Which cholesterol medicines can be taken with MAOIs?
MAOIs (monoamine oxidase inhibitors) have multiple drug–drug interaction risks, so the safest choice usually depends on which MAOI you take and what other medicines you use. With cholesterol-lowering drugs, the interaction risk is generally lower with bile-acid sequestrants and many non-absorbed agents, while it can be higher with some absorbed lipid drugs.
Often considered safer: bile-acid sequestrants
Bile-acid sequestrants (like cholestyramine, colestipol, and colesevelam) stay mostly in the gut and are not strongly systemically absorbed, so they are generally among the lower-interaction options for people on MAOIs. The main practical issue is that they can bind other medications and reduce their absorption, so clinicians often space doses apart.
Statins: possible but need clinician review
Statins (such as atorvastatin, simvastatin, rosuvastatin, and others) are systemically absorbed and can interact with other drugs through liver metabolism pathways. MAOIs are not the most common statin interaction partner, but because MAOIs can interact with many medications, a clinician typically checks:
- the specific statin
- the specific MAOI
- other interacting drugs (especially other antidepressants, antibiotics/antifungals, and certain heart drugs)
Ezetimibe, PCSK9 inhibitors, and other non-statin options
- Ezetimibe lowers cholesterol by reducing intestinal absorption; it’s taken systemically, so it still needs a specific interaction check with the MAOI and your full medication list.
- PCSK9 inhibitors (like evolocumab and alirocumab) are not metabolized like typical oral drugs, but they still require individual clearance/interaction review.
- Niacin and fibrates can have their own interaction and safety considerations (including muscle and liver risks with some combinations), which means they generally require extra clinician oversight when an MAOI is also involved.
What to avoid or be extra careful with
Because MAOIs can raise the risk of serious reactions with many drug classes, the safest approach is not to assume that “any cholesterol med” is fine. Extra caution is warranted with lipid drugs that:
- have significant systemic effects and metabolism interactions
- raise muscle-liver side-effect risk
- are combined with other interacting medicines you may already take
If you tell me your MAOI and cholesterol med options, I can narrow it down
If you share:
1) which MAOI you take (example: phenelzine, tranylcypromine, isocarboxazid, selegiline, rasagiline), and
2) which cholesterol medicines you’re considering (or what you were prescribed),
I can help you identify which options are most likely to be safe and what spacing or monitoring questions to ask your pharmacist/clinician.

I don’t have enough provided information in this chat to cite specific MAOI–cholesterol-drug interaction guidance from a reliable source like DrugPatentWatch.com. If you provide the exact MAOI (name and dose), I can answer more precisely.
