Can you bring Tadalafil (Cialis, Adcirca) to Thailand?
You can bring up to 30 days' supply of tadalafil for personal use, with your prescription. In Thailand it is officially prescription-only.
Bringing it into Thailand
Allowed with a prescription, up to 30 days
Thai FDA lets travellers bring medicines that are not narcotics or psychotropic substances for their own use, up to 30 days' supply. Keep it in the original labelled packaging and carry your prescription or a doctor's letter. No Thai FDA permit is needed for this amount. If you need more than 30 days, contact the Thai FDA Medicines Regulation Division before you travel.
Getting it in Thailand
Prescription from a Thai doctor needed
Thai pharmacy references place tadalafil in the same specially controlled, prescription-only category as sildenafil. Get it through a doctor at a hospital or clinic. In September 2025 Thai FDA revoked the licence of a herbal product after finding undeclared tadalafil in it, so avoid unregistered products.
