Black Tea and Ipratropium, Albuterol

Here is the interaction we found between these two, with the evidence behind it.

Moderate

BETA-ADRENERGIC AGONISTS

Why this applies to Ipratropium, Albuterol

Ipratropium, Albuterol falls under BETA-ADRENERGIC AGONISTS — the group Black Tea interacts with.

Theoretically, concomitant use of large amounts of black tea might increase cardiac inotropic effects of beta-agonists.
Black tea contains caffeine. Caffeine can increase cardiac inotropic effects of beta-agonists.
Severity Moderate Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Your Combivent inhaler combines two breathing medicines: ipratropium and albuterol. The albuterol part is a beta-agonist, and that's the piece that interacts here. The caffeine in black tea can add to the same kind of heart stimulation that albuterol already causes. On their own, both can speed up your heart a little, give you a jittery or shaky feeling, or make you notice your heartbeat more strongly.

I want to be honest about the evidence: this is mostly theoretical, based on how caffeine and beta-agonists work, not on strong studies. A normal cup or two of tea is unlikely to be a problem for most people. Stacking several strong teas or other caffeine sources on heavy inhaler days is where you might feel extra jittery or fast-hearted. If you notice that, mention it to your pharmacist or doctor.

About Black Tea

What is Black Tea?

  • Mental alertness and energy
  • Heart health support
  • Blood pressure and cholesterol
  • Digestive complaints
  • Weight management
  • Antioxidant support

Black tea is a popular caffeinated drink made from the fully oxidized leaves of the Camellia sinensis plant, and it contains caffeine and antioxidant plant compounds. Moderate tea drinking is generally safe for most adults and may modestly support heart health and alertness, but it is not a proven treatment for any disease. If you are pregnant, breastfeeding, sensitive to caffeine, or taking medicines, talk to your pharmacist or doctor.
