Melanotan + Terbinafine
Terbinafine brand name: Lamisil.
We found no known interaction between Melanotan and Terbinafine 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 two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
Melanotan and Terbinafine
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 Terbinafine and Melanotan 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 Melanotan at all — not against Terbinafine, 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.

See Every Supplement That Interacts With Terbinafine
This page covers Melanotan only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Terbinafine page lists 72 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), Beer (major), Siberian Cocklebur (major), Wine (major) and Ashwagandha (moderate).
By severity: 4 major · 45 moderate · 23 minor.
From our pharmacist’s overview on the Terbinafine page
“Liver strain is the risk that dominates this list. Terbinafine (Lamisil), the antifungal most people take for months to clear a nail infection, can injure the liver in rare cases on its own, and 38 of the 72 supplements catalogued here carry liver risks that could stack on top of that.”

About Melanotan
What is Melanotan?
- Skin tanning
- Reducing sun exposure for tanning
- Erectile dysfunction (Melanotan II)
- Appetite or body composition (unproven)
Melanotan is a lab-made synthetic peptide (not an herb) marketed online to darken the skin and, in one form, to aid erections. It is not approved or regulated as a supplement, its purity and dosing are unreliable, and it has been linked to serious safety concerns, so we do not recommend using it.
Synthetic peptide (laboratory-made) · Injectable solution, nasal spray (sold illicitly online)
An interaction check asks whether these two react with each other — it does not ask whether Melanotan is a good idea for someone in your situation. Here is what our Melanotan record says about it on its own.
Melanotan: dosing
There is no established, safe, or standardized dose for Melanotan, and no health authority recommends its use as a supplement. The products sold online do not have reliable dosing instructions, and the actual amount of peptide in a vial can vary widely.Because of the safety concerns and lack of regulation, we do not provide dosing guidance for Melanotan.

About Terbinafine
What Is Terbinafine Used For?
Brand name: Lamisil
Terbinafine tablets are used to treat onychomycosis — a fungal infection of the fingernails or toenails caused by dermatophytes (a type of fungus). Before starting the tablets, a doctor will confirm the diagnosis with a nail test.
Topical terbinafine products — creams and sprays — treat athlete's foot (tinea pedis), jock itch (tinea cruris), and ringworm (tinea corporis) on the skin. They also relieve the itching, burning, cracking, and scaling that come with these infections. Lamisil AT Spray is indicated for athlete's foot between the toes specifically; its effectiveness on the bottom or sides of the foot is unknown.
Most-Reported Side Effects for Terbinafine
From FAERS, the FDA’s public side-effect reporting system (8,847 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
