Study Details

Study Description

Brief Summary

A Randomized trial comparing two different timing of taking thyroxine in patients with Hypothyroidism during fasting the month of Ramadan.

Condition or Disease Intervention/Treatment Phase
  • Other: L-Thyroxine time B (5-15 minutes Before dawn)
N/A

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.

Arms and Interventions

Arm Intervention/Treatment
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.

Experimental: Pre-Fajr (Starting the fast)

To take thyroxine immediately before start of fast at predawn time regardless of last meal time.

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.
