Spain: hidden sildenafil, sibutramine and 5 mg melatonin alerts

Most were "natural" sexual-enhancement or slimming products with undeclared drugs. One was a US melatonin with 5 mg per tablet, a dose Spain treats as a medicine.

What happened

Between September and October 2026 the Spanish food safety agency AESAN and the medicines agency AEMPS published these alerts for products sold as food supplements:

DateProductProblem
2 Sepseveral slimming products (AEMPS) and food supplements (AESAN, ES2026/535)undeclared sibutramine, a weight-loss drug withdrawn in the EU for serious side effects
9 Sep“Melatonin Time Release”, Haya Labs (USA), 60 tablets (ES2026/543)5 mg of melatonin per tablet

7 OctEl Toro (AEMPS)withdrawn as an illegal product
8 Octa food supplement (ES2026/604)undeclared sildenafil
27 OctEnerup Premium (AEMPS)undeclared sildenafil
28 Octa food supplement from Peru (ES2026/654)undeclared sildenafil

AESAN advises anyone who has one of these products at home not to take it.

What it means for you

  • Hidden drugs cluster in three categories: sexual “vigour”, muscle building and weight loss, often sold online as natural products. AESAN has a separate alert category for exactly these.
  • Melatonin above 2 mg a day counts as a medicine in Spain, so 5 mg tablets imported from the US cannot be sold as supplements there. Spanish supplements stop at about 1.9 mg.
  • Before buying an unfamiliar brand, check that it is in AESAN’s public list of notified supplements and be wary of products that promise fast, drug-like effects.
  • If you took one of these products and feel unwell, tell your doctor or pharmacist.
