Interactions between your drugs
indinavir ↔ sildenafil
Applies to:indinavir and sildenafil
Talk to your doctor before using sildenafil together with indinavir. Combining these medications may significantly increase the blood levels and effects of sildenafil. Depending on your condition, you may not be able to use these medications together, or you may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience nausea, shortness of breath, dizziness, lightheadedness, fainting, visual disturbances, ringing in the ears, vision or hearing loss, chest pain or tightness, irregular heartbeat, and/or priapism (prolonged and painful erection unrelated to sexual activity), as these may be signs and symptoms of excessive sildenafil levels. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Drug and food interactions
Applies to: indinavir
Large amounts of food decreases the levels of indinavir in your body. Indinavir should be taken on an empty stomach, at least 1 hour before or 2 hours after a meal. This will make it easier for your body to absorb the medication. Take indinavir with a full glass (8 ounces) of water or skim milk. You may also drink juice, coffee, or tea with this medication. Drink at least 6 glasses of water each day to prevent kidney stones while you are taking indinavir. If you prefer to take the medication with food, eat only a light meal, such as dry toast with jelly, or corn flakes with skim milk and sugar. Avoid eating a high-fat meal.
Applies to: sildenafil
If you are receiving therapy with sildenafil you should avoid the regular consumption of large amounts of grapefruits and grapefruit juice. Grapefruit can raise the levels of sildenafil in your body and delay the time it takes for the medication to work. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.
