Varför detta händer

Glucosamine is a supplement used for joint health, while Oestrogel is a hormone replacement therapy (HRT) applied to the skin. They are processed by the body through different pathways and do not interfere with how the other is absorbed, used, or cleared from the system.

You can continue to use both products as directed. As with any supplement, if you notice any unusual symptoms or if you have underlying conditions like diabetes or are taking blood-thinning medication (like warfarin), you should mention your glucosamine use to your doctor or pharmacist.

Shellfish allergy

Many glucosamine supplements are derived from the shells of crustaceans. If you have a shellfish allergy, you must check the label for a shellfish-free (vegetarian) version to avoid a serious allergic reaction. Vegan or shellfish-free versions are available.

Astma

Glucosamine may worsen asthma symptoms or cause increased wheezing. If your asthma symptoms become harder to control after starting this supplement, you should stop taking it immediately.

Diabetes

Glucosamine is an amino sugar and may affect your blood glucose levels. You should monitor your blood sugar more closely when starting or changing your dose.

Taking Warfarin (blood thinner)

Glucosamine can significantly increase the blood-thinning effect of warfarin, which increases your risk of serious bleeding. Do not take glucosamine with warfarin unless specifically monitored by your doctor.

History of blood clots or breast cancer

You must not use Oestrogel if you have ever had a blood clot (thrombosis), a stroke, or breast cancer, as oestrogen can significantly increase the risk of these conditions recurring.

Intact uterus (womb)

If you still have your womb, you must also take a progestogen medicine alongside Oestrogel to prevent the risk of thickening of the womb lining and womb cancer.

Alkohol

It is best to avoid or strictly limit alcohol while using these medications. For Oestrogel, regular alcohol consumption can increase oestrogen levels in the blood, which may increase the risk of side effects. For glucosamine, while there is no direct interaction, alcohol can contribute to inflammation or stomach irritation, which may counteract the benefits of the supplement.

Grapefruit and Grapefruit Juice

Grapefruit juice can interfere with the enzymes that break down oestradiol in your body. This may increase the levels of oestrogen in your bloodstream, potentially increasing the risk of side effects such as breast tenderness, nausea, or bloating. It is best to avoid consuming large amounts of grapefruit while using Oestrogel.
