Moringa may reduce the effectiveness of Progynova (estradiol). This could lead to your hormone replacement therapy or contraception not working as well as it should. Additionally, both substances are processed by the liver, which could theoretically affect how much of the medication stays in your bloodstream.
Why this happens
Moringa oleifera is thought to have 'antioestrogenic' properties, meaning it may block or interfere with the way oestrogen works in the body. It may also speed up the liver enzymes (specifically CYP3A4) that break down Progynova, causing the medicine to leave your body too quickly.
What you should do
You should consult your doctor before taking Moringa alongside Progynova. If you decide to use both, monitor for signs that your medication isn't working, such as a return of menopause symptoms or breakthrough bleeding.
Important precautions
Blood clots and stroke
Progynova significantly increases your risk of developing blood clots in the legs (DVT) or lungs (PE). Seek immediate medical help if you experience painful leg swelling, sudden chest pain, or breathlessness.
Breast and endometrial cancer
Long-term use of Progynova can increase the risk of breast cancer and thickening of the womb lining. You must report any unexplained vaginal bleeding to your doctor immediately.
Pregnancy
Do not use moringa if you are pregnant or planning to become pregnant. Chemicals found in the root, bark, and flowers can cause the uterus to contract, which may lead to a miscarriage.
Diabetes
Moringa can lower blood sugar levels. If you are taking medication for diabetes, using moringa may cause your blood sugar to drop too low (hypoglycaemia).
Hypothyroidism (Underactive thyroid)
Moringa may interfere with thyroid function and reduce the effectiveness of thyroid hormone replacement medications like levothyroxine.
Food and drink warnings
Alcohol
It is best to avoid or strictly limit alcohol when taking moringa. Moringa may affect how your liver processes substances, and combining it with alcohol could increase the risk of liver strain or alter the supplement's effectiveness.
Drinking alcohol while taking oestrogen replacement therapy can lead to higher levels of estradiol in your blood than intended. This may increase the risk of side effects. It is advisable to keep your alcohol intake within recommended limits.
Grapefruit juice
Grapefruit juice can increase the levels of estradiol in your blood, which may increase the risk of side effects such as breast tenderness, nausea, or headaches. It is best to avoid large amounts of grapefruit juice while taking this medicine.

Patient picks for Drug interactions

Can I take Metformin and Ibuprofen together?
Taking ibuprofen while on metformin can increase the risk of kidney problems and a rare but serious condition called lactic acidosis. Ibuprofen can also make metformin stay in your body longer, potentially increasing its side effects.

Can I take Mounjaro and Metformin together?
When taken together, Mounjaro and Metformin can increase the risk of your blood sugar levels dropping too low (hypoglycaemia). While both drugs work to lower blood sugar, they do so in different ways, which can sometimes lead to an additive effect. Additionally, Mounjaro slows down how quickly your stomach empties, which might slightly change how your body absorbs Metformin, though this is usually not a major concern.
