Vitamin Supplements Faqs Articles & Resources

What about cough drops?

Sugar-free cough drops are available, and you should use those rather than brands containing sugar. Again, you'll want to monitor your blood glucose carefully during your illness.

Is it safe for me to take a vitamin every day?

In general, taking a multivitamin is safe. Research reported in the Annals of Internal Medicine in March 2003 has shown that people with type 2 diabetes can benefit from a daily multivitamin, helping to reduce the risk of catching colds and flu. But take care that you don't exceed the recommended daily allowance of any particular vitamin. Always check with your pharmacist, even if it is a simple vitamin you're considering taking.

What if I'm congested? What medicines can I take?

Decongestants can increase blood glucose levels, so monitor carefully if you use one. There are many brands of decongestants; talk to your pharmacist about what will work best for you based on other medicines you are taking. Topical treatments or nasal sprays will typically have less of an effect on blood glucose than oral medicines. However, these products can only be safely used for about three days. Longer use can cause more congestion. Check product labels for the exact dosing.

If I do catch a cold, is it okay to take zinc lozenges?

The case for taking zinc to reduce the length and intensity of a cold is a bit sketchy. While some studies have shown that zinc lozenges help, others have shown no effect or an increase in cold duration. If you choose to take zinc, don't exceed the recommended dosage, and don't take it for longer than a few days. Prolonged self-treatment with zinc can cause nausea, vomiting, and diarrhea and can decrease HDL (good) cholesterol.

Are antihistamines safe for allergies or colds if I have diabetes?

Antihistamines will dry out your nose and eyes and reduce sneezing. Some antihistamines can cause drowsiness, but Claritin is a non-sedating antihistamine that's available over the counter. You should be fine taking an antihistamine as long as you follow the package instructions.

Is it safe for me to use topical ointments such as Vicks VapoRub when I have a cold?

Topical creams containing camphor, menthol, and eucalyptus oil can help relieve the symptoms of a cold or flu, such as stuffy nose, headache, and congestion. They are rubbed on the chest and throat and have no adverse side effects.

Are there any OTCs that will raise or lower my blood glucose?

Niacin, used to lower cholesterol, can raise blood glucose. Alcohol, found in cough syrups, can lower blood glucose if used in quantities greater than the suggested dosage. Aspirin taken in large quantities can lower blood glucose.

Should I use sugar-free medicines?

Using sugar-free OTCs can be a good idea if you have diabetes, provided you use caution. Sorbitol, often used as a replacement for sugar, can cause gastrointestinal distress and diarrhea when taken in large amounts, such as when consumed in medicines and meal replacement bars.

What can I take for an upset stomach?

The occasional use of OTC products such as Immodium and Pepto-Bismol for stomach upset or diarrhea is generally safe for people with diabetes. As with all medicines, read the labels to look for contraindications or warnings about use with other medicines you may be taking. Also, try to drink fluids, such as water or Gatorade, to prevent dehydration from diarrhea. If you experience frequent distress, let your doctor know because this can be a sign of diabetic gastroparesis, or slowed stomach emptying.

Should I get a flu vaccine each fall?

Yes. A flu shot will reduce your chances of catching the flu, and people with diabetes are at greater risk for developing complications or even dying from influenza. If you have no history of Guillain-Barre Syndrome, getting a flu shot is a good idea. (Those with egg allergies should also check with their allergist first.)

Are soy supplements safe?

Recent studies have shown that older women with diabetes may be able to lower their risk of heart disease by taking soy supplements. According to a study reported in the October 2003 issue of the journal Diabetes Care, the supplements can reduce insulin resistance and lower cholesterol in postmenopausal women with type 2 diabetes. Check with your physician before adding soy or other supplements, though.

Can I take herbal products, such as ginseng?

It's always important to let your pharmacist and doctor know if you're taking herbal products, whether as pills, in tea, or in other forms, due to the possibility of interactions between the medicines you are taking and these products. Some small studies have indicated that ginseng may lower the blood glucose levels of people with diabetes, but more research is needed to establish the benefits, if any, that ginseng offers. If you choose to take ginseng or any other herbal product, let your doctor and pharmacist know, and remind them of it whenever you discuss medications.

Are OTC sleep aids safe?

OTC sleep aids contain antihistamines. They can be taken occasionally if you have trouble sleeping. However, you should not regularly take a sleep aid to fall asleep. If you suffer from chronic insomnia, talk to your doctor.

I get corns and calluses occasionally. Should I use OTC products to remove them?

Proper foot care is crucial for people with diabetes. Inspect your feet for signs of blisters, cracks, and abrasions, and moisturize them daily. Do not use callus, corn, or wart removers. Leave treatment of these problems and foot infections to your doctor or podiatrist.

However, it is typically safe to use an OTC product to treat an athlete's foot infection. If the problem persists, talk to your doctor to find out if some other problem may be delaying the healing process.

Weight control is particularly important for people with diabetes. Can I safely use OTC weight loss pills?

In a word, no. The best way to manage weight is through a nutritious diet and regular exercise. Work with your doctor, diabetes educator, or dietitian if you have trouble losing weight or maintaining a healthy weight.

I know I should quit smoking. Are nicotine patches and gum safe?

All smokers are at risk for dire health consequences. People with diabetes are particularly vulnerable, in part because smoking decreases blood flow to the feet and increases the risk of stroke. Nicotine patches and gum should be safe for you to use, but check with your doctor first.

MANY OTC MEDICINES and products have no adverse effects for people with diabetes, but it's always safest to check with your pharmacist first about possible interactions or negative effects. For chronic conditions, let your health care provider know what you are experiencing and the treatments you have tried. Your doctor may suggest more effective alternatives.

Remember that when you have a cold, flu, or other infection, the illness itself may raise blood glucose levels. Monitoring closely will help you maintain adequate control on sick days.

OTCs don't require a doctor's approval for purchase, but they do have very real effects and should be used with caution.

What should I take when I have a headache?

There are many types of headache medicines, but some can have side effects. Aspirin, ibuprofen, ketoprofen, and naproxen can cause stomach upset, and prolonged use at higher-than-recommended dosed of ibuprofen, ketoprofen, or naproxen can contribute to kidney problems. Taking higher-than-recommended doses of acetaminophen can cause liver damage, and taking higher-than-recommended doses of aspirin can lower your blood glucose. Which product you take depends on personal preference, other medical conditions, and other medicines you take. It's best to talk to your pharmacist to determine the best pain-reliever for you.

What about topical treatments for itches, rashes, or muscle aches?

Some creams or ointments that are applied to the skin may cause or aggravate muscle pain associated with diabetic neuropathy (nerve disease). Products containing salicylic acid can cause burning and irritation. If you have painful neuropathy, products with capsaicin may provide the most relief, but can still cause momentary stinging, burning, or itching for several weeks before the real relief kicks in. It may take up to a month to find a product that works best for you.
