Semalix 14mg Tablet holds semaglutide, an oral form of GLP-1 receptor agonist. Each Semalix 14mg tablet is intended to be taken once daily. According to the instructions on the bottle, the Semalix comes only in the following tablets: 3mg, 7mg and 14mg.
It is the same type of medicine and is intended to be given to adults. Semaglutide can be effective to manage appetite and also to reduce food cravings thereby possibly leading to weight loss.
What is Semalix 14mg used for?
Semalix 14mg is a medicine that includes semaglutide. Semaglutide works by binding to a receptor called GLP-1 which plays a role in blood sugar regulation and appetite control.
Semaglutide may also be responsible for decreasing body weight through less energy intake. According to the Therapeutic Goods Administration, semaglutide may make a person less hungry and hunger can be prolonged after taking a meal so that one will not think of food for a longer time, and there will be more control on food intake and the urge to eat between meals.
Those seeking professional help on obesity or excess weight with a weight-related condition have available the Chronic Weight-Management indication of the Australian registered semaglutide product for weight loss, the weight-loss Wegovy.
How does Semalix 14mg work?
Semaglutide is a GLP-1 receptor agonist. It mimics the activity of GLP-1, a hormone involved in appetite and blood glucose regulation.
Its effects include:
- Increasing feelings of fullness
- Reducing hunger
- Reducing food cravings
- Reducing overall energy intake
- Improving blood glucose control
- Delaying gastric emptying, particularly after meals
These effects can contribute to weight loss in people who respond to semaglutide.
How to take Semalix 14mg Tablet
Semalix 14mg is taken once daily.
Because oral semaglutide absorption is very sensitive to how it is taken, the timing instructions are important:
- Take the tablet after an overnight fasting period of at least 8 hours.
- Take it on an empty stomach.
- Swallow the tablet whole.
- Use only a small amount of plain water – up to 120mL.
- Wait at least 30 minutes before eating, drinking or taking other oral medicines.
Do not split, crush or chew the tablet because this may affect how semaglutide is absorbed.
Why is the 30-minute wait important?
The tablet contains a formulation designed to help semaglutide survive the digestive tract and be absorbed. Food, drinks and other oral medicines taken too soon can reduce its absorption.
Prescribing information specifically states that waiting less than 30 minutes decreases semaglutide absorption.
Semalix 14mg dosage
Semalix 14mg is generally not the starting dose.
Prescribing information recommends:
- 3mg once daily for the first month
- Increase to 7mg once daily after one month
- After at least one month on 7mg, the dose may be increased to 14mg once daily when additional glycaemic control is required
- 14mg once daily is the maximum recommended daily dose
The 14mg tablet should therefore normally be reached through gradual dose escalation rather than used as the first oral semaglutide dose.
Do not take two 7mg tablets to make a 14mg dose, and do not take more than one Semalix tablet per day.
Can Semalix 14mg help with weight loss?
Semaglutide can reduce body weight by lowering appetite and energy intake. The TGA’s assessment of oral semaglutide also describes effects on appetite, satiety, hunger and food cravings.
For chronic weight management in Australia, Wegovy has a specific indication for adults with:
- BMI ≥30 kg/m², or
- BMI ≥27 kg/m² to <30 kg/m² with at least one weight-related comorbidity.
What if you miss a Semalix 14mg dose?
If you forget to take your daily tablet, skip the missed dose and take your next tablet on the following day at the usual time.
Do not take two tablets on the same day to compensate for the missed dose. Prescribing information specifically recommends skipping a missed dose.
Common side effects of Semalix 14mg
Gastrointestinal side effects are among the most common effects associated with oral semaglutide.
These can include:
- Nausea
- Diarrhoea
- Constipation
- Vomiting
- Abdominal pain
- Indigestion
- Reduced appetite
It is often noticed that gastrointestinal symptoms get more prominent when the dose goes up. According to prescribing information, there were cases of serious gastrointestinal reactions, and the information recommends being careful with people who have severe gastroparesis.
When should you seek medical attention?
Seek medical advice if you experience:
- Severe or persistent abdominal pain
- Repeated vomiting
- Severe or ongoing diarrhoea
- Symptoms of dehydration
- Significant changes in vision
- Signs of a serious allergic reaction
- Severe or persistent stomach problems
Severe abdominal pain that may radiate to the back can be a warning sign of pancreatitis. Semaglutide has also been associated with gallbladder problems and kidney injury related to dehydration from gastrointestinal side effects.
Precautions before using Semalix 14mg
Tell your doctor before taking Semalix if you have:
- A personal or family history of medullary thyroid carcinoma
- Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)
- Previous pancreatitis
- Gallbladder disease or gallstones
- Severe stomach-emptying problems or gastroparesis
- Kidney disease
- Liver disease
- Diabetic retinopathy
- A history of serious allergic reactions to semaglutide
Semalix is contraindicated in people with a personal or family history of medullary thyroid carcinoma or MEN 2, and in people with hypersensitivity to semaglutide or its ingredients.
Pregnancy
Tell your doctor if you are pregnant, planning pregnancy or breastfeeding.
Semaglutide should not be used during pregnancy. For semaglutide products used for weight management, Australian product information recommends stopping treatment at least 2 months before a planned pregnancy.
Semalix 14mg and other medicines
Semaglutide can delay gastric emptying and may therefore influence the absorption of some oral medicines.
Tell your healthcare professional about all medicines you take, particularly:
- Insulin
- Sulfonylureas
- Levothyroxine
- Warfarin or other coumarin medicines
- Other diabetes medicines
- Other GLP-1 receptor agonists
When semaglutide is used with insulin or a sulfonylurea, the risk of hypoglycaemia can increase. Dose adjustments and blood glucose monitoring may be required.
Semalix 14mg and surgery
If you undergo an operation or procedure that requires anaesthesia or sedation, it would be better to let your doctor, surgeon or anaesthetist know that you have been using Semalix.
Semaglutide slows stomach emptying and there have been cases of patients receiving GA/DS and GLP-1 receptor agonists who have experienced pulmonary aspiration. Your healthcare team can help decide on the best way to manage the situation before the procedure takes place.
How to store Semalix 14mg
According to current prescribing information, Semalix tablets should be stored at a temperature not exceeding 30°C.
Keep the tablets:
- In the original blister pack
- Protected from moisture
- Protected from light
- Away from children
- Within the expiry date
Australian Rybelsus information similarly specifies storage below 30°C.
Frequently Asked Questions
1. Can Semalix 14mg be started directly if I have already used semaglutide injections?
Not without medical advice. Injectable and oral semaglutide have different dosing schedules and absorption characteristics. A doctor should determine the appropriate oral dose when switching from an injectable semaglutide product rather than assuming the previous injection dose converts directly to 14mg.
2. Does Semalix 14mg usually reduce appetite more than the 7mg tablet?
Different people react to medicine with variation depending on how high the dose used is. The fact that a larger dose brings stronger effects for some, the response is unique. The 14 mg dose should not be taken merely to lose appetite faster.
It is only advised and appropriate to move up to higher doses of medication after a patient has been receiving lower ones over at least one month.
3. What should I do if I vomit soon after taking Semalix 14mg?
Refrain from taking an extra pill at once. Getting an extra dose might mean you end up with more than what you were told to take. If you vomit the pill immediately afterwards or if it happens again, talk to your doctor or pharmacist for their advice.
4. Can Semalix 14mg be used after weight-loss surgery?
We have very little understanding of the use of semaglutide in people who had bariatric surgery and the prescription says there is no information on patients having had bariatric surgery. You should discuss the use of this medication with your specialist rather than starting it on your own.
5. Can Semalix 14mg affect the kidneys if I am not drinking enough?
It can become a concern indirectly. Nausea, vomiting or diarrhoea can cause fluid loss and dehydration, which may contribute to acute kidney injury. This is particularly important during dose initiation or escalation. Seek medical advice if you cannot maintain adequate fluid intake or have persistent vomiting or diarrhoea.
