Interactions between your drugs

Major

sodium biphosphate phenyl salicylate

Applies to: Vilamit MB (hyoscyamine / methenamine / methylene blue / phenyl salicylate / sodium biphosphate) and Vilamit MB (hyoscyamine / methenamine / methylene blue / phenyl salicylate / sodium biphosphate)

The following interaction applies only to products containing sodium biphosphate that are used for bowel cleansing. It does not apply to products containing sodium biphosphate that are used for other, non-laxative related purposes.

Bowel cleansing with sodium biphosphate can cause kidney failure, in some cases up to several months after the procedure. Although it rarely occurs, the risk is increased in individuals receiving treatment with phenyl salicylate, especially if they are also elderly or frail. You may need a dose adjustment or special tests to safely use both medications. Combining these medications may also increase the risk of dehydration and electrolyte abnormalities. In severe cases, dehydration and electrolyte abnormalities can lead to irregular heart rhythm, seizures, and kidney problems. You should use sodium biphosphate exactly as prescribed by your doctor, and drink plenty of clear fluids before, during, and after the cleansing process to keep yourself hydrated. Your doctor may also recommend an electrolyte rehydration solution that you can use. Talk to your doctor if you have any concerns. 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.

Major

methylene blue safinamide

Applies to: Vilamit MB (hyoscyamine / methenamine / methylene blue / phenyl salicylate / sodium biphosphate) and safinamide

Using methylene blue together with safinamide is not recommended. Combining these medications may increase the risk of a hypertensive crisis, which is a life-threatening side effect associated with dangerously high blood pressure caused by consuming certain foods or beverages that are high in tyramine content (e.G., air dried, aged, or fermented meats; sausage or salami; pickled herring; anchovies; liver; red wine; beer; aged cheeses; sour cream; sauerkraut; canned figs; raisins; overly ripened bananas or avocados; soy beans; soy sauce; tofu; bean curds; fava beans; yeast extracts). In addition, you may have an increased risk of developing a rare but serious condition called the serotonin syndrome, which may include symptoms such as confusion, hallucination, seizure, extreme changes in blood pressure, increased heart rate, fever, excessive sweating, shivering or shaking, blurred vision, muscle spasm or stiffness, tremor, incoordination, stomach cramp, nausea, vomiting, and diarrhea. Severe cases may result in coma and even death. You should wait at least 14 days after stopping one medication before starting treatment with the other. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact. 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

Moderate

sodium biphosphate food

Applies to: Vilamit MB (hyoscyamine / methenamine / methylene blue / phenyl salicylate / sodium biphosphate)

Oral medications may not be properly absorbed when they are taken within one hour before starting sodium biphosphate for bowel cleansing. Talk to your doctor or pharmacist to see if you should adjust the dosing schedule of your other medications before you begin bowel cleansing treatment. 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.

Moderate

safinamide food

Applies to: safinamide

While you are taking safinamide, you must not eat or drink certain foods and beverages that are high in tyramine. Eating these foods while you are taking safinamide can raise your blood pressure to dangerous levels. This may cause life threatening symptoms such as sudden and severe headache, confusion, blurred vision, problems with speech or balance, nausea, vomiting, chest pain, seizure (convulsions), and sudden numbness or weakness (especially on one side of the body). Call your doctor at once if you have any of these symptoms. Foods that are high in tyramine include: air dried meats, aged or fermented meats, sausage or salami, pickled herring, and any spoiled or improperly stored beef, poultry, fish, or liver, red wine, beer from a tap, beer that has not been pasteurize, aged cheeses, including blue, brick, brie, cheddar, parmesan, romano, and swiss, sauerkraut, over the counter supplements or cough and cold medicines that contain tyramine, soy beans, soy sauce, tofu, miso soup, bean curd, fava beans, or yeast extracts (such as Marmite). Talk to your doctor or pharmacist if you are uncertain about what foods, if any, to avoid. 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.

Moderate

hyoscyamine food

Applies to: Vilamit MB (hyoscyamine / methenamine / methylene blue / phenyl salicylate / sodium biphosphate)

Ask your doctor before using hyoscyamine together with ethanol. Use alcohol cautiously. Alcohol may increase drowsiness and dizziness while you are taking hyoscyamine. You should be warned not to exceed recommended dosages and to avoid activities requiring mental alertness. If your doctor prescribes these medications together, you may need a dose adjustment to safely take this combination. 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.
