FAQ
What pack sizes does Omnicef 300mg come in?
Omnicef comes as 300mg capsules in packs of 10 to 180. It is generic cefdinir, not the original Omnicef. Larger packs cost less per capsule.
How do I pay for Omnicef delivery to Hong Kong?
You can pay for Omnicef by Visa, Mastercard or American Express on a secure, encrypted payment page, or with Bitcoin or Ethereum. Card details never reach the shop's servers. Every order ships in plain, unbranded packaging with nothing outside about the contents.
Is Omnicef the same as cefdinir?
Yes. Omnicef is a brand name; cefdinir is the ingredient inside it, and each capsule holds 300mg. A liquid suspension of cefdinir is also stocked, which is the form usually given to children; same ingredient, different brand name.
What should I do if I miss a dose of Omnicef?
Take the capsule when you remember, provided the next one is still several hours away. If your next dose is close, leave the missed one and carry on as usual — doubling up can upset your stomach and does not make the treatment work faster.
Can I stop taking Omnicef once I feel better?
No. Symptoms often lift within a few days, but the bacteria behind them take longer to clear, so it is worth finishing the course. Stopping early leaves the tougher bacteria alive, which is how an infection comes back and how the same antibiotic stops working.
Does Omnicef help with a sore throat or a cold?
Only if bacteria are behind it. Streptococcus is the usual bacterial cause of a sore throat, and cefdinir covers it. Colds, flu and most sore throats are viral, so the capsules will not ease them or shorten them.
About Omnicef
What Omnicef capsules are for
Omnicef is the brand name for cefdinir, an antibiotic belonging to the cephalosporin group. It attacks the wall that holds a bacterium together, so the cell breaks apart instead of multiplying. It is used for flare-ups of chronic bronchitis, pneumonia caught outside hospital, sinus infections, strep throat, tonsillitis, and skin infections such as infected hair follicles. Colds, flu and other viral illnesses are not affected by it. Every cefdinir product sold here is on the cefdinir page.
Taking the capsules
Omnicef comes as 300mg capsules, one swallowed whole with a glass of water. Meals do not affect absorption, so breakfast or no breakfast makes no difference. How often depends on the infection: every 12 hours for some, once a day for others, for 5 to 10 days in total. When the fever or pain eases on day two or three, the bacteria still alive are the hardiest ones, and a short course leaves exactly those to multiply again.
Unwanted effects
Loose stools are the complaint that comes up most, sometimes along with nausea, an unsettled stomach or a headache. Antibiotics can also bring on thrush or vaginal itching. A red tinge to the stool is a harmless cefdinir quirk rather than bleeding. Two problems need urgent care: diarrhoea that turns watery or bloody or arrives with fever and cramping, which can start during treatment or as late as two months afterwards; and signs of a serious allergic reaction — spreading hives, a puffy face, lips or tongue, or trouble breathing or swallowing.
What to space out from your dose
Cefdinir and iron do not mix well. Iron tablets, iron-fortified cereal and multivitamins with iron all reduce how much cefdinir is absorbed, and so do antacids made with magnesium or aluminium. Keep these at least two hours away from a capsule. Cefdinir is not for anyone who has had a dangerous reaction to a cephalosporin.
Keeping your capsules
Screw the cap back on after every dose and keep the bottle out of light and out of reach of children and pets. Capsules that are left over should not be saved for a later illness, since this antibiotic suits the infection you have now.
