Carob and tipranavir

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

Minor

ORAL DRUGS

Why this applies to tipranavir

tipranavir falls under ORAL DRUGS — the group Carob interacts with.

Theoretically, carob might also impair the absorption of oral drugs.
Laboratory research shows that carob, when consumed as part of the diet or used as a thickening agent in infant formula, reduces the absorption of certain minerals. Take carob 30-60 minutes after oral medications.
Severity Minor Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

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

Here's the simple version: carob is mostly a food, but it's loaded with tannins and fiber. In lab and animal studies, that fiber and those tannins can grab onto things in your gut and keep them from being fully absorbed. The worry with tipranavir (Aptivus) is that, in theory, carob taken at the same time could trap a little of the drug and lower how much gets into your blood.

Why that matters for an HIV medicine: tipranavir works by keeping the virus in check, so you really don't want its blood levels dipping. That said, this concern is theoretical and comes only from lab data, not from people. To be safe, just separate them. Take your tipranavir first, then wait 30 to 60 minutes before having carob, and run it by your pharmacist.

About Carob

What is Carob?

Carob
  • Diarrhea (especially in children)
  • Cocoa/chocolate substitute
  • Digestive upset
  • Acid reflux/heartburn
  • Source of dietary fiber

Carob is a Mediterranean tree whose pods are widely used as a caffeine-free, naturally sweet cocoa alternative and as a thickener (carob gum). It is mostly eaten as a food and is generally well tolerated, and carob pod preparations have some traditional and limited research use for diarrhea, but evidence for most medicinal claims is limited. Check with your pharmacist or doctor before using it as a treatment, especially for infants or children.

About Tipranavir

What Is Tipranavir Used For?

Brand name: Aptivus

Aptivus (tipranavir) is used to treat HIV-1 infection in adults and in pediatric patients weighing 36 kg or more who have already tried other HIV medications and whose virus has become resistant to more than one protease inhibitor. It must always be taken together with ritonavir to work properly.

Aptivus is not recommended for people who have never been treated for HIV before. It works best when combined with other active HIV medications, and a resistance test is usually done first to confirm the virus will respond to it.
