Drug Interactions between Byvalson and Hemangeol
This report displays the potential drug interactions for the following 2 drugs:
- Byvalson (nebivolol/valsartan)
- Hemangeol (propranolol)
Interactions between your drugs
propranolol valsartan
Applies to: Hemangeol (propranolol) and Byvalson (nebivolol / valsartan)
GENERALLY AVOID: In the Valsartan Heart Failure Trial, the combination of valsartan with a beta-blocker and an ACE inhibitor was associated with unfavorable outcomes on morbidity and mortality in heart failure patients. The mechanism is unknown.
MANAGEMENT: The manufacturer recommends that the triple combination of valsartan with a beta-blocker and an ACE inhibitor be avoided in heart failure patients.

Drug and food interactions
propranolol food
Applies to: Hemangeol (propranolol)
ADJUST DOSING INTERVAL: The bioavailability of propranolol may be enhanced by food.
MANAGEMENT: Patients may be instructed to take propranolol at the same time each day, preferably with or immediately following meals.

valsartan food
Applies to: Byvalson (nebivolol / valsartan)
GENERALLY AVOID: Moderate-to-high dietary intake of potassium, especially salt substitutes, may increase the risk of hyperkalemia in some patients who are using angiotensin II receptor blockers (ARBs). ARBs can promote hyperkalemia through inhibition of angiotensin II-induced aldosterone secretion. Patients with diabetes, heart failure, dehydration, or renal insufficiency have a greater risk of developing hyperkalemia.
MANAGEMENT: Patients should receive dietary counseling and be advised to not use potassium-containing salt substitutes or over-the-counter potassium supplements without consulting their physician. If salt substitutes are used concurrently, regular monitoring of serum potassium levels is recommended. Patients should also be advised to seek medical attention if they experience symptoms of hyperkalemia such as weakness, irregular heartbeat, confusion, tingling of the extremities, or feelings of heaviness in the legs.

propranolol food
Applies to: Hemangeol (propranolol)
ADJUST DOSING INTERVAL: Concurrent administration with calcium salts may decrease the oral bioavailability of atenolol and possibly other beta-blockers. The exact mechanism of interaction is unknown. In six healthy subjects, calcium 500 mg (as lactate, carbonate, and gluconate) reduced the mean peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of atenolol (100 mg) by 51% and 32%, respectively. The elimination half-life increased by 44%. Twelve hours after the combination, beta-blocking activity (as indicated by inhibition of exercise tachycardia) was reduced compared to that with atenolol alone. However, during a 4-week treatment in six hypertensive patients, there was no difference in blood pressure values between treatments. The investigators suggest that prolongation of the elimination half-life induced by calcium coadministration may have led to atenolol cumulation during long-term dosing, which compensated for the reduced bioavailability.
MANAGEMENT: It may help to separate the administration times of beta-blockers and calcium products by at least 2 hours. Patients should be monitored for potentially diminished beta-blocking effects following the addition of calcium therapy.

Therapeutic duplication warnings
Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.
Beta blockers
Therapeutic duplication
The recommended maximum number of medicines in the 'beta blockers' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'beta blockers' category:
- Byvalson (nebivolol/valsartan)
- Hemangeol (propranolol)
Note: In certain circumstances, the benefits of taking this combination of drugs may outweigh any risks. Always consult your healthcare provider before making changes to your medications or dosage.
