What drugs cause phantom smells? (2023)

What can phantom smells be caused by?

Phantosmia may be caused by a head injury or upper respiratory infection. It can also be caused by aging, trauma, temporal lobe seizures, inflamed sinuses, brain tumors, certain medications and Parkinson's disease. Phantosmia can also result from COVID-19 infection.

People who take 5 or more prescription medications, however, have a 69% increased odds of reporting phantom odors (OR 1.69 (1.09, 2.63)). Females aged 40–59 years have over three times the odds of phantom odor perception (OR 3.19 (2.24.

Phantosmia is also called a phantom smell or an olfactory hallucination. The smells vary from person to person but are usually unpleasant, such as burnt toast, metallic, or chemical smells.

Phantom Smells, such as odd, strong, acrid, metallic, blood-like, sour, ammonia-like, acidy, and repugnant smells, to name a few, are common anxiety disorder symptoms. Many anxious people report having phantom and odd smells as an anxiety symptom.

Smelling things that aren't there is called phantosmia. It can be unpleasant and affect how things taste. But it isn't usually serious and may go away by itself in a few weeks or months. See your GP if the strange smell doesn't go away in a few weeks.

An olfactory hallucination (phantosmia) makes you detect smells that aren't really there in your environment. The odors you notice in phantosmia are different from person to person and may be foul or pleasant. You may notice the smells in one or both nostrils.

Adults with diagnosed, but controlled, high blood pressure reported phantom odors more frequently than those without high blood pressure. We observed a threefold greater odds of phantom odor perception among adults aged 60 years and older with diabetes, but only among those who use both insulin and oral medications.

Qualitative olfactory dysfunctions, such as parosmia and phantosmia, may be clinical conditions secondary to neurological diseases. The incidence of parosmia is underestimated, as well as its association with neurological diseases, due to poor self-reporting of patients and lack of objective methods for its measure.

FDA-approved high blood pressure medications have not been reported to cause body odor.

Can MS cause you to smell things that aren't there?

People with MS can experience a variety of olfactory issues. These issues are divided into three categories: anosmia, or total loss of smell; hyposmia, or reduced sense of smell; and normosmia, or a normal sense of smell.

Phantom Smell: Sinus Infection

The phantom smell usually goes away on its own in a few weeks or months. Your doctor might suggest that you rinse your sinuses with a saltwater solution.

Or it could be an odor that isn't actually present (known as phantosmia). Your symptoms suggest you have periods of phantosmia: your brain registers an odor when none is present in the environment. But at other times, it could be parosmia, meaning you are more sensitive to a smell that doesn't bother other people.

However, a common side effect of SSRIs is increased sweating. This can lead to increased body odor, which may be particularly difficult to keep under control in warm weather.

Phantom odor perception is an olfactory disturbance in which individuals perceive an odor in the absence of a stimulus. The cause of this condition is unknown. People with phantom odor perception may have a neural signaling imbalance that allows nonsense olfactory signals to reach the central nervous system.

In primary hypothyroidism, disorders of smell and taste turn out to be frequent pathologies [10], which is confirmed also by other researchers who indicate that hypothyroidism significantly influences smell perception attenuating or even suppressing it completely.

"Phantom smells are not known to be a sign of disease," said epidemiologist and lead author Kathleen Bainbridge of the communications disorders institute. "However, we found phantom odors to be more common among people who have fair or poor health."

But your apocrine glands, usually only found in your armpit area, are activated when you're under psychological stress, explains Preti. This sweat produces a strong, sometimes even sulfurous odor when you're anxious or scared.

A: Yes, hallucination can occur as a symptom of post-traumatic stress disorder (PTSD)! For example, one documented case of such a situation was with a a client who had olfactory hallucinations; she would smell the body odor of the man who molested her as a child.

Other signs and symptoms

There is a common myth that during a stroke, the victim will perceive the smell of burning toast. The medical term for this is phantosmia; an olfactory hallucination. In other words, a phantom smell, or a smell that isn't really there.

Why do I smell smoke and there is none?

Brief episodes of phantom smells or phantosmia — smelling something that's not there — can be triggered by temporal lobe seizures, epilepsy, or head trauma. Phantosmia is also associated with Alzheimer's and occasionally with the onset of a migraine.

The term for this type of olfactory hallucination is dysosmia. Common causes of dysosmia are head and nose injury, viral damage to the smell system after a bad cold, chronic recurrent sinus infections and allergy, and nasal polyps and tumors.

Phantosmia is relatively uncommon. It makes up around 10-20% of disorders related to the sense of smell. In most cases, phantosmia is not a cause for concern and will go away on its own.

The results show that 4.2% (95% CI 3.5-5.1%) reported having experienced olfactory hallucinations, and 56% of individuals experiencing olfactory hallucinations also reported these in combination with hallucinations in other modalities.

A study that evaluated the ortho- and retronasal olfactory functions in MS patients found that 75% of the 16 investigated patients showed a quantitative olfactory disorder, 6.25% reported parosmia, and 18.75% reported phantosmia (29).
