Contraceptive injection: method can prevent pregnancy for up to three months

Fortunately, options to avoid pregnancy abound! Although the contraceptive pill and condoms are the most frequent choices, there are a number of alternatives on the market. One of them is the contraceptive injection, considered a good resource especially for those who forget to take the pills daily.

But do you know this method? Do you know how it really works? Do you have questions about effectiveness or possible side effects?

So, pay attention to this post. I’ll explain the pros and cons of the contraceptive injection to help you make a conscious decision.

How does contraceptive injection work?

Like the pill, birth control is a hormonal method to prevent pregnancy. That is, it does not form a barrier that prevents the sperm from reaching the organs where fertilization can happen.

However, these hormones cause a number of changes in the woman’s body. In some cases, ovulation does not happen.

These substances also thicken the mucus in the cervix, making sperm more difficult to pass through this entrance. Therefore, a set of changes in the female body makes pregnancy impossible.

Basically, there are two types of contraceptive injection: monthly and quarterly.

The first is made up of a combination of two hormones: estrogens and progestamens. The contraceptive applied every three months is made of progesterone (medroxyprogesterone acetate).

How is the contraceptive injection given?

Injectable contraceptives must be applied to the muscle, especially the glutes. This application must always be done by a health professional and under the guidance of the doctor.

It is very important that the application happens between the first and the fifth day of menstruation . If there is a failure related to these dates, the method may not be as effective.

Doctors explain that if the woman takes the contraceptive between the first and the fifth day of the cycle, the effect of the method is immediate. However, if they apply on any other day, it is necessary to use other contraceptives, such as condoms, for at least a week.

After application, the woman should not massage the injection site, as the action of the medication may be impaired. Doctors also advise not to make hot water compresses to relieve possible pain, as protection may also fail.

What are the advantages of contraceptive injection?

For many women, the contraceptive injection is a very advantageous method. Understand why:

1. The risk of forgetting contraceptives is reduced

Who has never forgotten to take the contraceptive? Perhaps very few women can proudly raise their hands and say that they are disciplined enough not to have missed a single day.

The fact is that many women forget to buy the pill.

In the hustle and bustle of everyday life, at the moment when she is late, during a trip in which the conceptual was not placed in necessaire – these small incidents can cause major accidents.

So, the contraceptive injection ends this problem. Just apply the hormone every 30 days or 3 months to prevent an unwanted pregnancy .

2. It is an alternative for those who have adverse reactions to the pill

Not a few women report unwanted reactions to the pill.

Loss of libido , vaginal dryness and swelling are some of the symptoms, but there are even more serious effects. Therefore, in these cases, the contraceptive injection may be a better option.

3. Relieves menstrual cramps

Most users of injectable contraceptives report that the hormone relieved a number of discomforts, such as menstrual cramps and various PMS symptoms.

For them, this benefit alone is worth the use of this type of contraceptive.

Fighting disease

Many doctors claim that the contraceptive injection also prevents disease.

It is associated with reducing and combating problems such as endometrial or ovarian cancer, cysts, uterine fibroids and pelvic inflammation. Another advantage is that it stimulates the production of red blood cells, preventing anemia.

5. Possibility of not interrupting sexual life

Not all women are comfortable having sex during menstruation.

Therefore, in this stage of the cycle, they stop enjoying the moments of intimacy with their partners and sometimes avoid even going out with someone because they believe that the meeting could end in sex.

With the contraceptive injection, the woman does not ovulate and consequently does not menstruate. Therefore, she feels free to experience her sexuality with ease, without having to schedule or avoid specific days of the month.

6. Reduction of side effects

Although not everyone adapts to the method, studies show that the injection produces fewer side effects than the pill .

So, in addition to the tranquility of taking contraceptives only once a month or quarter, women feel better.

7. High efficiency

If the woman follows the injection schedule correctly without delay, the effectiveness of the method is extremely high. No method is 100% safe, but the injection can achieve a protection rate of 97%. 

What are the disadvantages of contraceptive injection?

When it comes to hormones, the fact is that each organism has a different reaction.

So even though many women adapt very well to injectable contraceptives, for others it causes a series of uncomfortable symptoms. Find out which are the main ones:

1. Possibility of changes in the menstrual cycle

Some women notice large differences in their menstrual cycle. In some cases, menstruation just doesn’t happen (amenorrhea).

Other patients face excessive bleeding. Therefore, it is important to be aware of these signals from the body and always consult the doctor.

2. Pain and discomfort

Like oral contraceptives, injectable contraceptives can cause discomfort to women.

Headaches, swollen and sensitive breasts, tired legs are some of the symptoms that lead a group to give up the method, or to accept it, but with these caveats.

3. Retention of liquids

For us women, fluid retention is already quite common in some stages of the menstrual cycle.

When using the contraceptive injection, this discomfort may be more frequent, which leads many to believe that they gained weight during use.

Disease risks

Some studies associate the use of injectable contraceptives with a greater likelihood of developing cardiovascular diseases, such as thrombosis .

This risk becomes even more significant when the woman smokes. The combination of these two factors is extremely dangerous (although this also happens with oral contraceptives).

5. Temporary loss of fertile capacity

Even after a woman stops using the injectable contraceptive, it is natural that she will not be able to conceive for a period ranging between six months and a year.

However, this loss of fertile capacity is temporary, and after some time it is possible to plan a pregnancy.

6. Impossibility of interruption

When a woman takes an oral contraceptive and experiences unusual side effects, she may stop using it immediately. After consulting the doctor, it is possible to resume the process in the next cycle or simply abandon it.

This possibility does not exist if the woman uses the injectable contraceptive.

It is simply not possible to interrupt a hormonal process that has already started. So, if she feels bad, she needs to wait 30 days or three months for the effect to wear off gradually.

7. Falling libido

It is not uncommon for patients to report a drop in libido after using the contraceptive injection.

This is one of the adverse effects of the hormone. However, it is important to remember that this is also a frequent complaint of those who use the pill.

Who decides on the use of the contraceptive injection?

As you can see, any method has its pros and cons. Here in this post, there was a draw: 7 advantages and 7 disadvantages.

So it is you who need to analyze each of these factors, see if the benefits are more relevant than the possible problems and talk to your doctor about it.

In fact, this is one of the differences between oral contraceptives and injectables: you will need a doctor’s prescription. When it comes to the pill, it is possible to go to the pharmacy and buy them even without a prescription, although this attitude is not recommended.

Injectable contraceptives are different, and need to be prescribed by a gynecologist. Therefore, the choice is not made only by the patient.

The professional talks to her, listens to her expectations, analyzes the individual and family medical history to identify possible risks. Only then does he prescribe the injection. 

Care is always essential!

Honey, always remember that the contraceptive injection only prevents pregnancy. It does not protect women from disease transmission.

So, if you have relationships with several partners or are in a steady relationship or marriage, but don’t put your hand on fire for your boy, don’t give up the condom!

Condoms remain the only method to prevent sexually transmitted diseases. Do not think that this is a thing of the past, because the numbers from the Ministry of Health show that the rate of contamination is growing .

AIDS, syphilis, HPV, gonorrhea, genital herpes and hepatitis B or C are some of the problems that you can avoid using a condom.
