Side Effects of Scopolamine Patch
- One of the common adverse effects is blurred vision and changes in accommodation of the eye. This is one of the reasons why people that are using a transdermal scopolamine patch are strictly told not to operate any motor vehicle.
- A person may also suffer from dizziness and drowsiness while using a scopolamine patch.
- One of the other adverse effects is dry mouth. Although this dryness is not severe enough to cause problems like difficulty swallowing, it is severe enough to lead to slight changes in perception of taste.
- This drug may cause decreased amount of sweating (due to the anticholinergic effect), constipation, etc.
- There are certain local side effects that are seen when using a transdermal patch. These include itching and redness of skin and/or irritation in the region where the patch is present. At times, the person may suffer from dermatitis as well.
- In some patients, withdrawal symptoms may be seen associated with this patch, especially if it has been worn for more than three days. These withdrawal symptoms are seen due to the sudden spurt of cholinergic activity. The symptoms seen include nausea, vomiting, paresthesis, hypotension, etc.
- One of the potential side effects is that the absorption and action of certain oral medications that may be taken concurrently could be greatly hampered. This is because one of the mechanisms of action of scopolamine is by decreasing the motility of the gastrointestinal tract. So, the absorption of some drugs may be hampered, which could lead to its own set of side effects.
- In rare cases, a person may suffer from some severe conditions, which may include hives, rashes, difficulty breathing, tightness in the chest, skin irritation and itching, facial and body swelling, etc. In this case, he needs to immediately stop using the patch and should visit the doctor to get his condition evaluated.
