Drug Interaction Report

Galantamine can occasionally cause excessively slow heart rate and low blood pressure, and using it with bisoprolol may increase that risk. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, or irregular heartbeat during treatment with these drugs, whether together or alone. 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.

Galantamine should be taken with food, and you should drink plenty of fluids throughout the day to reduce the severity of certain side effects such as nausea, vomiting, diarrhea, loss of appetite, and/or weight loss. Extended-release formulations should be swallowed whole (i.E., do not crush, chew, or divide the pill) and are often recommended to be taken in the morning. You should speak with your healthcare provider before using grapefruit products (fruit, juice, supplements) with galantamine as they may increase the blood levels and side effects of galantamine. You should also contact your healthcare provider if you experience changes in your heart rate, seizures, difficulty breathing, trouble urinating, dizziness, fainting, nausea, vomiting, diarrhea, and/or unexpected weight loss. 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.

Bisoprolol and ethanol (alcohol) may have additive effects in lowering your blood pressure. You may experience headache, dizziness, lightheadedness, fainting, and/or changes in pulse or heart rate. These side effects are most likely to be seen at the beginning of treatment, following a dose increase, or when treatment is restarted after an interruption. Let your doctor know if you develop these symptoms and they do not go away after a few days or they become troublesome. Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. 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.

Using bisoprolol together with multivitamin with minerals may decrease the effects of bisoprolol. Separate the administration times of bisoprolol and multivitamin with minerals by at least 2 hours. If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications. 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.
