What vitamins can be taken with Levothyroxine?

Levothyroxine Sodium Tablets—commonly known by the brand name Euthyrox—are generally compatible with vitamin C and B-complex vitamins. Specific details are as follows:

Levothyroxine Sodium Tablets are indicated for the treatment of non-toxic goiter or for post-thyroidectomy prophylaxis against goiter recurrence. In most cases, Levothyroxine Sodium Tablets may be taken concurrently with vitamin C, as hypothyroidism resulting from the underlying disease often leads to reduced gastrointestinal function and subsequent vitamin C deficiency; thus, vitamin C supplementation may be prescribed per physician guidance. Additionally, patients taking Levothyroxine Sodium Tablets frequently experience increased enzymatic consumption, predisposing them to deficiencies in various water-soluble vitamins—particularly B-complex vitamins. Therefore, supplementation with a B-complex vitamin preparation is recommended, under the supervision and direction of a healthcare provider.

If patients develop symptoms such as tachycardia, palpitations, arrhythmia, or angina pectoris, they should promptly seek medical evaluation and assistance at a hospital.
