Protonix

How is this medication used?

Protonix is usually taken once daily, with or without food. The dosage and length of treatment are based on your medical condition and response to treatment. For best results, it's important to take it at the same time each day to keep a consistent level of the medication in your body. Swallow the tablet whole, without crushing, chewing, or splitting it.

What are the possible side effects?

Common side effects of Protonix include headache, diarrhea, nausea, vomiting, and gas. Serious side effects can include signs of kidney problems (such as change in the amount of urine), lupus-like symptoms (such as rash on nose and cheeks, new or worsening joint pain), and magnesium blood level changes (such as unusually fast/slow/irregular heartbeat, persistent muscle spasms, seizures).

What are the potential interactions?

Protonix may interact with drugs that rely on stomach pH for absorption (such as ketoconazole, ampicillin esters, iron salts, erlotinib), leading to reduced effectiveness of these drugs. Also, it can increase the risk of gastrointestinal infections and may interfere with blood thinning medications like warfarin, requiring closer monitoring of INR levels. Co-administration with methotrexate, especially at high doses, may increase levels of methotrexate and/or its metabolite, potentially leading to toxicity.
