Bethkis Side Effects
While a majority of people using Bethkis tolerate it well, side effects are possible. Common ones include abnormal breathing sounds, change in voice, and nosebleeds. In addition, there are some potentially serious reactions that you should report immediately to your healthcare provider, such as hearing loss, balance problems, and worsening muscle weakness.
Just like any medicine, Bethkis® (tobramycin inhalation solution) can cause side effects. However, not everyone who uses the medication will have problems. In fact, most people tolerate it quite well. If reactions do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Bethkis. Your healthcare provider can discuss a more complete list with you.)
Bethkis has been studied extensively in clinical trials. In these studies, the side effects that occurred in a group of people taking the drug were carefully documented and compared with those that occurred in a similar group of people taking a placebo (a inhalation with no active ingredients). As a result, it was possible to see what side effects occurred, how often they appeared, and how they compared to the placebo.
In clinical studies, the most common Bethkis side effects included:
- Decreased forced expiratory volume (a lung test that indicates worsening lung function) -- in up to 31 percent of people
- Abnormal breathing sounds -- up to 19 percent
- An increase in red blood cell sedimentation rate (a blood test that can indicate inflammation in the body) -- up to 8 percent
- Change in voice (hoarseness) -- up to 6 percent
- Wheezing -- up to 5 percent
- Nosebleed -- up to 3 percent
- Mouth and throat pain -- up to 3 percent
- Inflammation of the lining of the bronchial tubes (bronchitis) -- up to 3 percent
- Inflammation of the tonsils -- up to 2 percent
- Diarrhea -- up to 2 percent
- An increase in the level of a certain type of white blood cell -- up to 2 percent
- An increase in the level of antibodies in the blood -- up to 2 percent.
