Heat-vulcanized silicone dosage forms adapted for the continuous and controlled release of iodine values, notably to domestic water supplies for the treatment of the various disease states attributed to iodine deficiency, are shaped from (A) a diorganopolysiloxane matrix resin containing at least two vinyl groups bonded to silicon per molecule and having a viscosity of at least 500,000 mPa.s at 25.degree. C.; (B) at least one organohydropolysiloxane containing at least three hydrogen atoms bonded to silicon per molecule; (C) a reinforcing amount of a filler material therefor; (D) a catalytically effective amount of a platinum group metal catalyst; and (E) a therapeutically effective amount of at least one water soluble, nontoxic, organic and/or inorganic iodine compound which is in solid or liquid state at ambient temperature.
