Detailed Description
To date there is debate regarding the best timing of L-thyroxine administration during Ramadan as sufficient evidence is lacking. This study aims to compare two-time points of levothyroxine intake during Ramadan focusing on change in TSH, satisfaction and compliance.
A prospective, randomized, open label, multicenter Study. The first group will be will be instructed to take their L-thyroxin dose as per current guidlines at breaking of fast time (sunset) with sip of water then wait 30-60 minutes to consume Iftar meal. The second group (pre-Fajer prayer), patients are going to be instructed to take L-thyroxin dose immediately before start of fast, i.e. Alfajer (dawn) regardless of Suhoor time. The values of Thyroid stimulating hormone (TSH) will be measured two weeks before Ramadan, and 2-4 weeks after Ramadan for comparison.

Active Comparator: Pre-Iftar (Breaking the fast) To take thyroxine at breaking of fast with sip of water then wait 30-60 miuntes to eat iftar (breakfast). |
Other: L-Thyroxine time B (5-15 minutes Before dawn)
Taking thyroxine at two different time points in relation to fasting and food intake; just before dawn and start of fast compared to the usual timing of 30-60minutes after the sunset breakfast meal.
