<p>Promethazine Theoclate tablets can make some people feel drowsy, dizzy, confused or disorientated and this&nbsp;may reduce your ability to drive or operate machinery safely.&nbsp;Do not drive or operate machinery until you know how this medicine affects you&nbsp;and you are sure it won&#39;t affect your performance.&nbsp;If your child is affected in this way they should avoid potentially hazardous activities such as riding bikes. You should not leave your child unattended after giving them this medicine.<br />
<br />
Avoid drinking&nbsp;alcohol&nbsp;while taking Promethazine Theoclate&nbsp;because this is likely to make the above effects more likely&nbsp;or worse.<br />
<br />
Promethazine Theoclate tablets may make your skin more sensitive to sunlight than usual, so you should avoid exposing your skin to direct sunlight or sunlamps until you know how your skin reacts. If you can&#39;t avoid strong sunlight you should use a sunscreen lotion or make sure your skin is protected with clothing.<br />
<br />
This medicine may interfere with some&nbsp;pregnancy tests, causing false negative or false positive results.<br />
<br />
If you are due to have any&nbsp;skin prick tests&nbsp;to diagnose allergies you should stop taking Promethazine Theoclate at least 72 hours before the tests. This is because antihistamines can prevent or lessen the skin reactions that indicate an allergy, and so can make the test results unreliable.</p>
