A sick person has to take medication several times a day and the tablets need to be dissolved under the tongue. He should take this medication for a long time and he must take it at fixed times. What should he do in Ramadhan? Would his fast be valid if he takes this medication as he does not directly swallow these pills but rather they need to be dissolved under the tongue?
These tablets are not swallowed and does not go to the stomach, accordingly it does not affect the fasting. He can take them while fasting.
