Drug Interaction Report

Tenofovir may cause kidney problems, and combining it with other medications that can also affect the kidney such as penicillAMINE may increase that risk. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. You should seek immediate medical attention if you develop signs and symptoms that may suggest kidney damage such as nausea, vomiting, loss of appetite, increased or decreased urination, sudden weight gain or weight loss, fluid retention, swelling, shortness of breath, bone pain, muscle cramps, tiredness, weakness, dizziness, confusion, and irregular heart rhythm. 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.

You may experience reduced absorption of penicillAMINE in the presence of food. The effectiveness of the antibiotic may be reduced. PenicillAMINE should be administered one hour before or two hours after meals and at least one hour apart from any other drug, food, or milk. This will make it easier for your body to absorb the medication.

PenicillAMINE and multivitamin with minerals should not be taken orally at the same time. Products that contain magnesium, aluminum, calcium, iron, and/or other minerals may interfere with the absorption of penicillAMINE into the bloodstream and reduce its effectiveness. You should take multivitamin with minerals at least 2 hours before or 2 hours after the penicillAMINE dose, penicillAMINE should be taken at least 2 hours before and not less than 6 hours after Suprep Bowel Prep (magnesium/potassium/sodium sulfates), or penicillAMINE and multivitamin with minerals should be taken as directed by your healthcare provider. Talk to your healthcare provider if you are unsure whether your medications contain something that could potentially interact or if you have questions on how to take this or other medications you are prescribed. 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.
