The Regionale Gezondheidsdienst is Suriname's regional primary-health service, and it is the organisation a visitor is most likely to need without ever learning its name. It runs 45 pharmacy locations inside its health centres and clinics along the coastal strip from Albina to Nickerie — three of them, Rust en Werk, Malangweg and Adhinweg, are currently not operational — supplied from a central store on Kasabaholoweg, with mobile pharmacy days at some outlying clinics.
More useful still, the RGD publishes the weekend on-call roster. Its wachtdienst page lists the duty GPs for the coming weekend district by district, with clinic addresses and both practice and home telephone numbers, and names the duty pharmacies (wachtapotheken) with their addresses.
Read the windows carefully, because they are narrow: duty surgeries and duty pharmacies open on Saturdays, Sundays and public holidays from 09:00 to 10:00 and again from 17:00 to 18:00. Outside those hours the duty doctors deal with emergencies only.
If you need a doctor or medicine at a weekend in Suriname, that page — refreshed every week — is where the answer is.
