Can I take 12.5mg and Levothyroxine together?

Why this happens

Both medications are processed by the liver. Some studies suggest that sildenafil might interfere with the proteins that carry thyroid hormone through your blood, or affect the enzymes that break the drugs down, though this effect is usually very small.

You can take these medicines together, but it is important to be consistent. If you start taking sildenafil regularly, your doctor may want to check your thyroid levels (TSH test) to ensure your levothyroxine dose is still correct. Always take your levothyroxine on an empty stomach, at least 30 to 60 minutes before breakfast, to ensure it is absorbed properly.
