Capoten Drug Interactions Explained
The following sections explain in detail the potentially negative interactions that can occur when
Capoten is combined with any of the drugs listed above.
Diuretics
When taking Capoten with a diuretic, your
blood pressure may decrease too much. This is more likely to occur when Capoten is first started. In order to decrease the chances of this interaction, your healthcare provider may change the dosage of either medicine, start you on a lower dose of Capoten, and/or monitor you more closely.
Injectable Gold
Reactions have been reported in people taking Capoten who received gold injections. These reactions included symptoms such as facial flushing, nausea, vomiting, and low blood pressure.
Lithium
Capoten may increase the risk of
lithium toxicity and may increase the
lithium levels in the blood. Your healthcare provider may choose to monitor your blood lithium levels more frequently and may need to adjust your
lithium dosage.
Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)
Capoten can interact with
NSAIDs in several ways. The combination could cause your blood pressure to increase or may cause swelling (edema), especially if you have
congestive heart failure (CHF). If you are elderly, have kidney disease or kidney failure, or are taking a diuretic ("water pill") or are dehydrated, taking NSAIDs and Capoten together may cause kidney failure. Talk to your healthcare provider about this potential drug interaction before taking these medications together.
Potassium
If you are taking a potassium product together with Capoten, the levels of potassium in your blood may become too high. This can cause serious problems. For your particular situation, talk to your healthcare provider about using potassium and Capoten together.
