Can I take Oestrogel pump-pack and Vitamin B2 together?

Why this happens

Oestrogel is a hormone replacement therapy (HRT) absorbed through the skin into the bloodstream. Vitamin B2 is a water-soluble vitamin absorbed through the digestive tract. They are processed by different pathways in the body and do not interfere with each other's effectiveness or safety.

What you should do

You can continue to take Vitamin B2 while using Oestrogel as prescribed. No special precautions or timing adjustments are necessary.

Important precautions

Blood clots and breast cancer

You must not use Oestrogel if you have ever had breast cancer, or if you have ever had a blood clot in a vein (thrombosis) or the lungs (pulmonary embolism).

Oestrogel slightly increases your risk of blood clots (DVT/PE), stroke, and breast cancer. Seek immediate medical help if you experience sudden chest pain, breathlessness, or painful swelling in one leg.

Unexplained vaginal bleeding

Do not use Oestrogel if you have any vaginal bleeding that has not been checked and explained by your doctor.

Skin contact transfer

Do not allow other people, especially children, to come into contact with the area of skin where you applied the Oestrogel. Cover the area with clothing once dry to prevent accidental hormone transfer.

Food and drink warnings

Alcohol

It is best to avoid or strictly limit alcohol while using Oestrogel. Drinking alcohol can increase the levels of oestrogen in your blood, which may increase the risk of side effects. Additionally, long-term alcohol consumption combined with Hormone Replacement Therapy (HRT) is linked to a higher risk of breast cancer.

It is best to avoid or strictly limit alcohol when taking Vitamin B2. Alcohol can interfere with the way your body absorbs this vitamin from the digestive tract, making the supplement less effective.

Grapefruit juice

Grapefruit juice can interfere with how your body breaks down estradiol. This can lead to higher levels of the medicine in your bloodstream, potentially increasing the risk of side effects such as breast tenderness, nausea, or headaches.
