Patient Leaflet(s)

Sandrena Gel is a female Hormone Replacement Therapy or HRT solution which contains the hormone oestrogen. Sandrena is used to relieve the symptoms of the menopause, including issues like hot flushing, and general discomfort. Sandrena will only be prescribed to patients who feel as though their menopause symptoms are hindering their quality of life.  

What is Sandrena? 

Sandrena gel is an HRT (Hormone replacement therapy) which contains a synthesised version of the female hormone oestrogen. As women get older and their ovaries begin to produce less oestrogen, the declining levels can lead to symptoms like night sweats, hot flushes, irregular periods, vaginal dryness, and mood swings. Sandrena gel can be given as a supplement to women suffering from oestrogen to replace the levels that are dropping in the body and keep symptoms to a minimum. HRT is typically only required for a short period of time, and its use must be reviewed regularly with a doctor. Sandrena is a form of oestrogen-only HRT which is applied directly to the skin and absorbed into the blood stream.  

When is Sandrena Used? 

Because Sandrena only contains oestrogen, it's often suitable for women who have had a hysterectomy. If you have not had a hysterectomy, then your doctor will usually prescribe a progesterone medication to take alongside this substance. This is because Sandrena and oestrogen-containing drugs will increase the thickness of the womb lining. This can lead to cancerous growths if not opposed by progesterone. Progesterone is intended to reduce the impact of the Sandrena on the womb lining and therefore lower the risk of cancer. However, the risks are not eliminated. When the womb has already been surgically removed through a hysterectomy, progesterone is not necessary as part of treatment.  

How do you Use Sandrena? 

When taking any Hormone Replacement Therapy treatment, it's important to follow the instructions provided with your medication. The Sandrena gel comes in sachets that are ready to use, and there are different strengths available depending on the nature of your symptoms and your medical background. If you're unsure about the instructions on how to take Sandrena, speak to your GP or pharmacist.  

Usually, Sandrena gel will need to be applied every day to a clean and dry area of the skin on the thigh or lower stomach. You can use the right and left sides of your body to alternate days where you spread the gel. Generally, it's recommended to spread the gel over an area about double the size of your hand. Once the gel has been applied, leave it to dry for at least five minutes before applying any clothes. Do not apply any powders or lotions to the area for at least an hour after application. Do not apply the gel to the vaginal area, face, or breasts. After applying Sandrena, wash your hands and avoid contact with the eyes. Do not let someone else apply this substance for you and avoid contact with other people (particularly men) after applying. You should also attempt to apply Sandrena at about the same time each day.  

What Dosages are Available? 

Your doctor will prescribe the correct dose of Sandrena based on an evaluation of your symptoms. The usual dose is 1 to 5 mg of Sandrena a day.  

If you forget to use this substance at your usual time and it's less than 12 hours late, you can apply the missed dose as soon as possible. If you're more than 12 hours late applying your dose, carry on with the next dose as normal. Do not apply double the dose of Sandrena to make up for the missed dose.

What are the Side Effects of Sandrena? 

Most people will not experience any serious side effects as a result of using Sandrena. However, like any medicine, it is possible that you will notice some unwanted outcomes. For instance, it's common to experience issues like: 

  • Skin irritation at the site of the application 
  • Fluid retention and swelling 
  • Vaginal thrush 
  • Increase in uterine fibroids 
  • Nausea and vomiting 
  • Bloating and flatulence 
  • Mood changes like anxiety and depression 
  • Dizziness and fatigue 
  • Changes in sex drive 
  • Migraine or headache 
  • Breast pain or tenderness 
  • Menstrual bleeding or spotting 
  • Weight changes 

You may also notice some slightly less common side effects, including skin reactions like rashes and itching, or irregular brown patches on the skin. Some people notice a rise in blood pressure. Some more serious side effects include disturbances in liver functioning, which may lead to yellowing of the skin or eyes. Additionally, there's a possibility for inflammation of the pancreas, blood clots, and an increased risk of gallbladder disease. Some people taking Sandrena may experience a steepening of the curvature in their corneas, which makes it harder for them to wear contact lenses comfortably.   

Make sure that you speak to a doctor or care provider immediately if you notice any signs of a potential allergic reaction to Sandrena. This might include sudden rashes or itching, swelling of the mouth, tongue or throat, or trouble breathing. This is not a complete list of side effects that may occur as a result of Sandrena. If you think you are experiencing side effects because of Sandrena, stop taking the substance immediately and contact your pharmacist or doctor.  

When Shouldn't You Use Sandrena? 

There are circumstances where your doctor may recommend that you don't take Sandrena. For instance, if you have a risk of developing cancer that could be stimulated by oestrogen - such as breast cancer, then Sandrena might not be right for you. If you have a history of benign breast lumps or fibroids in your womb, then your doctor may also recommend that you avoid taking Sandrena. 

Other women that may not be able to take Sandrena include: 

  • Women who are obese or very overweight 
  • Women with severe varicose veins 
  • Women with a history of endometriosis 
  • Women with severe varicose veins

  • Women with a family history of blood clots 
  • Women who suffer from severe headaches or migraines 
  • Women who suffer from inherited blood disorders 
  • Women who have unexplained brown matches appearing on their skin 

Your doctor will not prescribe Sandrena if you have a suspected or known history of breast cancer. Women with an untreated overgrowth in the lining of their womb, vaginal bleeding when the cause is not known, or women with blood disorders that could increase their risk of blood clotting will also not be suitable for Sandrena. Sandrena is not suitable for women who are pregnant or breast feeding. Additionally, your doctor will not prescribe you Sandrena if you are allergic to any of the ingredients within it. It's important to speak to your doctor carefully about your medical history so that they know whether it's a good idea to prescribe Sandrena to you.  

Does Sandrena Interact with Any Other Medications? 

Your doctor will need to assess your medical history and background carefully before prescribing Sandrena. To make sure that you are safe to take Sandrena, ensure that you tell your doctor if you're taking any other medication, including prescription drugs and over the counter medicines. You should also tell your doctor if you're taking any herbal remedies or supplements.

Sandrena can also lead to issues when taking medications that will help with lowering high blood pressure. Your blood pressure will need to be checked more often when you are taking hormone replacement therapies, including Sandrena. Additionally, this medicine can also oppose the fluid-reducing symptoms of diuretic medicines. If you are concerned that any of the medicines that you are currently taking might not interact well with Sandrena, speak to your doctor or pharmacist before continuing with this medication. Your doctor will assess all the risks in taking Sandrena for you before offering a prescription.  

Where Can You Buy Sandrena?

Before you seek out a place to buy Sandrena, make sure that you have spoken to your doctor to find out whether Sandrena is the right option for you.  

Can You Get Sandrena without a Prescription?  

Like all hormone replacement therapy treatments, Sandrena can only be obtained with a prescription. Your doctor will need to conduct a full medical assessment to find out whether Sandrena is appropriate in your condition, and whether there is a specific dose that will be best suited to you. Do not try to purchase Sandrena from a pharmacy without a prescription and do not trust any company that offers you this substance without approval from your doctor.
