WACO -- The heat is causing all sorts of problems for Texans.
Even prescription drugs are taking a hit.
Chris Boyd, a pharmacist, said medications vulnerable to the heat can become ineffective, putting you in danger.
"In excessive heat, if it's, like a capsule, it can melt. If it's, insulin, the heat can cause it to be ineffective," said Boyd.
Whether you leave your prescription in the car or have it shipped to your house officials say an uncontrolled climate will take its toll.
"The recommended temperature is of course room temperature, and some cases, in cases like, refrigerated items, of course they need to refrigerated as soon as possible," said Boyd.
And health experts advise those with extreme health concerns should pay extra attention.
"Heart and blood pressure, diuretics, of course diabetes medication. You know, the main medications that people take to uh to keep going," said Boyd.
There are also medications that may be working properly but could still put you at risk under the relentless sun.
"You sweat to cool your body off. Some medications can, that you take, can decrease the amount of uh, sweat that your body, thus causing your body temperature to rise instead of cool off," said Boyd.
To avoid these problems Boyd said it's important to be aware of the types of medications your taking and how they affect you.
And if you think your prescriptions are ineffective contact your pharmacist immediately.
