Interactions between your drugs

Major

bendroflumethiazide levomethadyl acetate

Applies to: Flumezide (bendroflumethiazide / rauwolfia serpentina) and levomethadyl acetate

Using levomethadyl acetate together with bendroflumethiazide can increase the risk of an irregular heart rhythm that may be serious. If your doctor prescribes these medications together, you may need regular monitoring of your electrolyte (magnesium, potassium) levels as well as other tests to safely use both medications. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, or fast or pounding heartbeats during treatment with levomethadyl acetate. In addition, you should let your doctor know if you experience signs of electrolyte disturbance such as weakness, tiredness, drowsiness, confusion, muscle pain, cramps, dizziness, nausea, or vomiting. 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.

bendroflumethiazide rauwolfia serpentina

Applies to: Flumezide (bendroflumethiazide / rauwolfia serpentina) and Flumezide (bendroflumethiazide / rauwolfia serpentina)

Before taking bendroflumethiazide, tell your doctor if you also use rauwolfia serpentina. You may need dose adjustments or special tests in order to safely take both medications together. The blood pressure lowering effects of this combination may be additive. You should take rauwolfia serpentina at bedtime and to notify your doctor if have dizziness or feel faint.

Drug and food interactions

Major

levomethadyl acetate food

Applies to: levomethadyl acetate

Do not consume grapefruit or grapefruit juice during treatment with levomethadyl acetate unless directed otherwise by your doctor. Grapefruit juice may increase the blood levels of levomethadyl acetate. This can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening, although it is a relatively rare side effect. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). You should also avoid alcohol during treatment, as it may add to the central nervous system effects of levomethadyl acetate and increase the risk of serious side effects such as respiratory depression, low blood pressure, fainting, coma, and even death. Do not drive, operate machinery, or perform other hazardous activities until you know how the medication affects you. Talk to your doctor if you have any questions or concerns. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during 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.

Bendroflumethiazide and ethanol 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.
