimozide (Orap); quinidine (in Nuedexta); rifampin (Rimactane, Rifadin, in Rifater, in Rifamate); sildenafil (only Revatio brand used for lung disease); simvastatin (Zocor, in Vytorin); St. John's wort; and triazolam (Halcion). Your doctor will probably tell you not to take nelfinavir if you are taking one or more of these medications.
- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, and nutritional supplements you are taking or plan to take. Be sure to mention any of the following: anticoagulants ('blood thinners') such as warfarin (Coumadin, Jantoven); azithromycin (Azasite, Zithromax, Zmax); bosentan (Tracleer); certain calcium-channel blocking medications such as amlodipine (Norvasc, in Prestalia, in Twynsta, others), felodipine, isradipine, nicardipine (Cardene), nifedipine (Adalat, Afeditab, Procardia), nimodipine (Nymalize), and nisoldipine (Sular); carbamazepine (Carbatrol, Epitol, Equetro, Tegretol, others); certain cholesterol-lowering medications (statins) such as atorvastatin (Lipitor, in Caduet) and rosuvastatin (Crestor); colchicine (Colcrys, Mitigare); delavirdine (Rescriptor); fluticasone (Flonase, Flovent; in Advair); indinavir (Crixivan); medications that suppress the immune system such as cyclosporine (Gengraf, Neoral, Sandimmune), sirolimus (Rapamune, Torisel), and tacrolimus (Astagraf XL, Prograf); methadone (Dolophine, Methadose); nevirapine (Viramune); certain phosphodiesterase inhibitors (PDE-5 inhibitors) used for erectile dysfunction such as sildenafil (Viagra), tadalafil (Adcirca, Cialis), and vardenafil (Levitra); phenobarbital; phenytoin (Dilantin, Phenytek); proton-pump inhibitors such as esomeprazole (Nexium), lansoprazole (Prevacid), omeprazole (Prilosec), pantoprazole (Protonix), and rabeprazole (AcipHex); quetiapine (Seroquel); rifabutin (Mycobutin); ritonavir (Norvir, in Kaletra, in Viekira Pak); salmeterol (Serevent, in Advair); saquinavir (Invirase); and trazodone. Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Many other medications may also interact with nelfinavir, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list.
- if you are taking didanosine (Videx), take it 1 hour before or more than 2 hours after nelfinavir.
- tell your doctor if you are taking birth control pills. Nelfinavir can decrease the effectiveness of oral contraceptives. You should use another method of birth control while taking this medication. Talk to your doctor about birth control while taking nelfinavir.
- tell your doctor if you have or have ever had diabetes, hemophilia (a group of inherited bleeding disorders in which the ability of blood to clot is not normal), or liver disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while taking nelfinavir, call your doctor. You should not breastfeed if you have HIV infection and are taking nelfinavir.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking nelfinavir.
- you should be aware that your body fat may increase or move to different areas of your body, such as your upper back, neck ('buffalo hump'), breasts, and around your stomach. You may notice a loss of body fat from your face, legs, and arms.
- you should know that you may experience hyperglycemia (increases in your blood sugar) while you are taking this medication, even if you do not already have diabetes. Tell your doctor immediately if you have any of the following symptoms while you are taking nelfinavir: 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.
- if you have phenylketonuria (PKU, an inherited condition in which a special diet must be followed to prevent mental retardation), you should know that nelfinavir oral powder is sweetened with aspartame that forms phenylalanine.
- 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. This may cause you to develop symptoms of those infections. If you have new or worsening symptoms at any time during your treatment with nelfinavir, be sure to tell your doctor.
- stomach pain
- loss of appetite
- difficulty breathing or swallowing
