Relevance: 27.01.2023 Reviewer: Shkutko P.M., M.D., in

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Consumer:

Both sibutramine and phenylephrine can increase blood pressure and heart rate, and combining them may enhance these effects. Talk to your doctor if you have any questions or concerns, particularly if you have a history of high blood pressure, irregular heart rhythm, or heart disease. 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. 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.

Professional:

MONITOR: Additive or synergistic effects on blood pressure and heart rate may occur when sibutramine is combined with sympathomimetic agents such as nasal decongestants, adrenergic bronchodilators, ophthalmic vasoconstrictors, and systemic vasopressors. Sibutramine is a potent inhibitor of norepinephrine and serotonin reuptake, and a less potent inhibitor of dopamine reuptake. In placebo-controlled obesity studies, sibutramine 5 to 20 mg once daily was associated with mean increases in systolic and diastolic blood pressure of approximately 1 to 3 mmHg and mean increases in pulse rate of approximately 4 to 5 beats per minute relative to placebo. Larger increases were observed in some patients, particularly when therapy was initiated at the higher dosages. However, use with sympathomimetic agents has not been formally evaluated.

MANAGEMENT: Caution is advised if sibutramine is coadministered with other drugs that can increase blood pressure and/or heart rate. Blood pressure and pulse should be measured prior to initiating therapy with sibutramine and monitored at regular intervals thereafter. Dose reduction or discontinuation of sibutramine should be considered in patients who experience a sustained increase in blood pressure or pulse rate.
