Finasteride Side Effects

The enzyme inhibitor Finasteride turns testosterone into dihydrotestosterone. This is used in the treatment of male pattern baldness as well as an enlarged prostate but it can also cause some unpleasant side effects. Some of the side effects are both severe and common, and consumers need to be aware of them before they start using this drug.

The most common and admittedly mild side effects are chills, confusion, dizziness and sweats. Those who take it may also experience a decrease in sexual libido and may not have the same desire they once had for intercourse. This can go away after they stop taking the drug, but in more severe cases it will persist much longer and may not be treatable.

More severe symptoms are typically rare, but can still be common enough that they are of concern for patients and medical professionals alike. The medically recognised condition post-Finasteride is characterised by a complete loss of sexual desire, decreased mental acuity and the development of female characteristics in male patients. In some cases, these conditions cannot be effectively treated, and they may persist throughout the rest of the patient’s lifetime.

These side effects may not be obvious right away, so patients are advised to instead watch for these lesser side effects that can lead up to something more severe. They include hives, welts, skin rashes, unexplained weight gains or losses, tingling sensations in the extremities, lumps and soreness in the breast and irregularities in the nipple.

Men need to be aware that there is the potential for severe side effects with this drug, and they should get help immediately if they start to experience any of the more severe symptoms. Some side effects are more likely to occur if the patient is using the drug at high doses or engaging in improper use. Finasteride should only be taken according to the given directions, and if there is any sign of a severe side effect, the patient should stop taking the drug right away and seek help. It may be possible to treat the side effects before they become severe.

If you have any medical conditions that you are currently being treated for, you should not take Finasteride without medical advice. The drug can have severe and unpleasant interactions with some medications, and a doctor will be able to tell you if it is safe for you to take it or if you need to seek an alternative treatment method.

Some mild side effects are to be expected, but patients should not hesitate to get help as soon as they experience something severe from taking the drug.

Acne: Diagnosis, Causes and Treatment

Acne is a very common skin condition characterised by the appearance of spots and pimples on and around the face.

All About Cystitis

Cystitis is a medical term for bladder inflammation. While most of the time, inflammation is caused due to bacterial infection, often it can be caused by secondary factors. It is very common in women, and very rare in men. More than 50% of women experience cystitis at least once in their lives.

Altitude Sickness: Symptoms, Causes and Treatment

Have you ever felt weak or suffered from a headache when you rode on a plane? Or maybe you felt sick to your stomach and lost your appetite when you hiked up to an elevated location. If something like this has ever happened to you, then you may have been experiencing altitude sickness. This is a general feeling of un-wellness, characterized by specific symptoms, that only affects certain people when they move to high altitudes.

Bladder Infection Home Remedies

While many people who are suffering from cystitis turn to their doctor for a medical treatment, many others prefer to try an alternative bladder infection treatment. Although there’s doubt that a natural bladder infection treatment will work, some of them have been effective, especially when treating mild forms of the condition. However, to best prevent the spread of cystitis, and further complications such as kidney infections, we recommend seeking confirmed medical treatments such as ... Read more
