Medium Chain Triglycerides (mcts) + Salmeterol
Salmeterol brand name: Serevent.
We found no known interaction between Medium Chain Triglycerides (mcts) and Salmeterol in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the label for Salmeterol states a food rule worth keeping to.
Medium Chain Triglycerides (mcts) and Salmeterol
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Salmeterol and Medium Chain Triglycerides (mcts) in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
Worth understanding: our licensed dataset holds no drug-interaction record for Medium Chain Triglycerides (mcts) at all — not against Salmeterol, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.
Medium Chain Triglycerides (mcts) safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Some Salmeterol Products Have a Food Rule — Medium Chain Triglycerides (mcts) Should Not Break It
At least one FDA label for a product containing Salmeterol says to take it on an empty stomach. Most supplements — Medium Chain Triglycerides (mcts) included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Salmeterol on its own and move Medium Chain Triglycerides (mcts) to a meal later in the day.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Salmeterol products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.
One inhalation of SEREVENT DISKUS at least 30 minutes before exercise has been shown to protect patients against EIB.
From the Dosage and Administration section of the FDA label we read for Salmeterol — where that label names a specific product, the instruction is that product's. See the Salmeterol drug page ›
A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Salmeterol page
“Salmeterol (Serevent) is the long-acting inhaler taken twice daily for asthma or COPD, and its supplement list is one I would approach with real caution. Seven of the 141 ingredients on file rate major: grapefruit can raise salmeterol levels by blocking the enzyme that clears it, St.”

About Medium Chain Triglycerides (mcts)
What is Medium Chain Triglycerides (mcts)?
- Energy and sports nutrition
- Weight management
- Ketogenic diets
- Brain and cognitive support
- Nutrition support in medical conditions
Medium chain triglycerides (MCTs) are fats from coconut or palm oil that the body absorbs and uses for energy quickly. They are widely used as an energy source, in ketogenic diets, and in some medical nutrition, but evidence for big benefits like weight loss is modest. They are generally well tolerated when taken in small, gradually increased amounts, but can cause stomach upset.

An interaction check asks whether these two react with each other — it does not ask whether Medium Chain Triglycerides (mcts) is a good idea for someone in your situation. Here is what our Medium Chain Triglycerides (mcts) record says about it on its own.
Medium Chain Triglycerides (mcts): dosing
There is no single standardized dose of MCTs that fits everyone, and the right amount depends on why you are using it and how well you tolerate it.A practical approach is to start low and go slow: begin with a small amount, such as a teaspoon, and gradually increase over days or weeks to reduce stomach upset. Taking MCTs with food can also help.Always follow the directions on your specific product label, since concentrations vary between oils, powders, and capsules. If you are using MCTs as part of a medical diet, follow your doctor's or dietitian's instructions.

About Salmeterol Oral Inhalation
What Is Salmeterol Oral Inhalation Used For?
Brand name: Serevent
Serevent Diskus (salmeterol inhalation powder) is used for three main purposes: treating asthma in patients aged 4 and older alongside an inhaled corticosteroid (ICS), preventing exercise-induced bronchospasm (EIB) in patients aged 4 and older, and providing long-term maintenance treatment of bronchospasm associated with COPD — including chronic bronchitis and emphysema — in adults.
Important: Serevent Diskus is not a rescue inhaler. It will not relieve a sudden asthma or COPD attack. For asthma, it must always be used together with an inhaled corticosteroid — using it alone for asthma is contraindicated due to a serious risk of asthma-related death.
